Studies on the Decrement Treatment of Wool Textile by Acid Protease Degradation Coupling with KMnO4 Oxidation

Anew technique for decrement treatment of wool textile was carried out by acid protease degradation coupling with KMnO4 oxidation. Experimental results indicated that the optimum conditions were KMnO4 59% (o. w. f), penetrating agent 200g/L, pH = 3, 50℃ ,bath ratio 1: 30,oxidation treated for 1 hour,Then adding acid protease in and making its final concentration 15μ/mi, NaHSO3 6% (o. w. f),pH= 3,50℃ ,bath ratio 1: 30,degradailon treated for 45min; finally raising the temperature to 80℃ so as to deactivate and washing,drying of wool textile. Under these optimum conditions, the decrement rate of wool textile was about 8.496 .softness and strength were highly acceptable
