Little knowledge about the washing of various fiber textile fabrics

Little knowledge about the washing of various fiber textile fabrics:
1) Cotton fabric
Cotton fabrics have strong alkali resistance, acid resistance and high temperature resistance, and can be washed with various soaps or detergents. Before washing, it can be soaked in water for a few minutes, but it should not be too long to avoid color damage. The intimate underwear should not be soaked in hot water, so as to prevent the protein in the sweat stains from coagulating and adhering to the clothing, and yellow sweat spots will appear.
When washing with detergent, the preferred water temperature is 40~50 ℃. When rinsing, the method of "a small amount of water for many times" can be mastered, that is, it is not necessary to use a lot of water for each rinse; But wash it several times. After each washing, it should be screwed dry and then washed to improve the washing efficiency. The clothes should be dried in a ventilated and cool place to avoid exposure to the sun and fading the colored fabric.
2) Ramie fabric
The hemp fiber is rigid and has poor cohesion. When washing, it should be lighter than cotton fabric. Do not use a hard brush and rub hard to avoid fuzzing on the cloth surface. Do not twist hard after washing, do not use hot water to soak colored fabrics, and do not expose them to the sun to avoid fading.
3) Silk fabric
洗涤之前，将水浸泡约10分钟，浸泡时间不应该太长。请勿用碱性水洗涤，而要使用中性肥皂或肥皂片或中性洗涤剂。洗涤溶液应略有或在室温下。洗涤后，轻轻挤压水，避免扭曲。它应该在凉爽且通风的地方干燥。它不应暴露在阳光下，也不应干燥。
4) Wool fabric
Wool is not alkali resistant, so it should be washed with neutral detergent or soap. Wool fabrics will shrink and deform in aqueous solution above 30 ℃, so the washing bath temperature should not exceed 40 ℃. The detergent aqueous solution is usually prepared with room temperature (25 ℃) water. When washing, do not use a washboard to wash, that is, use a washing machine to wash, and should wash gently, and the washing time should not be too long, to prevent shrinking.
Do not wring after washing, squeeze the water by hand, and then drain. Dehydration by washing machine should take half a minute. It should be dried in a cool and ventilated place, not in strong sunlight, so as to prevent the fabric from losing its luster and elasticity and causing the loss of strength.
5) Viscose fabric
Viscose fiber has high shrinkage rate and low wet strength. It should be washed and soaked at the same time. It cannot be soaked for a long time. Viscose fabric will harden in water, so it should be washed gently to avoid fuzzing or cracking. Use neutral detergent or low-alkali detergent. The temperature of washing solution shall not exceed 45 ℃. After washing, fold up the clothes, squeeze out the water by a large amount, and avoid twisting. Do not expose to the sun after washing, but dry in a cool or ventilated place.
6) Polyester fabric
Soak it in cold water for 15 minutes, and then wash it with general synthetic detergent. The temperature of the detergent should not exceed 45 ℃. Dirty places at the neckline and cuffs can be brushed with a brush. After washing, rinse it, twist it gently, dry it in a cool and ventilated place, do not expose it to the sun, and do not dry it to avoid wrinkles due to heat.
7) Acrylic fabric
Basically similar to polyester fabric washing. Soak it in warm water for 15 minutes, and then wash it with low-alkali detergent. Gently rub it. The thick fabric is washed with a soft brush, and then dehydrated or slightly twisted. Pure acrylic fabrics can be dried, but blended fabrics should be dried in a cool place.
8) Nylon fabric
Soak it in cold water for 15 minutes, and then wash it with general detergent (regardless of alkali content). The washing solution temperature should not exceed 45 ℃. After washing, it should be ventilated and dry, and not exposed to the sun.
9) Vinylon fabric
Soak it in room temperature water first, and then wash it at room temperature. The detergent is ordinary detergent. Do not use hot boiled water to avoid the expansion and hardening of vinylon fiber, or even deformation. Dry after washing to avoid sun exposure.
