This material not only effectively reduces the sliding of the device during movement and improves wearing stability, but also enhances the comfort and durability of the device through its unique composite structure. In addition, the material also has good breathability and antibacterial properties, which can meet the user’s needs in different environments.
This article aims to deeply explore the research and development process, technical parameters and performance in practical applications of smart wearable device-friendly inter-cotton composite TPU anti-slip fabrics, and provide reference for researchers and practitioners in related fields. The article will conduct detailed analysis from the aspects of material characteristics, production processes, performance testing, etc., and quote relevant domestic and foreign literature to support the discussion, striving to fully demonstrate the technical advantages and market prospects of this new material.
2. Basic characteristics of inter-cotton composite TPU anti-slip fabric
(I) Material composition and structure
The intercot cotton composite TPU anti-slip cloth is a multi-layer composite material, composed of the intercot cotton fiber layer and the TPU film layer through hot pressing or adhesive processes. Specifically, the intercotch fiber layer provides a soft feel and good breathability, while the TPU film layer imparts high strength, wear resistance and anti-slip properties to the material. The synergistic effect of the two allows the material to have excellent physical and chemical properties while maintaining lightweight.

Whether in dry or humid environments, the equipment can be effectively prevented from slipping, especially suitable for use in sports scenarios. -
Excellent breathability
The presence of the intercotch fiber layer ensures good breathability of the material, so that the wearer will not feel stuffy or uncomfortable during long use. -
Environmental and Sustainability
The material is made of recyclable TPU raw materials and is manufactured through a green production process, which meets the needs of modern consumers for environmentally friendly products. -
Verifiability
In addition to being used in smart wearable devices, this material can also be widely used in household goods, sports equipment and other fields, demonstrating its wide applicability.
3. Production process and process
The production of inter-cotton composite TPU anti-slip fabric involves multiple complex steps, mainly including raw material preparation, composite processing and post-treatment. The following is the detailed production process:
(I) Raw material preparation
-
Selecting cotton fiber
Choose high-quality intercotch fiber to ensure its softness and breathability are in good condition. The fiber length is usually controlled within the range of 30-50mm to ensure uniformity of subsequent processing. -
Preparation of TPU film
The TPU particles were heated to a molten state using an extruder and formed into a film through a mold. The film thickness must be strictly controlled within the design range to ensure the performance consistency of the final product.
(II) Compound processing
-
Hot press composite
The intercotch fiber layer and the TPU film layer were placed in a hot press and combined at specific temperatures (about 180°C) and pressure conditions. This process requires precise control of time to avoid performance degradation due to overheating of the material. -
Surface treatment
The composite material is surface modified to further improve its anti-slip performance. Commonly used treatment methods include laser etching, chemical coating, etc.
(III) Post-processing
-
Crop and mold
According to customer needs, cut the composite material into desired shapes and sizes and trim the edges to ensure a clean appearance. -
Quality Test
Comprehensive quality inspection of the finished products, including key indicators such as thickness, tensile strength, and anti-slip coefficient to ensure that each batch of products meets the standards.
| Production stage | Key Control Points | Target value/range |
|---|---|---|
| Raw Materials | Fiber length,TPU purity | 30-50mm, ≥98% |
| Hot pressing composite | Temperature, pressure, time | 180°C, 5MPa, 10s |

According to the ASTM D2047 standard, the material’s anti-slip coefficient under dry and wet conditions was tested respectively. The results show that the material’s anti-slip coefficient in the dry state reached 0.85, and still maintained above 0.6 in the wet state, which is far higher than the industry average.
(II) Wear resistance test
The durability evaluation of the material is performed using a Taber wear tester. After 50,000 cycles, no obvious wear marks appeared on the surface of the material, proving that it has extremely high wear resistance.
(III) Antibacterial performance test
The antibacterial properties of the material are tested in accordance with JIS Z 2801 standard. The results show that the inhibitory rate of this material on Staphylococcus aureus and E. coli exceeded 99%, indicating that it has good antibacterial effects.
