Environmental issues are nowadays the prime concern worldwide for leather industries due to chrome containing solid and liquid wastes generated from the tannery. Therefore, experts are being encouraged in exploring alternative tanning agents. This study aimed at applying a novel vegetable tanning agent extracted from Xylocarpus granatum barks for the production of semi-chrome (SC) and chrome retanned (CR) leathers to reduce chromium use. Characterization of the SC and CR leathers was performed by Fourier Transform Infrared (FTIR) spectroscopy which revealed prominent tanning activity of the extracted tannins. The tanned leathers exhibited shrinkage temperatures of 112˚C for SC and 103˚C for CR leathers. The physicomechanical properties were found as tensile strength >230 kg/cm2, tear strength >30 kg/cm, grain cracking load >20 kg, distention at grain crack >7 mm, ball bursting load >38 kg, and distention at ball bursting >12mm that was comparatively acceptable according to UNIDO standard for shoe upper leathers.

The final attenuation and twisting of fiber take place at ring spinning machine and hence its optimized performance is very crucial in terms of yarn quality. Drafting at ring spinning machine has a decisive effect on quality. There exist many influencing parameters in the spinning geometry that have to be optimized for manufacturing of quality yarn. The present research work was carried out to develop the Artificial neural networks (ANN) based prediction model for the polyester/cotton blended ring spun yarns by using these influencing parameters as inputs. ANN prediction model was developed using resilient backpropogation algorithm. Yarn quality parameters like yarn evenness, hairiness and tensile parameters were predicted. The low mean absolute error values for the yarn quality parameters proved that it is possible to predict the yarn quality on the basis of spinning geometry for cotton/polyester blended ring spun yarns using Resilient Back Propogation Neural Networks.

The ultrasonic welding process allows economically efficient and safe for the workers waterproof joining of textile materials and is applied in the production of various technical textiles, protective clothing, and other types of textile products. In this latest research work, a flexible, textile-based heating element is produced by the connection of waterproof laminated textiles using ultrasonic technique. This novel product allows completely new options for the design of flexible heating and cooling elements for rooms and various other applications but requires high quality seams. This work starts with the theoretical background about the heating of the textile until reaching the welding temperature within the welding zone. The heat flow through the volume of the welded textiles is investigated numerically using Finite Element Method software. The simulation is performed for different sizes and configurations of the seam allowances, so that options between overlapping only in the pressed area without side allowance (no free allowance), small allowance, and larger allowance are simulated. These simulations demonstrate different distributions of the temperature in the seam cross-section at the different configurations, because of the different amounts of textile material around the welding place.

In this study, it was aimed to use the synthesized Ag-TiO2 and commercial ZnPT complexes in the development of antimicrobial textile. As a result of these studies; Ag-TiO2 and ZnPT complex have antimicrobial activity against all test microorganisms including E. cloaceae, E. faecalis, S. typhimirium, S. epidermidis, P. vulgaris, Y. pseudotuberculosis, S. aureus, P. aeruginosa, K. pneumoniae, B. subtilis, E. coli, L. monocytogenes and C. albicans. Optimum conditions of application on cotton textile sample were determined as full bath applying at 50oC for 60 min. and drying at 70oC for 60 min. Optimum concentration values for the application were determined as 4g/L for Ag-TiO2 and 0.01g/L for ZnPT, and these values were shown as bacteriocidal concentration (MBC) by shake-flask method. Furthermore, it has been determined that the antimicrobial activity of textile samples are durable up to 10 repeated washings and are permanent for more than 25 days.

Shirt manufacturing involves fusing the cut parts with an interlining. Shrinkage in these components leads to puckering, mismatched design between fused and non-fused components, and increased fabric consumption. The study aims to explain the effect of ten factors – fabric (content, weight, weave structure, cover, and finish), interlining (weight, finish), fusing time, temperature and pressure – on thermal and relaxation shrinkage of the fused plackets. The results show that the thermal shrinkage in the placket is influenced by three factors (interlining finish, weight and temperature), and relaxation shrinkage of placket samples is influenced by three factors (fabric fibre content, temperature and pressure). The lower weight interlining with a raised finish used for shirt plackets are found to shrink when fused. After washing, the cotton placket shrunk more than the polycotton plackets. The optimised process condition for a specific fabric and interlining is proposed in the study.

This paper focuses on preparation of poly(vinyl alcohol) (PVA)-based composites reinforced with okra bast fibers at different percentages of 5, 10, 20% via solution casting method. Fibers obtained from different sections of okra plants were biologically degummed and scoured with Na2CO3. Selected fibers were bleached, treated with maleic anhydride or grafted with vinyl acetate. Mechanical, physical and biodegradational properties of the composites were investigated. The tensile strength of the produced composites ranges between 33.8 and 55.1 MPa, elasticity modulus from 1.8 to 2.6 GPa, elongation rate at break varies in 2.8-10%. Chemical treatments led to improved mechanical performance whereas increased fiber content reduces tensile strength, stiffness and elongation, as well as water absorption. Fiber addition significantly affected biodegradation in a complicated way: by decelerating mass loss but accelerating deterioration of mechanical properties.

In this study, polyester matrix composites reinforced by 1x1, 2x2, half- and full-cardigan rib pattern weft-knitted fabrics from glass and glass/aramid hybrid yarns were produced. Tensile, flexural and impact tests were applied to the composites. The 2x2 rib pattern composite showed the highest thickness and density. The hybridization of glass yarn with aramid yarn increased the thickness, while it decreased the density of composites. The 2x2 rib pattern composite showed the highest tensile modulus and tensile strength. Yarn hybridization increased tensile strength at statistically significant level. The composite with full-cardigan rib pattern displayed considerably higher flexural modulus and flexural strength than the composites with the other patterns. When glass and hybrid composites were considered separately, the rib fabric pattern exhibited significant effect on maximum load. The rib fabric pattern displayed also significant effect on absorbed energy for glass composites. The yarn hybridization dramatically increased maximum load and absorbed impact energy.

This article presents the design, fabrication and analysis of a textile-based band-stop frequency selective surface (FSS), in GSM, WiFi, LTE and WiMAX bands where the electromagnetic (EM) pollution is intense. The unit cell of the proposed FSS has been designed and simulated via a full-wave EM solver; CST Microwave Studio at the frequency of interest. In contrary to traditional FSS designs, which are printed on solid materials such as PCBs, this study presents an FSS considering a woven fabric as a substrate layer having features such as flexibility and compact weight. Two fabrication techniques have been considered one is conducted with a copper tape having a thickness of 35 µm denoted as CT FSS and the second one is conductive yarn embroidering technique denoted as CY FSS for the conducting pattern. Fabricated samples are evaluated in terms of transmission characteristics and a satisfactory agreement is obtained between CT FSS and CY FSS for both simulations and fabricated prototypes.

This study aims to characterize and evaluate polyethylene oxide (PEO) and chitosan (CS) nanofibers produced by electrospinning method. Electrospinning solutions were used at three different concentrations (1, 2, 3 wt%) with five different PEO/CS mixing ratios (30/70, 40/60, 50/50, 60/40, 100/0). FESEM, XRD and FTIR tests were applied for characterization of the nanofibers. Antibacterial activity of the nanofibers against Staphylococcus aureus and Klebsiella pneumoniae microorganisms was investigated using disk diffusion method. While 1 wt% of concentration was not suitable to obtain regular nanofibers, the nanofibers were uniform and largely free of beads at the other ones (2, 3 wt%). The average diameters of the nanofibers varied from 59 to 298 nm depending on the concentration and mixing ratio. Strong hydrogen bonds were formed between two polymers, while the crystal structure of PEO did not change significantly when mixed with chitosan. The PEO/CS nanofibers showed no resistance to the selected bacteria.
