Abstract
The invention relates to a graphene polylactic acid bicomponent composite fiber and a preparation method and equipment thereof, and belongs to the technical field of melt-spinning fibers. The preparation method comprises the following steps: respectively drying and mixing 60-75wt% of polylactic acid slices and 25-40wt% of graphene master batches to obtain a component A; drying the polylactic acidslices as a component B; respectively melting and extruding the component A and the component B, and then spinning together. The bicomponent composite fiber prepared by the graphene polylactic acid bicomponent composite fiber and preparation method and equipment thereof has obvious crimping effect, excellent elasticity and fluffiness, and good effects of strength, wear resistance, heat preservation, bacteriostasis and conduction.
Description
technical field [0001] The invention relates to the technical field of melt spinning fibers, more specifically, it relates to graphene polylactic acid bicomponent composite fibers and a preparation method and equipment thereof. Background technique [0002] Polylactic acid fiber is made from starch-containing agricultural products such as corn, wheat, and sugar beet. After fermentation to generate lactic acid, it is made by polycondensation and melt spinning. Polylactic acid fiber is a synthetic fiber that can be planted, easy to plant, and degradable waste. It can be decomposed into carbon dioxide and water under the action of microorganisms, and will not cause environmental pollution. It is a sustainable ecological fiber with good Excellent water diffusibility, environmental protection and safety. However, there are few long-chain branches in the molecular chain of polylactic acid, and the polylactic acid fiber has the defects of poor toughness and elasticity, low strengt...
