Abstract

The invention discloses blended yarn with hemp and cotton multifunctional fiber reinforced by graphene fiber. The blended yarn is prepared from the following steps that 1, hemp fiber is placed in a pectinase solution to be soaked at normal temperature, continues to be soaked in a chitosan aqueous solution, and then is dehydrated and dried; 2, the hemp fiber, bamboo fiber, wool fiber and cotton fiber are placed in acetone to be soaked while ultrasonically oscillated and are washed, dehydrated and dried to prepare the hemp and cotton multifunctional fiber; 3, the hemp and cotton multifunctional fiber and graphene fiber are mixed uniformly and entwisted into the blended yarn. As the graphene fiber is added for blending, strength and tenacity of the hemp and cotton multifunctional fiber blended yarn are improved, and the specific resistance of the blended yarn is about 10-103 omega*m; after mild biological enzyme treatment, the hemp fiber has the degumming effect and avoid retting degumming caused by chemicals, natural phenolic substances and derivatives thereof contained in the hemp fiber are well reserved, and the effective and natural antibacterial function is achieved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a graphene fiber-reinforced blended yarn of hemp-cotton multifunctional fiber. Background technique [0002] Conductive fibers have always been a research hotspot for functional fibers, generally referring to resistivity less than 10 8 The fiber of Ω·cm has the functions of conduction, electric heating and anti-electromagnetic radiation, and is usually concentrated in the fields of anti-static clothing or anti-electromagnetic radiation clothing used in special occasions. [0003] The main methods for the manufacture of conductive fibers include: one is to coat the surface of conventional fibers with conductive components, and the other is to mix conductive materials with fiber raw materials and make conductive fibers by spinning. The method of coating the conductive layer on the surface of the fiber is to coat the conductive material containing metal, carbon black o...
