Investigation of the concurrent sliver-opening mechanism and unveiling features of the new dual-feed rotor spinning concept

To examine the effectiveness of the new dual-feed rotor spinning system, we performed a set of experiments to assess the influence of the opening roller type, sliver feed method, and direction of fiber feeding into the rotor on the quality of a polyester/cotton blend yarn. Six yarn samples of 58tex consisting of 55/45 polyester/cotton were prepared in this study. Their respective properties, such as tenacity, elongation at break, mass irregularity, hairiness, thick (+35%) and thin (?30%) places were tested and statistically analyzed using Minitab. ANOVA analysis showed that the tested yarn quality properties were statistically significant among groups except for thick places (+35%). Tukey’s post hoc test based on the honest significant difference was performed to determine the implication of results within groups at the value of α?=?0.05. The dual-feed blend yarn (PCLR) spun with opening roller type OK37 on the left and OK40 on the right exhibited superior yarn quality characteristics compared to other samples. Dually carded slivers yielded better yarn quality compared to simultaneously carded ones. The combing direction did not produce a clear trend on the quality of yarns. The study provides important insights into the potential of the dual-feed rotor spinning concept.

A study on the suitability of which yarn number to use for recycle polyester fiber

Recycling and reuse of materials is not new to the textile and apparel industry. Recycling refers to the breakdown of product into its raw materials in order for the raw material to be reclaimed and used in new products. The aim of the study is that the examining the usage of recycle polyester fiber (rPET) in different yarn count and blend ratio and so to determine which count and blend ratio is more suitable for rPET usage. For this aim, 24 yarns containing recycle polyester fiber, virgin polyester fiber and viscose fiber as raw material were obtained in different yarn counts which are Ne 10, Ne 20, Ne 30 and Ne 40, and in different blend ratios. Yarn diameter, density, shape (roundness), unevenness, imperfection, hairiness, and yarn tensile tests were applied to the obtained yarns. The findings obtained by experimental and statistical study show that rPET fiber has usually negative effects on the yarn properties in especially fine yarns due to physical and chemical deterioration caused by contaminants of during re-processing of recycle polyester fiber. Based on the findings it is revealed that the values of unevenness, imperfection, and density increase whereas the values of diameter, hairiness, and tensile decrease from coarse yarns to fine yarns. As a conclusion it is possible to say that rPET fiber is suitable for thick yarns which are especially Ne 10 and Ne 20 as pure and in all blend ratios, and rPET fiber is suitable if it is used in lower ratios than 65% for Ne 30 yarns, whereas it is suitable if it is used in lower ratios than 35% for Ne 40 yarns.

Potentiality of Indian pineapple leaf fiber for apparels

The use of textile-grade fiber extracted from the Indian pineapple leaf is an unexplored area. Pineapple leaf fiber (PALF) is fine, soft, and moderately strong and is much acceptable for fashion garment. An attempt has been made to extract and soften Indian PALF from the pineapple leaves by decortication and subsequent water retting. Decorticated cum retted fiber has shown better physicomechanical and surface appearance properties than decorticated fiber. Fine yarn (38 tex) was spun in a suitable spinning system, and the property performance was found to be suitable to make eco-sustainable novelty fabric. Fabric was developed by using cotton as warp yarn and PALF-based yarn as weft in a handloom. The developed fabric shows very good physical and mechanical properties, desired for apparels. This inferred that Indian PALF may be successfully used to make eco-niche apparel quality fabric as well as novelty textiles.
