production process

safety production technology

the polyester regenerated technology of grerial environmental protection is from the independent research and development of the company. the technical route is that the waste polyester is depolymerized to bhet under the action of ethylene glycol, temperature and pressure. bhet is sent to the polyplant after being filtered and purified for the polymerization of polyester. when the company strives to make the technological breakthrough and technical exploration, we have developed our own alcoholysis chemical regeneration technology. related patents have been applied for, among which three patterns for utility models related to pre-fragmentation and pretreatment have been authorized, and one patent for invention has been applied for; a total of five patterns related to chemical recycling additive adding, decolorization and polymerization of the waste textiles are currently in the review stage.

security/authentication

the company has passed the certification of green fiber mark, iso 9001:2008 international quality management system, iso 14001:2004 international environmental management system, ohsas 18001 occupational health and safety management system, grs: global standard, etc. the products have passed the certification of european union confidence textiles (grade ii: direct skin contact) international intertek carbon footprint certification and renewable components certification, and has established a "hospital". scholar expert workstation ", in full cooperation with academician yu jianyong's team, undertook the" national key research and development program - chemical regeneration polyester fiber preparation technology ".
