Things You Need to Know About Elastane

Stretch, stretch, hold and back to the starting position - no, this is not about the best stretching exercises for your workout. But it's about a fiber that's pretty much always involved and is pretty much guaranteed to outperform you: spandex. The synthetic fiber, also known as "Lycra" or "Spandex", is added to almost all sportswear and ensures the best performance, fit and comfort. Why this is so and what reasons speak for or against spandex as an ingredient for sportswear, you will learn here.
1. Where does the name spandex come from? As the name suggests, spandex is enormously stretchable. The main component of the synthetic fiber is polyurethane, a synthetic raw material that is as stretchy as rubber. This allows spandex to be stretched by up to 700 percent without wearing out: the fiber always returns to its original shape undamaged. A remarkable stretching exercise, which makes spandex the perfect material for precisely fitting sportswear that puts away all movements unscathed.
2. Spandex: No creasing, no "pilling" The smooth, rubber-like texture ensures that spandex fabrics are extremely durable and do not wrinkle. They also do not lint and no unsightly nodules form - a wear process called "pilling".
3. Elastane is breathable After the rubber comparison, this property of the synthetic fiber is even more amazing. The smooth spandex fibers absorb little moisture and dry quickly again. Thus, clothing made of spandex never looks uncomfortably wet. However, there is one disadvantage: the synthetic fiber develops unpleasant odors more quickly than it's the case with natural fibers. However, there are already innovative coatings that prevent perspiration odors.
4. Spandex is always only elastic accessory Artificial fibers do not feel as comfortable on the skin as natural fibers. That's why spandex is only ever added to fabrics to make snug-fitting and elastic fabrics, and not used exclusively for fabric production. The proportion is usually less than 30 percent and endows cotton fabrics, for example, with stretchy capabilities. Stretch jeans, socks or yoga pants are a good example. However, spandex not only works well in the mix with sustainable natural fibers, but is also readily found in super stretchy blended fabrics with other synthetic fibers, for example for neoprene suits, swimwear or cycling clothing.
5. The basis of spandex is petroleum The sporty fiber is created in the chemical laboratory on a synthetic basis. According to the EU Textile Labeling Regulation, it must consist of at least 85 percent polyurethane, a material derived from the non-renewable raw materials crude oil and natural gas. The production requires a huge amount of energy and the resulting intermediate products are problematic for the environment.
6. Spandex can hardly be recycled While environmentally friendly recycling processes already exist for regenerative natural fibers such as cotton, merino wool or linen, it has not yet been possible to develop a mature process for recycling synthetic materials such as spandex. Also problematic is that through the wear of the textiles, tiny particles from the synthetic fibers enter nature as microplastics.
7. Laundry nets protect the environment A large part of the wear and tear happens in the washing machine: microparticles are released from the spandex fabric during the wash cycle and enter the wastewater. They are so small that they are not filtered out even in the sewage treatment plant. As a result, they end up directly in rivers, lakes and oceans, and ultimately in fish, mussels and aquatic plants. To curb this pollution, you should definitely wash your spandex-containing sportswear in special laundry bags that collect the microplastics.
