Abstract
Study on the use of enzymes for textile wet processing has been very active. The exploratory research conducted herein is related to the bioscouring process for cotton fabric. The optimum concentration of alkaline pectinase(BioPrep) was in the range of 0.05～0.2 g/l, the proper treatment time was 30～60 minutes, the appropriate treatment temperature was $60^{\circ}C$ for both the batch method and the padding method. The simultaneous desizing/bioscouring by padding method did not give water absorbency as good as the bioscouring after desizing. Color of fabrics which were bioscoured and dyed with direct dyes and a reactive dye was just a little darker than that of NaOH scoured one. K/S and Lab values of the bioscoured fabrics, regardless of the degree of water absorbency, were quite similar to each other.
