Technical Field

The invention relates to the technical field of fabric finishing, in particular to an antiviral finishing agent and a preparation method and application thereof.

Background

Harmful microorganisms (bacteria/viruses) in living environments are ubiquitous and are at any time threatening the health and life of human beings. Many textiles may be infected with various pathogenic bacteria or viruses during production, storage and transportation, and in special environments (such as hospitals, epidemic areas or beauty/sauna and other special industries), the pathogenic bacteria or viruses can infect human bodies through the textiles (clothing). With the improvement of the requirements of people on living quality and the pursuit of healthy life, textiles with antibacterial and antiviral functions are more and more favored by people. At present, antibacterial textiles with various brands and models are on the market, but many textiles can only resist bacteria but not viruses.

As reported by microbiologists, the virus is transmitted through the patient's tissues when talking, sneezing and/or coughing. When flying through air to a surface such as a garment system, if the surface layer of the garment system is hydrophilic, it will be absorbed by the garment system, penetrating the garment system due to the capillary effect. This situation becomes very dangerous especially when the mask or protective clothing becomes wet by high humidity breathing from the mouth or nose, where the garment system may become a collector of viruses. Therefore, a finishing agent with an antiviral function is urgently needed to be applied to the textile (clothing) industry.

Disclosure of Invention

The invention aims to provide an antiviral finishing agent, and a preparation method and application thereof, so as to overcome the defects of the prior art.

The technical scheme for solving the technical problem is as follows: an antiviral finishing agent comprises the following components in parts by weight: 30-50 parts of guanidine compounds; 10-20 parts of an organosilicon quaternary ammonium salt compound; 5-10 parts of metal salt; 50-80 parts of water.

The guanidine compound is at least one of biguanide and monoguanidine.

The organosilicon quaternary ammonium salt compound is at least one of 3-trimethoxysilylpropyl octadecyl dimethyl ammonium chloride, 3-dimethoxy methylsilylpropyl octadecyl dimethyl ammonium chloride and 3-methoxy dimethylsilyl propyl octadecyl dimethyl ammonium chloride.

The metal salt is at least one of silver stearyl glutamate, silver nitrate, zinc sulfate and zinc nitrate.

The preparation method of the antiviral finishing agent comprises the following steps: and uniformly mixing the guanidine compound, the organic silicon quaternary ammonium salt compound, the metal salt and water to obtain the antiviral finishing agent.

The application of the antiviral finishing agent in preparing antiviral textiles comprises the following steps: the anti-virus finishing agent with a certain concentration is finished on cotton fabrics or chemical fibers and blended fabrics thereof by a padding or dipping method, and then the cotton fabrics or the chemical fibers and the blended fabrics are dried at 100-110 ℃ and baked at 140-170 ℃ for 0.5-2 min, so that the anti-virus textiles are obtained.

The invention has the beneficial effects that:

through the synergistic effect of the three main components in the antiviral finishing agent, the finished textile has excellent antiviral effect which is not possessed by the conventional single component, and the antiviral activity rate of the textile on influenza A virus H3N2 is as high as 99.95%.
