Little knowledge about the washing of various fiber textile fabrics:

1) Cotton fabric

Cotton fabric has strong alkali resistance, acid resistance and high temperature resistance. It can be washed with various soaps or detergents. Before washing, soak it in water for a few minutes, but not too long to avoid color damage. Close fitting underwear can not be soaked in hot water, so as not to solidify the protein in the sweat stain and adhere to the clothing, and yellow sweat spots will appear.

When washing with detergent, the better water temperature is 40 ~ 50 ℃. When rinsing, you can master the method of "small amount and many times", that is, you don't have to use a lot of water for each rinse; But wash it a few more times. After each washing, it shall be screwed dry and then washed to improve the washing efficiency. The clothes shall be dried in a ventilated and cool place to avoid exposure to the sun and discoloration of colored fabrics.

2) Hemp fabric

Hemp fiber is rigid and has poor holding force. It should be lighter than cotton fabric when washing. Do not use a hard brush and rub hard to avoid fuzzing on the cloth surface. Do not twist hard after washing. Colored fabrics should not be soaked in hot water. They should not be exposed to the sun to avoid fading.

3) Silk fabric

Before washing, soak in water for about 10 minutes, and the soaking time should not be too long. Do not wash with alkaline water. You can choose neutral soap or soap tablets and neutral detergent. The lotion should be slightly warm or room temperature. After washing, gently squeeze the water and avoid twisting. It should be dried in a cool and ventilated place, not exposed to the sun, let alone dried.

4) Wool fabric

Wool is not alkali resistant, so it should be washed with neutral detergent or soap. Wool fabric will shrink and deform in aqueous solution above 30 ℃, so the washing bath temperature should not exceed 40 ℃. Usually room temperature (25 ℃) water is used to prepare detergent aqueous solution. When washing, do not scrub with washboard, that is, wash with washing machine. It should be washed gently, and the washing time should not be too long to prevent cashmere shrinkage.

Do not twist after washing, squeeze by hand to remove water, and then drain. It is advisable to dehydrate with a washing machine for 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 luster and elasticity and causing the decline of strength.

5) Viscose fabric

Viscose fiber has large shrinkage and low wet strength. It should be soaked with washing and can not be soaked for a long time. Viscose fiber fabric will harden in case of water. Wash it 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 and squeeze out the water in large quantities. Do not twist them. Do not expose to the sun after washing. It should be dried in a cool or ventilated place.

6) Polyester fabric

First soak in cold water for 15 minutes, and then wash with general synthetic detergent. The temperature of the washing solution should not exceed 45 ℃. The dirty part of the collar and cuff 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. First soak in warm water for 15 minutes, and then wash with low alkali detergent. Knead and rub gently. The thick fabric shall be washed with a soft brush, and then dehydrated or slightly twisted to remove water. Pure acrylic fabric can be dried, but blended fabric should be dried in a cool place.

8) Nylon fabric

First soak in cold water for 15 minutes, and then wash with general detergent (no matter the size of alkali). The washing liquid temperature should not exceed 45 ℃. After washing, ventilate and dry in the shade. Don't dry in the sun.

9) Vinylon fabric

First soak it in room temperature water, and then wash it at room temperature. The detergent is ordinary washing powder. Do not use hot boiled water to avoid expansion, hardening and even deformation of vinylon fiber. Avoid drying after sun washing.
