A Dissolution Printing Process for Elastic Fiber Fabric

Abstract

The invention relates to a dissolving printing technique of an elastic fiber fabric, belonging to the technical field of preparing special woven fabric. The dissolving printing technique comprises the steps of winding, loosening, pre-setting, pretreatment, printing, aging, washing, dehydration, drying and setting sequentially, the printing consists of dyeing and dissolving treatment, the solution for dissolving treatment is mixed with a dyeing auxiliary sodium alginate paste for use, after the solution and the sodium alginate paste are evenly mixed, the elastic blended fabric is dissolved into designed flower types and patterns through a mould, flat scream printing or manual smearing, and the solution comprises the following compositions in percentage by weight: 88% of N,N-dimethylformamide, 2% of dibutyltin dilaurate, and 10% of mineral oil. By adopting the technical scheme, the elastic fiber fabric has the advantages of excellent in breathability, low processing cost and good three-dimensional effect, and is convenient and fast to operate.

Description

technical field [0001] The invention relates to a process for dissolving printing of elastic fiber fabrics, which belongs to the technical field of processing special woven fabrics. Background technique [0002] With the development of fabric processing technology, clothing fabrics must not only meet the advantages of high softness, cool air permeability, and good sweat absorption, but also meet a certain degree of decoration and aesthetics. Various methods such as printing or jacquard can be formed. The pattern and color of the fabric, but lack of three-dimensional effect after molding; although hot embossing and coating rigidity can give the fabric a certain three-dimensional effect, but the heat treatment is easy to cause color difference, and the three-dimensional effect is not permanent. The middle pattern will gradually disappear, while the creases and wrinkles left by heat pressing will affect the visual effect, and the fabric after heat pressing treatment will feel s...

[0002] With the development of fabric processing technology, clothing fabrics must not only meet the advantages of high softness, cool air permeability, and good sweat absorption, but also meet a certain degree of decoration and aesthetics. Various methods such as printing or jacquard can be formed. The pattern and color of the fabric, but lack of three-dimensional effect after molding; although hot embossing and coating rigidity can give the fabric a certain three-dimensional effect, but the heat treatment is easy to cause color difference, and the three-dimensional effect is not permanent. The middle pattern will gradually disappear, while the creases and wrinkles left by heat pressing will affect the visual effect, and the fabric after heat pressing treatment will feel stiff, and the air permeability and wearing effect will be poor; yarns with different elasticity are used to interweave or weave to Three-dimensional effect can be obtained, but the process is extremely complicated, the pattern is easy to run lines, wrong colors, and the practicability is not good
