摘要
选用还原剂TCEP(三羧乙基膦)作为打开二硫键的试剂,与酸性蛋白酶同浴处理羊毛。采用正交法设计酸性蛋白酶羊毛细化改性试验方案,确定了主要影响因素及水平。实验结果表明:影响羊毛强力和细度的主要因素是TCEP与蛋白酶的用量,而pH值与时间对细度与强力的影响不大。最佳处理工艺为:TCEP用量2%(owf),酸性蛋白酶用量2%(owf),50℃处理90 min。经过该工艺处理后的66支国产羊毛,细度下降1.393μm,强力保留71.2%。
This paper chooses reductant TCEP（Tris（2-carboxyethyl） phosphine） as a reagent of damage the disulfide bond,and joint use of acid protease one-bath method to deal with wool.Using orthogonal design acid enzyme wool thining modification experiment,to determine the main influence factors and levels.The experimental results show that the main impact of strength and wool fineness is the dosage of TCEP and acid protease.The pH value and time have little effect to the strength and fineness.The best process is 2%（owf） of TCEP and 2%（owf） acid protease,and dealed with 90 min.The 66s domestic wool is treated by this process,the fineness falled by 1.393μm and the strength reserved 71.2%.
