In Ready-made garments – during the dyeing ,washing procedure several substances could present in finished garments, which cause health hazards and are banned world wide. If any of below substances are found during the final garments test procedure then garments seller must bear a penalty for that.
Azo dyes are dyes which contain at least one azo bond (-N=N-) within the molecule. In textiles and apparels, azo dyes are commonly used as colorant. Certain azo dyes, when in a basic chemical environment or under certain enzyme conditions, can release harmful aromatic amines. Some of these aromatic amines are classified as carcinogens.
DISPERSE DYES (Which are classified to be allergenic) :
Disperse dyes are generally water-insoluble colorants that are mainly used for coloring polyester, nylon and cellulose acetate textile fibers. They have extremely high light fastness for very pale colors. Some disperse dyes have an allergenous (sensitizing) potential to human skin and can be considered as a possible threat to health, especially if the dyes exhibit poor perspiration fastness.
DYES (Which are classified to be carcinogenic):
Although the discussions of genotoxic substances in textiles in recent years have focused on azo dyes splitting off carcinogenic amines, the classification of carcinogenic dyes should not be limited to those azo dyes. These textile dyes classified by their nature may also give rise to mutagenic effects.
Biocides are biologically active substances, and their toxic and biocidal nature enables them to kill or harm living things. Since biocides by nature are used to have detrimental effects on biological organisms, they are at the same time a serious threat to living organisms that were not intended to be controlled. Biocides have adverse effects on the nervous system when entering into the human body. They may irritate eyes, skin, and the respiratory system. Dimethylfumarate (DMFu) is applied to prevent mildew/mould. It is a contact allergen and is able to cause allergenic reactions, even in the smallest concentrations, like fierce eczemas or burn injuries.
