摘　　要：以硫化钠(Na2S)为主溶剂,尿素为变性剂,十二烷基硫酸钠(SDS)为稳定剂,在一定条件下对羊毛进行溶解。探讨了3种试剂的不同用量对羊毛溶解的影响。结果表明:Na2S用量对羊毛的溶解影响最大,随着用量的增加,羊毛溶解率和所得溶液的黏度不断增加,当用量达到3%,羊毛的溶解率和溶液的黏度均达到最大。当尿素浓度为7 mol/L时,羊毛的溶解率达到最大,但溶液的黏度却随着尿素用量的增加而不断增大。SDS用量对羊毛溶解率的影响不大,主要是对溶液黏度有影响,当用量为1.0%时,溶液黏度最大。所以只要合理组合这3种溶剂就能很好地溶解羊毛,文章为正确选择羊毛角蛋白溶解工艺提供了依据。In order to research the effects of sodium sulfide solvent system on the dissolution of wool fibre,the dissolution was conducted under certain conditions. The sodium sulfide solvent system was composed by sodium sulfide,urea and sodium dodecyl sulfate（SDS） in which the sodium sulfide was main solvent,urea was denaturant and sodium dodecyl sulfate（SDS） was stabilizer. The different dosages of the three reagents on the dissolution of wool fibre were investigated. The results indicated that the dissolution of wool fiber was mostly afftected by dosage of Na2 S. With its dosage increasing,the dissolving rate of wool fibre and the viscosity of solution increased. When its dosage reacheed 3%,the dissolving rate of wool fibre and the viscostity of solution were both maximum. Followed by the amount of urea,when its oncentration was 7 mol/L,the dissolving rate of wool fibre reached the maxmium. But the viscosity of solution increased with the increase of urea concentration. The amount of SDS had little effect on the dissolving rate of wool fiber,which mainly affected the viscosity of solution. When the dosage was1%,the solution had the maximum viscosity. So as long as the three solvents are reasonable combination,the wool fibre can be well dissolved,which provides a basis for the correct selection of wool keratin solution process.
