The Effect of Blending Ratio and Yarn Twist Multiplier on Polysulfone /Meta-Aramid Blended Yarn Properties
The effect of blending ratio and yarn twist multiplier on Polysulfone /Meta-aramid blended yarn properties is studied. Two-factor analysis of variance shows that yarn twist multiplier and blending ration have a significant effect on yarn breaking strength while yarn breaking elongation is affected by yarn twist multiplier considerably. Yarn evenness varies with blending ration delicately. Blending ratio and yarn twist multiplier have little effect on yarn hairiness. Yarn evenness nearly has no change with yarn twist multiplier and yarn breaking elongation remains consistent under different blending ratios. Yarn breaking strength gets higher with Meta-aramid content increasing. When the yarn twist multiplier is small, it’s easy to increase yarn strength by blending high-strength fibers. Yarn breaking elongation gets higher when yarn twist multiplier is larger. Blended yarn evenness gets better with finer Meta-aramid content increasing.
