毛织物用酶与纺织助剂的配伍性研究

Study of compatibility between enzyme and textile auxiliaries with wool

研究了毛织物防毡缩用碱性蛋白酶、中性蛋白酶与纺织助剂的配伍性能,通过相对活性法与减量法相结合,对无机助剂、表面活性剂和染料进行了研究,研究发现:Na+、K+、NH 4+、Mg2+、Ca2+盐低浓度时对酶具有激活作用;非离子型表面活性剂对酶具有激活作用;Cu2+、Fe3+、MnO 4-金属盐、离子型表面活性剂和染料对蛋白酶的活性具有明显的抑制作用;Na+、K+、NH 4+、Mg2+、Ca2+对中性蛋白酶的激活作用比碱性蛋白酶激活作用更显著,离子型表面活性剂和染料对碱性蛋白酶的抑制作用更为显著。这一研究对酶在毛纺工业上的应用可提供理论指导。

The article studied the compatibility between alkaline proteinase,neutral protease and textile auxiliaries with the wool finished.We analyzed the nonionic-organic textile auxiliaries,ionic-organic textile auxiliaries and dyes by reduction and relative activity combination method.The results showed that the salt of Na＋,K＋,NH＋4,Mg2＋,Ca2＋ promoted the catalytic of enzyme when the concentration of the salt was lower,the nonionic-surfactants could promot the catalytic of enzyme.The salt of Cu2＋、Fe3＋、MnO-4,ionic-surfactants and dyes could evidently restraint the catalytic of alkaline proteinase,neutral protease.The salt of Na＋,K＋,NH＋4,Mg2＋,Ca2＋ promoted more evidently the catalytic of neutral protease than alkaline proteinase.The ionic-surfactants and dyes restrainted more evidently the catalytic of alkaline proteinase than neutral protease.The studies might guide the application of protease for the wool textle industry on the theory.
