Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to an antibacterial fabric, its preparation method, and clothing containing rare earth magnetic particles. Background Technology

[0002] Throughout history, people's demands for clothing have never been limited to basic clothing needs. For the general public, clothing not only needs to meet the basic requirements of clothing, but also needs to meet other requirements such as decoration and practicality. Nowadays, people prefer clothing that has daily preventative and health care functions.

[0003] Clothing fabrics are mostly composed of fibers, and the porous structure of fibers makes them ideal for microorganisms to attach to and parasitize. When a large number of microorganisms multiply and parasitize on fabrics, they can harm human health. Therefore, it is necessary to improve the antibacterial properties of fabrics to reduce the harm caused by microorganisms during daily wear and achieve the purpose of prevention and health care.

[0004] Traditional antibacterial fabrics achieve their antibacterial properties by adding antibacterial finishing agents during fabric production. However, traditional antibacterial fabrics have poor durability. After repeated washing, the antibacterial finishing agents, which are not firmly bonded to the fabric, will detach and peel off, resulting in a significant decrease or even loss of the fabric's antibacterial properties, severely impacting its durability. Therefore, the durability of antibacterial fabrics needs further improvement. Summary of the Invention

[0005] To improve the durability of antibacterial fabrics, this application provides an antibacterial fabric, a method for preparing the same, and clothing containing rare earth magnetic particles. The method for preparing the antibacterial fabric disclosed in this application can effectively improve the fabric's durability and has significant application value for preparing clothing with excellent antibacterial properties.

[0006] Firstly, the method for preparing an antibacterial fabric provided in this application adopts the following technical solution:

[0007] A method for preparing an antibacterial fabric includes the following steps:

[0008] Step 1, Fiber preparation:

[0009] Step 1-1, Preparation of antibacterial fiber: Based on the mass fraction of composite spinning solution, mix 100 parts viscose spinning solution, 3-6 parts bamboo charcoal powder, 10-12 parts mixed extract, and 1-3 parts dispersant and stir evenly. After standing to defoam, prepare antibacterial fiber by wet spinning process at 70-80℃.

[0010] Steps 1-2, Preparation of high-elasticity fibers: TPU is melted and then extruded to obtain high-elasticity fibers;

[0011] Step 2, spinning: The antibacterial fiber and high elastic fiber obtained in step 1 are blended at a mass ratio of (20-26):(74-80) to obtain yarn;

[0012] Step 3, weaving the fabric: the yarn obtained in step 2 is woven into a fabric blank, washed and dried to obtain an antibacterial fabric.

[0013] The preparation method of the mixed extract is as follows:

[0014] s1: Wash fresh Solomon's Seal, mint leaves, and cassava, chop them, mix them, and juice them. The volume ratio of Solomon's Seal, mint leaves, cassava, and water is 1:(0.5-0.7):(0.4-0.6):(2-3) to obtain mixed juice.

[0015] s2: Take the mixed juice obtained in step s1, add Lactobacillus fermentum, Lactobacillus plantarum, Pseudomonas fluorescens, and Streptomyces flavus, and ferment in a sealed container at 25-28℃ for 1.5-2 days to obtain the fermented mixed juice; wherein, the volume ratio of the mixed juice, Lactobacillus fermentum, Lactobacillus plantarum, Pseudomonas fluorescens, and Streptomyces flavus is 100:(1-2):(1-2):(1-2):(1-2);

[0016] s3: After filtering the mixed juice, the filtrate is obtained. After pasteurizing the filtrate, the mixed extract is obtained.

[0017] In the above technical solution, this application significantly improves the antibacterial properties of the fiber by adding bamboo charcoal powder and mixed extract during the preparation of antibacterial fiber, resulting in antibacterial fiber with good antibacterial properties. Such antibacterial fiber has good durability and retains good antibacterial properties even after multiple washes.

[0018] This application describes the production of antibacterial fabric by blending antibacterial fibers and high-elastic fibers. The antibacterial fibers endow the antibacterial fabric with good antibacterial properties, while the high-elastic fibers endow it with good resilience. Clothing made from such antibacterial fabric not only has good antibacterial properties and durability, but also better conforms to the curves of the human body, improving the consumer's wearing experience.

[0019] This application significantly improves the antibacterial properties of the mixed extract by mixing Solomon's seal, peppermint leaves, and cassava, and then fermenting it with Lactobacillus fermentum, Lactobacillus plantarum, Pseudomonas fluorescens, and Streptomyces flavus. In addition, this application found in the study that the mixed extract prepared by this method has good compatibility with viscose spinning solution and can be well dispersed in viscose spinning solution, so that the antibacterial fiber has stable antibacterial properties.

[0020] Preferably, the volume ratio of Lactobacillus fermentum, Lactobacillus plantarum, Pseudomonas fluorescens, and Streptomyces flavus is 2:1:1:1.

[0021] In the above technical solution, when the volume ratio of *Lactobacillus fermentum*, *Lactobacillus plantarum*, *Pseudomonas fluorescens*, and *Streptomyces flavus* is 2:1:1:1, this ratio allows the various strains to promote each other during fermentation, improving fermentation efficiency. Simultaneously, this ratio can also produce more peptides and other substances that inhibit the growth of harmful strains, significantly improving the antibacterial properties of the antibacterial fiber.

[0022] Preferably, steps 1-2 are as follows:

[0023] Based on the mass fractions of the raw materials for high-elastic fibers, 40-60 parts of polyester-type TPU, 20-25 parts of polyether-type TPU, 5-7 parts of nano-titanium dioxide, 5-7 parts of nano-zinc oxide, 1-2 parts of dimethyl hydroxymethyl phosphite, 1-2 parts of glycerol polyoxyethylene ether, and 0.8-1.2 parts of glycyl sarcosine are mixed evenly and then extruded to obtain high-elastic fibers.

[0024] In the above technical solution, this application further improves the antibacterial properties of high-elastic fibers by adding nano-titanium dioxide and nano-zinc oxide during the preparation of high-elastic fibers, and further improves the antibacterial properties of antibacterial fabrics. This application further adds dimethyl hydroxymethyl phosphite, glycerol polyoxyethylene ether, and glycyl sarcosine, which significantly improves the dispersibility of nano-titanium dioxide and nano-zinc oxide in TPU, and further improves the antibacterial stability of high-elastic fibers.

[0025] Preferably, the mass ratio of dimethyl hydroxymethyl phosphite, glycerol polyoxyethylene ether, and glycyl sarcosine is 1:2:0.8.

[0026] In the above technical solution, this application further optimizes the ratio of high-elastic fibers by controlling the mass ratio of dimethyl hydroxyphosphite, glycerol polyoxyethylene ether, and glycyl sarcosine to 1:2:0.8, thereby improving the antibacterial properties and antibacterial stability of the high-elastic fibers.

[0027] Preferably, the dispersing agent in step 1-1 is carboxymethyl cellulose.

[0028] In the above technical solution, this application further improves the dispersibility of bamboo charcoal powder in viscose spinning solution by adding carboxymethyl cellulose, thereby obtaining antibacterial fibers with better antibacterial stability.

[0029] Preferably, the viscose spinning solution in step 1-1 contains 8.2% to 8.9% methyl cellulose.

[0030] In the above technical solution, by limiting the content of methyl methacrylate to 8.2% to 8.9%, the stability and spinnability of the viscose spinning solution can be ensured, and it can better cooperate with other substances in the antibacterial fiber, thereby obtaining antibacterial fiber with excellent quality.

[0031] Secondly, the antibacterial fabric provided in this application adopts the following technical solution:

[0032] An antibacterial fabric, wherein the antibacterial fabric is prepared by the method for preparing antibacterial fabric described in the first aspect.

[0033] In the above technical solution, the antibacterial fabric prepared by the method of the first aspect of the application not only has good antibacterial properties and durability, and increases the daily prevention and health care function of clothing, but also the clothing made of such fabric can better fit the curves of the human body during the wearing process, and has a good wearing experience.

[0034] Thirdly, the clothing containing rare earth magnetic particles provided in this application adopts the following technical solution:

[0035] A garment with rare earth magnetic particles, wherein the garment is made by embedding high-energy rare earth magnetic particles into the garment, and the garment is made of an antibacterial fabric as described in the second aspect.

[0036] In the above-mentioned technical solution, this application embeds high-energy rare-earth magnetic particles into clothing, thereby giving the clothing better health benefits and comfort. Simultaneously, using antibacterial fabric to prepare the clothing allows it to better conform to the body's curves and provides better antibacterial properties and durability.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. This application obtains a mixed extract with good antibacterial properties by juicing a mixture of Solomon's seal, peppermint leaves, and cassava, followed by fermentation with Lactobacillus fermentum, Lactobacillus plantarum, Pseudomonas fluorescens, and Streptomyces flavus. At the same time, this mixed extract has good compatibility with viscose spinning solution and can be well dispersed in viscose spinning solution, so that the antibacterial fiber has good antibacterial properties and antibacterial stability.

[0039] 2. This application significantly improves the dispersibility of nano-titanium dioxide and nano-zinc oxide in high-elastic fibers by adding dimethyl hydroxymethyl phosphite, glycerol polyoxyethylene ether, and glycyl sarcosine during the preparation of high-elastic fibers, thereby further improving the antibacterial properties and antibacterial stability of high-elastic fibers.

[0040] 3. This application endows antibacterial fabrics with good antibacterial properties through antibacterial fibers, and with good resilience through high-elastic fibers. Antibacterial fabrics are obtained by blending antibacterial fibers and high-elastic fibers, thereby improving the consumer's wearing experience. Attached Figure Description

[0156] Application Example 1

[0157] A type of clothing containing rare earth magnetic particles, see reference. Figure 1 and Figure 2 Clothing with rare earth magnetic particles is made by embedding high-energy rare earth magnetic particles into clothing, wherein the clothing is made using the antibacterial fabric of Examples 1-8.

[0158] Experimental Example 1

[0159] The antibacterial rate of the antibacterial fabrics in the above examples and comparative examples was tested according to FZ / T 73023—2006 "Antibacterial Knitted Fabrics" after 0 washes and 20 washes. Ten pieces of antibacterial fabric from different areas of each experimental group were cut for parallel experiments, and the average value of the results was taken.

[0160] According to the test results, the antibacterial fabrics of Examples 1-8 of this application have an antibacterial rate of AAA grade against Staphylococcus aureus, Escherichia coli and Candida albicans. The specific test results are shown in Table 1.

[0161] Experiment Example 2

[0162] The tensile elastic recovery rate of the antibacterial fabrics in the above examples and comparative examples was tested according to FZ / T 70006-2004 "Test Method for Tensile Elastic Recovery Rate of Knitted Fabrics". The test results are shown in Table 1.

[0163] Table 1:

[0164]

[0165]

[0166] Based on the analysis of Examples 1-9 and Comparative Examples 1-5, it can be concluded that Examples 1-9 have good antibacterial properties, antibacterial stability, and durability, while Examples 1-8 have good elasticity.

[0167] Specifically, based on the analysis of Example 1 and Comparative Example 1, the difference between Comparative Example 1 and Example 1 is that no peppermint leaves were added in Comparative Example 1, while Example 1 has better antibacterial properties. Therefore, it can be concluded that only by adding peppermint leaves during the preparation of the mixed extract can the antibacterial properties of the mixed extract be better activated, promoting better symbiosis of Lactobacillus fermentum, Lactobacillus plantarum, Pseudomonas fluorescens, and Streptomyces flavus, and producing more antibacterial substances.

[0168] Specifically, based on the analysis of Example 1 and Comparative Examples 2-5, the difference between Comparative Examples 2-5 and Example 1 is that Comparative Examples 2-5 did not contain *Lactobacillus fermentum*, *Lactobacillus plantarum*, *Pseudomonas fluorescens*, or *Streptomyces flavus*, respectively. Example 1 exhibits better antibacterial properties. Therefore, it can be concluded that only a combination of *Lactobacillus fermentum*, *Lactobacillus plantarum*, *Pseudomonas fluorescens*, and *Streptomyces flavus* can enable various strains to promote each other during fermentation and produce more peptides and other substances that inhibit the growth of harmful strains, thus significantly improving the antibacterial properties of the antibacterial fiber.

[0169] Specifically, based on the analysis of Examples 1 and 4-6, the difference between Examples 4-6 and Example 1 is that Examples 4-6 did not contain dimethyl hydroxymethyl phosphite, glycerol polyoxyethylene ether, or glycyl sarcosine. The antibacterial properties and elasticity of Examples 4-6 are somewhat inferior to those of Example 1. From this analysis, it can be concluded that the combined effect of dimethyl hydroxymethyl phosphite, glycerol polyoxyethylene ether, and glycyl sarcosine can significantly improve the dispersibility of nano-titanium dioxide and nano-zinc oxide in high-elastic fibers, thereby further improving the antibacterial properties and elasticity of high-elastic fibers and preventing the accumulation of nano-titanium dioxide and nano-zinc oxide in high-elastic fibers, which would lead to a decrease in the elasticity of some fiber segments.

[0170] Specifically, based on the analysis of Examples 1 and 7-9, Example 7 did not add nano-titanium dioxide and nano-zinc oxide, Example 8 only added TPU, and Example 9 did not add dimethyl hydroxymethyl phosphite, glycerol polyoxyethylene ether, or glycyl sarcosine. Example 1 has better antibacterial properties, while Example 7 has slightly lower antibacterial properties. At the same time, Example 7 has good elasticity. Therefore, it can be concluded that nano-titanium dioxide and nano-zinc oxide can further improve the antibacterial properties of high-elastic fibers, while the addition of dimethyl hydroxymethyl phosphite, glycerol polyoxyethylene ether, and glycyl sarcosine also has a certain effect on improving the antibacterial properties and elasticity of high-elastic fibers.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
