[0013] I. Materials The method used in the present application is a conventional method known to those skilled in the art, and the reagents and other materials used are commercially available products unless otherwise specified.

[0014] In the present application, silkworm excrement, volcanic rock particles, natural wood ash, and soapberry extract are all ground to a particle size of 1 nm using a nano-grinding machine.

[0015] II. Method 2.1 Effect of wear-resistant fibers on the performance of antibacterial wear-resistant textile fabric (1) The preparation method of the antibacterial wear-resistant textile fabric is as follows: Take bamboo charcoal ash, wormwood charcoal ash, lavender charcoal ash, and maidenhair charcoal ash and heat them at 70°C. Before heating, add glycerol dropwise, and then precipitate for 26 hours. Take out the precipitate, dry it, and grind it to obtain natural wood ash. Take 45-day-old soapberry fruits, remove the seeds, and break the flesh to obtain fruit pulp. Add citric acid to the fruit pulp, dry it at 70°C, and crush it to obtain soapberry extract. Mix silkworm excrement and volcanic rock particles to obtain mixed particles. Add rosin to a container containing bio-based nylon 66 particles, heat to 280°C, and stir until fully mixed to obtain liquid A. Heat polytetrafluoroethylene to melt, add natural wood ash and soapberry extract, and stir until fully mixed to obtain liquid B. Use a spinning device to spin liquid A and liquid B separately to obtain antibacterial fibers and wear-resistant fibers (the cross-sectional radius of the wear-resistant fibers is 0.2 nm, and the cross-sectional radius of the antibacterial fibers is 0.6 nm). Use a textile machine to spin the antibacterial fibers and wear-resistant fibers into antibacterial wear-resistant yarn, and then use a weaving process to weave the antibacterial wear-resistant yarn into antibacterial wear-resistant fabric.

[0016] The preparation raw materials of the antibacterial fibers include 32 parts of natural wood ash, 12 parts of soapberry extract, and 65 parts of polytetrafluoroethylene particles. The preparation raw materials of the natural wood ash include 12 parts of bamboo charcoal ash, 10 parts of wormwood charcoal ash, 2 parts of lavender charcoal ash, 18 parts of maidenhair charcoal ash, and 3 parts of glycerol.

[0017] The raw material composition of the wear-resistant fibers is shown in the following table: ; Note: "-" means not added (2) The performance of the above antibacterial wear-resistant textile fabric samples is tested using the following test methods ① The fabric samples prepared by the method of Example 1 and Comparative Examples 1-3 were respectively cut into 50cm x 50cm size, and the tensile properties of the samples prepared by the method of Example 1 and Comparative Examples 1-3 were respectively detected according to GB / T 3923.2-2013 "Textiles-Determination of tensile strength of fabrics-Part 2: Grab method".

[0019] The results are shown in the following table: ; From the above table, it can be seen that the tensile strength performance, elongation at break performance and abrasion resistance times of the fabric sample prepared by the method of Example 1 are better than those of Comparative Examples 1-3.

Comparing Example 1 with Comparative Example 2 alone, it can be found that the difference between Example 1 and Comparative Example 2 is that Comparative Example 2 does not add rosin, resulting in that the tensile strength performance, elongation at break performance and abrasion resistance times of Comparative Example 2 are not as good as those of Example 1. Comparing Example 1 with Comparative Example 3 alone, it can be found that the difference between Example 1 and Comparative Example 3 is that Comparative Example 3 does not add silkworm ash and rosin, resulting in that the tensile strength performance, elongation at break performance and abrasion resistance times of Comparative Example 3 are not as good as those of Example 1, and the data of Comparative Example 3 are worse than those of Comparative Examples 1-2. In summary, the addition of silkworm ash and rosin can increase the tensile strength performance, elongation at break performance and abrasion resistance times of the fabric sample, making the fabric more solid and wear-resistant.
