A shape memory processing agent is composed of cysteine and cysteamine in proportion of 1:1 that provides a shape memory characteristic to a animal fiber product. At this time, in case it is under 1:1, the reduction force is weak that is unfavorable for a wrinkle formation, causing a white crystal to be generated, in case the proportion is over 1:5, a wrinkle formation is strong, but a stain is formed. And a protective agent, a wetting agent, an antioxidant, etc. are added, then, even in the low concentration, the shape memory offering function for the animal fiber product is provided
