Newly bought close-fitting clothes need cleaning, and clothes similar to coats can be worn directly. Experts pointed out that newly bought clothes must be cleaned before wearing, and it is best to soak them in salt before cleaning. Because formaldehyde, a chemical used in anti-wrinkle treatment, may remain on new clothes. Everyone may have encountered such a situation. There is always a bad smell on newly bought clothes, and this bad smell mainly comes from the chemical component formaldehyde. In the environment of high temperature and high pressure, formaldehyde molecules and cotton fiber molecules cross-link and combine, thus producing anti-wrinkle effect. However, if the treatment process is not rigorous enough, or the cleaning after treatment is not clean, formaldehyde monomer will be released from the cloth.
Moreover, formaldehyde is very harmful and bad for human health. However, formaldehyde is soluble in water. Formaldehyde can be removed from newly bought clothes as long as they are washed and worn. Especially close-fitting clothes, it is necessary to wash them several times to remove some harmful residues.
According to experts, formaldehyde is a volatile substance with good water solubility. Formaldehyde not only causes acute eye symptoms, cough, tears, visual impairment and rash, but also has certain carcinogenicity.
