Most of us wear clothes made of synthetic fiber because it is hassle-free to maintain. Others wear cotton or linen because they are cooler and congenial. Invariably, when we buy new clothes we wear them before first wash. It is a bad practice because there are some issues relating to our skin health.
The so-called ‘disperse dyes’ are used in polyester fiber dyeing. Even if we buy 100% cotton wear, we do not know what chemicals are used in dying. The dyes, particularly disperse dyes, can irritate skin and cause Allergic Contact Dermatitis. This inflammation may appear immediately or after few weeks. The sweat and friction may cause disperse dyes to leak out onto the skin. Washing them immediately after purchase will wash out those little extra dyes on new clothes, which will lessen the risk. Usually, the neck area and armpits are at greater risk. Some people experience allergy for years as the immune system is compromised.
Research at the Stockholm University in Sweden found ‘quinoline’ in 29 of the 31 samples of new clothes. This is high in polyester garments. Quinolone was classified as 'a possible human carcinogen’ by the US Environment Protection Agency. Nitroanilines and benzothiazoles are also found in dyes, which have potential adverse effects on human health.
