Common sustainability problems in swimwear

For those of us who spend our whole lives outside, including myself, it's easy to overdo it by stuffing our drawers with the newest fashion statement. But sadly, swimwear also has another issue with sustainability in addition to falling victim to the quick fashion cycle: plastic.

Because they remove moisture from the body and stretch to fit the body, synthetic materials like nylon, polyester, and spandex are ideal for swimwear because they lessen friction in the water. The fashion industry mainly relies on them since they are also adaptable and affordable to produce, used not only for swimwear but also for activewear, outerwear, and other low-cost, fast-fashion clothing.

This is a significant concern because plastic never decomposes, which makes it problematic throughout the whole production process, from the release of microfibres during washing to the disposal of the garment at the end of its useful life.

Fortunately, the finest method for maintaining your swimwear—gentle hand washing—is also the best method for minimising microfibre emissions. Additionally, it makes the most sense because swimwear is typically worn for a relatively little length of time and shouldn't frequently need to be machine washed!

Eco-friendly bikini materials

Thankfully, there are alternatives to the harmful polymers that are used to make the majority of swimsuits.

Eco-friendly materials, like ECONYL, developed by the Italian company Aquafil, employ synthetic waste, including waste fabric, fishing nets from the ocean, industrial plastic, and waste textiles, and recycle and regenerate them to make new nylon yarn that is precisely the same quality as virgin nylon.

Even better, other swimsuit companies are addressing this demand by inventing and producing their luxurious materials from recycled nylon fibres or other natural substitutes.
