摘要
为了改善兔毛纤维的可纺性,拓展兔毛在纺织领域的应用,对经过选培、提纯的蒙阴县新型改良兔毛进行形貌特征分析,并测试其力学性能、摩擦性能和卷曲性能.结果表明,改良兔毛的鳞片层变薄,鳞片向外凸起的程度减小,鳞片不再有明显的重叠,纤维整体变得更加光滑;改良兔毛的长度为 93.00 mm,相较于长度为64.89 mm的普通兔毛,增加了 43.32%;平均强度达到 16.11 cN/tex,比强度为 14.97 cN/tex的普通兔毛有一定幅度的提升;与卷曲数为 8.1 个/(25 mm)的普通兔毛相比,改良兔毛卷曲数为 11.3 个/(25 mm),增加了 39.5%;改良兔毛纤维顺、逆鳞片方向的摩擦因数下降,定向摩擦效应减弱,提高了兔毛纤维的防毡缩性能.
Abstract
In order to improve the spinnability of rabbit hair fiber and expand the application of rabbit hair in different fields,a new-type improved rabbit hair in Mengyin County was analyzed by morphology features,and its mechanical properties,friction properties and curling properties were tested.The results show that the scale layer of the improved rabbit hair became thinner,the degree of scale outward projection decreased,the scales had no obvious overlap and the fiber got smoother;the length of the improved rabbit hair was 93.00 mm increased by 43.32%compared with the length of ordinary rabbit hair of 64.89 mm;the average strength reached 16.11 cN/tex which was somewhat improved compared with 14.97 cN/tex of the ordinary rabbit hair.Compared with the ordinary rabbit hair with 8.1 curls/(25 mm),the improved rabbit hair had 11.3 curls/(25 mm),which was 39.5%higher.The friction factors of the fibers in the downward and backward scale directions were decreased,and the effect of directional friction was weakened,so that the antifelting and shrinkage properties of rabbit hair fibers were improved.
