超细羊毛低损伤梳毛加工技术

为解决13.0 μm以下的超细羊毛加工困难和梳理损伤严重的问题，提高其使用价值，对梳毛损伤进行成因分析并探讨解决办法。通过对梳毛各工作区的纤维长度、毛粒数、落毛率的测定，利用TEAM-3预测公式和正交试验法，优化各工艺参数，确定了隔距、速比、锡林针布齿密、道夫针布齿密、出条重量等梳毛工艺的最优配置条件，其中2#隔距、3#速比，针布规格为60.7 齿/cm2锡林针布齿密，道夫针布齿密为62.5 齿/cm2，出条重量为20 g/m。经过验证，利用此低损伤梳毛工艺制成的超细羊毛精梳毛条，纤维长度平均损伤小于0.5 mm，毛粒减少，条干明显改善。

Low-damage carding technology of superfine wool

In order to solve the problems of difficulty processing and carding damage of the superfine wool, the paper analyzed the causes and solutions to thecarding damage. Through the measurement of fiber length, the number of neps, noil ratio in work space of combing, the carding process parameters were optimized, the optimal carding processing conditions were determined by TEAM-3 and orthogonal experiments as following: 2# gauge, 3# speed ratio, the tooth density of cylinder wire cloth and doffer wire cloth was 60.7 teeth/cm2 and 62.5 teeth/cm2, respectively, and top produced was 20g/m. The experimental results showed that the average loss of fiber length of the superfine wool tops derived from the optimal processing wasless than 0.5 mm. The number of neps was also decreased and yarn quality was improved.
