“…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.…”

Different blending ratios of Eri silk and cotton fibres were prepared. The optimum bleaching condition chosen for the blends containing 0-25% silk content was the oxidative bleaching method, whereas the blends at 50-100% should be bleached using the two-stage bleaching method (oxidative bleaching followed by reductive bleaching). These conditions did affect the force-displacement characteristics of the fibres with no yield point. X-Ray diffraction results showed that the percentage of crystallinity of the cotton yarn tended to increase after bleaching, whereas the percentage of crystallinity of the Eri yarn decreased marginally. Dyeing properties of the blended yarns were investigated using warm-dyeing reactive dyes. Percentage exhaustion and the colour yield of the blends tended to decrease with the increasing silk content. Shade variation was observed on the yarns at different blend ratios. This was expected to be caused by the different physical nature of Eri silk and cotton fibres. Consequently, the dye uptake and visual shade of each dye on the two fibres were different.

“…The drawframe blending and spinning processes of 30 and 50 yarn tex were carried out in the cotton spinning. Following preliminary laboratory scale processing, [1] it became apparent that the pure 100% Eri silk would require some kind of additive before satisfactory mechanical processing performances (especially in carding and drawing) could be obtained. Due to different humidity level from opening to drawing stages in the cotton spinning process (50-55%) compared to that in the spun silk process (65-80%) [8] , it needed to add some softeners (10-15%) in order to eliminate static electricity of Eri silk and to increase interfiber cohesion during processing.…”

“…Hence, it can only be used for raw material to blend with other fibers such as wool, cotton, polyester [1][2][3] in the cotton-like spinning. In Thailand, Eri silk culture has been carried out only in research using feeds such as castor and cassava leaf.…”

“…[5][6] For the previous study of the Eri silk and cotton blending at the ratio of 50/50 in cotton spinning, it was found that the intimate blending and the drawframe blending resulted in no significant difference in the physical properties of their blends. [1] So in this study, the drawframe blending was chosen due to easy control of the weight ratios of silk and cotton fibers. The two factors of silk contents (0-100%, factor A) and yarn counts (30 and 50 tex, factor B) were studied their influence on yarn and fabric characteristics.…”

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.

“…3 In the past, both of these methods had been frequently applied on a variety of yarns to understand the fiber arrangement inside them and establish its effect on the physical characteristics (or quality) of yarns. [4][5][6][7][8][9] In addition, various developments in both of these methods were also proposed, ranging from improvements in experimental setup to automated image analysis of tracer fibers and yarn cross-sectional images. [10][11][12][13][14][15] The ultimate goal of these efforts was to improve yarn quality by understanding and manipulating the yarn structure.…”

The micro-level structure of staple yarn and the fiber arrangement inside it has a decisive influence on its physical properties. This study aims to introduce a combined method based on micro computerized tomography (micro CT) and digital image processing techniques to probe the ring yarn structure in a non-invasive manner. Two micro CT systems at different CT settings were applied to achieve optimal quality CT images of cotton ring yarns. Three image processing algorithms were proposed to enhance and process the yarn CT images in order to extract yarn structural information. The proposed method was also applied on two yarn specimens, which varied significantly in terms of their tensile strength, to study differences in their underlying structures. The results showed that the longitudinal arrangement of fibers in terms of their migratory behavior had a decisive influence on the tensile properties of the yarn. The stronger yarn showed a higher value of the amplitude and intensity of fiber migration compared to the weaker yarn, suggesting that the protocol established in this study can effectively reveal fiber arrangements within a staple yarn structure in a non-invasive manner.
