Description
Technical Field
The invention belongs to the technical field of spinning, and particularly relates to a production method of a multi-composite functional fiber.
Background
The industrial fiber is a basic raw material of industrial textiles, and the industrial textiles are generally textiles which are specially designed and have engineering structure characteristics, specific application fields and specific functions, and are different from common clothing textiles and household textiles. Therefore, there is a demand for the multifunctionalization of the performance of industrial fibers.
Functional textiles are generally realized by adding functional additives, and multiple functional additives are needed to be added simultaneously to achieve multiple composite functions, so that the processing cost is high, and the processing difficulty is increased. Therefore, it is necessary to find a functional additive having multiple functional properties.
Graphene is a new single-layer sheet-structured nano material composed of carbon atoms, and due to the unique structure, the graphene has multiple composite functions of good antibiosis, antistatic property, ultraviolet resistance, flame retardance, heat resistance and the like. CN102168370B uses a fabric as a filter cloth, and makes the water solution of graphene oxide permeate the filter cloth in a filtering way, thereby obtaining a fabric containing a cross-linking agent and graphene oxide, and then uses radiation cross-linking or thermal cross-linking to initiate cross-linking polymerization reaction to obtain an antibacterial fabric; CN103469555B reports that a fabric with ultraviolet-proof and antistatic functions is prepared by padding and fixing a mixed solution of graphene and water-soluble polyurethane on a fabric at a high temperature. However, the functional finishing method of the fabric has long processing flow, low production efficiency and limited large-scale industrial production. CN104262953B reports a graphene-coated glass fiber reinforced resin matrix composite and a preparation method thereof, and the method of attaching graphene to the surface of glass fiber by using electrostatic adsorption has weak bonding fastness and is easy to peel off in the subsequent process. CN108193298A reports that in the regenerated cellulose wet solution spinning process, graphene oxide synchronously coated on the same base obtains excellent functions of antistatic property, sterilization, ultraviolet resistance and the like. However, there is a report on graphene modification of fibers, particularly industrial fibers, on line during melt spinning.
