Qualitative and statistical analysis of cotton-flax blend yarn

Purely cotton fabric lacks different functional and physical properties than cotton-flax blends fabric. The experimental part of the present study is to investigate the influence of flax fibres content in cotton-flax blended yarn quality. Five ring yarn samples of the same count, 16/1Ne but from different blend ratios (100C, 80C:20F, 70C:30F, 45C:55F, and 100F) were produced from the same spinning preparatory conditions. The primary outcome was measured by analyzing test results obtained from different testing instruments (Uster Evenness tester, Mesdan Tensile Tester, and Instron Lea strength tester). The secondary outcome was measured by statistical analysis. Evenness properties were better for 80:20 blends in CVm% (17.13), IPI (1346), and H (6.89). 100% cotton yarn possessed the richest evenness quality CVm% (13.23), IPI (168.4), and H (7.97) in contrast to the poorest result of 100% flax yarn. On the other hand, the highest strength (CSP 4631, RKM 30.22) and the lowest elongation, 2.29%, were both achieved for 100% flax yarn. Evenness properties and elongation deteriorated with the gradual increase in flax content. In terms of strength, tenacity and CSP both decreased with an increase in flax content, but 100% flax yarn exhibited the highest performance.
