I wear mostly natural fibres but occasionally have problems with elasticine. I thought this referred to elastic. So when the label said 95% cotton 5% elasticine I thought the article of clothing contained elastic. I was kind of confused to find my jeans contained elastic but considered it essential in my knickers. Obviously more research was needed.
What is elasticine? also called Spandex or Lycra
elastane is a synthetic fiber known for its exceptional elasticity. It can be stretched up to 7 times it’s own length and snaps back into shape. So yes like elastic in that sense.
BUT rather than a stretchy piece of white stuff threaded through your waistband, it is used in a blend with other fibres. It is often mixed with natural fibres such as cotton to help them keep their shape.
There are two principal methods used in processing elastane. One is to wrap the elastane fibre in a non-elastic thread – either natural or man-made. The resulting yarn has the appearance and feel of the outer fibre used. The second method involves using pure elastane threads, which are worked or woven into fabrics made from other fibres. The added elasticity makes such fabrics more comfortable to wear. Blends with elastane depend on the type of fabric and the end use.
On care labels elastane is often designated as “EL”.
For cotton clothes that need a lot of stretch like socks and knickers it is almost impossible to find them elasticine free.
Why is this a problem?
It is a polyether polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPonts Wikipedia
Basically it is a non biodegradable plastic. The problem with non biodegradable plastic fibres is that they shed when the fabric containing them is washed. They are then swooshed into the drains in the waste water and, too fine to be filtered out, they end up the rivers and sea. Once there, being plastic, they don’t biodegrade. They are now amongst other problems, being eaten by plankton with worrying effects.
And then there is this….”Spandex is made from several chemicals that are known sensitizers. TDI and MDI (Toluene-2,4-diisocyanate; Methylene bisphenyl-4,4-diiisocyanate) are precursors of the polyurethane used to make spandex. TDI, a toxic chemical, has proved carcinogenic and can cause severe dermatitis. MDI is also toxic. Manufacturers of spandex products must use strict quality control procedures to ensure that no residual unreacted MDI or TDI exists in the final product.
Why I boycott….
Seemingly, wherever scientists look, they’re finding plastic fibers contaminating the environment. Often, plastic textile fibers are the dominant source of plastic pollution found in surveys. Plastic fibers have been found in the sediment surrounding beaches, in mangrove groves, and in Arctic ice — even in products we eat and drink. “The average person ingests over 5,800 particles of synthetic debris” a year, a recent paper in PLOS finds. And most of those particles are plastic fibers.
