Embodiment 1

[0020] Example 1: Mix carbon nanotubes with a diameter of less than 60nm and ethanol to form a solution of 5 grams of carbon nanomaterials per liter, and use an ultrasonic oscillator to fully disperse it, then immerse medical mesh gauze in the solution for several minutes, and take out Dry; or apply the solution evenly on the medical mesh gauze with a brush, and dry to obtain the desired cotton fabric.

Embodiment 2

[0021] Embodiment 2: Mix the mixture of carbon nanotubes and carbon nanofibers with distilled water to form a solution of 20 grams of carbon nanomaterials / liter, and stir to make it fully dispersed, then soak the cotton cloth in the solution for several minutes, take it out and dry it; or use Apply the solution evenly on the cotton cloth with a brush, and dry to obtain the desired cotton fabric.

Embodiment 3

[0022] Example 3: Mix carbon nanofibers with a diameter below 300nm and acetone to form a solution of 15 grams of carbon nanomaterials per liter, and use an ultrasonic oscillator to fully disperse it, then immerse the mesh gauze in the solution for several minutes, take it out and dry it ; Or apply the solution evenly on the mesh gauze with a brush, and dry to obtain the desired cotton fabric.

Abstract

The making process includes mixing nano carbon material and volatile solvent to compound solution with dispersed nano carbon material of 3-50 g in each liter, soaking cotton gauze in the solution or brushing the solution to the cotton gauze, and drying to obtain the cotton fabric. The cotton fabric has virus and bacteria killing function greatly higher than that of other active carbon material.The present invention adopts fibrous carbon nano material, which is twisted to cotton fabric and has great adhesion, high durability and other advantages compared with granular carbon nano material and other kind of carbon nano material.

Description

technical field [0001] The invention relates to a cotton fabric for isolating and killing viruses and / or bacteria, especially suitable for isolating and killing severe viruses and bacteria. Background technique [0002] At present, ordinary medical masks generally only play the role of isolating dust, bacteria and viruses, but do not kill bacteria or viruses, and their filtering effect is poor. According to different requirements, it is generally made into several layers or more than ten layers. However, as the thickness increases, its wearing comfort decreases, which is not conducive to long-term wearing. At present, masks made of activated carbon materials have appeared on the market. Its main function is to use the strong adsorption of activated carbon to achieve the effect of killing bacteria and viruses. The price is about twice that of ordinary masks, and it is hard and comfortable to wear. Sex is poor. [0003] For severe viruses or bacteria (such as SARS virus), me...
