Abstract

The invention discloses a fabric finishing method with self-adaptive air permeability, and belongs to the technical field of functional textile processing. Firstly, introducing vinyl on the surface of the fabric by virtue of reaction of methacrylic anhydride and hydroxyl on the fiber; secondly, padding the fabric in a mixed solution of hydroxyl boron nitride and a temperature-sensitive monomer N-isopropylacrylamide; and finally, catalyzing graft polymerization of N-isopropylacrylamide and the fabric by virtue of horse radish peroxidase, and carrying out air permeability self-adaptive fabric finishing. Comprising the following steps: (1) vinylating the surface of the fabric; (2) padding the fabric with a temperature-sensitive monomer; and (3) carrying out enzymatic graft polymerization on the temperature-sensitive monomer. Compared with a conventional chemical grafting modification finishing method, the method has the advantages that the breathable self-adaptive effect is remarkable, the reaction condition is mild, and the finishing effect is lasting.

Description

technical field [0001] The invention relates to an air permeability adaptive fabric finishing method, which belongs to the technical field of functional textile processing. Background technique [0002] The warmth and breathability of fabrics are related to the yarn thickness and structural tightness of the fabric. Generally speaking, the thicker the yarn of the fabric and the higher the structural tightness, the better the warmth retention and the poorer the air permeability of the fabric; on the contrary, when the yarn is thinner and the structural tightness of the fabric is lower, the Warmth decreases and breathability increases. Therefore, clothing fabrics of different specifications have different wearing characteristics, which mainly depend on the above-mentioned fabric structure characteristics. [0003] In the process of wearing clothing fabrics, when the outside temperature conditions change, there are also different requirements for the fabric's warmth retention ...
