Problems solved by technology

With the continuous improvement of consumers' awareness of product quality and high-end demand for high-end fabrics, the requirements for cotton fabrics are getting higher and higher. The market requires pure cotton mercerized fabrics to feel more fluffy, soft, and brighter, and the overall improvement of pure cotton fabrics It has a silky luster and a more drape feeling. The previous mercerized products can no longer meet the market demand.

Embodiment 1

[0014] Example 1: Using 80 / 2 raw yarn as raw material, the fabric is CM80 / 2*CM80 / 2*160*72*57, the specific steps are:

[0015] 1. Yarn mercerizing: yarn mercerizing is carried out in a cheese dyeing machine with a cheese yarn mercerizing method. The concentration of sodium hydroxide aqueous solution is 200g / l, the temperature is 20℃, and the mercerizing time is 50s. Yarn density value is 0.34kg / cm 3 .

[0016] 2. Yarn singeing: When the yarn is singed, the moving speed of the yarn is 1000m / min, and the yarn tension is 1.6CN.

[0017] 3. Yarn dyeing: The pre-treatment process in yarn dyeing is to add hydrogen peroxide with a mass ratio of 29% to the dye liquor to make the hydrogen peroxide content in the dye liquor 8g / l, and then make the dye liquor change from room temperature to 2℃ / l. Min heating rate rises to 110℃, keep for 40min; then drain the dye liquor, refill the yarn into water, add FN dye and L-450 retarder to the water, and the mass ratio of FN dye in the dye liquor is 2% ...

Embodiment 2

[0025] Example 2: Using 120 / 2 raw yarn as raw material, the fabric is CPT120 / 2*120 / 2*210*105*57 twill pattern.

[0026] The specific steps are:

[0027] 1. Yarn mercerizing: yarn mercerizing is carried out in a yarn dyeing machine using cheese yarn mercerizing, the concentration of sodium hydroxide solution is 280g / l, the temperature is 25℃, the mercerizing time is 50s, the original yarn density value before the yarn mercerizing 0.34kg / cm 3 .

[0028] 2. Yarn singeing: When the yarn is singing, the moving speed of the yarn is 1050m / min, and the yarn tension is 1.6CN.

[0029] 3. Yarn dyeing: The pre-treatment process in yarn dyeing is to add hydrogen peroxide with a mass ratio of 29% to the dye liquor to make the hydrogen peroxide content in the dye liquor 8g / l, and then make the dye liquor change from room temperature to 3℃ / l. The min heating rate is increased to 110℃ and kept for 40 minutes; then drain the dye liquor, refill the yarn into water, add FN dye and L-450 retarder to the...

Abstract

The invention provides a method for producing advanced triple-wire double-calcination pure cotton fabrics, comprising the working procedures of yarn dyeing, weaving, fabrics singeing, desizing, alkali mercerization, tenter setting and preshrinking. The method is characterized in that before being dyed, grey yarns are mercerized and singed, and a liquid ammonia working procedure is added between alkali mercerization and tenter setting, thereby forming the whole processing steps sequentially including yarn mercerization, yarn singeing, yarn dyeing, weaving, fabrics singeing, desizing, alkali mercerization, liquid ammonia, tentering and preshrinking. Compared with the traditional mercerized pure cotton fabrics, the triple-mercerization pure cotton fabrics obtained by the method have the advantages of higher lustre and high tinctorial yieldof yarns, fresher color of fabrics, good moisture absorption and ventilation, soft handle and high resilience, and the triple-wire double-calcination pure cotton fabrics are softer after being washed and maintain other excellent performances thereof.

Description

Technical field [0001] The invention relates to a finishing production process of high-grade three-mercerized double-burned cotton fabric, which belongs to the technical field of textiles. technical background [0002] At present, the mercerizing finishing of pure cotton fabrics in the market is limited to single mercerizing and double mercerizing. Multi mercerizing can make up for the natural defects of cotton fiber's dull luster. After mercerizing yarns, cotton mercerizing, and liquid ammonia, the fabrics can be brightened. Features, while having the comfort of pure cotton products. With consumers' increasing awareness of product quality and high-end demand for high-end fabrics, the requirements for cotton fabrics are getting higher and higher. The market requires pure cotton and mercerized fabrics to feel more fluffy, softer and brighter. The overall improvement of pure cotton fabrics The high-grade products have silky luster and more drape. The first mercerized products can ...
