Description

Technical Field

[0001] The present application relates to the field of textile manufacturing and antibacterial technology, and in particular to an antibacterial textile and a preparation method thereof. Background Art

[0002] With the advancement of science and technology and the improvement of people's living standards, consumers' demand for textiles is no longer limited to a single function, but pursues textiles with higher performance and more functions. Recently, due to the increase in consumers' attention to protective textiles, especially the significant increase in demand for antibacterial and antiviral products, antibacterial and antiviral textiles on the market have received widespread attention. Especially under the influence of the "plum rain season", antibacterial, antiviral and mildew-proof fabrics have become an important development direction for the textile industry. Although there are already a wide range of antibacterial and mildew-proof textiles on the market, textiles that can simultaneously have antibacterial, mildew-proof and anti-fouling functions are still relatively rare. In addition, although the recently popular antiviral textiles are popular, they also have problems such as low antibacterial effect, poor anti-fouling effect and poor washing resistance. Summary of the invention

[0003] In order to solve at least one of the above technical problems, an antibacterial textile having antibacterial and antifouling properties and a long antibacterial effect period is developed. The present application provides an antibacterial textile and a preparation method thereof.

[0004] In a first aspect, the present application provides an antibacterial textile, wherein the antibacterial textile is obtained by padding the textile in a padding solution; the padding solution comprises the following raw materials in parts by weight: 100-130 parts of water; 4-8 parts of cocamidopropyl betaine; 8-16 parts of antibacterial microcapsules; γ-aminopropyltriethoxysilane 3-5 parts; 3-7 parts of accelerator; 3-8 parts of softener; The antibacterial microcapsule comprises a capsule core and a capsule wall wrapping the capsule core; The capsule core is composed of capsule core material; The capsule wall is composed of capsule wall material; The capsule core material comprises chitosan, nano silver ions and 2-octyl-2H-furan-5-one in a weight ratio of (3-5):(1-3):(1-3); The capsule wall material comprises melamine urea-formaldehyde resin and hydroxypropyl methylcellulose.

[0005] By adopting the above technical scheme, the antibacterial textiles in the present application not only achieve the effect of antibacterial and mildew-proof, but also achieve the effect of antifouling. First, cocamidopropyl betaine helps to improve the adhesion of antibacterial microcapsules on textiles, so that the antibacterial microcapsules can better penetrate into the fiber interior, thereby improving the antibacterial effect and persistence. Secondly, chitosan, nano silver ions and 2-octyl-2H-furan-5-one in the antibacterial microcapsules jointly provide excellent antibacterial effects, and 2-octyl-2H-furan-5-one has a good antifouling effect. The capsule wall materials melamine urea-formaldehyde resin and hydroxypropyl methylcellulose not only provide physical protection for the antibacterial microcapsules, but also can control the release rate of the antibacterial agent and extend the duration of the antibacterial effect. In addition, γ-aminopropyl triethoxysilane (APTES) is used as a coupling agent to improve the bonding force between the antibacterial microcapsules and the textile fibers, and enhance the persistence and washing resistance of the antibacterial effect. The accelerator helps to improve the adhesion efficiency of the antibacterial microcapsules on textiles, further enhancing the antibacterial effect. Finally, the softener improves the feel of the textile, making it softer and more comfortable, and also helps to improve the adhesion stability of the antibacterial microcapsules. In summary, through the synergistic effect of the above components, the antibacterial textile of the present invention not only has excellent antibacterial properties, but also can maintain a long antibacterial lasting period, and also has good antifouling properties, providing consumers with an efficient, long-lasting and comfortable antibacterial textile solution.

[0006] Optionally, the weight ratio of the cocamidopropyl betaine to the antibacterial microcapsule is 1:(1.8-2.4).

[0007] By adopting the above technical scheme, the antibacterial textiles in this application not only achieve the antibacterial and mildew-proof effects, but also achieve the anti-fouling effect. First, the weight ratio of cocamidopropyl betaine to antibacterial microcapsules is set to 1: (1.8-2.4). This ratio helps to improve the adhesion of antibacterial microcapsules on textiles, so that the antibacterial microcapsules can better penetrate into the interior of the fibers, thereby improving the antibacterial effect and durability. Secondly, the chitosan, nano-silver ions and 2-octyl-2H-furan-5-one in the antibacterial microcapsules jointly provide excellent antibacterial effects, among which 2-octyl-2H-furan-5-one also has a good anti-fouling effect. The capsule wall materials melamine urea-formaldehyde resin and hydroxypropyl methylcellulose not only provide physical protection for the antibacterial microcapsules, but also can control the release rate of the antibacterial agent and prolong the duration of the antibacterial effect. In summary, through the synergistic effect of the above components, the antibacterial textiles in this application not only have excellent antibacterial properties, but also can maintain a long antibacterial lasting period, while also having good anti-fouling properties, providing consumers with an efficient, long-lasting and comfortable antibacterial textile solution.

[0008] Optionally, the weight ratio of the cocamidopropyl betaine to the antibacterial microcapsule is 1:2.

[0009] Optionally, the total weight of the cocamidopropyl betaine and the antibacterial microcapsules accounts for 11-14% of the total weight of the antibacterial textile.

[0010] Optionally, the weight ratio of the capsule core material to the capsule wall material is (5-7): (3-5).

[0011] Optionally, the method for preparing the antibacterial microcapsules comprises the following steps: A1, melamine, urea and formaldehyde are mixed and stirred for 3-8 minutes, the pH is adjusted to neutral, hydroxypropyl methylcellulose is added thereto, mixed evenly, and reacted at 65-75° C. for 0.5-1.5 hours to obtain a prepolymer; A2, the acid solution and chitosan are mixed and impregnated, the solvent is removed, the chitosan is washed, and the chitosan is dried to obtain acidified chitosan; nano silver ions, 2-octyl-2H-furan-5-one and ethanol solution are added to the acidified chitosan, mixed evenly, deionized water and an emulsifier are added, and the mixture is reacted at 65-75° C. for 0.5-1.5 hours under stirring to obtain a capsule core emulsion; A3, adding the prepolymer to the capsule core emulsion, stirring for 20-40 minutes, adjusting the pH to 3-4, reacting at 60-70° C. for 2-3 hours to obtain the antibacterial microcapsules.

[0012] By adopting the above technical solution, the antibacterial microcapsules prepared by the above preparation method not only have efficient antibacterial properties, but also have good antifouling effects and a long antibacterial lasting period. These characteristics enable the prepared antibacterial microcapsules to be applied to textiles, providing consumers with an efficient, long-lasting and comfortable antibacterial textile solution. Through the above technical solution, the deficiencies of antibacterial and mildew-proof textiles on the market in terms of antibacterial, mildew-proof and antifouling, as well as the low antibacterial effect, poor antifouling effect and poor washability of the recently popular antiviral textiles are solved.

[0041] Example 1 The present embodiment provides an antibacterial textile, which is obtained by padding the textile in a padding solution (the padding solution temperature is 25° C.; the padding rate after padding is 75%), and further comprises a step of drying and tentering after padding; in this step, the drying temperature is 120° C. and the vehicle speed is 50 m / min; the padding solution comprises the following raw materials by weight: 100 parts of water; 6 parts of cocamidopropyl betaine; 12 parts of antibacterial microcapsules; 3 parts of γ-aminopropyl triethoxysilane; 3 parts of accelerator; 3 parts of softener; The antibacterial microcapsules in this example were prepared by Preparation Example 1.

[0042] The accelerator in this example is BYK-346.

[0043] The softener in this preparation example is hydrogen-containing silicone oil.

[0044] The raw material fiber of the textile in this embodiment is selected from polyester fiber.

[0045] The preparation method of the antibacterial textile in this embodiment comprises the following steps: S1, dividing water into three equal parts; mixing the first part of water with cocamidopropyl betaine to prepare a first mixed material; S2, mixing the second portion of water and γ-aminopropyltriethoxysilane evenly, adding the antibacterial microcapsules for impregnation, washing, and drying to obtain γ-aminopropyltriethoxysilane modified antibacterial microcapsules; S3, mixing the third portion of water with the accelerator and the softener, and adding the first mixed material obtained in step S1 and the γ-aminopropyltriethoxysilane modified antibacterial microcapsules obtained in step S2, and mixing them evenly to obtain a padding solution; S4, padding and finishing the desized or refined deoiled and dried textile in a padding solution to prepare the antibacterial textile.

[0046] Example 2 The difference between this embodiment and embodiment 1 is that, when preparing the antibacterial textile, the total weight of cocamidopropyl betaine and the antibacterial microcapsules is 18 parts, and the weight ratio of cocamidopropyl betaine to the antibacterial microcapsules is 1:1.8.

[0047] Example 3 The difference between this embodiment and embodiment 1 is that, when preparing the antibacterial textile, the total weight of cocamidopropyl betaine and the antibacterial microcapsules is 18 parts, and the weight ratio of cocamidopropyl betaine to the antibacterial microcapsules is 1:2.2.

[0048] Example 4 The difference between this embodiment and embodiment 1 is that, when preparing the antibacterial textile, the total weight of cocamidopropyl betaine and the antibacterial microcapsules is 18 parts, and the weight ratio of cocamidopropyl betaine to the antibacterial microcapsules is 1:2.4.

[0049] Comparative Examples 1-3 Comparative Example 1 The difference between this comparative example and Example 1 is that when preparing the antibacterial textile, an equal amount of cocamidopropyl betaine is used to replace the antibacterial microcapsules.

[0050] Comparative Example 2 The difference between this comparative example and Example 1 is that when preparing the antibacterial textile, an equal amount of antibacterial microcapsules are used to replace cocamidopropyl betaine.

[0051] Comparative Example 3 The difference between this comparative example and Example 1 is that, when preparing the antibacterial textile, an equal amount of nano silver ions is used instead of antibacterial microcapsules.

[0052] Experimental testing: Antibacterial test: The performance of the antibacterial textiles in Examples 1-4 and Comparative Examples 1-3 was tested, wherein the test of the antibacterial rate was based on the standard "GBT20944.3-2008 Evaluation of antibacterial properties of textiles Part 3: Oscillation method". The control sample was based on Section 3.2 of this standard.

[0053] Antifouling performance test (antifouling performance after washing 10 times): Antifouling performance is based on the test standard "FZT 01118-2012 Testing and evaluation of antifouling performance of textiles and ease of stain removal".

[0054] The test of mildew resistance level refers to the standard "GJB 150.10A2009 Military Equipment Environmental Test Method Mold Test". Rating standard: Level 0 no growth, no mold growth on the material; Level 1 trace growth, scattered, sparse or very limited mold growth; Level 2 mild growth, mold on the surface of the material spreads intermittently or colonies are loosely distributed, or hyphae extend continuously on the entire surface, but the surface of the material under the mold is still visible; Level 3 moderate growth, mold grows in large quantities, and the material may show visible structural changes; Level 4 severe growth, heavy mold growth. Anti-mite performance: Anti-mite performance is tested according to the test standard "Q320691KDA77-2020 Anti-mite Bedding".

[0055] The experimental test results of Examples 1-4 and Comparative Examples 1-3 are shown in Table 1.

[0056] Table 1 - Experimental test results of Examples 1-4 and Comparative Examples 1-3 Results analysis: The difference between Examples 2-4 and Example 1 is that when preparing antibacterial textiles, the weight ratio of cocamidopropyl betaine and antibacterial microcapsules is different. Combined with the experimental test data in Table 1, it can be seen that when the weight ratio of cocamidopropyl betaine and antibacterial microcapsules is 1:2, the comprehensive performance of the antibacterial textiles obtained is better. The difference between Comparative Example 1 and Example 1 is that when preparing antibacterial textiles, an equal amount of cocamidopropyl betaine is used to replace antibacterial microcapsules. The difference between Comparative Example 2 and Example 1 is that when preparing antibacterial textiles, an equal amount of antibacterial microcapsules are used to replace cocamidopropyl betaine. Combined with the experimental test data in Table 1, it can be seen that when antibacterial microcapsules and cocamidopropyl betaine are used simultaneously, it has a significant effect on the improvement of concrete antibacterial and anti-fouling. The difference between Comparative Example 3 and Example 1 is that when preparing antibacterial textiles, an equal amount of nano-silver ions are used to replace antibacterial microcapsules. It can be seen from the experimental detection data in conjunction with Table 1 that although nano silver ions have preferably antibacterial properties, as the number of textile washing times increases, the content of nano silver ions that can play an antibacterial role in textiles decreases, and therefore, the duration is shorter, and when nano silver ions are used alone, the effect is relatively single, and a stronger antifouling effect cannot be achieved. The reason may be that although nano silver ions can provide instant antibacterial effects, due to the lack of protection of the capsule wall, nano silver ions are easily lost during the washing process, resulting in a shortening of the antibacterial duration. Meanwhile, nano silver ions themselves do not have antifouling functions, and therefore comprehensive protective properties cannot be provided. In summary, by comparing the above-described embodiments and comparative examples, it can be seen that the reasonable collocation of cocamidopropyl betaine and antibacterial microcapsules is crucial for improving the comprehensive performance of antibacterial textiles, including improving antibacterial effects, extending the antibacterial duration, and enhancing antifouling properties.

[0057] Embodiment 5-6 The difference between Example 5-6 and Example 1 is that when preparing the antibacterial textile, the weight percentages of some components are changed. The difference is shown in Table 2.

[0059] Table 3 - Experimental test results of Examples 5-6 Result analysis: The difference between Examples 5-6 and Example 1 is that when preparing the antibacterial textile, the weight percentages of some components are different. Combined with the experimental test results in Table 3, it can be seen that the comprehensive performance of the antibacterial textile prepared in Example 5 is better.

[0060] Embodiment 7-11 The difference between Examples 7-11 and Example 5 is that when preparing antibacterial textiles, on the premise that the weight ratio of cocamidopropyl betaine to antibacterial microcapsules is 1:2, the total weight ratio of cocamidopropyl betaine and antibacterial microcapsules in the antibacterial textiles is changed, and the optimal weight ratio is selected.

[0061] In Example 5, the total weight of cocamidopropyl betaine and antibacterial microcapsules is 18 parts, and the total weight of the antibacterial textile is 157 parts.

[0062] Therefore, it is not difficult to conclude that in Example 5, the proportion of cocamidopropyl betaine (referred to as variable 1) and antibacterial microcapsules (referred to as variable 2) in the antibacterial textile (referred to as the matrix) is 11.46%.

[0063] The differences between Examples 7-11 and Example 5 are shown in Table 4.

[0064] Proportion = (variable 1 + variable 2) / total weight of matrix * 100%.

[0065] Table 4 - Differences between Examples 7-11 and Example 5 The experimental test results of Examples 7-11 are shown in Table 5.

[0066] Table 5 - Experimental test results of Examples 7-11 Results analysis: The difference between Examples 7-11 and Example 5 is that when preparing antibacterial textiles, the total weight of cocamidopropyl betaine and antibacterial microcapsules in the antibacterial textiles accounts for different proportions. Combined with the experimental test results in Table 5, it can be seen that when the total weight of cocamidopropyl betaine and antibacterial microcapsules in the antibacterial textiles accounts for 14%, the comprehensive performance of the antibacterial textiles prepared is better, and when the total weight of cocamidopropyl betaine and antibacterial microcapsules in the antibacterial textiles accounts for 11-14%, the comprehensive performance of the antibacterial textiles prepared is the best. When the proportion is too high or too low, the comprehensive performance is reduced.

[0067] Examples 12-13 Example 12 The difference between this embodiment and embodiment 10 is that different preparation parameters of the antibacterial microcapsules are used in preparing the antibacterial textiles. The antibacterial microcapsules in this embodiment are prepared by Preparation Example 2.

[0068] Example 13 The difference between this embodiment and embodiment 10 is that different preparation parameters of the antibacterial microcapsules are used in preparing the antibacterial textiles. The antibacterial microcapsules in this embodiment are prepared by Preparation Example 3.

[0069] Table 6 - Experimental test results of Examples 12-13 Result analysis: The difference between Examples 12-13 and Example 10 is that different preparation parameters of antibacterial microcapsules are used in preparing antibacterial textiles. Combined with the experimental test results in Table 6, it can be seen that the antibacterial textile prepared by Example 12 has better comprehensive performance.
