[0016] 3) The bleach solution is 0.3 parts of potassium borate; 1 part of diethylenetriaminepentamethylene phosphonic acid; 1.5 parts of acrylic acid maleic acid copolymer; 0.8 parts of 1,5-anhydrous glucitol; 1.5 parts of caprolactam activator; 0.6 parts of acetylethylenediamine; 7 parts of sodium hydroxide; 5 parts of hydrogen peroxide; 1000 parts of water, padding and bleaching solution, the temperature is 30 ° C, steamed for 60 seconds, rinsed and washed;

[0017] 4) The fabric is mercerized in sodium hydroxide solution, and the concentration of sodium hydroxide solution is 220g / L;

[0018] 5) The fabric afte...

Embodiment 2

[0020] 1) J T / C 60 / 40 is singed on the gas singeing machine, the cloth body temperature is 175°C, and the cloth is dropped after singeing, and the cloth body temperature is 45°C;

[0021] 2) For desizing with amylase, add 2000L 5g of amylase, 4g of NaCl, 3.5g of penetrant per liter of water, keep the temperature of the chemical tank at 50°C, and stack for 12 hours;

[0022] 3) The bleach solution is 0.3 parts of potassium borate; 1 part of diethylenetriaminepentamethylene phosphonic acid; 1.8 parts of acrylic acid maleic acid copolymer; 0.8 parts of 1,5-anhydrous glucitol; 2 parts of caprolactam activator; 0.7 parts of acetylethylenediamine; 6 parts of sodium hydroxide; 6 parts of hydrogen peroxide; 1000 parts of water, padding and bleaching solution, the temperature is 30 ° C, steamed for 60 seconds, rinsed and washed;

[0023] 4) The fabric is mercerized in sodium hydroxide solution, and the concentration of sodium hydroxide solution is 230g / L;

[0024] 5) The mercerized fa...

Embodiment 3

[0026] 1) Gross effect test

[0027] Dye preparation of the test solution: Weigh 1g of reactive red BF-3B dye and fully dissolve it in hot water at 95°C and dilute it to 100cc as a 1% solution.

[0028] Cut the pre-treated test cloth sample into strips of 20cm in the warp direction and 2cm in the weft direction, draw a parallel line with a pencil along the weft direction at a distance of 1cm from one end, and fix the other end of the sample on a horizontal frame for use. It hangs vertically, and the lower end is immersed in the container containing the dye solution, so that the liquid level is exactly aligned with the pencil line. The dye solution rises higher along the warp direction within 10 minutes of measurement, indicating capillary effect.

[0029] 2) Whiteness test

[0030] Measure the whiteness of the pre-treated test cloth samples with computer spectrophotometer CFS57CA, measure the data at three different places of each fabric, and then take the average value, the...

Abstract

The invention relates to a pretreatment process for combed polyester cotton bleached cloth. The pretreatment process comprises the procedures of singeing, desizing, bleaching, mercerizing and heat-shaping, wherein during desizing, the enzyme-desizing cold-dwelling process that desizing anzyme and a penetrant are added into the desizing procedure is adopted; in the bleaching procedure, the following materials are adopted: 0.2-0.4 part of potassium borate serves as the bleaching liquor, 0.8-1.2 part(s) of diethylenetriaminepenta acid (DTPMP), 0.8-2 part(s) of acrylic acid maleic acid copolymer, 0.5-1 part of 1, 5-anhydrous glucitol, 1-2 part(s) of caprolactam activator, 0.4-0.7 part of tetraacetylethylenediamine (TAED), 3-8 parts of sodium hydroxide, 3-7 parts of hydrogen peroxide and 900-1000 parts of water. When the pretreatment process is used for processing fabrics, prominent damage to the fabrics is small; as enzyme desizing is adopted, the desizing ration is improved; the bleaching liquor adopted in the bleaching procedure can effectively improve the whitenness of the fabrics; meanwhile, the pretreatment cost is lowered.

Description

technical field [0001] The invention relates to a fabric processing method, in particular to a pretreatment process of combed polyester-cotton bleached cloth, belonging to the technical field of dyeing and finishing. Background technique [0002] Polyester-cotton blended fabric is made of polyester fiber and cotton fiber in a certain proportion. It not only has the advantages of good wrinkle resistance, crispness, elegance, easy drying after washing, no mildew and no moth, etc., but also soft cotton fabric. , air permeability, good moisture absorption, not easy to pilling and other properties, comfortable to wear, economical and affordable, can meet the needs of different consumption levels. The physical and chemical properties of polyester fiber and cotton fiber are different. During dyeing and finishing, both should be considered. When the fiber blending ratio is different, there should be corresponding processes. At present, polyester-cotton fabrics will appear thin, dul...
