[0038] Example 2: This example introduces a method for preparing the sole in Example 1, specifically a method for preparing the midsole in Example 1. The midsole is the material that is in direct contact with the sole of the foot or indirectly in contact with the sole through the insole. Its softness, antibacterial effect, and dilution and deodorization effect directly determine the comfort of the entire sole. In order to better improve the comfort of the sole, this example further optimizes the method for preparing the midsole on the basis of Example 1. The method for preparing the midsole comprises the following steps (the following components are calculated by mass):

[0039] S1. Preparation of foam layer:

[0040] 1) Preparation of vinyl triethoxysilane (VTEOS) grafted metallocene polyethylene (mPE): 45 parts of mPE resin, 0.05 parts of initiator and 0.5 parts of silane are added to an extruder, mixed in a molten state, and the grafted polyethylene melt is cut into pellets, i.e., material A, by a pelletizer for standby use. Catalysts, antioxidants, anti-copper agents and other additives are mixed with mPE resin, melt-mixed and granulated by an extruder to obtain catalyst masterbatch material B. After mixing material A and material B evenly, add them to an extruder for melt extrusion, granulation, pelletization, cooling and drying to obtain vinyl triethoxysilane (VTEOS) grafted metallocene polyethylene (mPE), which is standby use;

[0041] 2) Forming a shape memory eco-based EVA / mPE-g-VTEOS foam layer: 55 parts of ethylene-vinyl acetate copolymer (EVA) and metallocene polyethylene (mPE) grafted with vinyl triethoxysilane (VTEOS) were mixed in a mixer at 95° C. for 10 min to obtain a mixture.

[0042] 3) Molding: Pour the mixture into the midsole mold, cool the mold to room temperature through water, trim the edges, and obtain an 8 mm thick foam layer.

[0043] S2. Preparation of fiber layer:

[0044] 1) Preparation of aromatic microcapsule finishing liquid: a certain amount of chitosan and quaternary ammonium salt are dissolved in 1% acetic acid solution, stirred and filtered to obtain 8 mg / mL chitosan / quaternary ammonium salt mixed solution, the mass ratio of the two is controlled to be 5:1, and the pH value is adjusted to 4.0 with 0.05 g / mL sodium hydroxide solution for standby use; 5 mg / mL sodium tripolyphosphate solution and 25 mg / mL catechin aqueous solution are mixed and dripped into the chitosan / quaternary ammonium salt mixed solution and stirred for ion crosslinking. After the crosslinking reaction is completed, centrifuge, wash and dry to obtain aromatic microcapsule finishing liquid;

[0045] 2) Mixed fiber: 5 parts of flax fiber, 8 parts of bamboo fiber and 2 parts of chitosan fiber are blended into yarn through a blending process, the yarn is added into a bleaching solution for bleaching, and then added into a dye for dyeing;

[0046] 3) Padding: The yarn after oxygen bleaching and dyeing is subjected to padding finishing, and the yarn is added to the aromatic microcapsule finishing liquid, impregnated, dehydrated, and dried to obtain the aromatic microcapsule blended antibacterial fiber, and the blended fiber is cut into the shape of the midsole to obtain a 2 mm fiber layer.

[0047] S3. Composite molding: glue is added into the midsole mold to composite the fiber layer and the foam layer into one body to form the midsole, wherein the fiber layer is placed above the foam layer.

[0048] EVA and metallocene polyethylene (mPE) grafted with vinyltriethoxysilane (VTEOS) are melt-blended to form a shape memory eco-based EVA / mPE-g-VTEOS mixture. The interaction between the silane groups on mPE and the vinyl acetate groups on EVA improves the tensile strength and Young's modulus of the EVA / mPE-g-VTEOS blend. The addition of VTEOS improves the thermal stability and shape fixity of the EVA / mPE-g-VTEOS blend, and the shape memory index (SMI) and recovery rate are significantly improved. The composite material can also be recycled, reprocessed and reused, and has good environmental friendliness.

[0049] The composite material is used as the foam layer of the midsole, which has good shock-absorbing properties and can effectively absorb the impact when walking or running, reducing the pressure on the feet and joints. At the same time, its excellent shape memory function allows the midsole to adjust according to the shape and pressure points of the foot to provide personalized support. It slowly rebounds after being compressed, which can effectively disperse the pressure points of the foot and reduce fatigue. At the same time, it has a long service life, is not easy to deform or compress, and can maintain comfort and support for a long time.

[0050] Catechins have excellent antibacterial and deodorizing functions. The antibacterial and deodorizing effects are achieved through a variety of mechanisms. Catechins can insert into the cell membrane of bacteria and destroy its integrity. This destruction will increase the permeability of the cell membrane, causing the cell contents to leak, leading to bacterial death. Catechins can inhibit the activity of certain key enzymes in bacteria, which play an important role in bacterial metabolism and growth. For example, catechins have an inhibitory effect on bacterial lipase and protease, which affects the growth and reproduction of bacteria. Thereby reducing the generation of odor. Catechins interfere with the protein synthesis process by binding to the ribosomes of bacteria, and this interference inhibits the growth and reproduction of bacteria. Catechins can inhibit the formation of biofilms on the surface of bacteria. Biofilms are structures where bacteria gather and form a protective barrier. By preventing the formation of biofilms, catechins reduce the adhesion and drug resistance of bacteria. Catechins have strong antioxidant capacity and can neutralize free radicals in the body. These free radicals are often involved in the formation of odorous substances. Through antioxidant effects, catechins reduce the generation of odorous substances. In conclusion, the addition of catechins improves the deodorizing effect of men's shoes.

[0051] Microcapsule technology can better maintain and release the antioxidant effect of catechins, achieve sustained release of catechins, and maintain their long-term activity. CS-EGCG microcapsules were successfully prepared with chitosan (CS) as the shell structure, catechins (EGCG) as the core structure, and sodium tripolyphosphate (TPP) as the cross-linking agent. STAC-CS-EGCG microcapsules were successfully prepared by introducing quaternary ammonium salt STAC with more prominent cationic properties to partially replace protonated chitosan, achieving rapid blockade of catechins and giving the shell structure excellent antibacterial function.

[0052] Flax fiber, bamboo fiber, and chitosan fiber are all natural fibers. Natural fibers are widely available and renewable, which helps reduce dependence on limited resources. Among them, flax fiber is the only bundled plant fiber among natural fibers. It has a natural spindle-shaped structure and unique pectin-like beveled pores, which gives it excellent moisture absorption, air permeability, and corrosion resistance, and has the characteristics of high strength and high modulus.

[0053] Bamboo fiber has the best moisture absorption and perspiration among all fiber categories, which is inseparable from its own structure. The interior of bamboo fiber is an annular network structure, and the cross section is full of elliptical gaps. It is highly hollow and can quickly absorb moisture secreted by sweat glands and destroy the living environment of bacteria and microorganisms. At the same time, bamboo fiber contains natural antibacterial substances "bamboo quinone", which can effectively inhibit the formation of cell membranes and thus play an effective antibacterial role. Bamboo fiber has good air permeability, instant water absorption, wear resistance, natural antibacterial and antibacterial properties, and environmental protection characteristics.

[0054] Chitosan has a wide spectrum of antibacterial properties. The positively charged amino group is the key to interacting with bacterial cell membranes. The amino group can destroy the interaction between lipids and reduce the stability of bacterial membrane structures. The structure of chitosan is a linear molecular chain, and the main chain contains a six-membered ring structure, which has a certain rigidity and is suitable for spinning to prepare fibers.

[0055] Therefore, the advantages of various fibers can be fully utilized to provide more comprehensive performance for the sole. Flax fiber improves the overall strength and durability of the sole, bamboo fiber uses its moisture absorption and breathability to help absorb sweat and keep the feet dry while increasing comfort, and chitosan fiber is used to provide support and structural stability, while considering its biodegradability and environmental protection properties.
