In the process of polyester spinning production, organic biodegradable masterbatch is added in a certain proportion to make degradable polyester fiber, which accelerates the degradation of polyester fiber in the landfill full of anaerobic organisms (landfill or deep sea), and will not be affected by water washing, dyeing and finishing and lose its degradation effect

In the process of polyester spinning production, organic biodegradable masterbatch is added in a certain proportion to make degradable polyester fiber, which accelerates the degradation of polyester fiber in the landfill full of anaerobic organisms (landfill or deep sea), and will not be affected by water washing, dyeing and finishing and lose its degradation effect

An organic biodegradable masterbatch, which is a general accelerator for natural degradation of polyester based on the principle of directional bionics and quorum sensing. As long as a certain proportion of organic biodegradable masterbatch is added to the existing common polyester, the natural degradation of deep polyester can be stimulated under appropriate conditions to meet the specification requirements of polyester degradation products. According to the report of international testing institutions, the degradation rate of high solid anaerobic environment is 7.26% in 45 days, 94.5% in 309 days, and 56.1% in 441 days under marine conditions. The outstanding advantage of this product is that it does not change the process and parameter conditions of the downstream processing and production of commonly used polyester, does not need to invest in the purchase of any new major production equipment, maintains the product quality of commonly used polyester, does not affect the repeated recycling and reuse, and fully meets the requirements of garbage classification and green, low-carbon and circular development
