Problems solved by technology

However, due to the poor hydrophobicity of polyester and other thin chemical fiber fabrics, the hygroscopicity and permeability during printing are insufficient, resulting in the infiltration printing of polyester thin fabrics. Therefore, the penetration printing of polyester thin fabrics has always been a difficult problem in the industry.

Abstract

The invention discloses a processing method for penetration printing of polyester fabric. The processing method comprises the following step: performing grafting pretreatment and water washing on thedesized polyester fabric. The grafting process comprises the following step: carrying out a grafting reaction on the polyester fabric by adopting a mixture of methacrylic acid and methyl methacrylate,wherein alkyl glycoside, citric acid, ammonium persulfate or potassium persulfate are used as auxiliary agents for assisting grafting. The polyester fabric is subjected to grafting pretreatment, so that the hydrophilicity of the fabric is improved, and preconditions are provided for penetration printing; and in addition, during printing, N-octyl pyrrolidone is adopted, so that polyester fibers can be plasticized, fiber pores are enlarged, and high-temperature migration of dye is facilitated. The invention can solve the technical problem that how to enable fabric printing to achieve consistentcolor of front and back sides and high definition.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a processing method for polyester fabric penetration printing. Background technique [0002] Printing refers to the use of dyes or paints to form patterns and characters on the surface of fabrics. The pattern and color of general fabric printing are mainly on the front side, and there are no special requirements on the back side. But as people's requirements for fashion, personality and aesthetic textiles increase, the demand for high-permeability printed fabrics increases, especially double-sided printed fabrics. At present, with the development of electronic technology, some manufacturers use high-precision digital printing twice to realize double-sided printing, but this printing method requires high equipment, long production cycle and high production risk. The traditional screen printing process realizes the high-penetration printing process on some thin natur...
