Description

technical field

[0001] The invention relates to a method for directly preparing fiber products from a polylactic acid polymer melt, and belongs to the technical field of polymer material applications. Background technique

[0002] Polylactic acid is a new biodegradable polymer material that uses renewable starch or glucose as the initial raw material and is finally polymerized through multiple preparation processes. It was officially industrialized in the United States in 2002. The trade name is PLA. my country is in the research and development stage and has not yet entered Industrial production.

[0003] At present, individual manufacturers in our country are trying to prepare fiber products from the polylactic acid polymerization melt obtained by the polymerization reaction of the polymerization reaction device. The method is as follows: first, put lactide and additives into the polylactic acid polymerization reaction device for polymerization reaction The obtained polyla...
