Problems solved by technology

[0007] However, if the above-mentioned antibacterial agent is directly coated on the surface of the textile, the textile will have an antiviral effect before washing
However, after washing, the pharmaceutical ingredients on the surface of the textile will dissolve in water and fall off
After washing, the antiviral effect of textiles is greatly reduced

preparation example Construction

[0024] A preparation method of an antibacterial and antiviral auxiliary agent for textiles, comprising the following steps: mixing substance A, substance B, substance C and substance D, and mixing uniformly to obtain a finished auxiliary agent.

[0025] Textiles are made of fibers and can be divided into many categories according to the different raw materials. Textiles of the present invention can use natural fibers or semi-natural fibers such as cellulose fibers (kapok, hemp, rayon, pulp, etc.), protein fibers (wool, silk, etc.), and polyamide fibers, polyester fibers, etc. Synthetic fibers such as polypropylene fibers, polyvinyl alcohol fibers, polyvinyl chloride fibers, polyvinylidene chloride fibers, polyolefin fibers, and polyurethane fibers.

[0026] Select 150D*150D twill weave polyester fabric as the base fabric, impregnate the base fabric with the above-mentioned additives, and remove excess additives with a small paddle. The liquid-carrying rate of the additive is ...

Embodiment 1

[0030] An antibacterial and antiviral auxiliary agent for textiles, including substance A, substance B, substance C and substance D, wherein substance A is 5% benzalkonium chloride, substance B is polyhexamethylene biguanide hydrochloride 5%, and substance C The substance is 10% of nanocellulose, and the substance D is 80% of water. After mixing, the finished auxiliary agent is obtained. The fabric is prepared according to the above method, and then washed according to the above washing method.

Embodiment 2

[0032] An antibacterial and antiviral auxiliary agent for textiles, including substance A, substance B, substance C and substance D, wherein substance A is 2% of benzalkonium chloride, 1% of benzalkonium bromide, 2% of benzethonium chloride, and substance B It is polyhexamethylene biguanide hydrochloride 5%, polyhexamethylene guanidine hydrochloride 5%, substance C is 10% of nanocellulose, substance D is 75% of water, and the finished auxiliary agent is obtained after mixing, and prepared according to the above method fabric, then wash as above.

Abstract

The invention discloses an antibacterial and antiviral auxiliary agent for textiles, which comprises substance A, substance B, substance C and substance D, wherein the ratio of substance A: substance B: substance C is 1-10:1-20:1-20 . The present invention adopts the above-mentioned antibacterial and antiviral auxiliary agent for textiles. By introducing the carrier, the carrier forms a chelate body with quaternary ammonium salts and guanidines, so that the surface of the fabric obtains an antiviral function with a washing-resistant effect.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to an antibacterial and antiviral auxiliary agent for textiles and a preparation method and application thereof. Background technique [0002] According to the World Health Organization Interim Guidance Document on Cleaning and Disinfecting Surfaces for the Epidemic of Novel Coronavirus: Coronavirus disease 2019 (COVID-19) is a respiratory infection caused by SARS-CoV-2 (COVID-19 virus). The COVID-19 virus is primarily transmitted through close physical contact and respiratory droplets, but may also be airborne during aerosol-generating medical procedures. Like other coronaviruses, SARS-CoV-2 is an enveloped virus with a fragile outer lipid envelope, making it easier to Hazardous by disinfectants. Several studies have assessed the persistence of the COVID-19 virus on different surfaces. One study found that the COVID-19 virus survived for 1 day on cloth and w...
