Abstract
In order to develop new shrink-resistance finishing by using enzyme, the promoting effect of surfactants on enzyme treatment of wool was studied. Wool fabric was pretreated with anionic surfactants. This pretreatment accelerates the following enzyme treatment remarkably, and high weight loss values over 30% were obtained within 3hours. The typical anionic surfactants, fatty acid sodium salts and sodium dodecyl sulfate (SDS) show the different promoting effects, respectively. Oleic acid sodium salt works in the center of wool fiber, and hydrolyzes the cell membrane complex in cortex. The other hand, SDS works in the scale on the wool surface. The SDS depresses the fibrillation of wool fiber and improves fiber strength.
