Embodiment 1

[0023] 1) Preparation of desizing solution: 2 parts by weight of sodium citrate, 0.85 parts by weight of hydrogen peroxide, 0.85 parts by weight of N-methylpyrrolidone, 1 part by weight of isomeric fatty alcohol polyoxyethylene ether phosphate, 1.3 parts by weight of barium petroleum sulfonate , 2 parts by weight of sodium hydroxide, and 21 parts by weight of amylase are dropped into 50 parts by weight of deionized water successively, and stirred evenly; Oxyethylene ether, 0.65 parts by weight of octadecyl dimethyl ammonium chloride, continue to stir until fully mixed, and obtain a desizing solution;

[0024] 2) Fabric pretreatment: Soak the fabric in warm water at 45°C. When soaking, the warm water needs to cover the fabric. Add acetic acid during the soaking process to adjust the pH value of the warm water to 5.5. After the adjustment is completed, stir the fabric for 10 minutes. Take it out after completion;

Abstract

The invention discloses a desizing treatment method for cotton-polyester blended fabrics, each part by weight is 1g, comprising the following steps: preparation of desizing liquid, pretreatment of fabrics, dehydration of fabrics, desizing treatment of fabrics, steaming treatment, Washing treatment and drying treatment; the desizing solution of the present invention is used to desizing the cotton-polyester blended fabric, the desizing rate is high, and the obtained fabric has high gross effect and mechanical properties, which is beneficial to the subsequent printing and dyeing process. The quality of subsequent printing and dyeing is guaranteed; and the hand feeling of the fabric is improved due to the effective removal of the size.

Description

technical field [0001] The invention relates to a desizing treatment method for cotton-polyester blended fabrics. Background technique [0002] In the textile dyeing and finishing process, the fabric with yarn as the warp must be sizing before weaving to improve the warp. [0003] The strength, abrasion resistance and smoothness of the yarn can be improved, thereby reducing warp yarn breakage and ensuring the smooth progress of weaving. The sizing materials used for warp yarn sizing include natural sizing materials such as starch and wild starch, chemical sizing materials such as polyvinyl alcohol (PVA), polyacrylic acid (PAA), and cellulose preparations such as carboxymethyl cellulose (CMC). Other ingredients such as preservatives, softeners, hygroscopic agents, wear-reducing agents, etc. are also added to the sizing solution. The warp sizing rate is related to fiber quality, yarn count, density, etc. For fabrics with fine yarn count and high density, the warp sizing rate...
