Effect of Different Blend Ratios of Natural Fibers on Yarn Properties

Abstract

Yarn construction is an important attribute in fabric construction and end use performance of fabric. The purpose of this study was to investigate the effect of different blend ratio of natural fibers, on yarn properties. Four different fibers such as Bamboo regenerated fiber, cotton, flax, and hemp were used at different blend ratios to manufacture ring spun 16/1 yarns with TM of 4.0. Blend ratios of bamboo regenerated fiber was kept 100%, 90 %, 80 % and 70 % while blend ratios of cotton, flax and hemp were adjusted at 10 %, 20 % and 30 %. Thus, total of ten yarn samples were prepared for this study. Different properties of these yarns such as linear density, lea strength, clsp, tensile properties, unevenness, imperfections, and hairiness, were determined as per standard test methods.Analysis of the collected data shows a significant effect of blend change on all yarn properties. It may be concluded that blends of bamboo regenerated fibers with cotton displayed best results as compared to blends with flax and hemp. Another trend may also be revealed that yarn quality improved as ratio of cotton changed from 10 % to 30 % while degraded as ratio of flax and hemp is changed from 10 % to 30%.
