The vast majority of swimsuits on the market are made of synthetic fibers - because synthetic fabrics possess the elasticity and durability required for swimsuits, as well as resistance to chlorine, salt water, and sunlight.

However, synthetic fabrics come at the cost of the environment, as their production requires a large amount of energy and oil, and in the process, non degradable waste is generated.

However, with the advancement of technology, some clothing fabrics can be recycled, and using fabrics made from secondary recycling can reduce the demand for crude oil.

However, synthetic fabrics - whether or not recycled - will shed microfibers during washing, and these microfibers still pollute our ecological environment. For the definition of environmental protection, using recycled fabrics is only relatively environmentally friendly.
