Full textAbstract:
This study suggests the use of standardized sewing terms for the construction of smart sewing systems. This study analyzed the use of stitches (ISO 4915) and seams (ISO 4916) for cut and sewn knit garment which are the basic elements of sewing on an ISO basis. The results of the analysis of sewing specifications of cut and sewn knit garments are as follows. First, the use of stitches and seams were analyzed. As a result, both stitches and seams were used as non-standard terms. Second, among 3,263 stitches, ISO 4915 No. 406 followed by 401, 504, 605 were the most frequently used; however, ISO 4915 No. 514 was anticipated the most because the ISO 4915 No. 514 used for joining was not recorded in the sewing specification. Finally, the use of stitch for each seam was analyzed. The most common stitch used for ISO 4916 No. 6.02.07 was ISO 4915 No. 406. In addition, when it was sewing ISO 4916 No. 4.04.01, ISO 4915 No. 504 was used in step 1, and ISO 4915 No. 406, 602, and 605 were used in step 2. It is important to use the international standard sewing terms for the production site based on the results. In addition, the construction of smart sewing systems and the work of international standardization through industryuniversity cooperation are important for securing global competitiveness. Therefore, the use of international standard terminology and practical training should be conducted with a focus on stitching and seams with high frequency of use.

Full textAbstract:
The present research is focused to develop the relationship between the seam slippage and mechanical properties of sewn fabric by considering the spun thread and fabric configuration in the stitched assembly. Plain and twill weave fabric was used for the sample development stitch with the spun thread while the sewing machine setting was kept constant to produce a balanced seam. Different stitched samples are prepared in warp and weft direction for investigation by considering superimposed, flat, and bound seam classes with multi-thread chain, lock, and cover stitches. Experiment findings highlight the optimum load of seam slippage in N at 6 mm seam opening at stitched assembly by employing mentioned seam classes and stitch types. The results showed that 189.97 N maximum load was found at 6 mm seam opening for plain weave fabric in warp direction at flat seam sample with a lock stitched while in weft direction 80.65 N minimum load at the bound seam with multi-thread chain stitch. For twill weave fabric 94.72 N minimum slippage load at a 6 mm seam opening was observed in the weft direction at the bound seam with multi-thread chain stitch while in the warp direction maximum slippage load of 200 N was reported at the superimposed, flat and bound seam with multi-thread chain, lock and cover stitches. Established findings have a significant coefficient of determination (R2 0.90) between sewing thread extension and seam slippage load at 6 mm seam opening in both directions. The present research provides the guidelines to select the spun sewing thread which was possessed the minimum extension (%) against the respective load (N) to overcome the seam slippage in the stitched garment.

Hand stitches seams along edges of lapels, collars and pocket flaps on a men jacket help to fix canvas interlining under face fabric, keep the edges flat and prevent them from rolling or curling. Traditionally hand stitches seams also indicate high quality of the suit. Real hand stitch machines imitate had stitch 209. Depending on the length of the top and bottom stitch parts the machines can create pick stitches, saddle stitches and other stitch patterns. One group of the machines create stitches by help of a hooked needle, other machines use a double pointed needle. The machines work with limited length threads, most often with 90 cm and 120 cm long ones. The hand stitch seams can to be sewn with special waxed silk threads or regular threads. To increase work productivity and quality the machines use manual or auto thread trimming devices, reverse stitch function, half stitch option, seam beginning and end securing, programmable stitch type, sewing speed, stitch length, thread trimming time.

Sewing quality is an important factor that contributes to the overall quality of an end-product. Sewing quality compro - mises different components such as bending, seam strength, seam slippage, elasticity etc. Among these components, bending has a special importance because of causing changes in appearance, sensorial comfort and drape of a garment. Therefore, in this study, effects of stitch type and seam direction on the bending rigidities of sewn fabrics were evaluated and compared. A polyester woven fabric which is suitable for sportswear was sewn with three basic stitch types (lock stitch, chain stitch and overlock stitch), in 5 different directions (warp, weft, 30°, 45° and 60° angles). As reference, samples without stitches were tested, too. Bending properties of samples were determined via heart loop method. According to the results, sewing increased the fabric bending rigidity. The degree of bending rigidity increment was dependent on the stitch type. Highest bending rigidity values were obtained for overlock stitched samples those were approximately 4 times higher when compared to non-sewn reference samples. Thickness of sewn parts was in accordance with the bending rigidity results. For oriented seams, bias sewing especially for 45˚ oriented samples, showed the most advantageous bending results. This study showed the usability of heart loop method for sewn samples via consistent results for different stitch types and seam directions.

Seams, which are exposed to strain during the physical movement of end user, play a significant role in textile by joining the pieces of cloth and giving the garment its final shape. Seam performance and quality of a textile are critical factors affecting the final product and the end user. In this study, it was aimed to examine the effects of stitch types, stitchy density and sewing directions on seam quality of cotton sateen fabric in terms of seam strength and seam slippage and to determine the optimum conditions. It was demonstrated that 6 stitches/cm stitch density, lock stitch type and sewing in bias direction can be used for 100% cotton sateen weaved fabric in order to obtain satisfactory seam quality.

In this article the sewing needle heat is measured without sewing thread and with sewing thread at different stitch density (stitches per inch or SPI) of lock stitch sewing machine by thermocouples. Two methods are used to measure sewing needle heat, touch thermocouple method and inserted thermo couple method. Needle temperature is measured after periodic 10, 20, 30 and 60 seconds of sewing operation. Whereas the machine running at speed from 1000 r/m to 4700 r/m. It is observed that decreasing stitch length causes an increase in the temperature of the sewing needle. Stitch density shows same influence on needle for sewing with thread and without thread. It is observed from our research that at SPI of 14 the needle temperature with thread rises to 259 °C at 4000 r/min of machine. It is recommended to use minimum stitch density.

Full textAbstract:
Interlaminar shear strength and flexural bending strength of stitched and non-stitched carbon fibre reinforced polymer (CFRP) laminates were studied with reference to three different sewing threads. The preforms were stitched through-the-thickness by two different hybrid carbon fibre threads and a Zylon (polyphenylen-2,6-benzobisoxazol, PBO) thread with 16 stitches/cm2 stitch density. The short beam interlaminar shear strength of the laminate increases where as flexural bending strength of the laminate shows mixed results depending on the stitching direction. Carbon fibre threads show relatively less positive influence on the laminate properties than the PBO thread. The results of this study differ partly from the literature studies.

Purpose The purpose of this paper is to make available to the parachute industry tools to predict behaviour of certain textile materials. In addition to this, it is desired to reveal and explain the basic requirement criteria for proper textile material selection. The strength of an assembly as a whole is directly dependent on the strengths of the various joints and seams required to assemble the larger structure. Keeping in mind the complex problem of parachute construction, this research seeks to enlighten the industry about the performance of seams in nylon woven canopy fabrics. Five factors have been studied: different types of weave (plain, rip-stop and twill), density (number of stitches per centimetre), different rows of stitches with lapped seams, different types of stitches (lock stitch, chain stitch and zig-zag) and seam direction (warp, weft and bias direction). Two responses have been analysed, the seam breaking force and the seam efficiency (per cent ratio of seam strength to fabric strength). The test results were subjected to an analysis of variance and the seam strength proved to vary significantly not only with the primary parameters, but with the interactions of the primary parameters as well. That is seam strength (and seam efficiency) changes with each primary parameter but it changes in a different manner when other parameters change. Multiple regressions have been used to construct preliminary predictor equations for seam strength and efficiency, and investigations to provide better equations are in progress. Design/methodology/approach ANOVA techniques and statistical regression equations were formed. Findings The work has concluded that twill weave 9 with chain stitch has the maximum seam strength, which makes canopies made with 2/1 twill weave and stitched with lapped seam with four rows of chain stitch optimum for heavy supply droppings with a single use parachute(s). It is evident from the results that twill weave with lock stich has the maximum seam efficiency. This makes the canopies stitched with twill fabric, constructed with lapped seams and four rows of stitches ideal for parachutes to be used multiple times. The brake parachutes on aircrafts and parachutes used by sky divers and air combat soldiers can use parachutes whose canopies can be used many times made out of the above mentioned weave and stitch specification. Originality/value Original work was conducted from the woven fabrics.

Full textAbstract:
Seam strength plays a very important role in acquiring the desired quality seam which ultimately defines the quality of any clothing. The paper is aimed to study the strength of seam produced from denim fabric, how different sewing parameters like sewing thread type, type of seam, seam direction as well as the density of stitches influence the strength of seam, and it is observed that they have direct effect on lockstitch seam strength of denim fabric with various degree. For research denim fabric with 3/1 weaves structure and three different sewing threads namely 100% cotton spun with 14tex linear density, 100% polyester spun with 24tex and 60tex linear density were used. Seam class used for the research was superimposed seam prepared with two layers, SSa and three layers, SSb. The samples were made by stitching with lockstitch sewing machine both in warp and weft way. Three different stitch densities were used to sew the samples and they were-7, 9 and 11 stitches per inch. The strength of the produced seams was tested on a universal strength tester machine-the titan tensile strength tester. Test was performed according to ASTM D5034 test method. The outcome of the research shows that seam type, seam direction, thread types, and stitch density have direct effect on lockstitch seam strength of denim fabric with various degrees. Higher seam strength was obtained for the SSb type seam produced in warp direction with coarser sewing thread (60tex) and 11 stitches per inch (SPI). The influence of independent variables on the seam strength was assessed statistically using a multivariate variance analysis (ANOVA) with the help of SPSS software and it was found that they effect significantly. Regression analysis was done to develop the regression equation to predict lockstitch seam strength before production process.

Full textAbstract:
This study aimed to establish an automatic sewing process for garment production according to textile properties. An automatic feeding system and a self-made template were introduced to an industrial sewing machine. Two types of stitches were performed on fabrics with various physical properties and surface roughness using this automatic sewing machine. The appearance, stitch length and width, seam strength, and seam efficiency were evaluated according to the sewing conditions, such as presser height and sewing speed. In addition, the correlation between textile properties, sewing conditions, and sewability was analyzed to derive a regression equation for sewability. The evaluation showed no difference in the lock stitch condition. On the other hand, under the zigzag stitch condition, the stitch width differed according to the presser height, which also affected the seam structure. The optimal presser height for each fabric was derived from the experimental results. In terms of the sewing speed, however, the seam strength was the best at 200 RPM in the lock stitch and 400 RPM in the zigzag stitch. The moderating effect of the presser height between textile properties and sewability in the lock stitch condition was confirmed. This result can be used as basic data for establishing an automatic sewing process for smart factories.

As happened in Hargomulyo Village, the results of observations made by the researchers found that most tailors did not return the leftover stitches if the remaining cloth was small, if the left over seams many tailors would return it to consumers. The formulation of the problem determined is 1) What is the understanding of the tailors and consumers regarding the property rights of the remaining sewing cloth in Hargomulyo Village, Ngrambe District, Ngawi Regency? 2) What is Mashlaha Mursalah's review of the remaining stitches in Hargomulyo village, Ngrambe sub-district, Ngawi district? In this study using the field method / qualitative method (field research) because it makes direct observations while collecting data through interviews, observation and documentation. In this study using the inductive method for direct observation. The understanding of the seamstresses and consumers in Hargomulyo Village regarding the remaining sewing cloth, namely that they have the view that in general consumers never ask or ask for the remaining sewing cloth if the consumer knows that the remaining sewing cloth is small. But if there are lots of leftover stitches, new consumers ask for the remaining cloth and ask the tailor. While the understanding of the seamstress regarding the remaining stitches, that is, they have the view that in general tailors do not return the remaining stitches if the remaining is small. But if there is still a lot of cloth left, the tailor will return the remaining cloth to the consumer. Overview of Maslahah Mursalah Regarding the ownership rights of the remaining stitched cloth, that is included in the maslahah mu'tabarah because in the end the status of the remaining slightly stitched cloth is permissible when the consumer just leaves it because it is classified as matrukah goods so the tailor can take it because the previous ownership rights have been lost.

Sewing by hand is certainly something that deserves researching, conserving and practising. This traditional craft might be used to make copies of items in museums or it might be used to produce modern clothing. One source of inspiration are the seams we find on archaic textile fragments. This article deals with sewing skills and techniques that are detectable on textiles recovered from urban waste from Estonian towns dating back to the 13th–16th centuries. Our article focuses on textile fragments from Tallinn chiefly, but we also look at a small assortment of finds from Tartu and Pärnu. Our main concern is with the sewing skills and the techniques used to make woollen clothes.
Medieval sewing skills and techniques cannot really be described using contemporary terminology or manuals: any finds are only fragmentary, and establishing a link with an object is complicated because old techniques differ considerably from contemporary practice. Fragments do have their advantages, however. For example, seams can be studied more easily. The lack of adequate terminology in our contemporary language arises from the fact that many medieval techniques have been forgotten.
The main research methods we used were visual observation with the help of magnifying tools and detailed documentation. Stitches and seams leave traces, which means we are able identify them. A thread that has rotted away leaves a row of holes behind it, and the existence of seams is revealed by imprints and by an unworn surface. Furthermore, different stitches shape the joints in a different way.
The article is based on 174 woollen textile fragments with a total of 321 seams. Eight different types of stitches were identified on those fragments: running stitch, partial and full backstitch, hemming and overcast stitch, and buttonhole stitch. Running stitch occurs the most often, in fully one third of the cases.
Seams can be divided into construction seams, hems and finishes, and seams for special details. Plain seam, seam with folded seam allowances, reinforced seam, lapped seam, whip stitch joins, buttonholes and buttons are studied here. English captions are provided for the illustrations of the article.
Most of the textile fragments originate from recycling, in the course of which the seams were cut out and thrown away. Sewing waste provides information about consumption habits, and sometimes objects can be identified. Certain seams relate to certain items, e.g. the lapped seam discovered in 14 cases definitely relates to the remnants of stockings.
The standardisation of techniques was noticeable. The length of seams and the width of seam allowances seems to be similar throughout the period under study: the running stitch is approximately 2–3 mm, the partial backstitch up to 7mm, and other stitches (zigzag) 2–3 mm long. The techniques identified with the help of medieval finds from Estonian cities are similar to those found in other European cities. We cannot tell from the fragments whether they have been made at home or by professional tailors.
Sewing by hand should be promoted and used in the production not only of copies of artefacts, but also of contemporary items too. This would encourage us to value handicraft and good materials and to make items that have an emotional value.

Abstract In single needle lockstitch sewing machines, the needle thread consumption of 10 normal stitches for a fabric with a particular number of layers at a particular stitches per unit length is manually measured kept as a reference value. If the value of needle thread consumed per stitch is very small, the length of thread consumed per 10 stitches is used as a comparing value. The actual thread consumed for every 10 stitches is measured online by a rotary optical encoder sensor by converting the angular movement into the linear movement of the thread and continually compared with the reference value. If the online measured length is more or less a buzzer sounds to indicate the variation. The counting of every stitch formed is undertaken by a proximity sensor by sensing the protrusion in the hand wheel of the machine, which rotates once for every rotation.

Machines of chainstitches 104 create imitation of hand stitches 209 from one material side. Every hand stitch is formed from two threads, therefore the seams are more accented and very short length pick stitches are larger than created seams from real hand stitches 209. The length of the hand stitches is determined by the distance between a sewing needle and a hook needle of the machine. To create different length hand stitches a gauge set of the machine has to be changed. Because of different appearance of the stitches on top and bottom fabric surfaces the machines are used for top stitching of seams which are seen on a ready garment from one side only. In men suit manufacturing there are: top stitching of a jacket's lining, top stitching on pockets, fronts, etc. of jackets, vests, trousers. There are also available chainstitch 104 machines which create different variations of the hand stitches: double row hand stitches, parallel hand stitches, angular hand stitches. Comparing with the machines of real hand stitches 209, the machines of chainstitches 104 are much lower priced and have much higher productivity .

Full textAbstract:
A sensor system that inspects a garment as it is being sewn has the potential to eliminate much of the cost associated with inspection and to improve product quality. An economically feasible on-line stitch quality monitoring system is under development that utilizes commercially-available, low-cost piezoelectric sensors and a PC-based Linux data acquisition system. The sensors respond to the vibration caused by the thread motion and output a corresponding waveform used to study and model the formation of single stitches. As a result, the presence of periodic occurrences can be identified and attributed to proper stitch formation. Conversely, the absence of such events can be utilized to signal the presence of single stitch defects and diagnose their causes. Finally, high speed image analysis of the sewing threads has verified conclusions drawn from the output signals of the piezoelectric sensors and contributed to a better understanding of the dynamics involved in high speed sewing.

Airbags are subjected to strict quality control in order to ensure passengers safety. The quality of fabric and sewing thread influences the final product and therefore, sewing defects must be early and accurately detected, in order to remove the item from production. Airbag seams assembly can take various forms, using linear and circle primitives, with threads of different colors and length densities, creating lockstitch or double threads chainstitch. The paper presents a framework for the automatic detection of defects occurring during the airbag sewing stage. Types of defects as skipped stitch, missed stitch, or superimposed seam for lockstitch and two threads chainstitch are detected and marked. Using image processing methods, the proposed framework follows the seams path and determines if a color pattern of the considered stitches is valid.

This study aims to estimate the impact of sewing thread patterns on changes in the resistance of conductive yarns coated with silver paste. Firstly, the structure of the conductive yarns was examined, and various variations in the length and angle of individual sewing stitches were observed and analyzed through experiments. The results revealed that as the length of an individual stitch decreased, the width of the conductive yarn increased. Additionally, variations in the stitch angle resulted in different resistance values in the conductive yarn. These findings provide essential information for optimizing sewing patterns and designing components. Secondly, the comparison between models using multiple linear regression analysis and sewing neural networks was included to show optimized resistance prediction. The multiple linear regression analysis indicated that the stitch length and angle were significant variables affecting the resistance of the conductive thread. The artificial neural network model results can be valuable for optimizing sewing patterns and controlling resistance in various applications that utilize conductive thread. In addition, understanding the resistance variation in conductive thread according to sewing patterns and using optimized models to enhance component performance provides opportunities for innovation and progress. This research is necessary for the textile industry and materials engineering fields and holds high potential for practical applications in industrial settings.

The purpose of this study was to determine the use of basic sewing books to improve the ability to sew basting stitches for students with autisms. The method used in this classroom action research is a demonstration learning method. The subjects of this study were 3 students with autisms at Sekolah Luar Biasa Negeri Sukanagara. The use of basic sewing books showed an increase in the ability to sew on a bast stitch in all students. In the third cycle, each student gets a score that exceeds the minimum completeness criteria that have been set, which is 81. This happened because the basic sewing books used were easy to understand and follow by students. This study demonstrates that the use of an easy-to-understand basic sewing book will accelerate students' understanding. In addition, a good basic sewing book will also make it easier for teachers to guide students, especially for students with autisms.

This study was designed to explore the seam performance with special focus on seam strength and efficiency for commercially obtainable different types of denim fabrics. Technically seam performance is portrayed by strength of seam, elongation of seam and efficiency of the seam. Seam performance can contribute as an imperative factor in determining the durability of a garment. Different combinations of denim fabrics were used for seam strength and efficiency analysis together with four different types of commonly used stitch structures along with three types of sewing threads like 40, 60, and 80 tex. Seam strength and efficiency for different denim fabrics were changed consecutively with varying types of stitches combined with increasing stitch density. More specifically, supreme seam performance was observed at light indigo 170 g/m2 (GSM) 100% cotton twill denim fabric for overlock stitch structure alongside higher stitches rather than others. Characteristically the seam line which contains more stitch density encompassed in different denim fabrics demonstrates more seam eminence.

Abstract In this paper, a novel classification method of assessing garment sewing stitch based on amended bi-dimensional empirical mode decomposition (ABEMD) has been introduced. Two parameters that characterise garment sewing stitch, average area and standard deviation, have been defined based on the grey value of pixels. Experimental results showed that when the window size is 512×128 pixels with regard to average area, the threshold can be decided as 6.00, 5.50, 5.30 and 4.00 for five different grades , respectively. Meanwhile, with regard to standard deviation, the threshold can be decided as 48.00, 40.00, 30.00 and 20.00, respectively. It is demonstrated that the parameters are effective in discriminating sewing stitch images in terms of the grades when used as inputs for the ABEMD. The performance of the algorithm on different garment status is significantly reliable.

The objective of present research is to analyze the impact of knitted fabric structures, sewing thread types and stitch types on seam strength, seam slippage, seam pucker, and seam efficiency on quality of garments. Seams are basic necessities in the manufacturing of garments. In general, seam performance has an enormous impact on the garment quality. Seam and stitch types have a positive effect on the quality and appearance of garments. Seams of the garment must be durable and smooth. Stitch and seam types and stitch and seam parameters should be chosen according to the garments and fabrics (single jersey, rib, and interlock) Seam production of a garment also depends on structural and mechanical properties of the fabric such as strength, extensibility, protection, durability, appearance, and efficiency of the seams. The performance of seams also depends on the sewing conditions like size of needle, sewing thread tension, stitches per inch and lastly on the proper working and maintenance of the stitching machine. An experimental design was employed for the analysis which includes two types of sewing thread and four classes of stitch. The results exposed that differences existed between the two dissimilar threads in relation with seam quality Polyester-wrapped threads with a polyester filament core thread shows better seam strength, seam slippage, seam puckering and seam efficiency. It is noted that seam efficiency increases with seam angle and sewing needle type. It has been found that small ball point needle type exhibits poor seam efficiency but an improvement in efficiency has been observed with Medium ball point needle type and conical point needle type for all three knitted fabrics.

Members of a patent pool agree to use a set of patents as if they were jointly owned by all members and license them as a package to other firms. This article uses the example of the first patent pool in U.S. history, the Sewing Machine Combination (1856–1877) to perform the first empirical test of the effects of a patent pool on innovation. Contrary to theoretical predictions, the sewing machine pool appears to have discouraged patenting and innovation, in particular for the members of the pool. Data on stitches per minute, an objectively quantifiable measure of innovation, confirm these findings.

With their properties, upholstery covering materials significantly influence the quality of upholstered products. These materials form the surface layer of upholstered furniture; any damage to this material is immediately visible to the user. We consider the stitches connecting the covering fabrics to be one of the critical points of the upholstered surface, therefore they must have the required strength. Faux leather is one of the most used upholstery materials. The main aim of the paper is to determine the effect of upholstery faux leather, stitch length, point needle, and needle size on the strength of the stitches and the seam efficiency. The results of the experiment proved the suitability of using a sewing needle LR for joining covering materials such as faux leathers. The highest force to seam a rupture in the joints was achieved in the direction of the warp yarns of the underlying layer of PU (Polyurethane) faux leather with a stitch length of 4 mm and needle type LR/90. The highest seam efficiency was achieved with seams in the direction of the weft yarns of the PVC (Polyvinyl chloride) faux leather underlying layer with a stitch length of 4 mm and needle type LR/90. If the underlying layer of faux leather is a fabric with canvas binding, a higher seam efficiency of joints is assumed.

Full textAbstract:
Defective stitch inspection is an essential part of garment manufacturing quality assurance. Traditional mechanical defect detection systems are effective, but they are usually customized with handcrafted features that must be operated by a human. Deep learning approaches have recently demonstrated exceptional performance in a wide range of computer vision applications. The requirement for precise detail evaluation, combined with the small size of the patterns, undoubtedly increases the difficulty of identification. Therefore, image segmentation (semantic segmentation) was employed for this task. It is identified as a vital research topic in the field of computer vision, being indispensable in a wide range of real-world applications. Semantic segmentation is a method of labeling each pixel in an image. This is in direct contrast to classification, which assigns a single label to the entire image. And multiple objects of the same class are defined as a single entity. DeepLabV3+ architecture, with encoder-decoder architecture, is the proposed technique. EfficientNet models (B0-B2) were applied as encoders for experimental processes. The encoder is utilized to encode feature maps from the input image. The encoder's significant information is used by the decoder for upsampling and reconstruction of output. Finally, the best model is DeeplabV3+ with EfficientNetB1 which can classify segmented defective sewing stitches with superior performance (MeanIoU: 94.14%).

One of the problems that related to quality and often occurs in the sewing process at CV Batara Apparel is that there are frequent thread break problems. Termination problems that occur are caused by an error during the thread installation process that does not pass through the needle bar hole and the thread is directly passed through the needle. This results in defects in stitches such as broken stitches. In order to solve the thread break problem caused by an error during the thread installation process that does not pass through the needle bar hole, it can be overcome by implementing SOP (Standard Operational Procedure) on proper and correct machine usage procedures, briefing supervisors with the production manager so that the problems occurs when production takes place can be handled properly. In addition, the implementation of regular maintenance schedules can also solve the thread break problems that occur.

Abstract This work deals with the evaluation of sewing thread consumption in jeans and classic pants clothing. Six different input parameters are chosen and used for investigation. To objectively evaluate their contributions, a Taguchi design analysis was applied. Based on the comparison between each input parameter effect, this experimental analysis helped us to classify the overall tested factors. Indeed, our findings show that the sewing yarn affects widely the thread consumption during stitching of the pant. In spite of their non negligible impact, the number of stitches per cm and the needle type can be considered as influential input factors on thread consumption. In our experimental design the other tested factors were kept constant.

Owing to a high amount of stress, seam failure in workwear fabrics makes the fabric unsuitable although the fabric strength is high. It is therefore important to predict the seam strength to ascertain the performance of the garments during use and determine the required thread strength to match the required seam strength. An assembly is composed of a sewing thread and a fabric. The thread forming the seam undergoes several stresses during its passage from the sewing machine to the formation of the loop and when wearing the garment: these are mechanical stresses. Therefore, it is necessary to evaluate the strength of the seam. But, in the bibliography, most researchers have studied the strength of the seam concerning a single type of stitch. This work aimed to examine the seam's strength from the resistance to the loop of the thread for all types of stitches. In all of the earlier predictive equations, seam strength is predicted from thread loop strength with some multiplicative factors. The thread loop strength is measured without considering the stitch type. During the sewing process, threads loop differently from one stitch to another, therefore, the standard thread loop strength becomes unfit to predict the seam strength. In this paper, the effects of loop thread length and configuration are studied on thread loop strength and seam strength. The seam strengths predicted from the loop strength before and after considering the new loop configurations and the real seam strength are compared. So, new clamps for loop strength are configured and carried out. It is observed that there is a closer match between experimental and predicted seam strength with new loop configurations. The loop configuration has a significant effect on the thread loop strength and improves the accuracy of seam-strength prediction.

There was a phenomenon that occurred in garment companies, namely the existence of defect products in the production process. In the sewing process, defects occurred with an average percentage of 6,67% in the first three months of early 2019. This 6,67% was a percentage of disability that exceeded the company percentage limit of 5%, thus disrupting the production process. The primary purposed of analyzing the factors of product defects was to find out the causes and solutions to the company. The Fault Tree Analysis method was used to find out the root caused of product defects. Three main problems caused product defects, namely 1) untidy stitches, 2) stitches that exceeded the specified size, and 3) straightened stitches. By using the Failure Mode Effect Analysis method, the three problems were caused by human error and the absence of a Standard Operating Procedure in the production process. As a solution to problems in the company, the Risk Priority Number value was used. From this study the result obtained 1 Risk Priority Number value is the proposed improvement.

Various sewing activities are an appropriate step in improving children's fine motor skills, because they are used to express themselves. To produce interesting stitches really helps develop a child's imagination in improving their fine motor skills. PAUD Al-Quran Az-Zahra Banyurip Alit Pekalongan City on fine motor activities failed in various sewing materials, this can be seen from the work of children with a total of 20 children who got good grades only 5 children, only 4 children, and less than 11 children. The problem is the lack of physical fine motor skills of children in various sewing activities. This is because the media used is less varied so that children feel bored. So we need an active learning method using various media. The aim of this research is to improve children's fine motor skills in sewing with various media. The benefits are expected to contribute to the development of science. In carrying out the improvement of learning through two cycles. The results of observations and research in the second cycle increased more than the previous cycle. The results of the previous comparison had a success rate of only 45%, the first cycle was 65%, the second cycle reached a 95% success rate. So it can be concluded that sewing activities have a positive impact on fine motor development and can improve children's ability to sew with various media.

Während ein Sprechakt durch seine Äußerung agiert, handeln Nähstiche, indem sie sichtbare und oft feierliche Verbindungen zwischen Materialien schaffen, um Autorität zu steigern, zu verschönern, zu behaupten und zu schichten – oder um einen Gegenstand in Textilien zu hüllen, als handelte es sich um eine Reliquie. </br></br>This essay considers medieval sewing in light of Austin's speechact theory. Analysing manuscripts, relics, indulgences, and even a bishop's mitre, the article argues that stitching was a way to enact, or intensify, the ritual purpose of objects, whether that was ceremonial, devotional, or authoritative. Whereas a speech act functions by its utterance, stitches act by forming visible and often ceremonious attachments between materials in order to aggrandise, embellish, assert and layer author ity, or swathe an object in textiles as if it were a relic.

Owing to spandex silks are very thin and transparent, it is very hard to spot the broken warp without alarm during sewing or weaving. Therefore, the key to solve the problem is to shutdown and alarm timely when warps break. The ways and principles of common warp stop are analyzed in this paper, a new type of warp stop motions is developed for textile purposes to avoid inconveniences and malfunctions of the traditional method. Alarming rate and stability can be improved effectively by the compact and lightweight design of drop stitches, controlling system with converting functions as well as the modified testing, protection, reset.

To determine the effect of nanosized organosilicon softeners on the indices of the technological properties of a knitted fabric, to assess the possibility of their improvement through the use of innovative finishing processing. Theoretical and experimental studies are based on the basic principles of textile materials science. In experimental studies, standardized methods and techniques were used, which are reflected in the laboratory by providing softening treatment for knitted fabrics. The sewing process was performed on a Juki DLL-8100e industrial sewing machine. The stitch frequency of the stitches was determined by the registration method. It is determined that the use of nanosized organosilicon softeners significantly affects the performance of the technological properties of a knitted fabric. It was found that the Kolosil nanosized organosilicon softener, which was used by the selection method at a concentration of 4% of the processed material, has a maximum effect on the total deformation and increases the proportion of the slowly inverse deformation component. It is shown that the use of softeners has a positive effect on the stability of the linear dimensions of a knitted fabric. It is proved that the final processing of knitted fabric with innovative nanosized organosilicon softeners can be considered a factor in reducing the technological complexity of garments. The scientific hypothesis has been experimentally confirmed in the use of nanosized organosilicon softeners to improve the indicators of the technological properties of a knitted fabric. It is shown that treatment with nanoscale softeners causes changes in the structure of fibers at the micro level, which are of paramount importance for the formation of technological properties of a knitted fabric. The research results can be used in the development of new materials with improved properties, in the design of clothing parts and in sewing knitted fabrics.

Full textAbstract:
Seam quality in terms of appearance and strength were investigated for very light weight fabrics (weight less than 80 g m-1;. Seams were constructed with different sewing parameters, which included types of thread, stitch densities and needle size. Before constructing the seam for appearance and strength evaluation the mechanical properties of all fabrics were determined. The mechanical properties of 48 fabrics were determined using the Kawabata Evaluation System (KES-F), the Fabric Assurance Simple Test (FAST) and an lnstron Tensile Tester. Evaluation of seam quality was performed with respect to all the sewing parameters and the seams were ranked accordingly. The same evaluation ranking for seam appearance and strength was used for further analysis using Structural Equation Modelling (SEM) under AMOS. SEM was used to establish the relationship between seam quality with respect to appearance and strength, and fabric mechanical properties. SEM was adopted to perform confirmative analysis to identify the fabrics mechanical properties that influence seam quality. From the experimental work, it was established that seams constructed with I 00 % spun polyester thread with a ticket number of 75 gave the best ranking in terms of seam strength. This thread performed at optimum values when used with 6.5 stitches per centimetre (spcm) with a Metric needle size (Nm) of 90. For seam appearance, I 00 % spun polyester with a ticket number of 120 and Metric needle size of 80 gave the best ranking. SEM established that extensibility and shear were the main fabric mechanical properties that determine seam quality of very light weight fabrics.

Full textAbstract:
Seam strength is critical in achieving the proper and adequate quality seam, which eventually determines the overall quality of any garment. The target of this research was to investigate exactly how different stitch density affected seam strength for different stitch types. Commercially available, 100% cotton plain weave structured woven fabric with mass per unit area of 270 g/m2 was used in this analysis. Two different stitch types, such as lock stitch (ISO#301) and chain stitch (ISO#401), along with four stitch densities like 8, 10, 12 and 14 per inch were utilized. The seam strength of the prepared samples was determined using a tensile strength tester followed by the ASTM D1683 standard procedure. The impact of independent variables on superimposed seam strength was statistically analyzed using a regression correlation with the help of SPSS software to construct a regression equation to predict seam strength before the manufacturing process. The study found a non-linear relationship between seam strength and stitch density. When the stitch density is too low, the seam strength is shown low as well, because the cloth cannot be held under tensile load. In a very compact woven fabric, structural jamming or intrinsic puckering occurs if it is too high. As a result, the best stitch density should be chosen to achieve the best seam strength. This study will help the manufacturers choose a suitable SPI for lock and chain stitches from polynomial regression equations before the sewing production of cotton woven fabric, which was not predicted by any researcher before. Therefore, the optimum stitch density can be chosen using regression equations to get the best result for seam strength.

In this research, intestinal anastomosis was compared in hand and automatic suturing. This work is based on two different experiments: The first one is the tensile test with the aim of finding the maximum breaking strength with the elongation rate of 5[Formula: see text]mm/min; and the second one is the fatigue test with a frequency of 0.2[Formula: see text]Hz and the amplitude of 16, 24 and 32[Formula: see text]mm of stretch in each phase to discover the total number of cycles to failure. For this purpose, 42 fresh bovine intestines were used; 21 specimens for the tensile and 21 for the fatigue test. These two tests were compared by two hand sewing techniques: simple continuous and ford interlocking stitches, and one automatic technique, i.e., the lock stitches. Seven samples were examined for each particular technique. The results of the tensile test indicated that the breaking strength of automatic sutured specimens is significantly greater than those of hand sutured specimens ([Formula: see text]). That might be due to the regularity, as the suturing lines by machines are more regular than suturing by hand. In addition, results showed that automatic sutured specimens failed in greater number of cycles than hand sutured specimens in the fatigue test ([Formula: see text]).

Facing an era of increasingly fierce competition, a person is required to have a high entrepreneurial spirit so that he can run a business that he lives well. Thus we must be able to see market opportunities and desires in terms of needs and selling points that we will offer to consumers. Entrepreneurs in sewing services are still promising. Even though now there are a lot of apparel production, stitching services are still needed by consumers. Because there are some risks in purchasing apparel that are usually accepted by buyers. Not all clothes fit to be worn by consumers. Especially for people who have different body postures from the standards of people in general, such as too small or too fat. Besides that, there are certain clothes models and materials that are more comfortable when used from ordinary stitches, rather than in the form of apparel manufactured by the factory. For example, traditional clothing, brocade fabrics, suits, kebaya, woven fabrics and others. In connection with this, it is felt necessary to provide training to improve the skills of clothing tailors to be able to produce clothes that are in accordance with market desires efficiently and effectively. Besides improving skills in spraying and embroidering in order to have the ability to compete in terms of quality, models, variations in motifs and the color combination of clothing produced, so as to create and have a lot of marketing networks. The need for training that enables tailor clothing to calculate total sales revenue and total costs so that they are able to know how much profit is obtained per piece of clothing. It is hoped that after the mentoring, the partners will be more knowledgeable, able to apply this knowledge in their daily work and transmit this knowledge to other dressmakers. Thus, all dressmakers will develop more, become more economically independent, increase in income, tailor clothes become more productive and be more optimistic in entrepreneurship.Write abstracts in English only if the contents are in English or English and Indonesian also fill in Indonesian with a maximum of 200 words.

This paper reports on two generative systems that work in the domain of textiles: the Hoopla system that generates patterns for embroidery samplers, and the Foundry system that creates foundation paper piecing patterns for quilts. Generated patterns are enacted and interpreted by the human who stitches the final product, following a long and laborious, yet entertaining and leisurely, process of stitching and sewing. The blending of digital and physical spaces, the tension between machine and human authorship, and the juxtaposition of stereotypically masculine computing with highly feminine textile crafts, leads to the opportunity for new kinds of tools, experiences, and artworks. This paper argues for the values of textiles as a domain for generative methods research, and discusses generalizable research problems that are highlighted through operating in this new domain.

Full textAbstract:
The main purpose of this study is to predict and develop a model for forecasting the Seam Strength (SS) of denim garments with respect to the thread linear density (tex) and Stitches Per Inch (SPI) by using a Fuzzy Logic Expert System (FLES). The seam strength is an important factor for the serviceability of any garments. As seams bound the fabric pieces together in a garment, the seams must have sufficient strength to execute this property even in the unexpected severe conditions where the garments are subjected to loads or any additional internal or external forces. Sewing thread linear density and number of stitches in a unit length of the seam are the two of the most important factors that affect the seam strength of any garments. But the relationship among these two specific variables and the seam strength is complex and non-linear. As a result, a fuzzy logic based model has been developed to demonstrate the relationship among these parameters and the developed model has been validated by the experimental trial. The coefficient of determination ( R2) was found to be 0.98. The mean relative error also lies withing acceptable limit. The results have suggested a very good performance of the model in the case of the prediction of the seam strength of the denim garments.
