Studies on Yarn Hairiness of Polyester/Cotton Blended Ring-Spun Yarns Made from Different Blend Ratios

Abstract

In this study, 1.4 denier and 32 mm of fiber-length polyester and 30.2 mm fiber-length cotton (4.35 micronaire) rovings of 695 tex (αtex = 10.7) were blended with different polyester/cotton ratios (i.e. 17/83, 33/67, 50/50, 67/33, and 83/17). The yarns were produced at a spindle speed of 11,000 rev/min with a 42 mm ring diameter, where C-type half round travelers of 85 and 95 mg were employed in ring frames. The resulting 36 tex (αtex = 37.5) yarns were examined by measuring their tensile strength, elongation, count, twist, evenness, and hairiness. Then the yarns were knitted into fabrics to observe and evaluate pilling performance. The observations based on scanning electron microscope (SEM) images were concluded both on the hairiness and pilling values, depending on the blend proportions. Among the yarns produced, the best hairiness with the traveler of 95 mg weight was obtained from the blend yarn with a polyester/cotton ratio of 33/67 and the best pilling parameter was accrued from the knitted fabrics with a polyester/cotton ratio of 83/17.

Quality optimization of ring spun yarns produced from blends of regenerated cellulosic fibres with cotton and polyester

“…So it can be said that these all parameters explain the tenacity with the higher R square. Fibre blend ratio influenced yarn tenacity and this result is expected and reported from some other researchers [6,9,11,21]. The most effect size of independent parameters on tenacity is blend type with highest F value.…”

“…Blending of different kinds of fibres is widely used to reveal new alternative functional products and to improve the performance and the aesthetic qualities of yarns and fabrics [2]. Approximation of physical and mechanical properties of blended yarns has also been studied by various researchers [3][4][5][6][7][8]. There are various regenerated cellulosic fibre alternatives to enhance the performance of yarn and fabrics.…”

“…Bamboo can be spun alone or with the blend of other fibres such as rayon, cotton, wool, silk, modal, etc. with regard to the required quality of the products [3][4][5][6][7]. Bamboo fibre contributes the tenacity, thermal conductivity, resistivity to bacteria and high water and perspiration adsorption of textile products [17].…”

Blended Yarn Analysis: Part I—Influence of Blend Ratio and Break Draft on Mass Variation, Hairiness, and Physical Properties of 15 Tex PES/CO Blended Ring-Spun Yarn

“…R 2 value also reveals that CV% significantly depends upon fiber type from view point of P/C blended yarn. It is due to staple length and unvarying fineness of polyester fiber, which causes more evenness to the yarn in cross-section (Canoglu and Tanir 2009;Celik and Kadoglu 2009;Nawaz et al 1999;Temel & Celik 2010). Yarn imperfections are given in Table 3.…”

“…As the ratio of polyester in the blend increases, yarn tenacity, liveliness, and elongation increases whereas yarn hairiness diminishes; furthermore, yarn evenness becomes better with increase in polyester content (Celik & Kadoglu 2009;Canoglu and Tanir 2009;Nawaz et al 1999;Temel and Celik 2010). Uster irregularity also depends upon the material; cotton yarn has less U% than that of polyester while the blend lies in between (Balasubramanian and Nerurkar 1974).…”
