Abstract

The invention provides a crease resistant finishing agent for cotton fabric and a crease resistant finishing method, and relates to the technical field of garment fabric finishing. The crease resistant finishing agent for the cotton fabric is prepared from the following raw materials in parts by weight: 6-13 parts of butanetetracarboxylic acid, 3-7 parts of pyromellitic dianhydride, 3-6 parts of ethylenediamine tetraacetic acid, 3-7 parts of chitosan, 0.005-0.03 part of nano dioxide, 0.3-0.6 part of silane coupling agent, 4-8 parts of softening agent, 6-10.5 parts of sodium hypophosphite, 3-8parts of polyethylene glycol 500, 30-60 parts of propylene glycol and 1000 parts of water. Under the condition that a small amount of butanetetracarboxylic acid and sodium hypophosphite are used, thecotton fabric can be endowed with excellent comprehensive performance and is good in crease resistant effect, large in recovery angle, high in tear strength retention rate and good in whiteness.

Description

technical field [0001] The invention relates to the technical field of clothing fabric finishing, in particular to an anti-wrinkle finishing agent and an anti-wrinkle finishing method for cotton fabrics. Background technique [0002] Cotton fiber is a kind of natural cellulose fiber. Its microstructure is microfibrils formed by the aggregation of dozens of chain-like cellulose macromolecules. The microfibrils continue to aggregate into fibrils with a lateral size of about 10-25nm. Then the fibrils are arranged to form the sun ring layer, and finally the fibers are formed. The microscopic interior of cotton fibers is a porous material. Due to its own characteristics, it has good air permeability, moisture permeability and outstanding comfort, so it is loved by consumers. Due to the influence of various external factors during the wearing process, various creases and deformations are formed, which affects the appearance of the fabric on the one hand, and reduces the durabili...
