水解法制备高吸水腈纶正交实验

Orithogonal Experiments of Preparing High Drinking Acrylic Fibers Through Hydrolisis

对腈纶纤维的水解工艺进行研究 .正交实验结果表明 ,实验范围内 ,水解时间是影响腈纶纤维吸水率的关键因素 ,随着时间的延长 ,吸水率增加 ;水解温度 80℃时吸水率较高 ;NaOH浓度对水解腈纶的吸水率也产生较大的影响 .温度。

Hydrolization technology on acrylic fibers is investigated. Orthogonal experiment results show that hydrolization time is the key factor, which affects drinking rate of acrylic fibers. In the range of experiments, NaOH density also has a bigger effect on drinking rate of hydrolization acrylic fibers. Temperature, time and NaOH density have an effect on the whiteness of acrylic fibers.
