1. Overview of the cotton composite TPU anti-slip fabric
Middle cotton composite TPU anti-slip fabric is an innovative functional textile material that combines thermoplastic polyurethane (TPU) films with meta-aramid fibers through advanced composite technology to form multi-layers with excellent performance Structural material. With its unique physical and chemical properties, this material has shown significant application advantages in the field of outdoor equipment. According to the standards defined by the American Association of Materials and Testing (ASTM), intercotch composite TPU anti-slip fabric belongs to the category of high-performance engineering textiles, and its core feature is that it has both high strength, high temperature resistance, flame retardancy and excellent anti-slip properties.
In terms of material composition, the composite fabric adopts a three-layer structural design: the surface layer is a specially treated TPU film, the middle layer is a meta-aramid fiber braided layer, and the bottom layer is a reinforced fabric substrate. This sandwich-style structural design not only ensures the overall strength of the material, but also gives it excellent wear resistance and tear resistance. According to research data from the Textile Institute of the UK, the tensile strength of intercotch composite TPU anti-slip fabric can reach 350-450N/5cm, far exceeding the performance indicators of traditional anti-slip materials.
As a new generation of outdoor equipment material, intercotton composite TPU anti-slip cloth performs excellently in multiple key performance indicators. Its static friction coefficient reaches between 0.7-0.9, and the dynamic friction coefficient remains around 0.6. This numerical range ensures that the material can provide a reliable anti-slip effect under various environmental conditions. In addition, the material has good weather resistance and can maintain stable physical properties in the temperature range of -40°C to 120°C, which makes it particularly suitable for outdoor equipment manufacturing in extreme climate conditions.
