Embodiment 1

[0021] The polyacrylonitrile resin with a molecular weight of 70,000 was dried for later use, and 0.5g of conductive polyaniline, 0.5g of nano-silver, 0.1g of polyethylene glycol with a molecular weight of 4,000, 0.5g of glycerin, and 0.5g of polyethylene oxide with a molecular weight of 1,000,000 were dissolved in 300gN , N-dimethylformamide, then add 100g polyacrylonitrile dry powder, heat and stir at 60°C for 1 hour to make spinning solution, then pour the spinning solution into special spinning equipment to start melt blown spinning to The non-woven fabric was prepared on the web curtain, and the hot air temperature during spinning was 150°C. The prepared acrylic non-woven fabric was washed in a 70°C water bath for 30 minutes. After the washing was completed, it was placed in a 90°C Dry it in an oven to constant weight to finally obtain an antistatic and antibacterial acrylic nonwoven fabric.

Embodiment 2

[0023] The polyacrylonitrile resin with a molecular weight of 100,000 was dried for later use, and 0.9g of conductive polyaniline, 0.7g of nano-silver, 0.3g of polyethylene glycol with a molecular weight of 3000, 0.8g of glycerin, and 0.8g of polyethylene oxide with a molecular weight of 2,000,000 were dissolved in 300gN , N-dimethylformamide, then add 100g polyacrylonitrile dry powder, heat and stir at 80°C for 1 hour to make spinning solution, then pour the spinning solution into special spinning equipment to start melt blown spinning to The non-woven fabric is prepared on the web curtain, and the hot air temperature during spinning is 170°C. The prepared acrylic non-woven fabric is washed in an 80°C water bath for 30 minutes. After the washing is completed, it is placed in a 100°C Dry it in an oven to constant weight to finally obtain an antistatic and antibacterial acrylic nonwoven fabric.

Embodiment 3

[0025] The polyacrylonitrile resin with a molecular weight of 90,000 was dried for later use, and 1.5g of conductive polyaniline, 1.1g of nano-silver, 0.3g of polyethylene glycol with a molecular weight of 4,000, 0.8g of glycerin, and 0.8g of polyethylene oxide with a molecular weight of 3,000,000 were dissolved in 250gN , N-dimethylformamide, then add 100g polyacrylonitrile dry powder, heat and stir at 90°C for 1 hour to make spinning solution, then pour the spinning solution into special spinning equipment to start melt blown spinning to The non-woven fabric was prepared on the web curtain, and the hot air temperature during spinning was 170°C. The prepared acrylic non-woven fabric was washed in a 90°C water bath for 30 minutes. After the washing was completed, it was placed in a 110°C Dry it in an oven to constant weight to finally obtain an antistatic and antibacterial acrylic nonwoven fabric.

Abstract

The invention relates to an acrylic nonwoven fabric, in particular to an antistatic and antibacterial acrylic nonwoven fabric and a preparation method thereof. The antistatic and antibacterial acrylicnonwoven fabric is prepared from polyacrylonitrile dry power dry basis, antistat, antibacterial agent, pore-foaming agent, synergist, anti-sticking agent and solvent; the synergist is glycerinum, andthe pore-foaming agent is polyethylene glycol; the anti-sticking agent is polyoxyethylene; and the weight-average molecular weight of the polyacrylonitrile dry power is 70000-100000. The antistatic and antibacterial acrylic nonwoven fabric has the advantages that the pore-foaming agent and the synergist are introduced, the problems that the compatibility is poor when the antistat and the antibacterial agent are added into the polyacrylonitrile simultaneously, the antistatic and antibacterial performance is poor, and the effect of simultaneous addition of the antistat and antibacterial agent descends than that of single addition of the antistat and antibacterial agent are solved, the prepared nonwoven fabric has a significant antistatic and antibacterial effect, the effect of the simultaneous addition of the antistat and antibacterial agent is greatly improved than that of the single addition of the antistat and antibacterial agent, and the physical and mechanical properties of the nonwoven fabric cannot not be affected. The invention further provides the preparation method, the materials are obtained easily, the industrialized production is easy, and the economic and social benefits are better.

Description

technical field [0001] The invention relates to an acrylic fiber nonwoven fabric, in particular to an antistatic and antibacterial acrylic fiber nonwoven fabric and a preparation method thereof. Background technique [0002] There are many ways to prepare non-woven fabrics, among which melt-blown non-woven fabrics are a kind of polymer direct-forming technology. That is to say, the superfine fiber is evenly sprayed on the web curtain by hot air, and becomes a melt-blown non-woven fabric by its own bonding or other reinforcement methods. Because the fibers of the non-woven fabric are very thin, the formed fiber web has a large specific surface area, small voids, large void ratio, and fluffy structure, so it has good filterability, shielding, heat insulation and hygroscopicity. . The dry-laid acrylic non-woven fabric has a unique dog-bone structure, which makes its characteristics close to natural wool. The fabric has good elasticity and light weight. The finished product ha...
