Problems solved by technology

Although the conductive fiber has been greatly developed, there are still some problems, such as the fabric made of metal conductive fiber and metal-plated conductive fiber feels rough, poor comfort, conductive polymer process is more complicated, and the pollution is serious
Furthermore, the composite firmness of graphene fiber products prepared by coating or simple impregnation process is not strong enough, and the additional function will be lost after washing many times.

Embodiment 1～9

[0071] A modified fiber, the specific steps comprising:

[0072] (1) prepare the first graphene dispersion liquid, the particle size of graphene in the first graphene dispersion liquid is between 0.1~1 μm; prepare the second graphene dispersion liquid, graphite in the second graphene dispersion liquid The particle size of alkene is between 1 and 2 μm;

[0073] (2) Soak the fiber in the first graphene dispersion at the first temperature, then take out the fiber impregnated with the first graphene, and continue to immerse it in the second graphene dispersion for 30min, then take it out and dry to obtain modified fiber.

[0074] Performance test: The obtained modified fiber is tested according to GB / T 14342-2015; after that, the modified fiber is washed 50 times, and the washed modified fiber is continued according to GB / T 14342-2015 detection.

[0075] Table 1 shows the process conditions of Examples 1-9 and the test results of the obtained modified fibers.

[0076] Table 1:...

Embodiment 10～13

[0079] A modified fiber, the difference from Example 7 is that nanocellulose (aspect ratio 80~120, diameter below 10nm) is dispersed simultaneously in the first graphene dispersion described in step (2), and the nanocellulose The concentration in the dispersion liquid is 0.1wt%, 0.5wt%, 1wt%, 2wt%.

[0080] Using the same performance test method as in Example 7, the test results are shown in Table 2.

Embodiment 14

[0082] A modified fiber, the difference from Example 3 is that the first and second graphene dispersions are replaced by graphene oxide dispersions, and the reduction step is carried out, specifically: in step 2) take out the impregnation for the second time The impregnated fiber is put into the hydrazine hydrate reducing solution for reduction treatment, and then dried to obtain the modified fiber. Using the same performance test method as in Example 3, the test results are shown in Table 2.

Abstract

The invention relates to a modified fiber product. The modified fiber product contains modified fiber, wherein graphene substances are contained inside the modified fiber, and graphene substances are also contained outside the modified fiber. A method comprises the following steps: immersing the non-modified fiber product into a graphene substance dispersing solution, and then cooling and drying to obtain the modified fiber product, wherein the range of the immersing temperature is at high-elastic-state temperature of a fiber material in the non-modified fiber product. Graphene are adhered or filled inside and outside the fiber, so that the evenness of the graphene can be increased, and the conductivity of the fiber can be improved; and by using the preparation method, the graphene can be effectively filled inside the fiber, and the fiber is externally cladded with graphene substances, so that the even distribution of graphene in the fiber can be realized.

Description

technical field [0001] The invention belongs to the field of fiber product preparation, specifically relates to a modified fiber product, a preparation method and its application, in particular to a conductive modified fiber product, a preparation method and its application. Background technique [0002] The development of conductive fibers began in the 1960s. Conductive fibers usually refer to those with a specific resistance lower than 10 in a standard environment (temperature 20°C, humidity 65%). 7 Ω·cm. Its development process roughly includes four stages: metal fiber, carbon fiber and composite conductive fiber containing carbon black composite polymer, conductive fiber containing metal salt, conductive polymer conductive fiber. Although conductive fibers have been greatly developed, there are still certain problems, such as fabrics made of metal conductive fibers and metal-plated conductive fibers, which have rough hand feeling and poor comfort, and the conductive pol...
