Problems solved by technology

This type of adhesive has the advantages of relatively good fastness and convenient use, but it needs to be baked at high temperature (150°C), which consumes a lot of energy, especially in the process of use, it will release formaldehyde and printing which are harmful to the human body and the environment. Or dyed fabrics feel hard and other defects

Abstract

The invention discloses a preparation method and application of a nano-scale formaldehyde-free paint printing and dyeing adhesive. The adhesive is composed of N-glycidyl acrylamide crosslinking monomer, butyl acrylate, isooctyl acrylate, Ethyl acrylate, methyl methacrylate, styrene, vinyl acetate, acrylic acid, methacrylic acid, reactive surfactants, unsaturated strong hydrophilic monomers, vinyl-containing silicone monomers, etc. The particle size of the binder of the invention can reach nanometer level and does not contain formaldehyde. It can be used for both pigment printing and pigment dyeing, and can also be used in other fields such as new adhesives in the construction field. When the adhesive is used for pigment printing, it does not block the screen, the pattern is fine and clear, the fabric feels soft and has excellent fastness, and when it is used for pigment dyeing, it does not stick to the roller and runs smoothly.

Description

1. Field of invention [0001] The invention relates to a textile printing and dyeing adhesive and its preparation method and application, more particularly to a nano-scale formaldehyde-free paint printing and dyeing adhesive and its preparation method and application. 2. Background technology [0002] With the continuous improvement of adhesives for pigment printing and the advent of synthetic thickeners, the advantages of fabric pigment printing are becoming more and more prominent, such as: no need for steaming and wet treatment, not affected by fiber properties, short process flow, The production cycle is fast, the authenticity rate is high, and the investment in equipment is small. It can save a lot of energy, water resources and washing aids, greatly reduce waste water pollution, and is beneficial to environmental protection. Therefore, its development is very rapid, and pigment printing in developed countries has accounted for about 70% of printing. The amount of pigm...
