乌拉草/棉纱线性能的模糊综合评价

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

为了综合评价乌拉草(Carex meyeriana)/棉纤维混纺比对纱线性能的影响,以利于乌拉草在纺织服装上的应用。本研究以纱线断裂强度、断裂伸长率、毛羽、条干、细结、粗结、棉结为性能评价指标,采用模糊综合评价方法对乌拉草/棉纤维质量配比为12/88、25/75、37/63、46/54的4种不同混纺比纱线性能进行了综合评价。结果表明,模糊综合评价得到4种混纺比的隶属度分别为0.370 5、0.238 6、0.210 4和0.180 5,即乌拉草纤维的含量越低,纱线的综合性能越优,所以4种不同质量配比中12/88的乌拉草/棉混纺纱性能最优,且试验得到25/75、37/63的乌拉草/棉混纺纱性能接近。因此对于不同的要求,可以选择不同的乌拉草/棉混纺比,试验结果为乌拉草纤维在纺织服装上的应用提供了依据。

To comprehensively evaluate the influence of different ratios of Carex meyeriana and cotton on yarn properties and encourage the C.meyerianato 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.meyerianaand 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 were0.370 5,0.238 6,0.210 4,and 0.180 5,respectively.indicating that lower C.meyerianacontent 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.meyerianafibers＇ application in textile garments.
