It is an old tradition to add new clothes during the Chinese New Year, but it is best to soak them in salt water and wash them before wearing them when you buy them. Because new clothes may have residual carcinogens —— formaldehyde during anti-wrinkle treatment.
We sometimes find a odor on new clothes, which is formaldehyde, which is used to deal with the disadvantages of wrinkles in cotton. Under high pressure and high temperature environments, combining formaldehyde molecules with cotton fiber molecules can produce anti-wrinkle effects. However, if the processing process is not rigorous enough, or if the cleaning is not cleaned after treatment, the formaldehyde monomer will be released from the fabric, and even the fabric itself has formaldehyde.
According to studies, formaldehyde can also cause cancer in addition to causing diseases such as cough and allergic rhinitis. Salt can disinfect, sterilize, and prevent cotton cloth from fading, so it is best to soak it in salt water before wearing new clothes. This way, the new clothes are healthier and safer to wear.
How long do new clothes be soaked in salt water? Before washing, soak the clothes in salt water for about half an hour, then remove them to wash, so that they will not fade, but the salt water does not have to be too thick.
