Abstract

The invention discloses a preparation method of a hemp carbon polyester fiber with high-efficient adsorption and hygroscopic properties. The preparation method comprises the following steps: (1) feeding nanoscale hemp carbon powder, a silane coupling agent and nanoscale silica powder to water, stirring at room temperature, adhering the nanoscale silica powder to holes in the surface of the nanoscale hemp carbon powder, filtering and drying to obtain composite powder; (2) extruding and granulating the obtained composite powder and polyester slices to obtain functional master batches; (3) melting and spinning the obtained functional master batches and the polyester slices to obtain the polyester fiber containing the composite powder; and (4) carrying out alkali washing, removing the nanoscale silica powder adhered to hemp carbon, and forming a hole structure in the polyester fiber, which extends to the surface of the polyester fiber, washing and drying to obtain the hemp carbon / polyester fiber with the hole structure. The hemp carbon / polyester fiber prepared by the invention has high-efficient adsorption and hygroscopic properties, and can be widely applied to the fields such as clothes and home textiles.

Description

technical field [0001] The invention belongs to the technical field of functional fiber production, and relates to a preparation method of hemp charcoal / polyester fiber with high-efficiency adsorption and moisture absorption properties. Background technique [0002] Polyester and polyester fiber have flourished since the 1970s and have been widely used in clothing and industrial fields. Polyester fiber has good comprehensive properties, and its strength, wear resistance, resilience and dimensional stability can better meet the needs of various purposes. But polyester fiber is a typical hydrophobic fiber, its moisture regain is only about 0.4%, and polyester fiber generally has a smooth surface and no hole structure. It is poor in wearing comfort when used as a wearing material, and it is easy to produce stuffy feeling when wearing it in a humid and hot state. Affect mood. At the same time, in the field of textile and clothing, it is no longer satisfied with traditional non...
