Abstract This research explored the potential for ink-jet printing to replicate the coloration and finishing techniques of traditional denim fabric and standardized the reproduction and evaluation procedure. Although denim fabric is widely consumed and very popular, one drawback to denim is that the finishing and manufacturing processes are energy and water intensive and can cause environmental hazards as well as generation of pollution through water waste, particularly at the finishing stage. Textile ink-jet printing has the potential to replicate some of the coloration and finishing techniques of traditional denim fabric without negative environmental impacts. A two-phase research project was conducted. In Phase I (P1), an optimal standard production workflow for digital denim reproduction (including color and finishing effects) was established, and six different denim samples were reproduced based on the workflow. In Phase II, an expert visual assessment protocol was developed to evaluate the acceptance of the replicated digital denim. Twelve ink-jet printing, color science, and denim industry experts finished the assessment.

Full textAbstract:
Denim fabric is one of the most popular casual wear fabrics worldwide. The performance characteristics of denim fabrics have been improved by using functional fibers and elastane to make them comfortable to wear. Elastane fibers with high elasticity are used extensively in denim fabric production. Elastane fibers are generally used as the core part of the core-spun yarns as weft yarns. Besides elastane fibers; polyester and polyester derivatives are commonly used. This study examines the effects of filament fineness and yarn count on denim fabric performance. Textured polyester filaments with medium, fine and micro linear densities were used as the core part of the core-spun yarn and cotton fiber was used as sheath material. Yarn samples manufactured with the same production parameters at different yarn count were used as weft yarns of denim fabrics. Denim fabrics were produced with the same fabric cover factor to eliminate yarn count difference effects. Tensile, static tearing and dynamic tearing properties of denim fabrics were determined. To evaluate the effects of core part, 100 % cotton denim fabric was manufactured and tested. Statistical analysis was performed to analyze the significance of filament fineness and yarn count ratio. Results showed that there was a significant effect of filament fineness on tensile, static tearing and dynamic tearing properties of denim fabrics. In addition, it was found that yarn count had no significance effect on static tearing properties of denim fabrics.

Denim jeans need to be wet-processed in order to create a comfortable feel and a versatile look in the end product. The use of Ozone to finish denim jeans offers environmental and economic benefits by reducing rinse periods, water use, and energy consumption. Ozone is a specialized oxidant with a strong oxidation potential and can decolorize textile effluents, and it has a particular affinity for indigo. This paper will demonstrate why Ozone-based denim wash should be recognized as sustainable in different aspects of denim washing. The study observed that denim fabric finishing with Ozone particles has reduced garments processing time and requires less water and chemicals than the Conventional finishing method. Moreover, because of the low use of chemicals and water, ozone-based finishing produces a minimal amount of wastewater which eventually has less impact on the ETP as well as less effect on the environment than the traditional denim washing method. Also, it gives two times more production than conventional. With an in-depth evaluation of different washing points, this paper has concluded that Ozone-based wash is a promising finishing treatment for denim products.

Carbon footprint (CFP) reflects the greenhouse gases (GHGs) produced by human activities or products throughout the life cycle, which is an important tool for assessing and managing greenhouse gas pollution. The reduction of Carbon footprint is an important topic today, and each of us needs to minimize our CFP in order to protect our planet. In this paper, the basic cotton denim jackets was played an research object roles to exploring the impact on the environment during the process of producing cotton denim jackets. Which based on the theory of industrial carbon footprint and combing with the production process chain of denim jackets, setting the accounting boundaries and functional units, the denim jacket can be divided into cutting, sewing, and finishing the three links in industrial production of carbon footprint. With the calculation and analyzation industrial carbon footprint of the denim jacket. The results show that the carbon footprint of denim jackets exceeds 1000 kg CO2 during the cycle from cutting to sewing and finishing. The largest carbon footprint is generated in the sewing process, which are about twice as high as the cutting process. The carbon footprint emissions of each piece of denim jacket is 1.75 kg CO2. Therefore, optimizing the production line in the sewing process, adopting high energy-efficient processing equipment and clean energy can better reduce the industrial carbon footprint of denim clothing. It also provided reference and basis for the supervision and evaluation of carbon emission by clothing manufacturers

Kapok is a hollow fiber with a 90% hollow degree. Compared with cotton fiber, kapok fiber has excellent performances, such as good hygroscopicity, and a good warmth retention property. In this work, desized indigo kapok/cotton denim fabrics were bleached in different ways: Laser, cellulose enzyme, sodium hypochlorite, potassium permanganate and hydrogen peroxide. After bleaching, the K/S values, tensile strength, air permeability, thickness, color fastness to rubbing and the crease recovery angle of denim fabrics were measured through the spectrophotometer, tensile strength tester, air permeability tester, thickness tester, rubbing fastness tester and fabric crease elasticity tester, respectively. The surfaces of fabrics and fibers were observed by scanning electron microscopy (SEM). Results show that the kapok/cotton fabrics were color-faded after five kinds of bleaching, the K/S values of denim with laser bleaching was declined dramatically, while there was a little change in the permeability. The tensile strength and the weight of the fabrics were decreased, and cloth which was bleached with potassium permanganate was most affected. The color fastness to rubbing and the crease recovery angle of denim fabrics with laser treatment is most suitable for industrial production. In general, laser bleaching is the better way to fade the kapok/cotton denim fabrics. Meanwhile, after five kinds of bleaching, the physical properties of kapok/cotton denim fabrics were similar to those of cotton denim fabric, which indicates that kapok/cotton denim fabric is suitable for the existing industrial bleaching technology.

Denim fabrics which are highly demanded products among the world have high consumption rate in the textile market. Those fabrics may be utilized for different purposes. Durability, elasticity, wearing resistance are the important expected properties from denim fabrics. Tearing resistance of denim fabrics in use is another parameter that should be considered. This study includes the investigation of tearing properties of denim fabrics produced from single core (Polyethylene terephthalate/Polytrimethylene terephthalate (PET/PTT) bicomponent filament and elastane) and dual core (PET/PTT+elastane feeding simultaneously) spun yarns utilized as weft yarns. Denim fabrics with different layout of these weft yarns with uncovered PET/PTT bicomponent filament were produced in order to compare the tearing strength properties in warp and weft wise. Results revealed that highest tearing strength of weft wise was obtained from denim fabrics at 2F:2CY layout where two uncovered PET/PTT bicomponent filament and two PET/PTT bicomponent filament+elastane dual core-spun yarn were used consecutively in the layouts. The lowest tearing strength was found among the denim fabrics at 1F:6CY layout where one uncovered PET/PTT bicomponent filament and six PET/PTT bicomponent filament+elastane dual core-spun yarns were used consecutively in the layouts. According to statistical evaluation; Weft yarn type, weft yarn layout and their interaction in the fabric were found to having significant effects on tearing strength for both warp and weft direction of denim fabric at significance level of 0.05.

There is a tendency to use different fibers from cotton to improve the physical properties of conventional denim fabrics, add functional properties, and follow trends and fashion. Warp and weft yarns can be produced with 100% cotton or composed of different fibers optionally for denim fabric. In this study, a piece of detailed information was given about the fibers used for denim fabrics in recent years, and the effects of the fibers were evaluated. In the results of the review, the nature of the fiber and antibacterial property is the most prominent feature nowadays for cellulosic fibers. It is quite advantageous antibacterial fibers also have additional functional properties without further processing. Wool and silk are widely used in conventional textile. They are especially preferred when thermal comfort is required in denim fabric production. Synthetic fibers are indispensable for denim especially when high performance is needed. Also, it is important for the wearer to feel comfortable, so new generations of synthetic fibers that provide high comfort are widely used. Elastane is a characteristic fiber of denim fabric and always a new type of elastane fiber is produced. Besides elastane used in flexible denim fabrics, elastomultiester fibers are popular now. These fibers do not contain elastane but they provide excellent elasticity and recovery for the fabric.

Full textAbstract:
One of the most distinctive features of denim is that the warp yarn is dyed with indigo dye and the weft yarns are not dyed, i.e. white. Although warp yarns dyed with indigo dye are woven with different woven fabric weaves, classical denim fabrics weave are produced with 3/1 Z twill weave. The search for new products in denim has led businesses to produce denim-looking knitted fabrics. Denim-looking knitted garments are subjected to industrial washing at the production phase and repetitive household washing processes in daily life. Repeated washing and drying processes cause changes that can affect user satisfaction in terms of losing the colour of the fabric. Therefore, in this study, the colour values of knitted denim fabrics produced as an alternative to denim fabrics manufactured by traditional methods after various industrial (rinse, enzyme and stone washing) and home washes (5, 10, 20 times) were examined. For this, the CIELab colour system was taken as the basis for colour analysis on a spectrophotometer device. As a result of the washing processes performed on each fabric sample (household washing and rinse, enzyme, stone washing applications), it was observed that there were differences in colour values depending on the fibre type, loop yarn length, fabric construction and washing process.

The washing and the special treatments (enzyme and/or pumice washing for aged look) on denim garments are the important parameters influencing cloth shade, color fastness and the fabric mechanical properties. The most commonly used indigo dyestuff for dyeing denim fabrics is the process of producing waste, consuming excess energy and wate. In this study, we made an attempt to reduce the environmental damage of denim dyeing processes by using nanocoating method. Indigo and reactive dyed denim fabrics were purchased from GAP Textile and used for obtaining nanofilm coated denim fabrics. Optifix E50 is used for cationic layers and Tanapur EP3027 is used for anionic layers. In the deposition process, denim fabrics were deposited with 10 multilayer films by using a padding machine for padding process and a modified open-width washing machine for continuous process. Scanning electron microscopy measurements were used to verify the presence of the deposited nanolayers. Colour fastness to washing, Colourfastness to Perspiration, Colourfastness to Water, Colourfastness to crocking and tensile strength were performed to examine the LbL process effect on the denim fabric properties. This study shows that continuous nanofilm deposition process can be used for enhancing color fastness properties of especially reactive dyed denimfabrics

Denim fabrics became a preferred product by many people, because of especially being a symbol of comfort. In thisstudy, the aesthetic and physical design of denim fabrics were carried out. It was aimed to compare the surface designsand structural parameters of denim fabrics obtained by weaving and laser technologies. Besides the design steps ofweaving and laser technologies were explained and compared. Twelve denim fabrics having different surface designswere obtained with the intersection of indigo dyed warp and non-dyed weft yarns based on the theme of “contrast” byusing derivatives of twill weave. Besides, these surface patterns were applied to classical denim fabrics by lasertechnology. The surface properties of denim fabrics produced by weaving technology were different for each surfacedesigns because of different floatings. However, weaving is a time-consuming method and the design steps are morecomplicated.

Chemical washing of fresh-assembled denim garment is a fundamental finishing process in textile and ready-made garment industries and has the largest effect on the physico-mechanical properties on finished denim garment. In this study, modification of denim trousers by washing using pumice stone mixed with bleaching powder was investigated. The fresh-assembled denim trousers, twill 3/1 weave and composition 100% cotton, have been processed by stone-bleach treatment using parameters namely concentration of bleaching powder (5.0 to 15.0 g/L) (owl) with 30% pumice stone (owg) at washing temperature 40oC and at pH 10.5 for treatment time 20 min in the fiber to liquor ratio of 1:10 in an industrial sample washing machine. In order to evaluate the influence of these washing parameters on the properties of denim trouser like tensile strength, fabric weight, color change, stiffness and water absorption, has been determined. Fabric surface was also examined by scanning electron microscope (SEM) and fluorescence microscope (FM). It can be concluded that the washing parameters had influenced on the physico-mechanical properties of finished denim garment. Especially stone-bleach treatment helped to get the specific color fading effect and softness of denim garment, which gave a new-look appearance and good wear performance to the fabric distinctly. The results indicate that for producing durable and sustainable denim garment the optimized washing condition for the best value is 10.0 g/L bleaching powder mixed with 30% pumice stone in the stone-bleach treatment.

Denim is one important clothing product recently in the market. However, the original solid blue colour is not attractive to the consumers and hence many manufacturers are trying to remove part of the blue colour from the denim fabric surface. This fading effect could impart fade-look or worn out effect in the final products which made it becomes popular to the consumers. There are different methods to achieve the colour fading effect in which enzyme washing is one of the simplest methods to be used in the industry. Although the enzyme washing is a good method for colour fading of denim, the process involves the use of chemical as well as temperature which may introduce certain degree of damage in denim fabric. Thus, this paper will investigate the effect of enzyme washing on the tensile property of denim fabric under different treatment duration.

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.

Full textAbstract:
Fiberboards from scrap denim were fabricated using two different resins, melamine urea formaldehyde (MUF) and polymeric methylene diphenyl diisocyanate (pMDI). Resin content and MUF-pMDI weight ratio were studied. Physical and mechanical tests determined the modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB), thickness swell (TS), and water absorption (WA). The resin content had significant impact on all properties. The MOE and IB were affected by the MUF-pMDI ratio. With 17 wt% more pMDI resin portion in the core layer of the denim boards, the IB for the denim fiberboard with a resin content of 15% was enhanced by 306%, while by 205% for the resin content of 25%. The increase in pMDI portion in the core layer of the boards improved both TS and WA of the scrap denim fiberboard. Effective bulk modulus elastography (EBME) was used to measure the acoustic reflection for the estimation of the strength properties of the denim fiberboard. The modulus results from EBME were correlated to the MOR, MOE, and IB of the denim fiberboard. A high correlation was found between the modulus from EBME and IB (R2 > 0.98). EBME can be a great technique to evaluate the bulk modulus distribution of the composites.

Full textAbstract:
Cotton is one of the most-used natural fibres in the world due to its relative comfort and strength compared with other natural fibres. However, the processing of cotton for manufacturing products consumes a lot of water, while harvesting cotton uses significant amounts of pesticides. One solution to this ecological problem is to recycle cotton waste. This study investigated the effect of blending virgin cotton with two categories of denim cotton waste—sourced during the winding and dyeing processes and used in various ratios—on the quality of blended denim cotton. The study was realised in collaboration with a large manufacturer of denim fabrics in Tunisia and a producer of preparation machines in Italy and aimed to use an adequate process to recycle cotton yarn waste and to obtain fibres with acceptable quality. The research aimed at providing a solution to the great demand for denim with the use of reclaimed fabric, which accompanies the increased need for denim with a fancy effect and the obligation of denim producers to follow environmental standards required by many brands The results show that it is possible to obtain a good quality of blend yarn using virgin cotton and cotton waste even when the waste content exceeds 50%. These results are significant for textile mills. Reprocessing fibres from denim colour-processing waste has a lot of advantages, including reductions in wastewater treatment and the consumption of energy, chemicals and water. In addition, the process eliminates the need for the dyeing and finishing processes of these coloured fibres.

Full textAbstract:
The prime intention of this study is to develop and validate the efficiency of a fuzzy logic model to predict the tensile strength of bleach washed denim garments. Denim washing is nowadays a widely used technology to give a worn-out appearance to denim garments and thus add esthetic to that garments’ appearance and outlook. In the case of regular overall fading of denim, bleach washing is very popular. At the same time, it is also a matter of concern that the process optimization of bleach washing is critical as bleaching agents have an adverse effect on the fabrics. Among others, bleach concentration, time, and temperature are the primary process parameters in bleach washing, which directly impact the final strength of the treated denim garments. Though their relationship is nonlinear, a fuzzy expert-based system has been constructed to model and illustrate the complex relationship among bleach concentration, time, and temperature in the input side, whereas tensile strength is the output. Strength is the most critical parameter of the final denim product, as it dominates the serviceability of that garments. Therefore, predicting the tensile strength without the trial-and-error method, which is being practiced now, can be a blessing for industrial practitioners. With the help of a laboratory trial, the developed model has been evaluated, and it has been found that the mean relative error was 2.82 and 3.92 for warp and weft direction tensile strength, respectively. On the other hand, the comparison exhibited a coefficient of determination ( R2) of 0.99 for both warp and weft direction tensile strengths. The authors found that the performance of the developed model is satisfactory enough to predict the tensile strength of the bleach washed denim garments.

Full textAbstract:
This research aims to determine the time limit needed and the environmental conditions that provide the highest success rate in identifying dried blood samples on the fabric of stretch denim, ramie denim, black coated denim, and dry denim jeans using the elution absorption method. Also, to evaluate the effect of the fabric fabric, environmental condition, time, and interactions regarding the success rate of blood group identification. The study was conducted using 3 replications for each type of jeans fabric, which was carried out by exposing blood to a jeans fabric, leaving it in an indoor and outdoor environment for up to 336 hours (14 days), then continued by making a red blood cell suspension for comparison, and examining blood groups using the absorption-elution method. From the results obtained, it is known that the blood exposed in the jeans fabric that being placed indoor for up to 336 hours (14 days) can still be identified and has a success percentage rate of up to 100%. Meanwhile, the blood exposed on the jeans fabric that was placed outdoor could no longer be identified after 264 hours (11 days). Based on the result of this study, it can be concluded that the exposure time of 366 hours (14 days) for the indoor environment can still be identified properly, while the exposure time of 264 hours (11 days) for dry blood samples in the outdoor environment can no longer be identified. The indoor environment gives a better percentage of success than the outdoor environment in identifying blood types from dry blood samples. The best types of substrates that can store blood at an exposure time of up to 336 hours (14 days) are dry denim, black coated denim, and stretch denim.
