Description

Technical Field

[0001] The invention belongs to the technical field of fabrics and relates to a light and thin wrinkle-resistant fabric and a preparation process thereof. Background Art

[0002] Common methods for increasing the wrinkle resistance of fiber fabrics include impregnation finishing, heat setting treatment, high-density weaving, ultrafine spinning process and mechanical calendering treatment. Among them, impregnation finishing is usually used in combination with high-density weaving to achieve better wrinkle resistance for fiber fabrics. Impregnation finishing refers to coating a special chemical agent, such as a polymer or resin, on the surface of the fiber fabric to form a protective layer to enhance the wrinkle resistance of the fiber fabric and improve its wear resistance. However, the impregnation finishing in the existing process is only to simply coat the polymer or resin on the fiber fabric, or to add a compatibilizer to increase the adhesion of the two. The fabrics produced by this process usually become hard and wrinkle easily after multiple washings. The reason may be that the compatibilizer is lost due to multiple washings and the polymer or resin is worn and detached. It is necessary to propose a preparation process to solve this problem.
