Problems solved by technology

[0003] The common denim printing paste commonly used now is water-based printing paste, which can be printed on non-coated denim to obtain good color fastness, but if ordinary denim printing paste is used on coated denim Printing, because of the waterproof coating of coated denim, ordinary denim printing glue cannot be bonded to the cloth surface fibers, and the printed glue film of denim clothing will fall off in large areas after washing, stone grinding, etc. Fastness is extremely low

Abstract

The invention discloses a printing rubber paste for coating denim and a screen mesh printing method using the printing rubber paste. The printing rubber paste for coating denim comprises, by weight, a component A, a component B and a component C, the component A comprises 15-20 parts of an acrylate adhesive, 5-10 parts of a polyurethane adhesive, 0.5-0.8 parts of an emulsifier, 0.5-2 parts of a thickener, 0.3-0.8 parts of sodium methylene bis-naphthalene sulfonate and 0.5-1 part of a softener, the component B is a crosslinking agent with the weight parts of 0.5-3, and the component C is an assistant with the weight parts of 2-4, wherein the component C can destroy the water proof coating of the coating denim, the component A can be combined with the cloth cover fiber of the denim through the self-crosslinking of the component A, and the component B has an effect on the promotion of the bonding crosslinking of the component A to form a stable reticular structure. The printing rubber paste of the invention can be directly used to print the coating denim, and the good color fastness can be still obtained after washing and stone processing.

Description

technical field [0001] The invention relates to the printing and dyeing technology of the textile industry, in particular to the printing and dyeing of denim, in particular to a printing glue for coated denim and a screen printing method for coated denim using the printing glue. Background technique [0002] Coated denim is a polymer compound that can form a film evenly coated on the surface of denim, so that the fabric can change the appearance, style or endow various functions. In order to meet the hydrophobicity required by the coating, polyacrylate PA coating is often used. Layer agent and / or polyurethane PU coating agent. [0003] The common denim printing paste commonly used now is water-based printing paste, which can be printed on non-coated denim to obtain good color fastness, but if ordinary denim printing paste is used on coated denim Printing, because of the waterproof coating of coated denim, ordinary denim printing glue cannot be bonded to the cloth surface fi...
