Description

Technical Field

[0001] This application relates to the field of textile technology, and in particular to a mildew-resistant and antibacterial fabric and its production process. Background Technology

[0002] Fabrics are soft, sheet-like materials made by weaving fine, long fibers through specific structural relationships. They are widely used in clothing, medical, and industrial fields. Due to their porous shape and the chemical structure of their polymers, fibrous fabrics become ideal hosts for microorganisms to survive and multiply. These microorganisms not only contaminate the fibers but also pose certain health risks. Anti-mildew and antibacterial fabrics are fabrics that have undergone specific treatments to acquire excellent antibacterial properties. This eliminates odors caused by bacteria, keeps the fabric clean, and prevents the proliferation of bacteria and microorganisms, reducing the risk of secondary transmission and improving the safety and hygiene of the fabric during use.

[0003] There are currently two main methods for antibacterial treatment of fabrics on the market. One method uses metal ions such as copper or silver ions, which have antibacterial effects, as antibacterial agents. The antibacterial agents are directly incorporated into the fabric fibers using spinning-grade antibacterial technology to achieve the antibacterial effect. The other method uses some chemical agents with antibacterial properties to treat the fabric fibers or fabrics, attaching the antibacterial components in the chemical antibacterial agents to the fabric, giving the fabric a certain antibacterial property.

[0004] The second method is still the most commonly used antibacterial treatment method, which uses antibacterial agents to treat fabrics to give them antibacterial properties. However, most common antibacterial agents are applied directly to fabrics by impregnation, resulting in poor adhesion of the antibacterial components to the fabric and making it difficult to achieve a long-lasting antibacterial effect. Summary of the Invention

[0005] In order to improve the long-lasting anti-mildew and antibacterial effect of antibacterial fabrics, this application provides an anti-mildew and antibacterial fabric and its manufacturing process.

[0006] Firstly, this application provides a manufacturing process for anti-mildew and antibacterial fabrics, employing the following technical solution:

[0007] A manufacturing process for an anti-mildew and antibacterial fabric includes the following steps:

[0008] S1. The fiber composition is impregnated in an antibacterial treatment agent and soaked at 45-60°C for 5-8 hours;

[0009] S2. After the fiber composition in step S1 is soaked, it is taken out and dried, and then blended to obtain blended yarn;

[0010] S3. The blended yarn obtained in step S2 is woven to obtain a fabric.

[0011] S4. The fabric obtained in step S3 is subjected to fumigation treatment, and after the fumigation treatment is completed, it is dried to obtain anti-mildew and antibacterial fabric.

[0012] By adopting the above technical solution, the antibacterial and mildew-proof fabric first undergoes antibacterial treatment at the fiber stage. The fiber composition is soaked in an antibacterial treatment agent, and heating is applied during the soaking process. This allows the antibacterial components in the treatment agent to penetrate into the fibers, and some substances react with the fibers, stably adhering to the fibers and between the fibers. After soaking, the fibers are dried, which further enhances the adhesion performance of the antibacterial substances on the fibers. The antibacterial-treated fiber composition is then blended and woven into a fabric, which is then subjected to fumigation treatment. During fumigation, water vapor penetrates into the fibers of the fabric, performing a secondary curing of the antibacterial substances adhering to the fibers. After secondary curing, the fabric exhibits stronger adhesion of the antibacterial substances, and with the penetration of water vapor, the antibacterial substances penetrate deeper into the fabric fibers. The fibers effectively encapsulate and stretch the antibacterial substances, further improving the stability of the antibacterial substances' adhesion to the fabric and enhancing the long-term effectiveness of the fabric's antibacterial properties.

[0013] Optionally, the fiber composition may include at least two of bamboo fiber, hemp fiber, wool fiber, chitosan fiber, and seaweed fiber.

[0014] Preferably, the fiber composition comprises bamboo fiber, hemp fiber, and chitosan fiber; the content of the hemp fiber does not exceed 30%.

[0015] By adopting the above technical solutions, bamboo fiber, hemp fiber, wool fiber, chitosan fiber, and seaweed fiber all possess certain antibacterial properties. Bamboo fiber contains natural antibacterial components such as bamboo quinones, while hemp fiber contains cannabinol, cannabidiol, and cannabinol, which have antibacterial effects. Chitosan fiber contains chitosan, and seaweed fiber contains seaweed polysaccharides, both of which have good antibacterial effects. Mixing these fibers as the base fiber for anti-mildew and antibacterial fabrics further enhances the fabric's antibacterial properties. Furthermore, hemp fiber has a unique pore structure, which is highly conducive to the adsorption of antibacterial substances. Encapsulating the antibacterial substances within the pore structure of the hemp fiber improves the stability of the adsorption. In a further setting, the hemp fiber content should not be too high, as excessive hemp fiber will cause most of the antibacterial substances to adhere to the hemp fibers, reducing the amount of antibacterial substances adhering to other fibers. This results in uneven dispersion of the antibacterial substances on the fabric, affecting the fabric's antibacterial and anti-mildew effects.

[0016] Optionally, the antibacterial treatment agent comprises the following components by weight percentage: 50-65% water, 25-40% plant extract, 5-20% chitosan, 1-10% white bamboo charcoal, and 1-3% surfactant.

[0017] Optionally, the plant extract includes at least one of peony bud extract, aloe vera extract, tea extract, isatis root extract, peppermint extract, and artemisia extract.

[0018] Optionally, the surfactant is either dodecyltrimethylammonium chloride or hexadecyltrimethylammonium chloride.

[0019] By adopting the above technical solution, the effective antibacterial component in the antibacterial treatment agent is plant extract. The alkaloids, organic acids, and various amino acids contained in the plant extract all have good antibacterial effects. Combined with chitosan, it can effectively inhibit bacteria. White bamboo charcoal, as a type of bamboo charcoal, has a certain bactericidal effect. Its fine and porous structure and strong adsorption capacity allow it to adhere well to the fibers of fabrics. It also has a certain adsorption effect on the bactericidal components in the plant extract, which can improve the adhesion of the antibacterial substances to the fibers. The addition of surfactants can improve the adsorption characteristics of the fiber surface and promote the adsorption of antibacterial substances.

[0020] The extracts from the aforementioned plants all contain effective antibacterial components, which can inhibit the growth and reproduction of bacteria and microorganisms on fabrics to a certain extent. When combined with fiber compositions that have antibacterial effects, the resulting fabrics have excellent antibacterial properties. Furthermore, using plant extracts as the main active ingredient in the antibacterial treatment reduces the use of chemically synthesized antibacterial components, resulting in better skin affinity and reduced skin irritation.

[0021] Optionally, the antibacterial treatment agent further includes graphene oxide, which accounts for 35-50 wt% of the plant extract.

[0022] By employing the above technical solution, graphene oxide itself possesses certain antibacterial properties and exhibits good dispersibility in water. Furthermore, graphene oxide has a porous structure with a large specific surface area, resulting in excellent adsorption capacity. Adding it to antibacterial treatment agents can effectively adsorb and disperse antibacterial substances. Moreover, due to the stronger bonding between graphene oxide and the fibers of the fabric, the antibacterial components adsorbed on the graphene oxide surface and then combined with the fiber composition result in antibacterial components on the fabric exhibiting superior adsorption strength and a longer-lasting antibacterial effect.

[0023] Optionally, in step S1, the liquor ratio during impregnation of the fiber composition is 1:(15-25)(g / ml).

[0024] By adopting the above technical solution, during the impregnation process of the fiber composition in the antibacterial treatment agent, if the liquor ratio is too high, the effective antibacterial components in the antibacterial treatment agent will be too dispersed, affecting the efficiency of the antibacterial substances adsorbing onto the fiber; while if the liquor ratio is too low, the antibacterial components will be difficult to disperse evenly on the fiber, and will easily agglomerate, affecting the antibacterial properties of the fabric. Limiting the liquor ratio during the impregnation process of the fiber composition to the above range results in a better impregnation effect.

[0025] Optionally, in step S4, the fumigation agent used for fumigation treatment includes at least one of artemisia annua, peppermint, mugwort, juniper and chrysanthemum.

[0026] By employing the above technical solution, the fumigation agent is soaked in water and then heated and distilled. During the distillation process, some antibacterial substances contained in the plants are extracted in the form of volatile oils and come into contact with the fabric as they are dispersed with the water vapor. Upon contact with the fabric, the volatile oils are adsorbed onto the fabric surface, and some continue to penetrate into the fibers with the water vapor, adhering to the fibers. The antibacterial substances contained in the volatile oils further enhance the antibacterial effect of the fabric. Furthermore, the fumigation treatment further solidifies the antibacterial substances adhering to the fibers, improving the long-term effectiveness of the fabric's antibacterial properties.

[0027] Optionally, in step S4, the fumigation treatment is followed by low-temperature drying at a temperature of 55–65°C.

[0028] Optionally, in step S4, the fumigation treatment time is 6 to 8 hours.

[0029] By adopting the above technical solution and using low-temperature vacuum drying, the evaporation rate of water vapor is relatively slow. During the slow evaporation process, the effective antibacterial components in the volatile oil can be further evenly dispersed on the fabric. Furthermore, it can prevent the effective components in the volatile oil from evaporating with the water vapor at high temperatures, thus affecting the antibacterial properties of the fabric.

[0030] Optionally, before impregnating the fiber composition in step S1, the fiber may be subjected to an ultrasonic treatment step.

[0031] Optionally, during ultrasonic treatment, the ultrasonic power is 200-300W, the ultrasonic frequency is 15-25 seconds every 15 seconds, and the total ultrasonic time is 5-10 minutes.

[0032] By employing the above technical solution, the fiber composition undergoes ultrasonic treatment, causing the fiber cells to open under the cavitation effect of ultrasound, which is more conducive to the adsorption of antibacterial substances onto the fiber. Furthermore, ultrasonic treatment creates activating groups on the fiber surface, which can effectively capture the antibacterial substances in the impregnation solution, allowing the antibacterial substances to be stably adsorbed on the fiber surface. With further optimization, ultrasonic treatment can also be used during the fumigation process in step S4 to improve the stability of the volatile oils adhering to the fabric during fumigation.

[0033] Optionally, before the fumigation treatment in step S4, a plasma treatment step on the fabric is also included.

[0034] Optionally, the plasma used for plasma treatment is nitrogen plasma with a power of 200-300W and a treatment time of 50-80s.

[0035] By employing the above technical solution, plasma treatment of the fabric generates a large number of activated groups, allowing the antibacterial active substances in the volatile oils released during fumigation to be captured and stably fixed on the fabric surface, resulting in a long-lasting antibacterial effect. Furthermore, plasma treatment can remove some stains from the fabric surface, further enhancing the adhesion of the antibacterial substances to the fabric.

[0036] Secondly, this application provides a mildew-proof and antibacterial fabric, which adopts the following technical solution:

[0037] An anti-mildew and antibacterial fabric is prepared by the above method.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. The anti-mildew and antibacterial fabric production process provided in this application involves first soaking the fiber composition in an antibacterial treatment agent, then spinning it into a fabric, and finally subjecting the fabric to fumigation treatment to a secondary curing of the antibacterial substances attached to the fibers. After secondary curing, the antibacterial substances have a stronger adhesion, and with the penetration of water vapor, the antibacterial substances penetrate deeper into the fabric fibers, improving the stability of the antibacterial substances on the fabric and enhancing the long-term effectiveness of the fabric's antibacterial properties.

[0040] 2. This application uses fabric extracts as the main antibacterial treatment agent, which can effectively inhibit and kill bacteria, thus suppressing the growth and reproduction of bacteria and microorganisms on the fabric to a certain extent. Combined with fiber compositions that have antibacterial effects, the resulting fabric exhibits excellent antibacterial properties. Furthermore, using plant extracts as the main effective component of the antibacterial treatment agent reduces the use of chemically synthesized antibacterial substances, resulting in better skin affinity and reduced skin irritation.

[0041] 3. The antibacterial treatment agent of this application also contains graphene oxide, which can play a good role in adsorbing and dispersing antibacterial substances. Furthermore, since the binding effect between graphene oxide and the fibers of the fabric is stronger, the antibacterial components are adsorbed on the surface of graphene oxide and then combined with the fiber composition. The resulting antibacterial components on the fabric have better adsorption fastness and a longer-lasting antibacterial effect.

[0042] 4. The fumigation agent used in this application is an antibacterial plant. After soaking in water, the fumigation agent is heated and distilled. During distillation, some antibacterial substances contained in the plant are extracted as volatile oils and come into contact with the fabric as the steam disperses. Upon contact with the fabric, the volatile oils adhere to its surface, and some penetrate deeper into the fibers with the steam, further adhering to the fibers. The antibacterial substances in the volatile oils further enhance the antibacterial effect of the fabric. Furthermore, the fumigation treatment further solidifies the antibacterial substances adhering to the fibers, improving the long-term effectiveness of the fabric's antibacterial properties.

[0043] 5. The production process of the anti-mildew and antibacterial fabric provided in this application also includes plasma treatment and ultrasonic treatment steps. Through the above treatment, the adhesion of antibacterial components to the fabric and fibers can be improved, making the antibacterial effect of the fabric more effective and long-lasting.

[0075] Example

[0076] Examples 1-6

[0077] The anti-mildew and antibacterial fabrics disclosed in Examples 1-6 differ mainly in the ratio of the antibacterial treatment agent. The specific sources of the antibacterial treatment agent are shown in Table 2, and the specific production process is as follows:

[0083] Example Source of antibacterial treatment agent Example 1 Preparation Example 1 Example 2 Preparation Example 2 Example 3 Preparation Example 3 Example 4 Preparation Example 4 Example 5 Preparation Example 5 Example 6 Preparation Example 6

[0084] Examples 7-8

[0085] The main difference between Examples 7 and 8 and Example 5 is the composition of the plant extract in the antibacterial treatment agent. The antibacterial treatment agent used in Example 7 was derived from Preparation Example 7, and the antibacterial treatment agent used in Example 8 was derived from Preparation Example 8. All other aspects are consistent with Example 5.

[0086] Comparative Example 1

[0087] The difference between this comparative example and Example 1 is that the fiber composition is not impregnated with an antibacterial treatment agent, and the woven fabric is not fumigated. All other aspects remain the same as in Example 1.

[0088] Comparative Example 2

[0089] The difference between this comparative example and Example 1 is that the fiber composition is not impregnated with an antibacterial treatment agent, while all other aspects are consistent with Example 1.

[0090] Comparative Example 3

[0091] The difference between this comparative example and Example 1 is that the fiber composition is not impregnated with an antibacterial treatment agent, and the woven fabric is treated with steam fumigation. Otherwise, it is consistent with Example 1.

[0092] The antibacterial properties of the fabric samples from Examples 1-8 and Comparative Examples 1-3 were tested. The antibacterial properties were tested before washing and after 30 washes. Staphylococcus aureus, Escherichia coli, and Candida albicans were used as test bacteria to test the antibacterial rate of the fabric samples. The test results are shown in Table 3 below.

[0093] The washing process involved 30 washes using a SW-12D type water fastness tester, and the antibacterial performance was tested according to GB / T 20944.3-2008 "Evaluation of antibacterial properties of textiles - Part 3: Vibration method".

[0094] Table 3: Antibacterial performance test results of Examples 1-8

[0095]

[0096] As can be seen from the data in Examples 1-6, Comparative Examples 1-3 and Table 3, the anti-mildew and antibacterial fabric produced by the process provided in this application, after impregnation of the fibers with antibacterial treatment agent and fumigation treatment, gives the fabric good anti-corrosion and antibacterial properties. Before washing, the fabric can achieve an inhibition rate of more than 90% against Staphylococcus aureus, Escherichia coli and Candida albicans, and after 30 washes, the inhibition rate of the fabric can still be maintained at more than 85%, and the antibacterial properties are long-lasting.

[0097] In Examples 7 and 8, some optimizations and adjustments were made to the composition of the plant extracts. As can be seen from the data in Table 3, the antibacterial performance of the fabric was further improved after optimizing the composition and ratio of the plant extracts in the antibacterial treatment agent.

[0098] Examples 9-12

[0099] The main difference between Examples 9-12 and Example 5 is that graphene oxide was also added to the antibacterial treatment agent. The antibacterial treatment agent used in Example 9 was derived from Preparation Example 9, the antibacterial treatment agent used in Example 10 was derived from Preparation Example 10, the antibacterial treatment agent used in Example 11 was derived from Preparation Example 11, and the antibacterial treatment agent used in Example 12 was derived from Preparation Example 12. All other aspects remained the same as in Example 5.

[0100] The antibacterial performance test results of the fabric samples in Examples 9-12 are shown in Table 4 below.

[0101] Table 4: Antibacterial performance test results of Examples 9-12

[0102]

[0103] Examples 9-12, based on Example 5, added graphene oxide to the antibacterial treatment agent. Comparing the data in Table 4 with the test data of Example 5, it can be seen that the antibacterial performance of the fabric was further improved after the addition of graphene oxide. More importantly, the antibacterial components adhered better to the fabric. After 30 washes, the loss of antibacterial performance of the fabric was significantly reduced. The reason for this may be that the special structure of graphene oxide makes the antibacterial substances adhere more firmly to the fabric.

[0104] Example 13

[0105] The difference between this embodiment and Embodiment 5 is that the fiber composition includes bamboo fiber, hemp fiber, and chitosan fiber, wherein the chitosan fiber accounts for 15 wt%, the hemp fiber accounts for 30 wt%, and the remainder is bamboo fiber. All other aspects remain the same as in Embodiment 5.

[0106] Example 14

[0107] The difference between this embodiment and Embodiment 13 is that the chitosan fiber content is 10 wt%, the hemp fiber content is 25 wt%, and the remainder is bamboo fiber. All other aspects remain the same as in Embodiment 13.

[0108] Example 15

[0109] The difference between this embodiment and Embodiment 13 is that the chitosan fiber content is 25 wt%, the hemp fiber content is 40 wt%, and the remainder is bamboo fiber. All other aspects remain the same as in Embodiment 13.

[0110] The antibacterial performance test results of the fabric samples in Examples 13-15 are shown in Table 5 below.

[0111] Table 5: Antibacterial performance test results of Examples 13-15

[0112]

[0113]

[0114] In Examples 13-15, the proportions and components of the fiber composition were further optimized, resulting in improved antibacterial properties of the optimized fabric. However, when the proportions of hemp fiber and bamboo fiber in the fiber composition exceeded a certain level, the antibacterial properties of the fabric decreased. This may be because the unique porous structure of bamboo fiber, when its proportion is too high, leads to excessive adsorption of antibacterial components, resulting in uneven distribution of the antibacterial components on the fabric and affecting its antibacterial effect.

[0115] Example 16

[0116] The main difference between this embodiment and embodiment 5 is that the fumigation agents used in the fumigation process include artemisia annua, peppermint, juniper and chrysanthemum, while the rest are the same as in embodiment 5.

[0117] Example 17

[0118] The difference between this embodiment and embodiment 5 is that the fabric is dried at a temperature of 85-95°C after fumigation treatment, while the rest is the same as in embodiment 5.

[0119] Example 18

[0120] The main difference between this embodiment and embodiment 5 is that water vapor is used in the fumigation process and no fumigation agent is added; otherwise, they are consistent with embodiment 5.

[0121] The antibacterial performance test results of the fabric samples in Examples 16-18 are shown in Table 6 below.

[0122] Table 6: Antibacterial performance test results of Examples 16-18

[0123]

[0124] Examples 16-18 further adjusted the fumigation process, demonstrating that optimizing the ratio of the fumigating agent during the fumigation process can further enhance the antibacterial properties of the fabric. In Example 18, the antibacterial properties of the fabric treated with steam were significantly lower than in Example 5, indicating that the fumigating agent used in this application significantly improves the antibacterial properties of the fabric.

[0125] Example 19

[0127] S1. The fiber composition is subjected to ultrasonic treatment with an ultrasonic power of 200W and an ultrasonic frequency of 15 seconds every 15 seconds, for a total ultrasonic time of 10 minutes.

[0128] S2. The ultrasonically treated fiber composition is immersed in the antibacterial treatment agent prepared in the preparation example and heated to 45°C for 5 hours.

[0129] S3. After the fiber composition is soaked, it is taken out and dried, and then blended to obtain blended yarn.

[0130] S4. Weave the blended yarn to obtain the fabric.

[0131] S5. Use artemisia annua and mint as fumigation agents, soak them in 6 times the amount of water for 3 hours, then heat them to fumigate the fabric for 6 hours. After the fumigation treatment, dry them at 55-65℃ to obtain anti-mildew and antibacterial fabric.

[0132] Example 20

[0133] A mildew-proof and antibacterial fabric, with the same component ratio as in Example 5, and the specific production process is as follows:

[0134] S1. The fiber composition of bamboo fiber and hemp fiber is impregnated in the antibacterial treatment agent prepared in the preparation example and heated to 45°C for 5 hours.

[0135] S2. After the fiber composition is soaked, it is taken out and dried, and then blended to obtain blended yarn;

[0136] S3. Weave the blended yarn to obtain the fabric.

[0137] S4. The fabric is treated with nitrogen plasma at a power of 200W for 80 seconds.

[0138] S5. Use artemisia annua and mint as fumigation agents, soak them in 6 times the amount of water for 3 hours, and then heat them to fumigate the plasma-treated fabric for 6 hours. After the fumigation treatment, dry it at 55-65℃ to obtain anti-mildew and antibacterial fabric.

[0139] Example 21

[0140] The difference between this embodiment and Embodiment 1 is that no plant extracts are added to the antibacterial treatment agent; otherwise, they are consistent with Embodiment 1.

[0141] Example 22

[0142] The difference between this embodiment and Embodiment 1 is that white bamboo charcoal is not added to the antibacterial treatment agent; otherwise, they are consistent with Embodiment 1.

[0143] The antibacterial performance test results of the fabric samples in Examples 19-22 and Comparative Examples 1-3 are shown in Table 7 below.

[0144] Table 7: Antibacterial performance test results of Examples 19-22

[0145]

[0146] In Examples 19 and 20, the fiber composition and the fabric were subjected to ultrasonic treatment and plasma treatment, respectively. The antibacterial properties of the resulting fabric were also significantly improved. It can be seen that ultrasonic treatment and plasma treatment can improve the adhesion of antibacterial substances to the fabric to a certain extent and enhance the antibacterial effect of the fabric.

[0147] In Examples 21 and 22, the plant extracts and white bamboo charcoal were removed from the antibacterial treatment agent, respectively, resulting in a significant decrease in the antibacterial properties of the corresponding fabrics. This demonstrates that plant extracts and white bamboo charcoal are among the main factors contributing to the good antibacterial properties of the fabrics.

[0148] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
