Recently, FILA (Italian fashion sports brand) launched a “natural symbiosis T” T-shirt, each T-shirt using low-energy dyeing process and biodegradable materials. The main fabrics are all made of biodegradable fibers: 60% cotton + 40% CELYS™ polyester, and the woven labels, combinations of labels, and back neck tapes, including seams, are all made of materials containing biodegradable natural fibers, to implement energy-saving and carbon-reducing initiatives in a small way. This Sallis® polyester fiber can be degraded into water, carbon dioxide and biomass fertilizer under industrial composting conditions, returning it to nature, reflecting FILA's “From Nature To Nature” environmental protection concept.
Polyester fibers, commonly known as polyester, are used for traditional clothing. Ordinary polyester material will not degrade for hundreds of years, but will only fragment over time, resulting in a large amount of microplastics. Once formed, microplastics cannot be eliminated by any known technology. Therefore, creating a biodegradable polyester material to replace the non-biodegradable traditional functional fibers became the only solution. Scientists from Australia, after seven years, finally succeeded in creating CELYS™ biodegradable polyester materials and fibers in 2021, and got the certificate of industrial compost degradation certification in EU and North America! According to the composting test report from Rheinland Laboratories, the degradation rate of CELYS™ fiber is as high as 95.4% in 179 days! This means that for the first time the textile polyester industry finally has a solution to reduce the production of microplastics.
