Cotton thread washing method
Cotton thread washing method
1. Cotton yarn fabrics can be washed by hand or machine with various detergents. However, due to the poor elasticity of cotton yarn, it should not be scrubbed vigorously when washing, in order to avoid clothes changing and affecting size.
2. Cotton fibre white clothes can be washed at high temperature with alkaline detergent, which plays a bleaching role. Close underwear can not be soaked in hot water to avoid yellow sweat spots. Other colored shirts should be washed in cold water, not with detergent or detergent containing bleaching ingredients, so as to avoid discoloration, not to pour detergent directly on cotton fabric, in order to avoid partial discoloration.
3. Light-colored and white cotton yarn fabrics can be soaked for 1-2 hours before washing and decontamination effect is better. Dark color should not be soaked for too long to avoid fading. It should be washed in time. A spoonful of salt can be added to the water to make the clothes not fade easily.
4. The dark-colored clothes of cotton fibre yarn fabrics should be washed separately from other clothes in order to avoid dyeing.
5. When washing and draining cotton fibre and yarn clothes, they should be folded up, squeezed out water in large quantities or wrapped up in towels to squeeze water, and must not be twisted forcefully, so as to avoid clothes going out of shape. Also do not drip, so that the clothes will be excessively out of shape after drying.
6. Cotton yarn fabrics should be quickly dried flat after washing and dehydration to reduce wrinkles. In addition to white fabrics, do not expose to the sun, avoid accelerating the oxidation of cotton cloth due to exposure, thereby reducing the service life of clothes and causing fading and yellowing. When airing in the sun, it is recommended that the inside be aired outward.
Cotton thread identification method
Cotton yarn and cotton cloth is the general name of all kinds of cotton textiles. It is mostly used for fashion, casual wear, underwear and shirts. The advantages of cotton yarn and cotton cloth are easy to keep warm, soft and close to the body, good moisture absorption and air permeability. Compared with chemical fibers, cotton fibers have good heat preservation, moisture absorption and softness, and there is no electrostatic effect on cotton fibers. However, due to the weak elasticity and wrinkle resistance of cotton and hemp fibers, clothing is simply wrinkled and uncomplicated in the process of wearing and washing, which brings many inconveniences to consumers in the ordinary clothing management. Shirts are made of pure cotton yarn-dyed fabrics. The unique ironing-free cleaning skills of the company are used together to make the products have both pure cotton characteristics and excellent wrinkle resistance. The shirts are blended with hemp, bamboo and silk fibers, which have functions and practicability and greatly meet the modern fast-paced life style.
Chemical fibre fabrics are wear-resistant, wear-resistant, wrinkle-resistant and stiff, but they are far less comfortable than pure cotton fabrics, and have adverse reactions that can cause red skin. So the old man and children should use pure cotton as much as possible to get clothes, especially underwear and bedding, in order to improve their health. With the progress of people's living standards, health care, yearning for returning to nature, cotton thread, a natural fibre thread, like green food, is becoming more and more popular. Therefore, nowadays, the price of pure cotton yarn fabric is significantly higher than that of chemical fibre fabric, whether at home or abroad.

It is a fiber from cottonseed, which is picked and disposed, rolled cotton, carding, stripping, combed, woolen, worsted into cotton yarn, and then woven into cotton cloth from cotton yarn.
1) Advantages of pure cotton yarn:
Pure cotton yarn has strong hygroscopicity - cotton yarn is a porous material, the internal molecules are arranged irregularly, and there are many hydrophilic layouts in the molecules.
Warmth retention of pure cotton yarn - cotton yarn is a bad conductor of heat, and the inner cavity of cotton fibers is filled with inactive air.
Cotton thread is comfortable to wear - no static electricity, excellent air permeability, anti-sensitive, simple and clean.
2) Pure cotton yarn defects:
Pure cotton yarn wrinkles easily - cotton fibers have poor elasticity.
Cotton yarn shrinkage rate is large - cotton fiber has a strong water absorption, when it absorbs moisture, the cotton fiber swells, resulting in shortened cotton yarn deformation.
Pre-washing Scale of Pure Cotton Yarn--Post-washing Scale of Pure Cotton Yarn
Attached Accounting Method: Shrinkage Rate=*100%
Pre-washing Scale of Pure Cotton Yarn
Normally knitted garments withstand a shrinkage of +5%.
Mildew of pure cotton thread - In a wet state, in case of bacteria or fungi, the cotton thread will be decomposed into their favorite nutrient - glucose, which will make the fabric mildew and degenerate.
If cotton fibers are touched by sunlight for a long time, their strength will decrease, and the fibers will become brittle and brittle. When exposed to oxidants, bleaching powder or oxidizing dyes, the strength of cotton fibers will also be reduced and the fibers will become brittle and hard.
3) Washing method of pure cotton yarn:
Pure cotton yarn can be washed by machine or by hand, but because of the poor elasticity of the fibers, it is best to wash it lightly or not by hand vigorously, so as to avoid clothes changing and affect the scale.

5) Cotton yarn ironing: high temperature resistance, can be used to ironing high temperature to 200CO.
Pure cotton yarn features: pure cotton yarn is soft and tough, not luster, rich in moisture absorption, good air permeability, comfortable to wear. Washing resistance, good dyeing.
Defects of pure cotton yarn: pure cotton yarn fades, wrinkles easily, and shrinks when washed.
