Biomass materials

Biodegradable refers to materials that can be decomposed by microorganisms into natural elements and then returned to nature. Among clothing materials, natural fibers such as cotton, hemp, silk, wool, etc. are biodegradable, and the decomposition time ranges from several months to several years. Man-made fibers are mainly polyester, nylon, spandex, etc., which are commonly found in sportswear, sweaters, thermal underwear, etc. Man-made fibers are extracted from petrochemicals, which are equivalent to plastics and take hundreds of years to decompose.
