How is Cotton Fabric Made?

Cotton fabric, also called cotton fabric, is a fabric woven with cotton yarn as raw material. Cotton fabric has become one of the most commonly used fabrics with excellent wearability, and is widely used in apparel fabrics, decorative fabrics and industrial fabrics. Cotton is the most popular clothing and home textile. Versatility, softness, breathability, moisture absorption, year-round comfort, excellent performance and durability are just a few of the many qualities of cotton that are popular.

The production of cotton fabrics includes

Cotton fabrics are inexpensive and have a wide range of applications. They are better underwear, baby clothes, and summer fabrics, as well as popular spring and autumn outerwear fabrics. The main characteristics of cotton fabrics are:

(1) Has good moisture absorption and breathability, comfortable to wear;

(2) Soft to the touch, soft luster and rustic;

(3) Good warmth and excellent taking performance;

(4) Good dyeing, bright color, complete color spectrum, but color fastness is not good enough;

(5) Alkali-resistant and acid-resistant, concentrated alkali treatment can make the fiber cross section in the fabric round, thereby improving the gloss of the fabric, that is, the mercerizing effect.

(6) Light resistance is good, but long-term exposure will cause discoloration and strength decrease;

(7) Poor elasticity, easy to produce wrinkles and difficult to recover creases;

(8) Pure cotton fabrics are prone to mildew and deterioration, but resistant to insects.

Cotton fabrics are also called cotton fabrics, which refer to cotton fabrics.

Cotton fabrics are highly absorbent, wear-resistant, washable, soft and comfortable. They have good warmth in winter and breathable and cool in summer. Cotton fabrics have become one of the most commonly used children's clothing materials because of their excellent wearability. However, its elasticity is poor, the shrinkage rate is large, and it is easy to wrinkle. Cotton fabrics are generally bright in color and are mostly used in children's summer wear, casual wear, underwear, and sports wear.

Poor acid resistance, poor elasticity, large shrinkage rate, easy to wrinkle, easy to mold Volkswagen coat.

First, plain cloth

thick

1. Cotton fabric has strong alkali resistance, acid resistance and high temperature resistance. Various detergents can be used, but try not to use washing powder, it is better to use transparent soap or soap powder, soap paste. Dilute the wash with warm water first, and let the clothes soak after cooling down. Not suitable for chlorine bleaching;

2. Colored laundry can be soaked in water for several minutes before washing, but it should not be too long, so as not to damage the color.

3. White laundry can be washed at high temperature with a strong alkaline detergent to play the role of bleaching;

4. Underwear cannot be soaked in hot water, so as to prevent the protein in sweat stains from solidifying and sticking to the clothing, which will cause yellow spots.

5, it is best not to machine wash knitwear

6. Different colored cotton fabrics should be washed separately;

7. Do not scrub with a washing board or a hair brush.

8. When rinsing, you can master the method of "a small number of times", that is, it is not necessary to use a lot of water for each rinse; After each rinse, it should be wrung out and then rinsed a second time to improve the washing efficiency.

9. It should be dry in the shade, and clothes should be in a ventilated and cool place, avoiding exposure to strong sunlight, so as to avoid discoloration of colored fabrics, and drying inside and out.

10. Pay attention to ventilation and avoid humidity to avoid mold.

11. Underwear cannot be soaked in hot water to avoid yellow sweat spots.

12, it is best not to machine wash knitted products, do not use force to wring, knitted products can not be pulled with force.

The process of dyeing and finishing cotton knitted fabrics includes processes such as scouring, dyeing, printing, and finishing. It plays an important role in improving the appearance of knitted fabrics, improving the performance, improving product quality, and increasing the variety of colors.

1. The main processes of bleaching and bleaching cotton knitted fabrics include scouring, bleaching, alkali shrinking, waxing, etc. Among them, the processing principles and agents for scouring and bleaching are the same as those for cotton, and will not be repeated. However, cotton knitted fabrics are connected by loops. The gap between the yarns is large, which is easy to deform and cannot withstand large tension. Therefore, loose processing equipment must be used during processing. The following briefly introduces the processes of alkali shrinking and waxing.

1) Alkali shrinking: Cotton knit fabric alkali shrinking is a process in which cotton knit fabrics are treated with concentrated alkali in a relaxed state. Cotton fibers swell in concentrated caustic soda, fabric shrinks, fabric density and elasticity increase, and processing of fabrics such as jersey with loose tissues, alkali shrinking includes three steps, namely padding lye, stacking shrinkage and washing to remove alkali.

2) Waxing: After knitting and bleaching of cotton knitted fabrics, the friction between the fibers increases after the oily wax substance of the cotton fibers is removed. During sewing, the fibers are not easy to slip, and the needles can easily break the fibers, which causes needle holes in the fabric, which affects the fastness of wearing. In order to solve this problem, in addition to strictly controlling the process conditions, a softening process is performed at the same time, that is, waxing is performed, and the dehydrated fabric is dipped into a paraffin wax emulsion and then deliquored and dried.

2. Dyeing and printing of cotton knitted fabrics are basically the same as those of cotton fabrics and will not be repeated here. Rope when dyeing

1. Bamboo fiber blended fabric

Bamboo fiber is a new type of regenerated cellulose fiber, which has the characteristics of good strength, high abrasion resistance, good moisture absorption and permeability, good air permeability, and good antibacterial properties.

Dyeing and finishing method of bamboo fiber / fine denier polyester / cotton blended knitting yarn, the process is as follows: grey fabric preparation alkali reduction bleaching dyeing soft finishing post treatment finished product. The purpose of alkali reduction is to improve the wearability of the fabric. NaOH 20-35g / L, treated at 125 for 35 45min; dyeing with disperse and reactive dyes; The post-treatment adopts calendering setting, 95-100 ° C, overfeeding 13-15%, so that the bamboo fiber blended knitted fabric has a unique smooth, soft, waxy and cool style.

Mercerized wool light fabric

For 25rex single warp and single weft mercerized wool lightweight fabrics, the best effect is to use IA0 biological enzyme desizing, and the pulp is cleaned, which is conducive to dyeing and finishing. Reasonable selection of dyes and auxiliaries is an important measure to overcome the fast absorption and easy dyeing of mercerized wool during dyeing. In the oxygen bleaching process, a wool protection agent can be selected to alleviate the damage to the wool. The choice of CibafluldC can give the wool fabric a full and elastic feel. ^[2]
