Problems solved by technology

Sodium chlorite is also a good bleaching agent for chemical fibers. The whiteness stability of bleached fabrics is better than that of chlorine bleached and oxygen bleached fabrics, but sodium chlorite is more expensive and highly corrosive to metals. Titanium or titanium is required. Alloy and other materi...

Abstract

The invention discloses a method for pre-treating a cotton-polyester blended fabric with a biological enzyme. The method comprises the steps of scouring and bleaching, washing and drying and is characterized in that the scouring and bleaching step comprises the sub-step of adding the cotton-polyester blended fabric to a scouring and bleaching solution to be scoured and bleached, wherein the mass ratio of the cotton-polyester blended fabric to the scouring and bleaching solution is (1:10)-(1:20); the temperature is controlled to be 50-60 DEG C; the treatment time is 30-90 minutes; and the scouring and bleaching solution comprises the following components by weight percent: 2.5-3.5% of compound biological enzyme, 5-10% of hydrogen peroxide, 1-2% of tetra acetyl ethylene diamine, 0.1-0.3% of sodium cocoamphoacetate, 0.1-0.3% of ferrous sulfate and the balance of water. The method has the advantages of desizing and bleaching in one bath, mild treatment conditions, small damage to the fabric and short treatment time.

Description

technical field [0001] The invention relates to a fabric pretreatment method, in particular to a biological enzyme pretreatment method for cotton-polyester blended fabric. Background technique [0002] In the textile dyeing and finishing process, the fabric with yarn as warp must be sizing before weaving to improve the strength, wear resistance and smoothness of warp yarn, thereby reducing warp yarn breakage and ensuring smooth 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 ...
