Detergent action as applied to textiles is remarkably dependent on the removal of soil and the prevention of redeposition of this soil. The more soil removed, the more preventive redeposition proceeds, we can get cleaner textiles. It is presumed that little is formerly guided about the mechanism on detergent action relating to the redeposition of soil, in estimating the contents of textbooks and guidelines for teaching on "General Home Economics" and "Clothing" of senior high schools. In order to develop an instructional material on detergent action with anti-redeposition agent in homemaking education, we introduce a water-soluble polymer, poly-ethylene glycol (PEG), as one of anti-redeposition agent. By the help of instructional materials emphasizing the redeposition of soil, students will be able to learn detergent action effectively.
