Abstract
Disclosed is a shape memory polyamide, produced by adding a polyvalent carboxylic acid and a polyvalent amine when polyamide is polymerized from e-caprolactam or hexamethylenediamine and adipic acid, and having an aromatic component which is introduced by one or more among the polyvalent carboxylic acid and the polyvalent amine and has a total amount ranging from 0.4 mol % to 10 mol % based on the amount of the raw material for polyamide. Also, a method of producing a shape memory polyamide fabric using the shape memory polyamide is provided. The polyamide fabric produced using the shape memory polyamide is a highly functional fabric which does not easily wrinkle and easily recovers its original shape even when wrinkled, and thus may be applied as material for various kinds of clothing.
