1、 Cotton fabric
Cotton fabric has 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 underwear should not be soaked in hot water to prevent the protein in the sweat stains from solidifying and adhering to the clothes, thus causing yellow spots. The optimal water temperature is 40~50 ℃ when clothing detergent is used. When rinsing, you can master the method of "a small amount of water for many times", that is, you may not use a lot of water every time you rinse with clean water; But wash it more often. After each rinse, it shall be screwed dry and then rinsed for a second time to improve the washing efficiency. The clothes should be dried in a ventilated and cool place to avoid exposure to strong sunlight, which will fade the colored fabric.
2、 Flax fabric
Hemp fiber is rigid and has poor cohesion. When washing, the force should be lighter than that of cotton fabric. Do not use a stiff brush to brush and rub hard, so as to avoid fabric fuzzing. After washing, do not twist the colored fabric. Do not soak the colored fabric in hot water. Do not expose it to strong sunlight to avoid fading.
3、 Silk fabric
Before washing, soak the clothes in water for about 10 minutes, and the soaking time should not be too long. Avoid washing with alkaline water, and use neutral soap, washing powder or neutral detergent. Bathing liquid should be at low temperature or room temperature. After washing, gently squeeze the water and avoid twisting. It should be dried in a cool and ventilated place. It should not be exposed to strong sunlight, let alone dried.
4、 Wool fabric
Wool is not resistant to alkali, so it should be washed with neutral detergent. Wool fabric will shrink and deform in the aqueous solution above 30 ℃, so the washing water temperature should not exceed 40 ℃. The washing solution is usually prepared with room temperature water (25 ℃). When washing, do not use washboard to wash, that is, use washing machine to wash. It should be "lightly washed", and the washing time should not be too long to prevent cashmere. Do not wring after washing, squeeze with your hands to remove water, and then drain. The washing machine should be used for dehydration for half a minute. It should be dried in a cool and ventilated place, not in strong sunlight, to prevent the fabric from losing luster and elasticity and causing the decline of fabric strength.
5、 Viscose fabric
Viscose fiber has large shrinkage rate and low wet strength. It should be soaked when washing, and it cannot be soaked for a long time. Viscose fabric will harden when it meets water, so it should be washed gently to avoid fuzzing or cracking. Use neutral detergent or low alkaline detergent. The temperature of washing solution shall not exceed 45 ℃. After washing, fold the clothes, squeeze out the water in a large amount, and never twist them. Do not expose to the sun after washing, and dry in a cool and ventilated place.
