Embodiment 1

[0050] A preparation method of antistatic agent, comprising the following steps:

[0051] Disperse 2g of graphene oxide in 1L of deionized water, and ultrasonically disperse it for 1h under the condition of ultrasonic frequency of 40kHz and power of 450W to obtain graphene oxide hydrosol; add 0.5g modifier to the graphene oxide hydrosol, Stir for 20 minutes; filter, wash with water, and vacuum-dry at 50°C for 10 hours to obtain modified graphene oxide.

[0052] The modifying agent is octadecyl dimethyl benzyl ammonium chloride.

[0053] An antistatic fiber comprises 5wt% of the antistatic agent and 95wt% fiber matrix.

[0054] The preparation method of described antistatic fiber, comprises the following steps:

[0055] 1. Pretreatment: vacuum-dry the antistatic agent and the fiber matrix at 100°C for 8 hours;

[0056] Ⅱ. Dry mixing: Put the pretreated antistatic agent and fiber matrix into a high-speed mixer with a rotation speed of 900 rpm and a mixing time of 5 minutes to...

Embodiment 2

[0068] Basically the same as Example 1, the only difference is:

[0069] Described modifying agent is glyceryl monostearate.

Embodiment 3

[0071] Basically the same as Example 1, the only difference is:

[0072] The modifier is formed by mixing glyceryl monostearate and octadecyldimethylbenzyl ammonium chloride in a weight ratio of 1:1.

Abstract

The invention discloses an antistatic fabric and a preparation method thereof. The antistatic fabric comprises the following raw materials by weight: 30wt%-80wt% antistatic fiber, 20wt%-70wt% cotton fiber; the antistatic fiber is composed of 5wt%-40wt% antistatic agent and 60wt%-95wt% fiber The base is prepared. The antistatic fabric prepared by the invention has both excellent functional effects of antistatic and antibacterial. In terms of antistatic, the charge surface density can reach 0.42uc / m 2 Compared with other methods, the product has a gain of about 70%. At the same time, in terms of antibacterial performance, the bactericidal rate of Escherichia coli can reach 98.6%. Compared with other methods, the fabric has a significant gain, resulting in an unexpected technology. Effect.

Description

technical field [0001] The invention relates to an antistatic fabric and a preparation method thereof. Background technique [0002] Textile materials are electrical insulator materials, especially synthetic fibers such as polyester, acrylic fiber, and polyvinyl chloride, which have poor hygroscopic performance and usually have high specific resistance. Therefore, in the process of textile processing, the close contact and friction between fibers or fibers and machine parts, as well as the mutual contact and friction of processed textiles, will cause the transfer of charges and the generation of static electricity. [0003] The existence of static electricity will affect the quality of the product and the wearing performance of the fabric at the slightest, and the discharge will generate sparks, which will cause fire and cause serious consequences. In some special environments and workplaces, such as electronics industry, medical and health industry, gas stations, mines and...
