Problems solved by technology

Cotton and nylon elastic woven fabrics are popular because of their elasticity, bright colors, luster and softness; however, in the finishing process of conventional cotton and nylon fabrics, there are fabric wrinkles, serious curling, narrow width, and tentering. Poor effect and low elasticity, the tear strength of cotton nylon elastic woven fabrics is low, the finishing process is difficult to control, the rate of first-class fabrics is low, and it cannot meet the quality requirements of high-grade cotton nylon elastic woven fabrics

Embodiment 1

[0008] Embodiment 1: Using cpt40*PA70D+LY20D*130*80*57, the specific steps are:

[0009] 1. Fabric singeing: the singeing speed is 100m / min, the burner position is 1#, and the flame intensity is 6m / bar. Add desizing enzyme at a ratio of 4g / l to the singeing machine fire extinguishing tank to process singeing;

[0010] 2. Cold stacking: 6 hours at room temperature;

[0011] 3. Desizing: add desizing enzyme, penetrating agent and refining agent in the ratio of 4g, 2g, 2g per liter in the trough of the desizing machine, and process desizing at a washing temperature of 90°C;

[0012] 4. Mercerizing: the alkali concentration is 22Be°, carried out on a cloth clip mercerizing machine, the speed is 50m / min, the temperature of the washing tank is 85°C, and the pH value of the falling cloth is 5;

[0013] 5. Liquid ammonia: the vehicle speed is 20m / min, the washing temperature is 60°C, and the pH value of the fabric is 7;

[0014] 6. Pre-stentering: the vehicle speed is 60m / min, and t...

Embodiment 2

[0018] Embodiment 2: The specific steps of using cpt60*PA40D+LY30D*152*96*57 are:

[0019] 1. Fabric singeing: the singeing speed is 110m / min, the burner position is 1#, and the flame intensity is 7m / bar. Add desizing enzyme at a ratio of 6g / l to the singeing machine fire extinguishing tank to process singeing;

[0020] 2. Cold stacking: cold stacking at room temperature for 8 hours;

[0021] 3. Desizing: Add desizing enzyme, penetrating agent and refining agent in the ratio of 6g, 4g, 4g per liter to the trough of the desizing machine, and process desizing at a washing temperature of 92°C;

[0022] 4. Mercerizing: the alkali concentration is 24Be°, carried out on a straight roller mercerizing machine, the speed is 65m / min, the temperature of the washing tank is 85°C, and the pH value of the falling cloth is 6.5;

[0023] 5. Liquid ammonia: the vehicle speed is 35m / min, the washing temperature is 68°C, and the pH value of the fabric is 6.4;

[0024] 6. Pre-stentering: the ve...

Embodiment 3

[0028] Embodiment Three: The specific steps of using cpt50*PA70D+LY20D*152*96*57 are:

[0029] 1. Fabric singeing: the singeing speed is 120m / min, the burner position is 1#, and the flame intensity is 6m / bar. Add desizing enzyme at a ratio of 4g / l to the singeing machine fire extinguishing tank, and process singeing:

[0030] 2. Cold stacking: cold stacking at room temperature for 10 hours;

[0031] 3. Desizing: Add desizing enzyme, penetrating agent and refining agent in the ratio of 8g, 6g, 6g per liter to the trough of the desizing machine, and process desizing at a washing temperature of 95°C;

[0032] 4. Mercerizing: the alkali concentration is 25Be°, carried out on a cloth clip mercerizing machine, the speed is 70m / min, the temperature of the washing tank is 85°C, and the pH value of the falling cloth is 7.5;

[0033] 5. Liquid ammonia: the vehicle speed is 50m / min, the washing temperature is 70°C, and the pH value of the fabric is 5;

Abstract

The invention provides a method for finishing cotton-nylon elastic woven fabrics, and the process flow comprises singeing, desizing, mercerizing, dry setting and preshrinking, which is characterized in that a step of cold batching yarding is added between the steps of singeing and desizing, and the steps of liquefying ammonia and pre-tendering are added between the steps of mercerizing and dry setting, therefore the whole process flow is as follows: singeing, cold batching yarding, desizing, mercerizing, liquefying ammonia, pre-tendering, dry forming and preshrinking. The invention has scientific and easily-operated process, compared with conventional cotton-nylon elastic woven fabrics, the cotton-nylon elastic woven fabrics obtained by the invention has better gloss, greatly improved fabric color brightness, no fold and turned edge on surface fabric, uniform fabric width, good tendering and setting effects, favorable elasticity up to 20-30% and the first-rate product rate above 99%, can further perfect the stability of product quality and satisfies high quality requirement on top grade fabrics.

Description

technical field [0001] The invention relates to a method for finishing cotton and nylon elastic woven fabrics, belonging to the technical field of textiles. technical background [0002] The pursuit of comfort and freedom, fashion personality has become a worldwide trend. Especially in terms of textile and clothing, people pay more and more attention to the diversity and comfort of clothing materials, and hope that the clothing materials can have higher elasticity during wearing, so that people can be more comfortable in the process of moving. Cotton and nylon elastic woven fabrics are popular because of their elasticity, bright colors, luster and softness; however, in the finishing process of conventional cotton and nylon fabrics, there are fabric wrinkles, serious curling, narrow width, and tentering. The disadvantages of poor effect and low elasticity are that cotton nylon elastic woven fabric has low tear strength, the finishing process is difficult to control, and the ...
