Embodiment 1

[0055] Cut the polypropylene non-woven fabric into a shape of 1cm×1cm, soak it in 3mol / L hydrochloric acid solution for 24 hours, take it out, wash it with deionized water several times until there is no hydrochloric acid residue, and dry it naturally in a ventilated place to remove the fabric sample. Impurities, oil stains and residual additives on the surface are stored in a desiccator for later use.

[0056] Dissolve aloe-emodin in absolute ethanol to prepare a 0.01 mg / mL emodin ethanol solution, and store it at 4°C for later use.

[0057] Place the spare polypropylene nonwoven fabric in a 5mL small bottle with a lid, add 1mL of 20% glutaraldehyde solution, shake in a water bath at 90°C at 150rpm for 120min, take it out and wash it with deionized water to dry. Then place it in 1mL polyethyleneimine solution with a volume fraction of 5%, shake in a 40°C water bath at 150rpm for 20min, remove the residual polyethyleneimine solution on the surface with deionized water, and dry...

Embodiment 2

[0061] Cut the polypropylene non-woven fabric into a shape of 1cm×1cm, place it in a 6mol / L hydrochloric acid solution and soak it for 24 hours, take it out, wash it with deionized water several times until there is no hydrochloric acid residue, and dry it to remove impurities, oil and dirt on the surface of the fabric sample. Residual additives are stored in a desiccator for later use.

[0062] Dissolve aloe-emodin in absolute ethanol to prepare a 0.002 mg / mL emodin ethanol solution, and store it at 4°C for later use.

[0063] Place the spare polypropylene nonwoven fabric in a 5mL small bottle with a lid, add 1mL glutaraldehyde solution with a volume fraction of 15%, shake it in a water bath at 70°C at 150rpm for 100min, take it out and wash it with deionized water to dry. Then place it in 1mL polyethyleneimine solution with a volume fraction of 6%, shake in a water bath at 30°C at 150rpm for 30min, remove the residual polyethyleneimine solution on the surface with deionized ...

Embodiment 3

[0065] Cut the polypropylene non-woven fabric into a shape of 1cm×1cm, soak it in 9mol / L hydrochloric acid solution for 24 hours, take it out, wash it with deionized water several times until there is no hydrochloric acid residue, and dry it to remove impurities, oil and dirt on the surface of the fabric sample. Residual additives are stored in a desiccator for later use.

[0066] Dissolve aloe-emodin in absolute ethanol to prepare a 0.005 mg / mL emodin ethanol solution, and store it at 4°C for later use.

[0067] Place the spare polypropylene nonwoven fabric in a 5mL small bottle with a lid, add 1mL glutaraldehyde solution with a volume fraction of 25%, shake it in a water bath at 80°C at 150rpm for 150min, take it out and wash it with deionized water to dry. Then place it in 0.5mL polyethyleneimine solution with a volume fraction of 15%, shake in a water bath at 50°C at 150rpm for 60min, remove the residual polyethyleneimine solution on the surface with deionized water, and d...

Abstract

The invention relates to the field of non-woven fabric, and discloses antibacterial non-woven fabric, and a preparation method and application of the antibacterial non-woven fabric. The antibacterial non-woven fabric has good antibacterial effect on gram positive bacteria, gram negative bacteria and fungi; the preparation method is simple, the cost is low, no harmful substances are generated, and promotion and application are facilitated. The antibacterial non-woven fabric is prepared from polypropylene non-woven fabric, aloe-emodin, glutaraldehyde and polyethylenimine. The invention also discloses the preparation method of the antibacterial non-woven fabric and the application of the antibacterial non-woven fabric in textile industry.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to an antibacterial non-woven fabric and its preparation method and application. Background technique [0002] Non-woven fabric (Non-woven Fabric, NWF), also known as non-woven fabric, is a kind of cloth-like material that is processed by needle rolling machine or carding machine, formed or bonded with high pressure. The difference between non-woven fabrics and other general plastic films or cloths lies in their production process, and their basic materials are almost the same, such as PVC (polycinyl chloride), PE (polyethylene), EVA (ethylene vintlacetate), PVA (polyvinyl alcohol), PP (polypropylene), PET (polyethylene terephthal), etc. In terms of material properties, non-woven fabrics have a large surface area, no chip shedding, and low resistance to reactants and products. It is a hydrophobic polymer material with good mechanical strength. [0003] Polypropylene non-woven fabr...
