Problems solved by technology

However, since the pigment printing process forms a thin film on the surface of the fiber, its hand feeling is not as natural and soft as dye printing, especially in large-area patterns.
[0004] Since 2000, my country's home textile industry has developed rapidly at an annual growth rate of more than 20%. In the home textile industry, the patterns on the bed sheets and quilts made of pure cotton and polyester cotton are usually printed with reactive dyes. The biggest disadvantage of this process is that it consumes a lot of energy. , great environmental pollution and high cost
This patent discloses the use of trimethyl isocyanate as a functional monomer, indicating that it is actually a polyurethane-modified acrylate emulsion. Due to the use of polyurethane, this adhesive has high cost and is prone to yellowing and other shortcomings

Abstract

The invention relates to an active coating imitating printing adhesive and a preparation method thereof. Dodecyl alcohol polyoxylethylene ether, sodium dodecyl sulfate, N-hydroxy methacrylamide, acrylic acid-2-propyl heptyl ester, 2-ethylhexyl acrylate, silicone oil, acyclic acid, methacrylamide, methyl acrylate, acrylonitrile, potassium persulfate and deionized water are manufactured into a waterborne emulsion by adopting an emulsion polymerization method. The hand feel of the printing of the product is comparable with the hand feel of the printing of a reactive dye. The active coating imitating printing adhesive has the advantages of bright color, high dry and wet rubbing fastness, high soaping fastness and the like.

Description

technical field [0001] The invention relates to a textile pigment printing adhesive and a preparation method thereof, which is an acrylic pigment printing adhesive imitating the printing effect of reactive dyes and a preparation method thereof. Background technique [0002] Dye printing is a chemical reaction in which dyes and fibers are chemically bonded. Different fibers choose different dyes. For pure cotton and polyester cotton fabrics, reactive dye printing is the most common and commonly used method. It has the advantages of soft hand feeling and good color fastness, especially suitable for printing of soft close-fitting fabrics and large-area printing. However, reactive dye printing requires corresponding baking and post-washing treatment procedures, which consumes water, energy, and causes huge environmental pollution. [0003] Pigment printing is a printing process in which pigments are adhered to the surface of fibers by means of adhesives to obtain desired patte...
