With back to school comes new clothes shopping, so we thought we’d re-post this important blog. Keep reading to find out why it’s so important to wash before you wear.
There are three good reasons to wash new clothes, especially those that are worn in direct contact with your skin, before you wear them.
One is to wash out extra dye that can be transferred to your skin or other garments. Most fabric made from synthetic fibers (polyester, acrylic) are colored with azo-aniline dyes. These dyes can cause severe skin reactions for those who are allergic to them. If the allergy is severe, the rash will be similar to poison ivy. But even less severe reactions can cause dry, itchy inflamed patches of skin.
It is possible to transfer lice, scabies, bacteria and fungus from person to person when clothes are tried on. Dressing rooms can become breeding grounds for everything from viruses to athlete’s foot.
And, most importantly, to remove the chemical finishes that manufacturers put on clothes to enhance color or texture. The finishes won’t bother everyone, but if you have sensitive skin you can develop a rash especially in constant contact areas like armpits, collars, cuffs and trouser waists and thighs.
Urea formaldehyde is often the chemical used to prevent mildew on clothes that have to be shipped long distances in hot, humid containers from overseas to the United States. It has a very strong odor that will remain in the fabric until the garment is washed. One washing will not remove formaldehyde completely but you will reduce the build up significantly and it will continue to be removed with each wash.
It is especially important that children’s clothing, especially clothes for babies, be washed before they are worn. Babies are particularly sensitive to chemicals and skin rashes can occur. Select a detergent that is fragrance free and dye free as these can also cause skin reactions. Washing the clothes for children will also make them softer and more comfortable for them to wear.
Washing new sheets/blankets and towels is also important to remove chemicals since these come in direct contact with skin. Washing will also improve the absorbency of the fabric by removing surface fiber coatings.
If you have a tag on the garment that reads “wash separately before wearing”, beware of dye transfer and color bleeding. Washing will help remove the excess dye but check the rinse water. If color remains in the water, it make take several wash cycles to get rid of the excess dye so continue to wash separately or with similar colors.
