Problems solved by technology

However, this fabric functional finishing method has a long processing process and low production efficiency, and large-scale industrial production is limited.
CN104262953B has reported a kind of graphene-coated glass fiber reinforced resin-based composite material and preparation method, this utilizes electrostatic adsorption to attach graphene to the method bonding fastness of glass fiber surface is not strong, easily peels off in subsequent process
However, it is still rare to see reports on the graphene modification of fibers, especially industrial fibers, in the process of melt spinning.

Abstract

The invention relates to a production method of industrial fibers coated with doped graphene oxide on line. The production method comprises the following steps: (1) carrying out mechanical stirring and ultrasonic dispersion on the doped graphene oxide, a dispersant and a spinning oil agent according to the mass ratio of 5-40:0.2-1:94.8-59 at room temperature greater than or equal to 25 DEG C to obtain a mixed coating solution; (2) adding the mixed coating solution at a spinning oil agent oiling position before industrial fiber spun filaments enter a drafting roller; and (3) carrying out multi-stage drafting and high-temperature shaping on the spun filaments coated with the doped graphene oxide, which are obtained on line in step (2), to prepare the industrial fibers with multiple compoundfunctions. According to the production method provided by the invention, the mixed coating solution containing the doped graphene oxide is used for carrying out on-line coating in a production processof the industrial fibers, so that the fibers have excellent anti-static, antibacterial, anti-ultraviolet aging and flame-retarding properties and the like; and the production method is especially suitable for further processing industrial composite textile materials including subsequent glue dipping, fitting and the like.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for producing multiple composite functional fibers. Background technique [0002] Technical fibers are the basic raw materials of industrial textiles. Technical textiles usually refer to specially designed textiles with engineering structure characteristics, specific application fields and specific functions, which are different from general clothing textiles and home textiles. Therefore, multi-functionalization of the properties of industrial fibers is also required. [0003] Functional textiles are generally realized by adding functional auxiliaries. To achieve multiple composite functions, multiple functional auxiliaries need to be added at the same time, so the processing cost is high, and the processing difficulty is also increased. Therefore, it is necessary to find a functional additive with multiple complex functional properties at the same time. ...
