Abstract:

This paper reports a comparative experimental study of single jersey knitted fabrics made from a novel bio-based and degradable polylactide acid/poly (hydroxybutyrate-co-hydroxyvalerate) (PLA/PHBV) multi-filament yarn, together with polylactide acid , Cupro, polyethylene terephthalate (PET) and polyamide 6 (PA 6) multi-filament yarns. Their structures, mechanical, thermal and surface properties and performances as well as anti-bacterial behavior are measured and compared. It has been found that the polylactide acid/poly (hydroxybutyrate-co-hydroxyvalerate) (PLA/PHBV) filament yarn has adequate thermal and mechanical properties for normal textile and coloration/finishing processes. The Young's modulus of polylactide acid/poly (hydroxybutyrate-co-hydroxyvalerate) (PLA/PHBV) multi-filament yarn is the lowest among all the candidates investigated except for polyamide 6 (PA 6). The dyed polylactide acid/poly (hydroxybutyrate-co-hydroxyvalerate) (PLA/PHBV) fabric has the highest softness rating among all the fabrics. Single jersey knitted fabrics from the polylactide acid/poly (hydroxybutyrate-co-hydroxyvalerate) (PLA/PHBV) filament yarn have a bursting strength, extension and recovery that satisfy the industrial requirement. In addition, after fully relaxation, the dyed polylactide acid/poly (hydroxybutyrate-co-hydroxyvalerate) (PLA/PHBV) knitted fabrics exhibit an outstanding pilling resistance, favorable snagging property, as well as good air permeability, Qmax and smoother surface. Finally, this study has led to a discovery of excellent anti-bacterial performance of 100% polylactide acid/poly (hydroxybutyrate-co-hydroxyvalerate) (PLA/PHBV) fabrics against staphylococcus aureus, klebsiella pneumoniae, candida albicans according to AATCC100-2012.

Abstract:

The work is devoted to the study of the geometric parameters of a knitted loop. It has been found that the optimal model is a loop model detailed at the yarn level, which considers the change in the cross-sectional shape and sets the properties of the porous material in accordance with the internal porosity of the yarn. A mathematical description of the coordinates of the characteristic points of the loop and an algorithm for calculating the coordinates of the control vertices of the second order spline, which determine the configuration of the yarn axes in the loop, are presented in this work. To create 3D models, Autodesk AutoCAD software and Structura 3D software, developed in the AutoLisp programming language, were used. The simulation of the air flow process was carried out in the Autodesk CFD Simulation environment. For the experimental investigation, plane knits from 44 tex × 3 linear density ultra-high molecular weight polyethylene yarns were produced, and their air permeability was tested according to Standard DSTU ISO 9237:2003. The results obtained during the laboratory experiment and simulation differed by less than 5%.

Abstract:

In order to study the wearability of multi-component blended fabrics, there are 9 kinds of fabrics which belong to A, B and C three series were woven. They were blended with different proportions e.g. PTT, PLA, Cooldry, triangular shaped polyester yarn, cotton, hemp, viscose, conductive filament, and so on. Anti-pilling property, crease recovery, drapability, moisture transmission and air permeability of the fabrics were tested and analyzed. From the test results, following conclusions can be gotten. 1) The anti-pilling property is good for fabrics with tighter weave construction; 2) The crease recovery is good for fabrics with smaller weft density; 3) The moisture permeability is good for fabrics with smaller tightness; 4) The crease resistance, drapability, moisture permeability and air permeability of the fabrics can be improved by looser weave construction and smaller binding point.

Abstract:

Continuous multi-filament boron nitride fibers have been prepared on a large scale using the melt drawn technique from a low-cost boracic acid. Boracic acid was heated to obtain the molten boric oxide in a melting tank. Molten boric oxide was melt spun in a conventional manner through an 200-tip bushing to produce a continuous multifilament yarn consisting of 200 filaments of boric oxide. Boric oxide fibers were nitrided in an ammonia and were annealed in an inert atmosphere while simultaneously subjecting the fibers to sufficient longitudinal tension as to at least prevent longitudinal shrinkage of the fibers. The resulting fibers, consisting essentially of boron nitride, were less than about 8 μm in diameter and greater than 500 m in length. It indicated that the boron nitride fibers has a sound mechanical function with tensile strength of 1.40 GPa. The continuous boron nitride fibers of high-performance were especially suitable for reinforcing plastic, ceramic or metal matrices in the preparation of fiber reinforced composites.

Abstract:

The relationship between the axial inserted yarns and the mechanical properties of the multi-angled filament wound pipes was studied by experimental investigation in this paper. Firstly, the glassfiber/epoxy pipes with different process parameters were fabricated on the specially-designed filament winding equipment under varying conditions. Then the specimens were made in terms of standard sizes and tested under axial tensile load and axial compressive load, respectively. Furthermore, the axial tensile strength and the axial compressive strength were obtained from the test data, which showed that the above two values of the specimens with the axial yarns were larger than that without the axial yarns. That is to say, the incorporation of the axial reinforcement was found to result in increased strength.

Abstract:

Cool-touch nylon multi-filament yarns with good heat transfer performance are widely used in the development of knitted fabrics for summer and sports clothing. However, the physical properties of cool-touch nylon fibres, and the effect of fineness and cross-section on comfort-related properties of their knitted fabrics are still not well understood. In this study, the physical properties of cool-touch nylon fibres and common nylon fibres, and comfort properties of knitted fabrics from both fibre types were measured and compared. It was found that cool-touch nylon fibres have better moisture absorption, but slightly lower crystallinity than common nylon fibres. Regarding the fibre fineness and cross-section of cool-touch nylon and common nylon, knitted fabrics showed a similar dependence on thermal comfort properties. Cool-touch nylon fabrics had increased wicking capacity, thermal transfer, and cooling properties, but poorer drying performance and moisture permeability compared to common nylon fabrics. It was concluded that using nylon multi-filament yarns made up of finer filaments and cool touch filaments is an effective way to develop thermal-wet comfort knitted fabrics for summer and sports clothing applications.

Abstract:

Three dimensional (3D) warp interlock fabric becomes a promising structure due to its good mechanical performances. However, its complex manufacturing process can cause severe yarn damage and affects its overall final performances. The current study addressed the effects weaving process and warp yarn ratios on the multi-filaments yarn degradations and its mechanical performances while 3D warp interlock fabric manufacturing. Four different 3D warp interlock variants having similar fabric architecture, and yarn densities but different warp yarns interchange ratios were manufactured using 930dTex high-performance multi-filament (Twaron® f1000). The multi-filaments yarns at different weaving processes were tested for their tensile properties. The results show that the average tensile strength of twisted yarns show a decrement of 5.68% as compared to the bobbin yarns. Meanwhile, warping process also showed a 16.11% maximum breaking load reduction as compared to the bobbin yarn. Besides, the tensile strength of binding yarn after weaving process for samples 3D-8/0, 3D-8/4, and 3D-8/8 was reduced by 12.79%, 5.22%, and 14.22% respectively as compared to the yarn after warping process. In conclusion, yarn degradation inside the 3D woven structure was affected not only by the various process parameters but also by the type of fabric architecture made with different warp yarn ratios. These phenomena ultimately bring a great influence both on the yarn and overall mechanical performance of the final products. For this, further studies are planned to investigate the multi-filaments yarn degradation effect on the ballistic performances fibrous material as it is directly linked to the yarn performance.

Abstract:

In this paper we analyze the performance of a bond layer between the multi-filament yarn and the cementitious matrix. The performance of the bond layer is a central issue in the development of textile-reinforced concrete. The changes in the microstructure during the loading result in distinguished failure mechanisms on the micro, meso and macro scales. The paper provides a brief review of these effects and describes a modeling strategy capable of reflecting the failure process. Using the model of the bond layer we illuminate the correspondence between the disorder in the microstructure of the yarn and the bonding behavior at the meso- and macro level. Particular interest is paid to the influence of irregularities in the micro-structure (relative differences in filament lengths, varying bond quality, bond-free length) for different levels of local bond quality between the filament surface and the matrix.

Abstract:

Abstract In this paper, the mechanical characteristics of Kevlar multi-filament-polypropylene (KV M/F-PP) hybrid yarns and its composites have been studied. The hybrid yarns have been prepared by the principle of friction spun method in a DREF-3 (Dr Ernst Fehrer A.G. the name of the inventor 1973) Machine. The system uses Kevlar-29 (poly paraphenylene terephthalamide) multifilament (KV M/F) and polypropylene (PP) of 38 mm staple length fibres as core and sheath materials, respectively. The tensile properties of selected reinforcing materials and hybrid yarns are tested before preparing the composite samples. The weight percentages of KV M/F were kept as 0%, 15%, 20%, 25% and 30% corresponding to the percentages of matrix. DREF-3 hybrid yarns are characterized by very homogeneous component distributed over the yarn cross-section. The hybrid yarn is used for thermoplastic composites in compression molding, where Kevlar multifilaments take place in core as reinforcing materials and sheath or wrapped PP fibres as matrix. The prepared composite samples have been studied using specific standards to evaluate the void volume fraction and the tensile behavior in the standard conditions. The composite having 30% of Kevlar shows the highest tensile strength with a high void percentage, however, the elongation to break is a minimum due to lower weight percentage of low elastic modulus polypropylene matrix as compare to other samples.

Abstract:

In the present study, filament wound pipes were fabricated by glass and polypropylene (PP) yarns with the three different filament winding angles 55°, 70°, and 82°. Glass and PP yarns were wound around the pipe with two methods; layered and hybrid. Epoxy resin was applied as a matrix to manufacture composite samples. It should be mentioned that composite samples were made in different layers. The three-point bending test was carried out on all samples to investigate the bending behavior of the composites. The experimental results showed that the winding angle 55° is better than other angles in terms of improving the flexural strength of the composite. Moreover, using hybrid yarn to fabricate the composite sample increases the flexural strength and energy absorption of the composite. In the next step, a multi-scale finite element model was applied to predict the flexural behavior of the composites. In this model, a unit-cell of each composite structure was modeled at the meso scale and elastic constants of the composites were extracted by a Python code. In addition, failure parameters for the composites were determined according to micromechanical equations. All elastic and failure parameters were utilized for the macro model and simulation three-point bending test. The numerical results were compared with the experimental and a good agreement could be observed between numerical and experimental results. So, the proposed model is proper to predict the mechanical behavior of the filament wound composite with high accuracy.

Abstract:

This paper investigates the failure mechanism and fabric ballistic performance of real-size multi-layer 2D woven fabrics impacted by sharp-edge fragment simulating projectile (FSP). First, the relations between digital fiber shear force and bending rigidity are established under the modified digital element approach (DEA) framework. Then, a systematic parametric study was carried out on the ballistic impact of a 4-inch-long single yarn and 4-inch by 4-inch 2D woven fabric at near fiber level to solve for the relations of digital fiber moment of inertia and ballistic limit. The results show that for the same number of digital fibers per yarn model, the simulated ballistic limits are in direct proportion to digital fiber moment of inertia. The increase of the number of digital fibers per yarn, however, decreases the digital fiber moment of inertia effect on ballistic limits. Second, the 1- to 28-layer real-size 2D woven Kevlar KM2 fabrics are simulated at filament level against FSP on the cluster to estimate the V50 zone. The perforation process and failure mechanism of 4-layer fabric is investigated and analyzed in detail. The simulation results demonstrate the deformed fabric shape with respect to time and the damage modes at the impact area. Numerical results are compared with standard ballistic test results.

Abstract:

The main goal of the presented study was to develop new multi-layered weft-knitted structure for thermal insulation and to investigate the dynamic of the heat transfer through this fabric. For knitting of outer and inner layers of this structure, different raw materials of yarns were used, i.e. wool, cotton, polyester and acrylic yarns. All the newly developed multi-layered weft-knitted fabrics show thermal insulation as, after 1 h of observation, temperature on the outer layer of all tested fabrics does not reach 40℃, i.e. the temperature of a heated plate. The results of this research showed that the nature of the yarns has a significant influence on the air permeability and dynamic of the heat exchange through the multi-layered structure, as it influences porosity of the knitted fabric. The results showed that the best fabric was the one where the outer layers are knitted from woollen yarns and the inner layer from polyester filament yarns.
