The study was aimed to check the effect of eco-friendly antimicrobial finish on 100% polyesterand 50/50 cotton/polyester woven fabrics. The leaves’ extract of Butea monosperma was used as an eco-friendly antimicrobial finish. The fabric was first desized, scoured, bleached and washed then antimicrobialfinish was applied by using pad dry cure method. The aesthetic, comfort and mechanical fabrics propertieswere checked before and after applying antimicrobial finish. Under aesthetic property stiffness andsmoothness appearance was checked, under comfort related property absorbency and air permeability waschecked and under mechanical property tear and tensile strength was checked. The antimicrobial finishwas checked by using ASTEM E2149 Shake Flask method. The AATCC and ISO standard testing methodswere used for checking fabric properties. One way ANOVA statistical test was applied for analysis ofresults. Antimicrobial finish has increased aesthetic (stiffness, smoothness appearance), comfort (absorbency,air permeability) and mechanical (tensile and tear strengths) properties of polyester and cotton/polyesterfabrics.

Purpose The purpose of this paper is to study the 100 percent pure cotton and 50:50 cotton and regenerated fibers (tencel, modal, bamboo, viscose) blends. The blends of regenerated fibers with cotton are studied so as to replace 100 percent cotton fabrics with the cotton blends as cotton cannot fulfill the demand of clothing due to the increasing population. Design/methodology/approach In order to conduct this study, cotton, as natural cellulose fiber, was used. Regenerated fibers include viscose, tencel, modal and bamboo. Five yarn samples of Ne 30/1 of 100 percent cotton and blends (50:50) of cotton with tencel, modal, bamboo and viscose fibers were produced. The blending was done in the Blow-room, and yarn samples were produced by employing the ring spinning technique. Plain woven fabrics samples with Ends (76) and Picks (68) per inch of 120 gsm were prepared. The fabric samples were tested for mechanical (warp and weft tensile and tear strengths) and comfort properties (air permeability, moisture management and thermal resistance). Findings Cotton:tencel fabric has the excellent mechanical (tensile and tear strength) as well as comfort properties (air permeability, moisture management and thermal resistance). It means that the most suitable blend that cotton can make with the regenerated fibers is the tencel. Therefore, to have more comfortable fabrics, the fabrics which are being made by 100 percent cotton can be replaced with the cotton:tencel. Originality/value To the authors’ information, no study has been reported in which all the regenerated fibers blended with cotton were studied. Hence, the aim of this work is to study the mechanical and comfort properties of the regenerated fibers (modal, tencel, viscose and bamboo) blended with cotton. The blends of cotton with regenerated fibers might replace 100 percent cotton in clothing applications as cotton cannot fulfill the increasing demanding of clothing.

This study was designed to explore the relationship between sunlight exposure and the mechanical properties of paragliding fabrics which have different colors, densities, yarn counts, and coating materials. This study exposed 5 different colors of paragliding fabrics (red, turquoise, dark blue, orange, and white) to intense sunlight for 150 hours during the summer from 9:00 a.m. to 3:00 p.m. for 5 days a week for 5 weeks. Before and after the UV radiation aging process, the air permeability, tensile strength, tear strength, and bursting strength tests were performed. Test results were also evaluated using statistical methods. According to the results, the fading of the turquoise fabric was found to be the highest among the studied fabrics. It was determined that there is a significant decrease in the mechanical properties of the fabrics after sunlight exposure. After aging, the fabrics become considerably weaker in the case of mechanical properties due to the degradation in both the dyestuff and macromolecular structure of the fiber

Purpose. The objective of this study was to evaluate the marginal fit and the flexural resistance of nickel-chromium frameworks welded by different techniques, gas-torch, laser, and tungsten inert gas (TIG), compared with that of frameworks made via one-piece casting. Methods. To evaluate the marginal fit, a master model was fabricated simulating four implants. Transfers and replicas were used to transfer the positions of the implants to the model, using a silicone matrix. The bars were waxed up and casted. Three assessments of misfit were performed for each implant using a stereomicroscope before and after welding in two predetermined regions, totaling six readings for each implant. To evaluate the flexural resistance, one group was made casting the specimens in one piece. Other 3 groups using gas-torch, laser, and TIG welding techniques were made after sectioned transversally. The data showed normal distribution and two-way ANOVA for marginal fit and one-way ANOVA for flexural resistance, and Tukey’s posttest (α=0.05) was performed. Results. For the marginal fit, the three welding methods presented similar results and were different from one-piece casting. For the flexural resistance, significant differences were observed among the studied groups (p<0.001), and the one-piece group presented higher resistance compared to the three welding techniques. Conclusions. Within the limits of this study, the three welding techniques yielded similar misfit results, and the laser and TIG techniques presented similar flexural resistance but lower than gas-torch and one-piece casting.

AbstractThis study investigates physicochemical impact of ultrasonic irradiations on surface topography of woven fabrics. In a simultaneous in-situ sonochemical method, the synthesis and coating of zinc oxide nanoparticles (ZnO NPs) on woven textiles were successfully achieved. Different instruments i.e. Alambeta, moisture management tester, air permeability tester and permetester were utilised during experimentation for thermal evaluation, moisture transportation and air permeation. The results regarding thermophysiological comfort of ZnO coated fabrics were evaluated on the basis of thickness and ZnO NPs coated amount on fabrics. In addition, the achieved results depict the impact of sonication (pressure gradient) on surface roughness of cotton and polyester. The coating of ZnO NPs on fabrics, crystal phase identification, surface topography and fluctuations in surface roughness were estimated by inductively coupled plasma atomic emission spectroscopy (ICP-AES), X-ray Diffractometry (XRD), ultrahigh-resolution scanning electron microscopy (UHR-SEM) and energy dispersive X-ray (EDX). Moreover, thermophysiological properties i.e. thermal conductivity, absolute evaporative resistance, thermal absorptivity, air permeability, overall moisture management capacity and relative water vapour permeability of untreated and ZnO treated samples were evaluated by standard test methods.
