Classification of environmental protection in washing industry

According to the definition and classification of washing industry, washing is a reversible process, and dirt removed from fabric may return to fabric. A substance that can properly disperse the removed dirt in the washing liquid and never return to the surface of the fabric is called an anti-redeposition agent. Soap has good redeposition resistance, while anionic surfactants such as sodium alkylbenzene sulfonate have poor redeposition resistance.

1, Wash by color: first pick out the dark and bright clothes, because the dark clothes may fade, and if the light clothes are washed together, they will be dyed, which will affect the beauty of the light clothes.

2. Washing by thickness: thin clothes such as mesh cloth, silk fabrics, underwear, knitwear and socks are easy to deform. In order to avoid damage, it is best not to wash them by machine, but by hand.

3. Washing according to fiber raw materials: fabrics containing plush or other special fabrics are easy to shrink and deform, so it is not suitable for washing with water, and should be picked out for dry cleaning.
