Aiming at demonstrating the potential of unidirectional natural fiber-reinforced thermoplastic composites in structural applications, textile flax yarn/thermoplastic polyester composites with variable fiber volume fractions have been manufactured by a filament-winding process followed by a vacuum-assisted compression molding process. The microstructure of the composites shows that the flax fibe...

Taguchi Method is explained in brief and one of the textile processes, called spinning process, is optimised by using Taguchi method for manufacturing optimum packing density of different technologies yarns. The effect of process variables like: lap hank, card draft, draft/doublings and drafts at speed frame, ring frame, rotor and air-jet spinning machine on packing density parameters of respec...

The variations in the mechanical and surface properties of cotton ringand OE rotor-spun yarns on exposure to different chemicals during wet processing have been studied. It is observed that the structure and yarn twist are the dominant parameters in determining the accessibility of chemicals during wet processing. The most distinct outcome of alkaline scouring of cotton yarns, in comparison to ...

The desmoglein 4 (DSG4) gene is a potential candidate in the search for genes that may affect wool traits, because of its function. This study aimed to screen for polymorphisms in partial exon 16 and 3ꞌUTR of the sheep desmoglein 4 DSG4 gene, and to test its possible association with wool length and crimp associated with fur. Overall, 326 sheep were scanned via single-strand conformational poly...

Special properties of Iranian wool such as elasticity compared with Merino wool leads to more popularity of Persian carpet at an international level. By using of finishing process it is possible to improve some of the physical properties of wool fibers such as fleece modification, increasing of lightness and whiteness and producing a smoother surface that result a better quality carpet. In this...

The problem of a rotating transported thread or yarn occurs in textile applications such as high-speed spinning and unwinding from a cylindrical package. In case of low tension the yarn is known to buckle and fly out under the action of centrifugal forces. The motion initially appears fixed when viewed from a rotating coordinate frame and is known as ballooning (see [1], which also contains ref...

Modeling of yarn and fiber properties has been a popular topic in the field of textile engineering in recent decades. The common method for fitting models has been to use classical regression analysis, based on the assumptions of data crispness and deterministic relations among variables. However, in modeling practical systems such as cotton spinning, the above assumptions may not hold true. Pr...

Wool fibres have been chemically modified by reduction I chlorination under acidic pH Ipre-swelling in conc. formic acid prior to their dyeing with indigenous reactive dyes of different molecular configurations to enhance the reactive dye uptake on wool fibre substrate. The pretreatment processes are inexpensive, less harmful and less time consuming as against the use of imported special wool r...

The hypothesis that infrequent feeding of sheep supports a higher rate of wool growth than frequent (daily) feeding was examined using oats grain and three roughages of varying protein content. The wool growth of Merino ewes fed every third and sixth day was significantly greater than that of similar ewes fed every day, when averaged over the four diets. Increased wool production due to infrequ...

Tea is a popular product known worldwide with health benefits for consumers. For centuries, it has been considered safe and healthy beverage. Although the tea plant many beneficial effects on human health, chemicals that can be found in cause negative health. Recently, use of dyes teas comes to fore among imitations or adulterations made foods recently. These substances pose risk.The purpose th...
