Effect of Blending Factors on Eri Silk and Cotton Blended Yarn and Fabric Characteristics

Abstract

Summary: Eri cocoons were prepared into short fibers and subsequently blended with cotton fiber in order to develop the new fiber blended yarn in the short spinning system. The Eri and cotton fibers were blended using the drawframe blending with varying blending factors, viz. blending composition (0-100%) and yarn counts (30 and 50 tex). The results showed that Eri fiber which was longer and stronger than cotton fiber, affected the fiber distribution in the yarn cross-section. The mechanical properties of the blended fibers and yarns increased with increasing silk content. Longer fibers of Eri silk tended to move towards the yarn core, especially at silk content higher than 50%. Moreover, stronger and more extensible Eri silk fiber gave an advantage to the improvement of mechanical properties of those blended yarns with silk content higher than 50%. However, with increasing silk content, the blended yarns were more irregular as shown in %CV. Concerning the yarn count effect, the higher yarn count of 50 tex resulted in a more regular yarn with higher yarn strength than that of 30 tex. The plain-woven fabrics were prepared using the blended yarns as a weft yarn and the cotton yarn or silk yarn as a warp yarn. The mechanical properties of those woven fabrics were characterized in order to study the influence of silk contents. The results showed that tensile strength, %elongation and tear strength of woven fabrics using the blended yarn were increased with an increase in silk content. This is an advantage of Eri silk in the aspect of rendering the strength to the blended yarns and fabrics.

Influence of Eri silk fibre on the physical characteristics and dyeing properties of Eri silk/cotton blended yarn

“…Effect of bleaching on the physical properties of the blended yarns From the previous results [10], the physical properties of the blended yarn after peroxide bleaching were varied depending on the fibre blend ratios. Because of the different fibre lengths, finenesses and strengths between Eri silk and cotton, their fibre distribution at different ratios provided different physical properties [8,16]. In this study, the colour (L* and whiteness) ( Figure 1) and mechanical properties ( Figure 2) of the blended yarn after bleaching under different conditions were investigated.…”

“…To date, a few research articles have been published on the structure and mechanical properties of wild silk fibre, especially Eri silk fibre [4][5][6][7][8]. A previous study of Eri silk ⁄ cotton blending has been reported about the effect of fibre properties, the blending process and fibre migration on the physical properties of the blended yarn [7,8].…”

Farklı Doğal Liflerin İç Giysilerde Kullanımının Konfor Özellikleri Açısından Araştırılması

“…Yapılan detaylı incelemelerde ipek liflerinin iç giysilerde kullanılmasına dair kapsamlı bir çalışmaya rastlanamamıştır. Araştırmacılar, daha çok ipek liflerinin eğrilmesi konusuna odaklanmışlardır [11][12][13][14][15][16][17][18] ısıl temas özellikleri ıslak ve kuru şartlarda incelenmiştir. İlk temas anındaki ısıl özellikler üzerinde şardonlama işleminin, iplik tipi ve lif karışımından daha önemli olduğunu vurgulamışlardır [22].…”

Structure-Property Relation between Non-Mulberry Silk Fabrics and Goat Suede Leather

“…The stress-elongation behavior of mulberry and non-mulberry silk fibers have been compared by Kothari et al [17]. Chollakup et al have studied the effect of blending eri silk with cotton fibers and found that the tensile properties of the woven fabrics were improved with the increase in silk content [18]. In this study, we have chosen muga, eri and their blend silk fabrics for possible combination with leather for making various life style products including clothing.…”
