Abstract

The invention discloses a graphene tencel composite fiber and a preparation method thereof. The graphene tencel composite fiber is prepared by mixing a graphene oxide solution and cellulose pulp into NMMO (N-methylmorpholine-N oxide) and water, dissolving, filtering, spinning by virtue of a dry-wet spinning process and then finishing by virtue of silk yarns and a graphene oxide finishing solution. The tencel composite fiber contains graphene and is prepared by the following steps: preparing a spinning solution, spinning, and finishing the yarns by virtue of graphene. The obtained yarns can sufficient integrate the excellent characteristics of tencel and graphene, has excellent physical properties of the tencel, such as moisture absorption performance, dyeing performance, comfort, high strength and the like, also improves the flexibility, conductivity, and bacteria resistance of the grpahene, and are ideal fibers for clothes. The preparation process and a production process are pollution-free to the environment, the fiber product waste can be naturally degraded, damage to the environment can be avoided, and a recyclable resource is easy to form.

Description

technical field [0001] The invention belongs to the field of new textile materials, and relates to a graphene tencel composite fiber and a preparation method thereof. Background technique [0002] Graphene is a new type of carbon nano light material with a unique two-dimensional crystal structure of single atomic layer. Due to its ultra-high strength, excellent electrical conductivity, thermal conductivity, and light transmittance, as well as excellent antibacterial, anti-ultraviolet, and far-infrared functions. [0003] Tencel fiber uses wood pulp as raw material to produce a new fiber through solvent spinning method. It has the comfort of cotton, the strength of polyester, the luxurious beauty of wool and the unique feel and soft drape of silk, all of which are extremely resilient when dry. In the wet state, the wet strength is far better than the cellulose fibers of cotton. Pure natural materials, environmentally friendly manufacturing process, green and environmentall...
