Tearing Strength

Fading increases the aesthetic properties of garments produced from denim fabrics. Different fading processes (e.g., laser fading, hand sand brushing, and potassium permanganate (PP) spraying) are applied on denim fabric to modify fabric appearance. A new approach was developed using gamma irradiation prior to the fading process. A design was produced using a CO2 laser for 130 μs. The same design was produced by hand sand brushing and PP spraying. Physical, mechanical, color, and other aesthetic properties were tested, including fabric grams per square meter (GSM), fastness to rubbing and abrasion resistance, tensile and tearing strength, color change (ΔE) values, yellowness index (YI), and color strength (K/S).

Abstract In this study, indigo-dyed denim fabric was decolorized by washing and printing with separate and simultaneous applications of laccase enzyme, sodium hydrosulfite, and cellulase enzyme. In this regard, the surface reflectance and color coordinates of the discolored fabrics were analyzed, and SEM photographs of the treated fabrics were prepared to analyze their surfaces. Finally, the effects of the discoloration process and materials on various parameters of the treated samples were investigated, including moisture content, creaserecovery angle, air permeability, and abrasion resistance. The color experiments showed that the discoloration mechanism with the combined use of laccase enzyme, sodium hydrosulfite, and cellulose enzyme had a significant effect on the improvement of the lightness (L*) of the samples, as the lightness of the treated samples was improved by 101.18 percent and 55.79 percent in both printing and washing, respectively. Furthermore, examination of specimen color coordinates revealed that the hue of the treated samples was changed to blue and green, and the purity of color (C*) was improved. The increased moisture content and air permeability of the treated specimens suggested that the comfort of the jeans clothing provided by these treatment methods had improved. As a result, it should be noted that the mediating action of sodium hydrosulfite was significantly influential for discoloration of denim with the laccase enzyme.

In this article, it is aimed to determine the effect of the antibacterial finishing process applied to bed linen fabrics, which are widely used in the market, on some mechanical properties of the fabric. Antibacterial finishing process was applied to the fabric produced for this purpose under operating conditions and wrinkle strength, tear strength and abrasion resistance levels were made on these fabrics. Measurements were made before and after antibacterial finishing. The resulting results were evaluated among themselves and processed in SPSS (Statistical Package for Social Sciences) 21.0 program. Since the number of processed data is less than 50 according to greige fabric and antibacterial treated fabric measurements, it has been tested with Shapiro-Wilk analysis. The homogeneity of the test variances of the data was done with Levene homogeneity test. Tear strength, creasing angle and abrasion resistance test results are focused on how scientifically meaningful the effects of process parameters and interactions on fabric properties are in accordance with statistical analysis. As a result of the analysis, it was revealed that the results obtained from the tear strength, wrinkle angle and abrasion resistance tests were statistically significant and as a result, the antibacterial process parameters negatively affect the wrinkle strength, tear strength of the cotton fabric; it was found to affect the wear resistance positively.

Resistance Performance

This study aims to design and develop denim fabrics with enhanced mechanical and impact abrasion resistance performance using different materials, yarn types and fabric constructions. It was aimed to reach the standard impact abrasion resistance requirements of motorcycle protective clothing for Level 1 in high impact areas of the body (zones 1 and 2), such as hip and knee areas. The existence of cotton/Cordura® yarn in warp and T400 polyester yarn in the weft and the use of higher yarn densities increased the performance in tensile strength and impact abrasion resistance, compared to a classical cotton denim fabric. The use of coarser yarns and fabrics with a double weave construction increased impact abrasion resistance compared to single layer cloths. The double and backed cloth samples developed with cotton/Cordura® and Kevlar®/polyester yarns in their construction showed impact abrasion resistance times over 4 s and reached the “EN 13595-2:2002 Level 1 abrasion resistance” standard requirement.

Abrasive Finishing

In this paper the Magnetic Abrasive Finishing (MAF) was utilized after Single Point Incremental Forming (SPIF) process as a combined finishing process. Firstly, the Single Point Incremental forming was form the truncated cone made from low carbon steel (1008-AISI) based on Z-level tool path then the magnetic abrasive finishing process was applied on the surface of the formed product. Box-Behnken design of experiment in Minitab 17 software was used in this study. The influences of different parameters (feed rate, machining step size, coil current and spindle speed) on change in Micro-Vickers hardness were studied. The maximum and minimum change in Micro-Vickers hardness that achieved from all the experiments were (40.4 and 1.1) respectively. The contribution percent of (feed rate, machining step size, coil current and spindle speed) were (7.1, 18.068, 17.376 and 37.894) % respectively. After MAF process all the micro surface cracks that generated on the workpiece surface was completely removed from the surface.
