In this paper, we researched the technology of the shrink-resist finishjng of wool fabrics with the immobilized neutral proteinase, prcessed the single"actor experiment. The application technological parameter of the immobilized neutral proteinase was optimized by the orthogonal experimental design. The result showed that the amount of the immobilized neutral proteinase was 5 o/o ( owf), the treating temperature was 50 'C, the treating pH value was 7. 0 and the treating time was 60 min. The results finishing the wool fabrics with the free and immobilized neutral proteinase were compared. The result showed that the shrinkage effect was increased 37. 6%, the weight loss percentage was descended 45. 2%, the strength loss percentage was descended 52. 7%, the whiteness was increased 23. 2% and the anti-pill rate was raised by level 2. This will establish the basis of the industrializing enzyme on shrink-resist finishing of wool knitted fabrics. [ABSTRACT FROM AUTHOR] |
