Description

Technical Field

[0001] The invention relates to the field of shoe product manufacturing, in particular to a method for manufacturing waterproof and breathable military shoe fabric. Background Art

[0002] In military and special operations environments, the performance requirements for shoes are very high, including wear resistance, waterproofness, breathability, impact resistance, and the ability to adapt to various extreme environments. At present, the fabric manufacturing process of military shoes mainly includes the following aspects: Material selection: Traditional military shoe fabrics usually use high-performance textile materials such as aramid fiber, ultra-high molecular weight polyethylene (UHMWPE) and polyamide fiber. These materials have high strength and wear resistance and can meet basic protection needs.

[0003] In order to improve waterproof performance, commonly used waterproof materials include polyurethane (PU) coating, polytetrafluoroethylene (PTFE) film and waterproof breathable membrane (such as GORE-TEX). These materials can effectively block water penetration, but usually sacrifice a certain degree of breathability.

[0004] Coating treatment: In order to enhance the waterproof performance of fabrics, a waterproof coating is usually applied to the surface of textile materials. Common coating materials include polyurethane (PU) and silicone resin. These coating materials can form a waterproof barrier, but often reduce the breathability of the fabric.

[0005] To increase abrasion and tear resistance, the fabric is sometimes coated with an abrasion-resistant coating, such as polyurethane or polyester.

[0006] Finishing process: Fabric finishing includes pretreatment, coating and finishing. Pretreatment usually includes washing, drying and finishing to ensure that the surface of the material is clean and free of impurities.

[0007] After coating, the fabric is usually shaped, ironed and smoothed to ensure it lies flat and wrinkle-free.

[0008] Post-finishing includes antibacterial treatment, antistatic treatment and flame retardant treatment to improve the functionality of the fabric.

[0009] Performance Test: In order to ensure the quality and performance of the fabric, a series of performance tests are usually carried out, including waterproof test, breathability test, abrasion resistance test and antibacterial test. Commonly used test standards include AATCC 81 (waterproof test), ASTMD737 (breathability test), Martindale abrasion tester (abrasion resistance test) and AATCC 100 (antibacterial test).

[0010] Problems Although the existing military shoe fabric manufacturing process can meet the basic performance requirements to a certain extent, it still has the following shortcomings: It is difficult to achieve both waterproofness and breathability: Traditional waterproof materials and coatings often sacrifice breathability, causing the wearer to feel stuffy and uncomfortable in humid or rainy environments.

[0011] Insufficient wear resistance and durability: In extreme environments, such as deserts, jungles or battlefields, traditional textile materials are easily worn out, affecting the service life of the shoes.

[0012] Poor antibacterial performance: Under long-term wear and harsh environment, traditional shoe lining materials are prone to breed bacteria, affecting the health of the wearer. Summary of the invention
