Abstract

The invention discloses a function prepolymer and a preparation method and application thereof. The function prepolymer is a butyl acrylate polymer and prepared from a monomer, modified matter and an emulsifying agent through emulsion polymerization. A synthetic thickener, liquid disperse dye and the function prepolymer are mixed with water and evenly stirred to obtain printing paste; printing and drying of a polyester fabric are achieved through the obtained printing paste on a rotary screen printing machine or a mobile screen printing machine, then high-temperature processing is carried out on a tentering heat setting machine, and a printed polyester fabric is obtained. According to the technical scheme, the printing process is short, the hand feeling of the fabric is soft, postprocessing is not needed, a large amount of water and energy are saved, almost no wastewater is drained, processing equipment is conventional, and the printing processing technology is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a functional prepolymer and its preparation method and application, which are used in a short-flow, energy-saving and emission-reducing printing process for direct printing of polyester fabrics. Background technique [0002] The emulsion polymerization of acrylate is the biggest application of acrylate. According to the different physical and chemical requirements for polymer formation, acrylate can be copolymerized with other vinyl monomers. For example, monomers that impart hardness to polymers include vinyl acetate, styrene, methyl methacrylate, acrylonitrile, etc.; monomers that impart surface adhesion to polymers include acrylic acid, methacrylic acid, methylene succinic acid, etc. body; these monomers give the polymer polarity, which increases adhesion. Resins made from specific acrylates such as butyl acrylate, ethyl acrylate, and 2-ethylhe...
