Description
Technical Field
The invention relates to the technical field of textiles, in particular to a preparation method and application of a photodynamic anti-virus fabric.
Background
With the development of industrial economy, environmental pollution caused by industrial production is becoming serious day by day, and the living space of people faces huge challenges. To control viral transmission, bacterial and drug-resistant pathogen infection, cut transmission pathways, and protect susceptible people, various disinfection and sterilization approaches have been used, including the use of large amounts of chemical disinfectants. 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 leads to the gradual generation of drug resistance, namely disinfectant resistance, of bacteria under the wide selection pressure.
The emergence of MRSA anti-disinfectant strains has been reported in the 50 s of the 20 th century. In 1991, Cookson et al in UK used chlorhexidine hand sanitizer to perform absorption sterilization rate tests on methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA), and the results showed that the MIC of chlorhexidine to MRSA was higher than that of MSSA. The development time of antibiotics is 10-15 years generally, and the abuse of antibiotics, the cultivation of drug-resistant bacteria and even pan-drug-resistant bacteria, the drug-resistant bacteria become important pathogenic bacteria of hospital infection gradually. At present, some antibacterial fabrics are common in the market, the antibacterial technology mainly adopts silver, titanium dioxide, zinc oxide, traditional Chinese medicine antibacterial substances, methylisothiazolinone and other substances for antibiosis, and the antibacterial fabric formed by combining the antibacterial technology and the fabrics generally has the problems of low anti-drug and antibacterial effects, 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 fluoro-acrylic acid ester 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 a 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 agent, the photodynamic antibacterial method 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 the tolerance condition 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 use of the photosensitizer in a wider range is generally limited by the light source, and the cost is increased by introducing the light source in the use process; the application process brings structural restriction of related equipment. Therefore, the means of using photosensitive molecules for antibiosis under a natural light source and even under indoor lamplight is limited at present, and the development of the application of the photodynamic antibiosis technology is restricted.
Therefore, the preparation method and the application of the photodynamic antiviral fabric are problems to be solved by technicians in the field.
Disclosure of Invention
In view of the above, the invention provides a preparation method and application of a photodynamic antiviral fabric, the preparation process is simple, the prepared fabric has high antiviral and drug-resistant bacterium resisting effects and high safety, can realize high-efficiency and broad-spectrum killing, can kill viruses and drug-resistant bacteria without generating drug resistance, meets the requirements of low-toxicity and safety, and can be used for preventing super-germ infection of wounds 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:
a preparation method of a photodynamic antiviral fabric comprises the following specific steps:
(1) spreading the fabric on a conveyor belt of a machine;
(2) conveying the fabric through a conveying belt, and distributing an antiviral system on the fabric; the anti-virus system comprises 0.0001-10% of penta-polylysine photosensitive molecules (anti-virus auxiliary agents), 0.0001-10% of finishing agents and the balance of water; the content of the antiviral auxiliary agent is 0.0001-10%, so that the fabric attached with the antiviral auxiliary agent has sufficient antibacterial efficiency; the content of the finishing agent is 0.0001-10%, and the effective combination of the antiviral auxiliary agent and the antiviral fabric in an antiviral system is ensured.
(3) Drying the fabric distributed with the antiviral system; the drying temperature is 100-150 ℃.
Further, the fabric in the step (1) is one of non-woven fabric, cotton cloth, gauze and modal fabric.
Furthermore, the fabrics used in hospitals are generally wood fiber non-woven fabrics, cotton fiber non-woven fabrics, bamboo fiber non-woven fabrics, hemp fiber non-woven fabrics, carbon fiber-containing non-woven fabrics, PP rayon non-woven fabrics, PVC rayon non-woven fabrics, blend fiber non-woven fabrics, PET non-woven fabrics, PP non-woven fabrics, hemostatic sponges, medical absorbent cotton, medical absorbent gauze, cotton fabrics and modal fabrics.
Further, the transmission speed of the conveyor belt in the step (2) is 0.1-15m/s, so that the antiviral auxiliary agent and finishing agent compound system can be ensured to be in sufficient contact with the fabric, and meanwhile, the production efficiency is improved.
Further, the process for distributing the antiviral system on the fabric in the step (2) is one of spraying, printing and dyeing and dip-dyeing.
Further, the penta-polylysine photosensitive molecule in the step (2) is formed by coupling penta-polylysine with a photosensitizer through an amido bond formed between the amido of the penta-polylysine and the carboxyl of the photosensitizer. The polymerization degree of the pentapolylysine is 5.
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.
Further, the phthalocyanine or the derivative thereof with carboxyl is tetracarboxyl substituted phthalocyanine or a derivative thereof.
Further, the penta-polylysine photosensitive molecule in the step (2) is a beta-monocarboxyl substituted zinc phthalocyanine-penta-polylysine coupling compound, and the chemical structural formula is as follows:
further, the finishing agent in the step (2) is an emulsifier with HLB value of 3-6W/O and an emulsifier with HLB value of 8-18O/W.
Further, the emulsifier of HLB value 3-6W/O type is a nonionic emulsifier of HLB value 3-6, an anionic emulsifier of HLB value 3-6, and a cationic emulsifier of HLB value 3-6.
Further, the nonionic emulsifier with HLB value of 3-6 is one of propylene glycol fatty acid ester, glyceryl monostearate, hydroxylated lanolin, polyoxyethylene oleyl ether, and hydroxypropyl methylcellulose.
Further, the emulsifier of HLB value 8-18W/O type is a nonionic emulsifier of HLB value 8-18, an anionic emulsifier of HLB value 8-18, and a cationic emulsifier of HLB value 8-18.
Further, the nonionic emulsifier with HLB value of 8-18 is one of castor oil/hydrogenated castor oil and ethylene oxide condensate, polyoxyethylene dioleate, polyoxyethylene lanolin alcohol ether, and polyoxyethylene cholesterol ether.
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, the photodynamic antibacterial photosensitive molecule of the penta-polylysine-photosensitizer is formed through the covalent combination of amido bonds between the penta-polylysine and the photosensitizer with carboxyl. The penta-polylysine-photosensitizer and the finishing agent are proportioned and finished on different fabrics to form the antiviral fabric suitable for strong light sources (such as laser or LED light sources), indoor and outdoor natural light and lamplight and under the condition of no light source, and the antiviral fabric is applied to antiviral medical work clothes, antiviral gauze, antiviral air filter materials and antiviral water filter materials.
