Abstract

The invention discloses a preparation method of a polylactic acid fiber for outdoor products. The method comprises the steps of stirring polylactic resin, polyether ketone, a rapeseed dreg compound, talcum powder, inorganic hollow spheres, microcrystalline wax and cardanol polyoxyethylene ether to obtain a mixed material; heating the mixed material, adding diphenyl tolyl phosphate, dibutyltin maleate, color master batches, disproportionated rosin and an antioxidant and stirring evenly; and feeding the mixture into a twin-screw extruder for extruding, cooling to a room temperature, and then carrying out melt spinning to obtain the polylactic acid fiber for the outdoor products. The method is simple and low in cost; the obtained polylactic acid fiber is excellent in strength, toughness and heat resistance, is green, environment-friendly and degradable and is suitable for the field of textile fabrics.

Description

technical field [0001] The invention relates to the technical field, in particular to a method for preparing polylactic acid fibers used in outdoor products. Background technique [0002] As we all know, ordinary synthetic fibers are difficult to decompose in the natural environment for hundreds of years, and plastic waste is recognized as an artificially produced substance that pollutes the environment. However, as an important textile fiber, synthetic fiber has surpassed natural fiber and is widely used in various industries. Studies have found that the textiles produced by polylactic acid fibers can be completely degraded into carbon dioxide and water in a composting environment, and polylactic acid fibers have good compatibility, transparency, solvent resistance and biaxial stretching properties, etc., can be used A variety of processing methods, but due to its poor toughness and low heat resistance, it has not been widely used. Contents of the invention [0003] Bas...
