Purpose

As one natural fiber, yak cashmere has been used more and more widely on textile processing due to its excellent warmth retention property. Yarn spinning is the first and the most important step of textile processing. Yarn spinning is closely related to the fiber properties. That is, for giving the optimization spinning process of one new fiber, the properties of the new fiber should be studied firstly. Meanwhile, during the studying of the properties of the new fiber, comparative analysis method was usually used. That is, the property of the new fiber was common comparatively analyzed with other fibers. During the comparative analysis, the spinning process can be optimized. Therefore, in the paper, the properties of the yak cashmere were studied in detail and comparatively analyzed.

Design/methodology/approach

The brown yak cashmere, cyan yak cashmere, white cashmere fiber, purple cashmere fiber, cyan cashmere fiber, camel hair fiber and mohair fiber, were chosen as the samples. The fiber length, fineness, strength, curls, moisture regain, mass specific resistance, surface morphology, infrared spectrum, melting behavior, thermal weight loss, friction, x-ray, were tested and comparatively analyzed.

Findings

It is shown that the compositions of yak cashmere and cashmere are similar, and makes the physical properties of yak cashmere and cashmere fiber similar. Comparing with the mohair, camel hair and cashmere fiber, the average length of yak cashmere is smaller and the dispersion of length distribution is larger, and the dispersion of yak cashmere strength is larger, which makes the yarn spinning of yak cashmere difficult, especially the high count pure yarn. However, comparing with the mohair, camel hair and cashmere fiber, the friction coefficient and friction effect of yak cashmere is larger, and yak cashmere fiber has relatively less curls and larger crimp rate and crimp recovery rate, and can improve the fiber spinnability.

Originality/value

In the paper, taking the brown yak cashmere, cyan yak cashmere, white cashmere fiber, purple cashmere fiber, cyan cashmere fiber, camel hair fiber, mohair fibers as the samples, the properties of the yak cashmere were studied in detail. The fiber length, fineness, strength, curls, moisture regain, mass specific resistance, surface morphology, infrared spectrum, melting behavior, thermal weight loss, friction, x-ray, were tested and comparatively analyzed. The studies can establish foundation for the optimization of the yak cashmere spinning process, and also can provide information for the end uses of the fiber.

牦牛绒纤维性能研究

目的

牦牛绒作为一种天然纤维，由于其优良的保暖性，在纺织加工中得到越来越广泛的应用。纺纱是纺织加工的第一步，也是最重要的一步。纱线的纺纱与纤维的性能密切相关。即为优化一种新纤维的纺丝工艺，首先要研究新纤维的性能。同时，在研究新型纤维的性能时，通常采用比较分析的方法。即，新纤维的性能通常与其他纤维进行比较分析。通过对比分析，可以优化纺纱工艺。因此，本文对牦牛绒的性能进行了详细的研究和对比分析。

设计/方法/方法

选择棕色牦牛绒、青色牦牛绒、白色羊绒纤维、紫色羊绒纤维、青色羊绒纤维、驼毛纤维和马海毛纤维作为样品。对纤维长度、细度、强度、卷曲度、回潮率、质量比电阻、表面形貌、红外光谱、熔融行为、热失重、摩擦、X射线等进行了测试和比较分析。

发现

表明牦牛绒和羊绒的成分相似，使得牦牛绒和羊绒纤维的物理性能相似。与马海毛、驼绒和羊绒纤维相比，牦牛绒的平均长度较小，长度分布的离散度较大，牦牛绒强度的离散度较大，这使得牦牛绒的纱线纺纱困难，尤其是高支纯纱。但与马海毛、驼毛和羊绒纤维相比，牦牛羊绒的摩擦系数和摩擦效果更大，而牦牛羊绒纤维的卷曲相对较少，卷曲率和卷曲恢复率较大，可以提高纤维的可纺性。

原创性/价值

文中以棕色牦牛绒、青色牦牛绒、白绒绒、紫绒绒、青绒绒、驼绒绒、马海毛绒为样品，对牦牛绒的性能进行了详细的研究。对纤维长度、细度、强度、卷曲度、回潮率、质量比电阻、表面形貌、红外光谱、熔融行为、热失重、摩擦、X射线等进行了测试和比较分析。该研究可为牦牛绒纺纱工艺的优化奠定基础，也可为纤维的最终用途提供信息。
