Description
Technical Field
The invention relates to the technical field of finishing agents, in particular to a preparation method and application of photodynamic anti-virus clothing finishing liquid.
Background
With the development of science and technology and the increasing improvement of human living standard, people pay more and more attention to health, the cleaning of clothes and textiles is a very concerned problem, and the cleaning of clothes not only includes removing visible dirt such as oil stain and dust, but also includes removing or killing various pathogenic bacteria and viruses harmful to human bodies. Ordinary daily cleaning only can remove stains and cannot kill pathogenic bacteria or even viruses, so people need to use special bactericides to kill bacteria. In order to control the infection of bacteria and drug-resistant germs, cut off the transmission path and protect the susceptible people, medical institutions also adopt various disinfection and sterilization means, wherein a large amount of chemical disinfectants are used. With the advent of new disinfectants, the traditional disinfectants are continuously developing during the renewal. However, the long-term use of a large amount of various disinfectants still causes the bacteria to gradually generate drug resistance, namely disinfectant resistance under the wide selection pressure.
In 2020, the new coronavirus epidemic situation is outbreaked in a large scale in the world, and great threats are brought to the life safety and body health of people in all countries in the world. At present, some common antibacterial finishing agents are available in the market, the antibacterial technology mainly adopts substances such as silver, titanium dioxide, zinc oxide, traditional Chinese medicines for antibiosis, methylisothiazolinone and the like for antibiosis, and the antibacterial fabric formed by combining the antibacterial technology and the fabric generally has the problems of low drug-resistant antibacterial efficiency, complex preparation process, low safety and the like, and is difficult to effectively kill viruses. The CN201110409823.6 patent provides a preparation method of a nano-silver antibacterial fabric, but the nano-silver needs to be dissolved out to be effective in antibacterial. The CN201510594185.8 patent provides a preparation method of an antibacterial fabric, wherein the antibacterial fabric comprises 82-85 parts of bamboo fiber, 2-4 parts of waterborne amino acid modified polyurethane, 5-13 parts of fluoroacrylate polymer, 1-2 parts of nano zinc oxide, 1-2 parts of nano jade powder, 2-5 parts of microporous lignocellulose and 0.5-1.5 parts of dispersing agent, but the problems of complex composition of the antibacterial fabric, low antibacterial efficiency and the like exist. The patent CN200410019096.2 provides a combined nano-antibacterial fabric, which explains a nano-composite fabric with silver series antibacterial agent, nano-zinc oxide and titanium dioxide having adsorption function.
On the other hand, with the advent of multidrug-resistant bacteria, Photodynamic Antibacterial Chemotherapy (PACT) has received increasing attention. The method utilizes the interaction of photosensitizer and light with specific wavelength to generate cell active substance (free radical or singlet oxygen) to kill pathogenic bacteria. The photosensitizer, as an antimicrobial substance, also comes into the sight of people. Compared with the traditional antibacterial finishing agent, the photodynamic antiviral finishing agent has the following advantages: (1) the antibacterial spectrum is wide, can be used for bacteria, fungi, protozoa and the like, and is also effective for drug-resistant strains and viruses; (2) the diffusion distance of the cell active substance produced by the method is short and is inactivated within <100 angstroms, thus avoiding damage to adjoining host tissues; (3) the photosensitizer can reach the infected part through various administration modes, and pathogenic microorganisms cannot generate tolerance to PACT after multiple treatments; (4) the photosensitizer has low toxic and side effects and small influence on liver and kidney functions; (5) it also has inactivation effect on toxic factors secreted by microorganisms. Therefore, PACT is expected to become one of the methods for killing drug-resistant bacteria or a safe alternative to the conventional antibacterial treatment.
However, the photosensitizer is generally limited by the light source to be used in a wider range, and the introduction of the light source in the using process can limit the application range and the field and increase the cost; the structure, application range and field of the related light source equipment are restricted in the application process. Therefore, the means of using photosensitive molecules for antibiosis and antivirus under indoor and outdoor natural light or lamplight is very limited at home and abroad at present, and the development of the application of photodynamic antibiosis technology is restricted.
Therefore, the preparation method and the application of the photodynamic antiviral clothing finishing liquid are problems to be solved urgently by the technical personnel in the field.
Disclosure of Invention
In view of the above, the invention provides a preparation method and application of photodynamic anti-virus clothing finishing liquid, and the anti-virus finishing liquid has high anti-virus and anti-drug-resistant bacteria effects, simple treatment process, simple components and high safety, and is suitable for simple clothing finishing and large-scale production; can realize high efficiency and broad-spectrum killing, can also kill viruses and drug-resistant bacteria without generating drug resistance, has low toxicity and safety, and can be used for preventing super germ infection and blocking cross infection of drug-resistant bacteria in hospitals and related community infection.
In order to achieve the purpose, the invention adopts the following technical scheme:

Further, the polylysine photosensitive molecule is formed by coupling polylysine with a photosensitizer through an amido bond formed between an amino group of the polylysine and a carboxyl group of the photosensitizer.
Further, the photosensitizer has a carboxyl group, and is phthalocyanine or a derivative thereof, porphyrin or a derivative thereof, and boron dipyrrole or a derivative thereof.
Further, the phthalocyanine or the derivative thereof with carboxyl is tetracarboxyl substituted phthalocyanine or a derivative thereof.
Furthermore, the photosensitizer absorbs photons and transfers energy to oxygen molecules which can not absorb the photons when exerting antiviral and antibacterial activities, so that the oxygen molecules are promoted to generate photodynamic reactions, and the photosensitizer does not participate in chemical reactions and is restored to the original state. Therefore, various photosensitizers can be used in the present invention. In order to couple the photosensitizer to the amino group (including the terminal amino group and the α -amino group) of pentapolylysine, it is necessary to first substitute the photosensitizer with a carboxyl group, or to synthesize a photosensitizer having a carboxyl group. Photosensitizers useful in the present invention include, but are not limited to: phthalocyanine with carboxyl group and its derivatives, porphyrin with carboxyl group and its derivatives, and boron dipyrromethene (BODIPY) with carboxyl group and its derivatives.

Furthermore, the penta-polylysine has a large number of positive charges, and the amino group of the penta-polylysine can be used as a binding site of a modifying group and is coupled with a photosensitizer with a carboxyl group through an amido bond. Finally, through covalent combination of amido bonds between the penta-polylysine and the photosensitizer with carboxyl, the photodynamic antibacterial photosensitive molecule of the beta-monocarboxyl substituted zinc phthalocyanine-penta-polylysine coupling compound is formed. The antiviral finishing liquid prepared by matching the penta-polylysine-photosensitizer and the thickening agent is applied to clothes made of different fabrics to form the antibacterial fabric suitable for strong light sources, weak light sources and no light sources, and the antiviral finishing liquid is widely applied to medical work clothes, hotel linen, household linen, personal clothes and the like.
