    AZO dyes testing

    The AZO dyes (or the decomposition of aromatic amine dyes) will decompose and produce carcinogenic substances and damage human health. Moreover, these colorless and odorless dyes cannot be perceived by human sensory organs and it even can not be eliminated through washing, etc. Thus, these types of dyes are banned in textile standards all over the world.
    PONY suggests that corresponding manufactures should use AZO-free dyes from raw materials and during textile manufacturing in order to avoid unnecessary losses in sales market or exportation due to containing prohibited aromatic amines in the final products.

    1 Clothing, bedding, towels, wig, fake eyebrows, hats, diapers and other cleaning supplies, sleeping bags
    2 Shoes, gloves, handbags, watches, purses, briefcases, chairs sets

    4 Fabric and yarn for using by consumers
