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 1~8

[0063] A kind of modified acrylic fiber, concrete steps comprise:

[0064] (1) prepare the first graphene dispersion, the particle diameter of graphene in the first graphene dispersion is less than 1 μm; prepare the second graphene dispersion, the particle diameter of graphene in the second graphene dispersion Between 1 and 2 μm;

[0065] (2) the fiber is immersed in the first graphene dispersion at the first temperature, then take out the acrylic fiber impregnated with the first graphene, and continue to immerse it in the second graphene dispersion for 30min, then take it out, dry, Acrylic modified fiber is obtained.

[0066] 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.

[0067] Table 1 shows the process conditions of Examples 1-8 and the test results of the obtained modified fibers.

[0068] Table 1...

Embodiment 9~12

[0072] A modified fiber, the difference from Example 3 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% (Example 9), 0.5wt% (Example 10), 1wt% (Example 11), 2wt% (Example 12).

[0073] Using the same performance test method as in Example 3, the test results are shown in Table 2.

Embodiment 13

[0075] 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 acrylic fibre product. Graphene flakes exist in and out of acrylic fibres of the modified acrylic fibre product; the acrylic fibre product comprises acrylic fibres, acrylic yarns or acrylic fabric. According to the modified acrylic fibre product, graphene is adhered to or added into the interiors and the exteriors of the acrylic fibres simultaneously, so that the uniformity and the firmness of the existence of the graphene are improved; the electrical conductivity of the acrylic fibres is improved by adding the graphene or / and biomass graphene; the far infrared performance of the acrylic fibres is further enhanced by adding oxidized graphene and / or the biomass graphene; according to the preparation method provided by the invention, the graphene can be effectively filled into the interiors of the acrylic fibres, meanwhile, the exteriors of the acrylic fibres are coated with the graphene flakes, and uniform distribution of the graphene on the acrylic fibres is realized by soaking the acrylic fibre product with a graphene solution.

Description

technical field [0001] The invention belongs to the field of fiber product preparation, specifically relates to a modified acrylic fiber product, a preparation method and its application, in particular to a conductive modified acrylic 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 th...
