Abstract

The invention relates to a production method of PLA(polylactic acid) wool-like fiber. The production method comprises the following steps: firstly, drying a polylactic acid raw material, then enablingthe dried polylactic acid raw material to enter into a screw extruder for fused compression, then enabling the fused and compressed polylactic acid raw material to enter into a spinning component, spraying out tows through the spinning component, cooling the tows through a cross air blasting device and a paved path, then oiling the tows through an oiling device and drafting through a drafting component, and after entering into a main interlacer, enabling the drafted tows to enter into a coiler for coiling. The production method provided by the invention is beneficial to effective promotion ofthe PLA wool-like fiber.

Description

technical field [0001] The invention belongs to the technical field of textile chemical fiber production, and in particular relates to a production method of PLA polylactic acid wool-like fiber. Background technique [0002] Polylactic acid (English full name: polylactic acid, referred to as PLA) fiber, the raw material polylactic acid used comes from plants, non-fossil fuels, the fiber is naturally degradable, and has a silk-like luster and feel, and has a certain water absorption. Very good fiber material with great development potential. [0003] In the prior art, wool-like fibers are mainly prepared from polyamide or polyethylene terephthalate (PET) or polybutylene terephthalate (PBT). However, the wool-like fibers made of these materials are difficult to degrade in the soil, and once discarded randomly, it is easy to cause environmental pollution. Therefore, the use of polylactic acid to manufacture wool-like fibers is on the agenda. [0004] At present, there are not...
