| The pretreatment of wool fibers with chymotrypsin was researched,then the pretreated wool was dyed with acid scarlet BS in low temperature dyeing process,the dye uptake,K/S value and breaking strength of dyeing wool were determined.The results of experiment expressed that,in the pretreatment conditions of 2%(owf)chymotrypsin,pH=7,40 ℃ and 60min,the wool was dyed with acid scarlet BS at 80 ℃ to get 95.1% of dye uptake,15.05 of K/S,5.78% lose of breaking strength.Compared with Conventional process,both of the dye uptake and K/S value had increased while the lose of breaking strength was less. |
