Fuzzy and comprehensive evaluation on performance of blended yarn with different ratios of Carex meyeriana and cotton

To comprehensively evaluate the influence of different ratios of Carex meyeriana and cotton on yarn properties and encourage the C. meyeriana to applicate textile garments, this study used the method of fuzzy and comprehensive evaluation to evaluate the yarn properties of 12/88, 25/75, 37/63, 46/54 ratios of C. meyeriana and cotton by measuring the fracture strength, elongation at break, hairiness, the evenness, knots, slubs, neps. The results of this study showed that the membership degrees of four different blended ratios were 0.370 5, 0.238 6, 0.210 4, and 0.180 5, respectively. indicating that lower C. meyeriana content was beneficial to the yarn’s comprehensive performances, in which the yarn properties of C. meyeriana/cotton 12/88 was the best in the four different blended ratios. The yarn properties of 25/75, 37/63 blended ratios were similar. Different C. meyeriana/cotton blended ratio could be chosen with the different demands. These results provide the basis for C. meyeriana fibers’ application in textile garments.
