Experimental investigation on the thermal protective performance of nonwoven Fabrics made of high-performance fibers
Journal of Thermal Analysis and Calorimetry, 2015Co-Authors: Zhenglin Xu, Wenbin Li, Weidong YuAbstract:In this study, the thermal protective performance of nonwoven Fabrics made of Nomex (polyisophthaloyl metaphenylene diamine), PPS (polyphenylene sulfide), P84 (polyimide), and basalt fibers was investigated. The objective was to determine the influence of fiber type, thickness of fabric, and wet on the thermal protective performance of nonwoven fabric. The thermal resistances of different nonwoven Fabrics were measured using a dry hot plate instrument, the basalt nonwoven Fabrics had a highest thermal resistance in all fabric, and the thermal resistance of nonwoven fabric increased with the increase in thickness. The six nonwoven Fabrics were exposed to a hot environment for a few minutes by using a self-designed apparatus. The test results showed that the nonwoven Fabrics made with basalt fiber exhibited the best thermal protective performance, and the thermal protective abilities of nonwoven Fabrics increased with fabric thickness. Interestingly, nonwoven Fabrics with added water were found to be able to keep the fabric surface lower temperature compared to dry Fabrics when exposed to a hot environment, indicating the excellent thermal protective performance of wet nonwoven Fabrics.

structural parameters affecting tear strength of the Fabrics tents
alexandria engineering journal, 2017Co-Authors: Eman EltahanAbstract:Abstract The tearing strength is more vital in heavy duty Fabrics. So it is important to know the effects of the fabric structural parameters on the tearing resistance of these types of Fabrics. In this work the effects of some fabric structural parameters were studied on the tearing properties of Fabrics used in tents. The experimental work was divided into two parts; the first part was to study the effect of fabric design on the tearing strength. Six fabric designs of the same type of fiber were used. They were of different specific tightness. The second part was to produce Fabrics which are used in tents with different specifications. Different sets of fabric specimens were prepared. These specimens were tested for tearing resistance, to study the effects of these structural parameters on the tearing resistance of the Fabrics. The effects of the structural parameters on the tearing strength were deduced.

effect of lycra percentages and loop length on the physical and mechanical properties of single jersey knitted Fabrics
Journal of Composites, 2016Co-Authors: Eman EltahanAbstract:Single jersey knitted Fabrics are generally used to make underwear and outerwear such as T-shirts. Knit fabric can more easily deform or stretch by compressing or elongating the individual stitches that form the fabric. Cotton yarns, which are not elastomeric, do not have the ability of recovery to rearrange the stitches. As a consequence, single-knit Fabrics may have permanent deformation. To improve the recovery performance of circular single-knit Fabrics, it is now a common practice to knit a small amount of spandex fiber or yarn with companion cotton yarn. In this study the physical, dimensional, and mechanical properties of back plaited cotton/spandex single jersey knitted Fabrics were investigated and the results are compared with knitted Fabrics made from 100% cotton and the effect of spandex percentage was also studied. It was found that as the loop length increases, the wales density was not affected and specific fabric hand and extension increased, but bursting strength and fabric recovery decreased. The presence of Lycra in single jersey knitted fabric increases of course density, fabric thickness, and knitted fabric recovery, while fabric width, fabric porosity, and extension were decreased.

Flammability, comfort and mechanical properties of a novel fabric structure: plant-structured fabric
Cellulose, 2017Co-Authors: Ka-po Maggie Tang, Chi Wai Kan, Jin-tu Fan, Manas Kumar Sarkar, Sai-leung TsoAbstract:Traditional flame retardant (FR) treatments may bring detrimental effects on comfort as well as mechanical properties for cotton Fabrics. This study investigates whether a novel fabric structure—plant-structured fabric can improve fabric performance after FR treatment. Here, plant-structure Fabrics were compared with conventional Fabrics of similar weight and thickness. The results revealed plant-structured Fabrics tended to retain a higher level of comfort properties than the conventional plain and twill weave Fabrics on wettability, thermal conductivity, air resistance and fabric hand feel. Moreover, the tearing strength and tensile strength of the plant-structured Fabrics are strongly associated with a higher level of flame resistance as evaluated by the 45° flammability test. This can be attributed to higher fabric sett, the presence of closed pores between the two layers and lower open pore volume at its face. The weave pattern of Fabrics was observed through microscope and the thermal decomposition behaviour of Fabrics was evaluated by thermal gravimetric analysis.

A statistical analysis of low-stress mechanical properties of warp-knitted Fabrics:
Textile Research Journal, 2016Co-Authors: Ka Yan Yim, Chi Wai KanAbstract:Fabric hand is an indispensable characteristic for the selection of fabric and product development and the buying consideration for manufacturers and consumers. However, there is little comprehensive work on the hand feel property of warp-knitted Fabrics due to the mainstream natural fibers (cotton, wool and silk) and other fabric structures (woven, weft-knitted and nonwoven). The increasing potential for the wide variety of applications and development of warp-knitted Fabrics is not only because its fabric hand gives better determination for fabric marketing, but also because it provides extensive scope for fabric performance and appearance. This paper reports an experimental study on the integrated fabric hand behavior of a series of warp-knitted Fabrics made for various apparel applications, such as sportswear, lingerie and leisure wear. These 105 Fabrics were produced by varying different physical parameters, including fabric weight and fabric thickness. The Kawabata Evaluation System for Fabric (KES-...

An evaluation of UV protection imparted by cotton Fabrics dyed with natural colorants
BMC Dermatology, 2004Co-Authors: Ajoy K SarkarAbstract:Background The ultraviolet properties of textiles dyed with synthetic dyes have been widely reported in literature. However, no study has investigated the ultraviolet properties of natural Fabrics dyed with natural colorants. This study reports the Ultraviolet Protection Factor (UPF) of cotton Fabrics dyed with colorants of plant and insect origins. Methods Three cotton Fabrics were dyed with three natural colorants. Fabrics were characterized with respect to fabric construction, weight, thickness and thread count. Influence of fabric characteristics on Ultraviolet Protection Factor was studied. Role of colorant concentration on the ultraviolet protection factor was examined via color strength analysis. Results A positive correlation was observed between the weight of the fabric and their UPF values. Similarly, thicker Fabrics offered more protection from ultraviolet rays. Thread count appears to negatively correlate with UPF. Dyeing with natural colorants dramatically increased the protective abilities of all three fabric constructions. Additionally, within the same fabric type UPF values increased with higher depths of shade. Conclusion Dyeing cotton Fabrics with natural colorants increases the ultraviolet protective abilities of the Fabrics and can be considered as an effective protection against ultraviolet rays. The UPF is further enhanced with colorant of dark hues and with high concentration of the colorant in the fabric.

experimental determination of yarn pull out properties of para aramid kevlar woven fabric
Journal of Industrial Textiles, 2012Co-Authors: Kadir BilisikAbstract:The aim of this study was to determine the pull-out properties of the para-aramid woven Fabrics. Para-aramid Kevlar 29® (K29) and Kevlar 129® (K129) woven Fabrics were used to conduct the pull-out tests. K29 and K129 woven Fabrics had high and low fabric densities, respectively. For this reason, yarn pull-out fixture was developed to test various K29 and K129 fabric sample dimensions. Data generated from single and multiple yarn pull-out tests in various dimensions of K29 and K129 woven Fabrics included fabric pull-out forces, yarn crimp extensions in the Fabrics, and fabric displacements. Yarn pull-out forces depended on fabric density, fabric sample dimensions, and the number of pulled ends in the fabric. Multiple yarn pull-out force was higher than single yarn pull-out force. Single- and multiple-yarn pull-out forces in K29 (tight fabric) were higher than those of K129 (loose fabric). Yarn crimp extension in K29 and K129 Fabrics depended on crimp ratio in the Fabrics and fabric density. High crimp rati...

Tensile and Tearing Properties of Newly Developed Structural Denim Fabrics after Abrasion
Fibres & Textiles in Eastern Europe, 2011Co-Authors: Kadir Bilisik, Gaye YolacanAbstract:AbstractThe aim of this study was to assess the tensile and tearing properties of newly developed structural denim Fabrics after an abrasion load and to compare them with those of tradi-tional denim fabric. The Fabrics developed were designed as large and small structural pattern and traditional denim fabric. All the denim Fabrics were first abraded, and later tensile and tearing tests were performed on them seperately. The tensile properties of the abraded large structural pattern denim Fabrics were generally inferior to those of the small structural pattern and traditional denim fabric. When the abrasion cycles were increased, the tensile properties of all the denim Fabrics generally decreased. The weft directional tearing strength of the small structural pattern denim fabric was significantly higher than that of the traditional and large structural pattern denim Fabrics. When the abrasion cycles were increased, the tearing properties in the weft and warp of all the denim Fabrics gener-ally decreased.
