Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of textile fabric finishing, and particularly relates to a processing method of super-comfortable natural wrinkle-resistant fabric. BACKGROUND

[0002] With the acceleration of modern life, consumers prefer clothes that are easy to care for and have natural touch. Most of the current wrinkle-resistant shirts are achieved through chemical wrinkle-resistant finishing of fabric or chemical wrinkle-resistant finishing of garments, which has the risk of releasing formaldehyde and high use of additives to pollute the environment. At the same time, the chemical wrinkle-resistant fabric has poor touch and poor wearing experience.

[0003] Patent CN103541103A discloses that the wrinkle-resistant effect is improved by changing the conventional specifications and dyeing depth of the fabric, without chemical wrinkle-resistant finishing. The flatness of the fabric after washing is about 3.0 level, and the fabric still needs to be ironed after washing, which cannot meet the demand of people for high wrinkle resistance. Patent CN119041073B discloses that the natural high wrinkle-resistant performance is achieved by using the wrinkle-resistant performance of the fiber itself, the rigidity of high-twist yarn, and the low bending degree of yarn in the fabric and the change of fiber morphology by liquid ammonia molecules. The high-twist yarn will affect the touch of the fabric, and is more suitable for spring and summer seasons, and the application scene is limited, which cannot meet the demand of four seasons. In addition, the high-twist yarn process is complex and difficult to produce. Therefore, it is urgent to develop a formaldehyde-free super-comfortable natural wrinkle-resistant product. SUMMARY

[0004] The purpose of the present application is to provide a processing method of super-comfortable natural wrinkle-resistant fabric.

The fabric realizes wrinkle resistance of 3.5 level and above, has a layer of short and dense nap on the surface, has delicate hand feeling, comfortable wearing, easy care, zero formaldehyde content, and is more environmentally friendly and healthy.
