Abstract

The invention relates to a production method of PLA(polylactic acid) moisture wicking silk-like fiber. The production method comprises the following steps: firstly, drying a PLA raw material, then enabling the dried PLA raw material to enter into a screw extruder for fused compression, enabling the fused and compressed PLA raw material to enter into a spanning component, spraying out tows throughthe spanning device, cooling the tows through a cross air blasting device, an oiling device and a paved path, then drafting the tows through a drafting device, after entering into a main interlacer added interlacing point, enabling the drafted tows into enter into a coil for coiling. The production method provided by the invention is beneficial to effective promotion of the PLA moisture wicking silk-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 perspiration imitation silk 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, the production method of perspiration imitation silk fiber is mainly prepared by fiber-forming polymer. However, the sweat-wicking imitation silk fiber made of this material is difficult to degrade in the soil, and once it is discarded randomly, it is easy to cause environmental pollution. Therefore, the use of polylactic acid to manufacture sweat-wicking imitation silk fiber is on the agenda....
