Problems solved by technology

However, the existing nylon imitation cotton fabrics have the following disadvantages like ordinary cotton fabrics: the washing shrinkage of the fabric is large, the dimensional stability is poor, and there may even be ironing shrinkage in the garment factory, resulting in different styles and sizes; The batch quality varies and the width is unstable; the production process of the fabric consumes a lot of energy, the dyeing is not transparent, and the fabric surface is easy to wrinkle, which affects the fabric feel

preparation example Construction

[0019] The preparation process of a low-shrinkage nylon imitation cotton fabric of the present invention is carried out according to the following process: gray cloth weaving→cold stacking treatment→desizing→dyeing→dehydration opening→setting.

[0020] The gray cloth used for the preparation process of the nylon imitation cotton fabric of the present invention: the warp and weft are all selected 90D nylon matting ATY filaments, the total warp is: 7115, the reed width of the upper machine: 182.5cm, the reed number: 19.5#, and the warp density is 43.3 Roots / cm, the weft density is 31.5 roots / cm; the gray cloth is woven after warping, and the width of the gray cloth is about 164±1cm. When designing the machine process of gray fabrics, the total number of warp yarns is not increased, and the width of the door is widened, so that the warp and weft yarns have sufficient shrinkage space, the warp density is reduced, and the gap between the warp yarns is increased; at the same time, th...

Embodiment 1

[0022] The cold-stack treatment is to dip the gray cloth in the cold-stack padding liquid in the padding tank for padding treatment, then roll and seal, and stack the sealed cloth rolls on the cold-stack stand for 24 hours, and at the same time Keep the cloth roll rotating slowly at a speed of 16 m / min to ensure that the padding liquid can fully and effectively penetrate into the interior of the fiber. Solubilization, emulsification, saponification, decomposition, oxidation, swelling; the padding solution of the cold pad batch treatment contains refining agent, H 2 0 2 and a mixed aqueous solution of NaOH; wherein the refining agent is refining agent TK-1, and the padding liquid treated by the cold stack is made of H 2 0 2 , NaOH, refining agent in a weight ratio of 9:20:2; the deionized water is refining agent, H 2 0 2 and 30 times the sum of the weights of NaOH.

[0023] The desizing process of the present invention adopts loose-type open-width desizing, which is carrie...

Embodiment 2

[0027] The cloth rolls after the cold-batch processing, rolling and sealing are stacked on the cold-stack rack for 20 hours, while keeping the cloth rolls slowly rotating at a speed of 16 m / min; 2 0 2 and a mixed aqueous solution of NaOH; wherein the refining agent is refining agent TK-1, and the padding liquid treated by the cold stack is made of H 2 0 2 , NaOH, refining agent in a weight ratio of 11:20:2; the deionized water is refining agent, H 2 0 2 And 33 times of NaOH weight summation, other conditions are all identical with embodiment 1.

[0028] The refining tank working fluid is an aqueous solution prepared by mixing NaOH, desizing and refining agent, chelating dispersant, and penetrating agent in a weight ratio of 20:6:2:3, and adding deionized water 34 times the sum of the weight of the four; , The desizing and refining agent is desizing and refining agent JD-26; the chelating dispersant is chelating dispersant SR; the penetrating agent is penetrating agent OT-3...

Abstract

The invention discloses a preparation process of low-shrinkage nylon cotton-like fabrics. The preparation process is characterized by comprising the following steps of gray fabric weaving, cold pad-batch process, desizing, dyeing, dehydrating and scutching, and shaping, wherein the cold dome treatment comprises the steps of impregnating gray fabrics in a cold dome padding liquid in a padding groove of a padder for padding, then rolling and sealing the gray fabrics, yarding sealed yardage rolls on a cold pad-batch frame for 20-24 hours, and slowly rotating the yardage rolls at a speed of 16-18m / min at the same time; the padding liquid in the padding groove is aqueous solution which is prepared by mixing H2O2, NaOH and a refining agent in a weight ratio of (9-11):20:2 and then adding deionized water the weight of which is 30-33 times the total weight of H2O2, NaOH and the refining agent into the mixture; and the refining agent is a refining agent TK-1. By virtue of the process, the surfaces of the fabrics are more uniform in coloring and are smoother, and warps and wefts are fully shrunk, so that the quality of the finished fabrics is improved, the warp and weft shrinkage of the fabrics can reach a high standard, and the size stability of the fabrics is good.

Description

technical field [0001] The invention relates to a fabric and its weaving and dyeing process, in particular to a nylon-like cotton-like shrink-resistant fabric and its weaving and dyeing process. Background technique [0002] With the development of society and the continuous improvement of living standards, people have higher and higher requirements for the comfort and functionality of clothing fabrics. Nylon imitation cotton fabrics not only have the appearance, feel and hygroscopic properties of cotton fabrics, but also have better properties than cotton fabrics. It is strong, easy to wash and dry, high-strength and wear-resistant, and has good cold resistance. It has always been the preferred fabric for leisure and sports, and is very popular among consumers. However, the existing nylon imitation cotton fabrics have the following disadvantages like ordinary cotton fabrics: the washing shrinkage of the fabric is large, the dimensional stability is poor, and there may even ...
