After a large number of clothes are discarded, they cannot be completely degraded, which causes great pressure on the environment. At the same time, more and more attention has been paid to the pollution of plastic micro particles, and we urgently need an effective solution. InnoTech-Fi technology enables ordinary chemical fibers to obtain the ability of biodegradation, so as to realize the natural cycle from nature and back to nature. During the wearing and storage process, the performance of the fiber obtained by InnoTech-Fi technology is very stable, and only in the anaerobic environment such as landfill and the extremely rich microbial environment, can it start to biodegrade. The degradation rate can be tested by ASTM D5511.
