Description

Technical Field

[0001] The invention relates to the technical field of textile fabric processing, and in particular to a method for processing a rapid anti-viral, anti-bacterial and washable textile fabric. Background Art

[0002] In the human living environment, bacteria, viruses and other microorganisms are mainly transmitted through saliva, droplets and contact. They are small in size and highly contagious, posing a serious threat to human health.

[0004] At present, the production technology of antibacterial textile fabrics is relatively mature. It mainly relies on antibacterial finishing liquids such as silver, copper, zinc ions, quaternary ammonium salts, and biguanide salts to be applied to textile fabrics through dipping and coating. Although the fabrics can have excellent antibacterial properties, the antiviral protection effect is not obvious.

[0005] CN114635289A discloses an antibacterial composite fabric and a preparation method thereof, wherein the raw fabric is immersed in an antibacterial agent at a temperature of 60-80°C for a reaction time of not less than 1 hour. After the reaction is completed, the fabric is pre-formed at 110°C using an open-width setting machine and dehydrated and dried to obtain the antibacterial composite fabric. However, during the preparation process, the surface of the composite fabric cannot be treated to improve its surface properties, the adhesion between the antibacterial substance and the surface of the composite fabric is poor, and the use effect of the antibacterial substance cannot be guaranteed.

[0006] CN105172272A discloses an antibacterial, waterproof and breathable composite fabric and a preparation method thereof, wherein an antibacterial agent silver-loaded rectorite is arranged in the components of a polyether thermoplastic polyurethane film, thereby enhancing the sterilization rate against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Aspergillus niger, but the antibacterial substances thereof are easy to agglomerate, thereby reducing the antibacterial effect of the composite fabric and shortening the service life of the composite fabric.

[0007] As the environment people face becomes more and more complex, the requirements for textile fabrics are getting higher and higher. How to prepare a textile fabric with strong antiviral and antibacterial effects, high adhesion strength, washing resistance and long service life has become a technical problem that needs to be solved at present. Summary of the invention

[0008] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a rapid antiviral, antibacterial and washable textile fabric treatment method.

[0009] A rapid antiviral and antibacterial washable textile fabric treatment method comprises the following steps: S1, treating the textile fabric with ammonia plasma for 10-30s to obtain a pretreated textile fabric; S2, adding amino-terminated polyamidoamine to N,N-dimethylformamide and stirring evenly, adding silver nitrate thereto and stirring in dark for 1-2 hours, adding sodium borohydride and stirring for 5-10 hours, adding 1-ethyl-(3-dimethylaminopropyl)carbodiimide and 1-hydroxybenzotriazole and stirring evenly to obtain a pretreatment solution; S3, adding chitosan solution to the pretreatment solution, stirring at 40-60°C for 1-2h after the addition is complete, removing N,N-dimethylformamide by rotary evaporation, dialyzing for 20-30h, adding penetrant and softener to the dialyzed solution and stirring evenly to obtain a finishing solution; S4. The pretreated textile fabric is dipped into the finishing liquid by a one-dip-one-roll method, and then baked at 150-170° C. for 1-2 minutes and cooled to room temperature.

[0010] Preferably, in S1, the discharge power is 100-120W.

[0011] Preferably, in S2, the number of generations of the amino-terminated polyamide-amine is 1.5-2.5 generations.

[0012] Preferably, in S2, the mass ratio of amino-terminated polyamidoamine, silver nitrate, sodium borohydride, 1-ethyl-(3-dimethylaminopropyl)carbodiimide, and 1-hydroxybenzotriazole is 5-10: 0.1-1: 0.1-1: 0.01-0.15: 0.01-0.2.

[0013] Preferably, in S3, the mass ratio of the pretreatment liquid, the chitosan solution, the penetrant, and the softener is 55-110:15-30:1-2:1-3.

[0014] Preferably, in S3, the chitosan solution is an acetic acid aqueous solution of chitosan, which is obtained by adding chitosan to an acetic acid aqueous solution with a concentration of 0.5-1.2 mol / L and stirring evenly, wherein the mass ratio of chitosan to the acetic acid aqueous solution is 1:40-50.

[0017] A rapid antiviral and antibacterial washable textile fabric is prepared by adopting the rapid antiviral and antibacterial washable textile fabric treatment method. Beneficial Effects

[0018] The invention introduces active amino groups into the textile fabric surface by performing amino plasma treatment on the textile fabric surface, which not only enhances the reaction activity of the textile fabric but also makes the surface present a rough structure, making it easier to fully impregnate and adsorb the finishing liquid in the subsequent padding process.

[0019] The amino-terminated polyamide-amine used in the present invention has a similar cavity structure inside, and its branched end has a large number of active amino groups, which can coordinate with silver ions, so that the silver ions have excellent dispersion performance thereon, and then through the action of sodium borohydride, nano silver is in situ generated on the branched structure of the amino-terminated polyamide-amine, which has high bonding strength and excellent dispersion performance.

[0020] The present invention further combines the hydrophilic natural polysaccharide chitosan at the end of the amino-terminated polyamide-amine, which can not only further enhance the coating and bonding strength of the nanosilver, but also has extremely high bonding strength with the pretreated textile fabric. The highly branched structure of the amino-terminated polyamide-amine can significantly increase its contact effect with bacteria / viruses. It has been confirmed through experiments that the present invention can achieve the purpose of high-efficiency antibacterial and antiviral, and can also prevent the fabric from falling off after washing, and the fabric has excellent antibacterial durability.

[0021] The amino-terminated polyamide-amine used in the present invention has excellent hydrophilicity, and can be used as a booster to promote the surface-loaded nanosilver and chitosan to quickly destroy viruses on the surface of textile fabrics, and has a long-term inhibitory effect on various pathogenic microorganisms. At the same time, the method is reasonably designed and easy to operate. The obtained textile fabric is soft and washable, and has long-lasting antibacterial and antiviral effects. It can be widely used in the field of clothing fabrics and has high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Referring to ISO 18184 "Determination of antiviral activity of textile products", the rapid antiviral, antibacterial and washable textile fabrics obtained in Example 5 and Comparative Examples 1-2 were immediately subjected to antiviral tests. The test strain was enveloped virus H1N1, and the untreated textile fabrics were used as the control group. After each group of samples was exposed to the test strain for 1 min, 2 min, 5 min and 10 min, the logarithmic value of the virus titer of each group was measured, and the antiviral activity value M was calculated. v (M v The larger the value, the better the antiviral effect).

[0036] M v =(U t -U0)-(A t -U0) U0 is the logarithmic value of the average virus titer recovered at time 0 in the control group; U t A is the logarithmic value of the average virus titer recovered in the control group after a certain period of time; t It is the logarithmic value of the average virus titer recovered in each group after a certain period of time.

[0037] like Figure 1 As shown, the antiviral activity value of the rapid antiviral, antibacterial and washable textile fabric obtained in Example 5 is higher than 3.0 at 1 minute and higher than that of Comparative Examples 1-2 (P < 0.05). At the same time, its antiviral activity value further increases with time.

[0038] The antibacterial rates of the rapid antiviral and antibacterial washable textile fabrics obtained in Example 5 and Comparative Examples 1-2 were tested with reference to GB / T 20944.3-2008 "Evaluation of Antibacterial Properties of Textiles Part 3: Oscillation Method". Staphylococcus aureus (ATCC6538), Escherichia coli (ATCC 11229) and Candida albicans (ATCC 10231) were used as the test strains.

[0039] like Figure 2 As shown, the antibacterial rates of the fast antiviral, antibacterial and washable textile fabrics obtained in Example 5 and Comparative Examples 1-2 were both higher than 97%, and the antibacterial rates of the fast antiviral, antibacterial and washable textile fabrics obtained in Example 5 were slightly higher than those in Comparative Examples 1-2, but there was no significant difference (P>0.05).

[0040] Referring to the washing method in 10.1.1 Washing color fastness tester in GB / T 20944.3-2008 "Evaluation of antibacterial properties of textiles Part 3: Oscillation method", the rapid antiviral and antibacterial washable textile fabrics obtained in Example 5 and Comparative Examples 1-2 were washed. After washing for a certain number of times, the antiviral activity value (contact test envelope virus H1N1 for 30 minutes) and the antibacterial rate (using Staphylococcus aureus ATCC 6538 as the test strain) were measured again.

[0041] like Figure 3 and Figure 4 As shown, with the increase of washing times, the antiviral activity value and antibacterial rate of the rapid antiviral and antibacterial washable textile fabric obtained in Example 5 are always higher than those in Comparative Examples 1-2 (P < 0.05).

[0042] The applicant believes that this is because the present invention introduces active amino groups on the surface of textile fabrics by treating the surface of textile fabrics with amino plasma, which can not only enhance the reaction activity of textile fabrics, but also present a rough structure on the surface, which is easier to fully impregnate and adsorb the finishing liquid in the subsequent padding process. The amino-terminated polyamide-amine used in the present invention has a similar cavity structure inside, and its branched end has a large number of active amino groups, which can coordinate with silver ions, so that the silver ions have excellent dispersion performance on it. Then, after the action of sodium borohydride, nano silver is generated in situ on the branched structure of the amino-terminated polyamide-amine, with high binding strength and excellent dispersion performance. The present invention further combines chitosan, a natural polysaccharide with strong hydrophilicity, at the end of the amino-terminated polyamide-amine, which can not only further enhance the coating and binding strength of nano silver, but also has extremely high binding strength with the pretreated textile fabric. The highly branched structure of the amino-terminated polyamide-amine can significantly increase its contact effect with bacteria / viruses, achieve the purpose of high-efficiency antibacterial and antiviral, and at the same time, it can avoid the phenomenon of falling off of the fabric after washing, and the fabric has excellent antibacterial durability.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
