Abstract

The invention belongs to the technical field of spinning, and particularly relates to a method for preparing water-proof and moisture permeable coated fabrics. The method comprises the following steps of: a, pre-water repellency finishing of the fabrics: performing one-time-padding and one-time-batching water repellency treatment on the fabrics by adopting a fluorine-based water repellency finishing agent; prebaking the fabrics for 1 to 3 minutes at the temperature between 80 and 100 DEG C; and baking for 60 to 90 seconds at the temperature between 140 and 180 DEG C; b, coating finishing, wherein a coating agent comprises the following components in parts by weight: 100 parts of water-based coating agent, 2 to 6 parts of surfactant and 15 to 25 parts of cellulose ethers or derivants thereof diluted with water in the ratio of 1:20; and c, prebaking for 1 to 3 minutes at the temperature between 80 and 100 DEG C, and then baking 60 to 90 seconds at the temperature between 120 and 160 DEG C. According to the invention, a method for adding cellulose ethers or the derivants thereof into the water-based coating agent to serve as a thickening agent is adopted, moisture permeable porous are formed in a membrane by utilizing the cellulose ethers or the derivants thereof and the high moisture permeability of the cellulose ethers or the derivants thereof in the membrane are utilized, so that the moisture permeability of the coated fabrics is improved by dual-moisture permeability; and the method can be applied to all water-based coating agents.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing a waterproof and moisture-permeable coated fabric. Background technique [0002] Coating technology can endow textiles with unique appearance and functions, such as: making fabrics have pearlescent, reflective, double-sided two-color or leather appearance effects; endowing fabrics with functions such as waterproof, oil-proof, acid and alkali resistance, and radiation protection. The original coated fabric was made of natural rubber. At the end of the 18th century and the beginning of the 19th century, there was a patent in the United Kingdom on the manufacture of rainproof cloth from rubber emulsion. The main function of its product is waterproof. In modern times, with the advent of synthetic polymer materials such as polyvinyl chloride, polyurethane and polyacrylate, the fabric coating industry has developed rapidly and has become a powerful i...
