Washing method of polyester and cotton

When washing polyester and cotton fabrics, we can use various detergents, which can be washed by hand or by machine. However, due to the poor elasticity of cotton fibers, we should not use strong scrubbing when washing, so as not to deform the clothes and affect the size.
If it is white clothes, it can be washed at high temperature with strong alkaline detergent to play a bleaching role. The underwear can not be soaked in hot water to avoid yellow sweat spots. It is better to wash clothes of other colors with cold water, and do not use detergent or detergent containing bleach to avoid discoloration, and do not pour detergent directly onto cotton fabric to avoid partial discoloration.
