Some friends are very diligent and always wash their clothes after they are soaked. In fact, this approach is not scientific. Generally speaking, it is best to soak clothes in cold water for a while before washing. This has several advantages:
(1) It can make the dust and sweat attached to the surface of the clothing separate from the clothes and enter the water, which can not only improve the washing quality of the clothes, but also save detergent. The penetration of water can be used to make the fabric fully expand before it enters the washing solution, so that the dirt in the cloth eye is squeezed out and floats on the surface, making it easy to remove.
(2) Some dyed fabrics with poor washing fastness are easy to decolorize, and pre-soaking can detect these problems in time, making it easier to take preventive measures during the washing process. The amount of water for soaking the clothes should be sufficient, and the soaking time should be determined according to the variety, material, new and old, dirty and dyeing fastness of the clothes. Generally speaking, down jackets take 5-10 minutes, synthetic fiber clothing 15 minutes, worsted wool clothing 15-20 minutes, coarse wool clothing 20~30 minutes, blankets and woolen clothes 20 minutes.
