Embodiment 1～7

[0063] A modified nylon fiber, the specific steps include:

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

[0065] (2) Immerse the nylon fiber in the first graphene dispersion at the first temperature, then take out the nylon fiber impregnated with the first graphene, and continue to immerse it in the second graphene dispersion for 30 minutes, then take out and dry , to obtain modified nylon fibers.

[0066] Performance test: The obtained modified nylon fiber is tested according to GB / T 14342-2015; then the modified nylon fiber is washed 50 times, and the modification after washing is continued according to GB / T 14342-2015. Nylon fibers were tested.

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

Embodiment 9～12

[0072] A modified fiber, the difference from Example 3 is that nanocellulose (aspect ratio 80-120, diameter less than 10nm) is dispersed in the first graphene dispersion in step (2) at the same time, the nanocellulose is The concentration in the dispersion liquid was 0.1 wt % (Example 9), 0.5 wt % (Example 10), 1 wt % (Example 11), 2 wt % (Example 12).

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

Embodiment 13

[0075] A modified nylon fiber, the difference from Example 3 is that both the first and second graphene dispersions are replaced by graphene oxide dispersions, and a reduction step is performed, specifically: in step 2) taking out and immersing the second The nylon fibers that have been impregnated for the second time are put into a hydrazine hydrate reducing solution for reduction treatment, and then dried to obtain modified nylon fibers. Adopt the same performance testing method as Example 3, and the test results are shown in Table 2.

Abstract

The invention relates to a modified polyamide fiber product. Graphene sheet layers are arranged inside and outside polyamide fiber of the modified polyamide fiber product, and the polyamide fiber product comprises polyamide fiber, polyamide yarn and polyamide fabric. Graphene is attached or filled both inside and outside the polyamide fiber, so that uniformity and firmness of the graphene are improved; by adding graphene and/or biomass graphene, conductive performance of the polyamide fiber is improved; by adding oxidized graphene and/or biomass graphene, far infrared performance of the polyamide fiber is further improved. By the preparation method, the graphene can be effectively filled into the inside of the polyamide fiber, the outside of the polyamide fiber is coated with the graphene sheet layer, and uniform distribution the graphene on the polyamide fiber is realized by soaking the polyamide fiber product in a graphene solution.

Description

technical field [0001] The invention belongs to the field of fiber product preparation, in particular to a modified nylon fiber product, a preparation method and use thereof, and in particular to a conductive modified nylon fiber product, a preparation method and use thereof. Background technique [0002] The development of conductive fibers began in the 1960s. Conductive fibers usually refer to a specific resistance below 10 under a standard environment (temperature 20°C, humidity 65%). 7 Ω·cm. Its development process roughly includes four stages: metal fibers, carbon fibers and composite conductive fibers containing carbon black composite polymers, conductive fibers containing metal salts, and conductive polymer conductive fibers. Although conductive fibers have been developed by leaps and bounds, there are still some problems, such as fabrics made of metal conductive fibers and metal-plated conductive fibers have a rough hand, poor comfort, complex conductive polymer pro...
