摘要
采用碱液、超高温和自制柔软剂处理研制高性能丝绵.通过碱液浓度、柔软剂浓度、超高温处理时间和柔软剂处理时间的正交试验设计,对相关指标进行DPS数据分析,发现4因素对丝绵的弹性回复率没有显著的影响,而柔软剂对弹性压缩率和含油率均有显著影响.丝绵的弹性回复率为92.37%～97.66%,弹性压缩率为59.21%～66.77%,均优于行业标准蚕丝绵被特级品的规定.丝绵的含油率为0.28%～1.39%,均优于行业标准蚕丝绵被一级品的规定.丝绵的平均保温率在81.91%～85.24%之间,传热系数的平均值在21.37～27.13 W/（m^2·℃）之间.超高温蒸汽处理有利于增加丝绵的弹性和蓬松性.提出了丝绵加工比较适宜的工艺条件组合.
A high performance floss silk was prepared by means of combination treatments of lye, extra high temperature and softener prepared by researchers themselves. Concentrations of lye and softener, treating time under extra high temperature and treating time with softener were used as factors in orthogonal experiments and the data were analyzed by DPS. And it was found that these factors have no significant influence on the elastic recovery percentage of the floss silk, whereas the softener has significant influence on its compression ratio and oil content. The elastic recovery percentage of the treated floss silk is 92.37 % - 97.66 % and the compression ratio, 59.21% - 66.77%, both are superior to the criteria set by the textile industry for the superfine wadding floss silk. Its oil content is 0.28% -1.39%. The average warmth retention rate is 81.91% - 85.24% and average thermal transmittance coefficient, 21.37 - 27.13 W/（m^2 ℃ ）. Treatment with extra high temperature steam is beneficial to the elasticity and loftiness of floss silk. Suitable processing techniques for floss silk are given.
