Little knowledge of these four categories of textiles

At present, there are still four types of garments that have excessive levels of formaldehyde in the market:

One, non-iron clothing

Because the garments that need to be finished are iron-free, formaldehyde-free finishing agents may be used, and some of these products have high levels of formaldehyde.

Second, cowboy clothing

The use of formaldehyde may be used during the manufacture of the cowboy's resin finish (as in the setting of creases), posing a hazard to the body.

Third, the textile products containing fusible lining

The bonding of the fusible interlining to the fabric mainly depends on the adhesive strength of the adhesive, and the adhesive is usually an amide reacted with formaldehyde to form an N-methylol amide polymer, which is in the cellulose macromolecule or its basic Covalent linkages are formed between the structural units, and the crosslinked covalent bonds are hydrolyzed to generate free formaldehyde under certain temperature and humidity conditions, which may cause excessive formaldehyde content in the fabric.

Fourth, paint printing textile products

The various color fastness properties of paint printing products depend on the properties of the adhesive, whereas formaldehyde-containing adhesives have better adhesive properties and therefore release formaldehyde during their reaction with the fibers. In addition children's clothing due to higher requirements so that formaldehyde content exceeded.

With the gradual approach of green, safety, and environmental protection as the mainstream concept of consumption, the problem of formaldehyde in textiles is increasingly drawing attention from domestic manufacturers, the commercial sector, and consumers. In this regard, relevant professional manufacturers should increase their efforts to conduct research on formaldehyde-free or low-formaldehyde treatment auxiliaries and processes. Textile manufacturers should avoid the use of formaldehyde-containing raw materials, additives or processes for production, that is, control from the source. Consumers should also refuse to purchase such clothing. For newly purchased children's clothing or clothing that has been placed in the closet for a certain period of time, it is best to wash it with clean water before wearing it and fully dry it before wearing it.
