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...

Embodiment 1

[0033] (1) Preparation of compound biological enzyme

[0034] Weigh 15 parts by weight of cutinase, 40 parts by weight of alkaline pectinase, 15 parts by weight of 1,4-B-D-glucose-4-glucoside hydrolase and 30 parts by weight of laccase, stir and mix evenly to obtain The compound biological enzyme.

[0035] (2) Preparation of scouring bleaching solution

[0036] At room temperature, add compound biological enzyme, hydrogen peroxide, tetraacetylethylenediamine, babassu oleamide propylamine oxide and sodium chloride into water, stir and mix evenly to obtain a scouring bleaching solution, the scouring bleaching Liquid, composed of the following components by weight percentage: 3% of the compound biological enzyme, 7.5% hydrogen peroxide, 1.5% tetraacetylethylenediamine, 0.2% babassu oleamide propylamine oxide, 0.2% sodium chloride %, the balance is water.

[0037] (3) Scouring and bleaching in the same bath

[0038] The pure cotton fabric is added into the scouring and bleachi...

Abstract

The invention discloses a bio-enzyme pretreatment method of a pure cotton fabric, which comprises the following steps: (1) adding a pure cotton fabric into a boiling and bleaching solution to carry out boiling and bleaching, wherein the mass ratio of the pure cotton fabric to the boiling and bleaching solution is 1:10-1:20, the temperature is controlled at 50-60 DEG C, the treatment time is 30-90 minutes, and the boiling and bleaching solution is prepared from the following components in percentage by weight: 2-4% of composite bio-enzyme, 5-10% of hydrogen peroxide, 1-2% of tetraacetyl ethylenediamine, 0.1-0.3% of babassu oil amide propyl amine oxide, 0.1-0.3% of sodium chloride and the balance of water; and (2) washing with water, and drying. By performing desizing and bleaching in the same bath, the invention has the advantages of mild treatment conditions, small damage to fabrics, and short treatment time.

Description

technical field [0001] The invention relates to a fabric pretreatment method, in particular to a pure cotton fabric biological enzyme pretreatment method. 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 is higher, and th...
