Abstract

A bamboo charcoal polylactic acid particle spinning technology comprises the steps that bamboo charcoal micro powder and polylactic acid particles are mixed and then sent to a granulation screw extruder to be produced into a bamboo charcoal polylactic acid master batch; the bamboo charcoal polylactic acid master batch is dried; the bamboo charcoal polylactic acid master batch is subjected to quantitative metering of a micro-meter and then sent into a spinning screw extruder together with polylactic acid dry chips to be processed into a bamboo charcoal polylactic acid melt; the bamboo charcoal polylactic acid melt is filtered through a melt filter; the filtered bamboo charcoal polylactic acid melt is sent into a spinning manifold through a melt pipeline; the bamboo charcoal polylactic acid melt is spun into bamboo charcoal polylactic acid fiber through a spinning component in the spinning manifold. According to the spinning technology, polylactic acid is modified through nanoscale bamboo charcoal micro powder, so that the prepared fiber has lower initial modulus, higher moisture regain, higher wear resistance, higher air permeability and better hand feeling.

Description

technical field

[0001] The invention belongs to the technical field of polylactic acid fiber production, and in particular relates to a bamboo charcoal polylactic acid particle spinning process. Background technique

[0002] Polylactic acid (PLA) fiber is made from corn, wheat, potato, sugar beet and other starchy agricultural products, which are fermented to produce lactic acid and then polycondensed and melt-spun. The raw materials of PLA fiber come from a wide range of sources. It can be decomposed into carbon dioxide and water by microorganisms in soil or seawater. When burned, it will not emit poisonous gas and cause pollution. It is a sustainable ecological fiber. The fabric has good hand feeling and drapability, anti-ultraviolet radiation, low flammability and excellent processing performance. It is suitable for various fashion, casual wear, sporting goods and sanitary products, etc., and has broad application prospects.

[0003] Polylactic acid (PLA) fiber has many ...
