摘要
以化学预处理工艺中的亚硫酸氢钠质量分数、硫酸铵质量分数、水浴温度和预处理时间为影响因子,设计正交实验,以预处理后羊驼毛的断裂伸长率和断裂强度为测试指标,得出羊驼毛拉伸细化预处理的最优工艺:亚硫酸氢钠的质量分数8%,硫酸铵的质量分数6%,水浴温度75℃,预处理时间15 min。
The article set the solution recipe, the concentration of solution, the solution temperature and pre-treat time of chemical pretreatment process as the factors of the orthogonal test to design the test method which according to the factor and the level of the test.The best process is achieved, the concentration of NaHSO3 is 8%, the concentration of （ NH4） 2SO4 is 1%, temperature is 75 ℃, pretreatment time is 15 min.
