Description

Technical Field

[0001] The invention belongs to the technical field of fabric weaving, and relates to an antibacterial blended fabric and a weaving process. Background Art

[0002] Among many fiber materials, spandex is favored for its excellent elasticity and comfort, which can provide excellent fit and freedom of movement, while nylon has the characteristics of high strength, good wear resistance and strong wrinkle resistance. The blended production of the two fibers has become an ideal choice for sportswear and functional fabrics. Among them, the application of antibacterial fabrics has also been widely promoted.

[0003] At present, antibacterial fabrics usually achieve their antibacterial purpose by adding antibacterial agents and surface treatment. However, some antibacterial fabrics have weak antibacterial effects. Although some antibacterial fabrics have strong antibacterial effects, the antibacterial agents used are easy to irritate the skin. In addition, these antibacterial fabrics are not durable enough in terms of antibacterial properties. After repeated washing, the antibacterial agents fall off and the antibacterial performance is weakened. These problems need to be overcome. Summary of the Invention

[0004] The purpose of the present invention is to provide an antibacterial blended fabric and a weaving process. The present invention uses modified nano-antibacterial capsules, antibacterial agents and other components, and weaves the antibacterial blended fabric through a specific process. The prepared antibacterial blended fabric has the characteristics of being mild and non-irritating. The antibacterial components can be tightly adhered to the surface of the fabric, ensuring that they are not easily fallen off during use and washing, thereby achieving a long-lasting antibacterial effect.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0010] Furthermore, the weft knitting in step 1 uses nylon as the warp and spandex as the weft, sets the loom tension to 0.5-1N, the speed to 105-135m / min, and weaves at a weaving density of 10 weft yarns and 10 warp yarns per inch.

[0011] Furthermore, the cleaning in step 1 is performed by soaking in Tween-20 with a concentration of 1-2 wt% for 15-30 minutes, and then rinsing with deionized water.

[0012] Furthermore, the desizing in step 1 is performed by soaking in a NaOH solution with a concentration of 2-5 wt% for 30-60 min, and then rinsing with deionized water.

[0013] Furthermore, the refining in step 1 is performed by soaking in Tween-80 with a concentration of 1-3 wt% for 30-60 minutes, and then rinsing with deionized water and drying naturally.

[0014] Furthermore, the raw materials of the antibacterial finishing liquid in step 2 include, by mass percentage, 17-23% of modified nano antibacterial capsules, 20-30% of antibacterial agent, 0.5-1.5% of nonionic surfactant and the balance of deionized water.

[0018] Step X2: mixing the antibacterial agent and the shell solution in a mass ratio of 3.5-4.1:1, and emulsifying the mixture using an ultrasonic emulsification device to obtain an emulsion;

[0019] Step X3, spray drying the emulsion until the particle size reaches 100-150 nm to obtain nano antibacterial capsules;

[0020] Step X4: Mix the nano-antibacterial capsules and the modified PVA solution in a ratio of 1:2.2-3 g / mL, soak for 30-40 minutes, take out, rinse with deionized water, and dry naturally to obtain the modified nano-antibacterial capsules.

[0021] Furthermore, the nonionic surfactant in step X1 is Tween-60.

[0022] Furthermore, the parameters of the ultrasonic emulsification equipment in step X2 are: emulsification frequency is 15-25kHz, and emulsification time is 8-12min.

[0023] Furthermore, the spray drying parameters in step X3 are: air inlet temperature of 100-102°C, and air outlet temperature of 60-62°C.

[0024] Furthermore, the raw materials of the modified PVA solution in step X4 include, by mass percentage, 10-20% of modified PVA and the balance of deionized water.

[0025] Furthermore, the antibacterial agents are obtained by mixing stemonae essential oil, cyperus rotundus essential oil, wormwood essential oil, honeysuckle essential oil and non-ionic surfactant in a mass ratio of 0.3-0.4:0.41-0.49:0.55-0.65:0.36-0.4:0.05-0.09.

[0026] Furthermore, the nonionic surfactant is Tween-60.

[0027] Furthermore, the preparation method of the Stemona essential oil and the Cynanchum wilfordii essential oil comprises the following steps:

[0028] The stemonae root is washed, dried, cut into small sections, mixed with 53-57% ethanol solution at a ratio of 1:2-3 g / mL, and extracted at 65-75° C. for 1-2 hours. The mixture is then cooled to 45-55° C., kept at the same temperature and soaked for 48-50 hours, and filtered through a 300-mesh filter cloth. The obtained stemonae extract is evaporated at 40-50° C. until the product is entirely oily, thereby obtaining stemonae essential oil. The cyperus rotundus is washed, dried, cut into small sections, mixed with 68-72% ethanol solution at a ratio of 1:2-3 g / mL, and soaked for 48-52 hours, and filtered through a 300-mesh filter cloth. The obtained cyperus rotundus extract is evaporated at 40-50° C. until the product is entirely oily, thereby obtaining cyperus rotundus essential oil.

[0030] Beneficial effects of the present invention:

[0031] (1) The modified nano antibacterial capsules prepared by the present invention use polylactic acid as the shell material and wrap the antibacterial agent obtained by compounding Stemona radix essential oil, Camphora vine essential oil, Artemisia argyi essential oil, etc., which is mild and non-irritating to the skin. Its small particle size and modified treatment enable it to be tightly attached to the surface of the fabric, making it difficult for the antibacterial component to fall off during use and washing, and continuously exerting its antibacterial effect.

[0032] (2) The antibacterial agent of the present invention is obtained by compounding Stemona essential oil, Camphor Tree essential oil, Artemisia argyi essential oil, etc., wherein Stemona essential oil is rich in volatile components with antibacterial effects such as geraniol and citronellol, Camphor Tree essential oil contains flavonoids, phenolic compounds and other active ingredients that can inhibit the growth of microorganisms, Artemisia argyi essential oil contains volatile oils, ketones, terpenes and other antibacterial components that can effectively inhibit the growth and reproduction of various bacteria, and chlorogenic acid and flavonoids in honeysuckle essential oil also have good antibacterial effects. Various plant essential oils work synergistically to interfere with the protein synthesis and Cell metabolism, destroying the cell membrane structure of bacteria, thereby affecting the growth and reproduction of bacteria, and achieving a broad-spectrum antibacterial effect; in addition, the essential oils extracted from plants are less irritating to the human body, and their own aromatic smell can also reduce the odor caused by bacterial reproduction, thereby improving wearing comfort; on this basis, the present invention also uses an antibacterial finishing liquid containing an antibacterial agent to soak the fabric, so that the antibacterial component is further evenly attached to the surface and interior of the fabric fiber, avoiding the problem of excessive differences in local antibacterial effects, thereby ensuring the consistency and stability of the antibacterial performance of the entire fabric.

[0033] (3) The present invention uses modified nano-antibacterial capsules, antibacterial agents and other components to weave antibacterial blended fabrics through a specific process. The prepared antibacterial blended fabrics have the characteristics of being mild and non-irritating. The antibacterial components can be tightly attached to the surface of the fabric, ensuring that they are not easy to fall off during use and washing, thereby achieving a long-lasting antibacterial effect.
