Technical Field
The invention relates to a preparation method of mineral graphene down-like cotton, and belongs to the technical field of chemical fibers.
Background
The down-like cotton is made of synthetic fiber produced by chemical fiber special process with different specifications, and is called down-like cotton because the quality of the synthetic fiber is similar to that of down and cotton. It features light weight, softness, tensile strength and water washing. The disadvantages are static electricity, non-degradable material, pollution, environmental pollution and easy allergy.
Disclosure of Invention
The invention aims to solve the problems and provide a preparation method of mineral graphene down-like cotton, and the preferable technical scheme in the technical schemes provided by the invention comprises the following steps: the conductive performance of the down-like cotton (synthetic fiber) can be improved by adding the graphene material in the down-like cotton (synthetic fiber), and the technical effect of eliminating static electricity generated during use of the down-like cotton (synthetic fiber) is described in detail below.
In order to achieve the purpose, the invention provides the following technical scheme: a preparation method of mineral substance graphene down-like cotton comprises the following steps:
(1) fully mixing 60% of polyester fiber, 20% of hollow fiber and 20% of low-melting-point fiber in percentage by weight, mixing with a graphene solution, and carrying out melt spinning to obtain mixed fiber;
(2) sending the mixed fiber into a vibration cotton feeding box, carding the mixed fiber into a mesh sheet by a carding machine, cross-lapping the mesh sheet by a reciprocating forming machine, and lapping the mesh sheet into the net-forming down-like cotton with required thickness and weight;
(3) and (3) feeding the net-formed down-like cotton into a drying room, gradually heating to melt the low-melting-point fibers, connecting the net sheets with each other, and cooling by a cooling roller to obtain the down-like cotton.
The preparation method of the graphene solution comprises the following steps: placing natural graphite and NaN03 into a reaction bottle, carrying out ice bath, adding 98% concentrated sulfuric acid by mass, adding KMn04, keeping the temperature for 20min when the temperature of the mixed solution is 160-180 ℃, sequentially adding hydrogen peroxide and hydrochloric acid, and preparing the solution to be neutral by a titration method to obtain the graphene solution.
Preferably, the mass percent of the graphene solution in the mixed fiber is 10%, and the mass percent of the mixture of the polyester fiber, the hollow fiber and the low-melting-point fiber is 90%.
Preferably, the polyester fiber, the hollow fiber and the low-melting fiber have a fiber length of 30D to 200D and a cut length of 38mm to 64 mm.
The invention has the beneficial effects that: the graphene is added in the preparation process of the down-like cotton, so that the prepared down-like cotton is limited to have electric conductivity, static electricity generated in the processing and using processes of the down-like cotton is prevented, the down-like cotton can be used as far infrared fabric only by the graphene, and the heat insulation performance of the down-like cotton is improved. Meanwhile, the down-like cotton prepared by the method is produced by fibers of different varieties and different specifications according to a certain proportion. Because the fiber length and thickness are different and the proportion is reasonable, more air is retained between the fibers, and a good heat insulation medium is generated, thereby forming a good heat insulation structure; as most of the used materials are functional differential fiber waste materials, certain properties of the fiber waste materials are re-volatilized in the using process, the application range of the regenerated fiber is expanded, and the environment protection and resource saving are facilitated.
