Abstract

A bamboo charcoal polylactic acid particle spinning system comprises a stirring tank, a granulating screw extruder, a first stock bin, a second stock bin, a spinning screw extruder and a spinning box. A discharge port of the stirring tank is connected with a feed port of the granulating screw extruder, a discharge port of the granulating screw extruder is connected with a feed port of the first stock bin, a discharge port of the second stock bin is connected with a feed port of the spinning screw extruder through a main discharge pipe, a discharge port of the first stock bin is connected with the main discharge pipe through a material mixing pipe, the material mixing pipe is provided with a micro meter, a discharge port of the spinning screw extruder is connected with the spinning box through a melt pipeline, and the melt pipeline is sequentially provided with a filtering and impurity removing device and a dynamic-static-integrated pipeline type material mixing device in the flowing direction of melt. According to the bamboo charcoal polylactic acid particle spinning system, polylactic acid is modified by adopting nano-scale bamboo fragrance carbon micro powder, and therefore prepared fibers have the advantages that the initial modulus is decreased, the moisture regain is increased, the wear resistance is improved, and the air permeability and the handfeel are significantly improved.

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 system. 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 a...
