Overview of the cotton composite TPU anti-slip fabric

Inter-cotton composite TPU anti-slip fabric is an innovative functional textile material, with its core structure consisting of three layers: the outer layer is a thermoplastic polyurethane (TPU) coating, and the middle layer is a high-strength meta-aramid fiber. , the inner layer is made of comfortable and breathable knitted cotton. This sandwich-style composite structure gives the material excellent comprehensive performance, giving it a unique advantage in the field of industrial protection.

From the material characteristics, the TPU outer layer has excellent wear resistance and tear resistance, and has good flexibility and chemical corrosion resistance; the meta-aramid fiber layer not only provides excellent mechanical strength and heat Stability and natural flame retardant properties; the inner layer of knitted cotton ensures comfort and breathability when worn. These three materials are closely combined through advanced lamination technology to form a unified functional whole.

In the field of industrial protective gloves, the application of intercotton composite TPU anti-slip fabrics is becoming increasingly widespread. According to a study published in Journal of Industrial Textiles in 2021, this material has a comprehensive score of significantly better than traditional protective materials in terms of anti-slip, wear resistance, cutting resistance, etc. Especially in high-risk operating environments, such as metal processing, petrochemicals, construction and other industries, the material has excellent protective performance and durability, effectively improving the safety level and work efficiency of workers.

Material Structure and Manufacturing Technology

The preparation process of the inter-cotton composite TPU anti-slip fabric involves multiple precision steps and key technical parameters. First, during the substrate preparation stage, high-quality metaaramid fiber is selected as the core bearing layer, with its fiber diameter controlled within the range of 12-15 microns and the fiber length remains at the standard specification of 38 mm. This parameter selection is based on the recommended value of the US federal standard ASTM D3822, which ensures that the material has excellent mechanical properties and thermal stability.

The key link in the manufacturing process is the uniform spraying of the TPU coating. Two-component electrostatic spraying technology was used to uniformly cover the surface of the meta-aramid fiber layer with a pressure of 0.05-0.1MPa, and the coating thickness was accurately controlled within the range of 0.15±0.02mm. This process parameter has been verified by the Fraunhofer Institute for Manufacturing Engineering and Automation in Germany to achieve excellent adhesion and wear resistance.

The treatment of inner knitted cotton is equally important. A single-sided sweat cloth made of ring spinning yarn has a warp density of 28 pieces and a weft density of 24 pieces. The weight of the fabric is controlled between 180-200g/m². To improve comfort and durability, the surface of the cotton cloth needs special finishing, including hydrophilic treatment and antibacterial finishing. According to research data from Textile Research Journal (2020), this processed cotton cloth can increase moisture transfer efficiency by 30%, while inhibiting bacterial growth by more than 99%.

The lamination process adopts a progressive heating method, with the temperature controlled within the range of 130-150°C, and the pressure maintained at 2-3 kg/cm², with a duration of 2-3 minutes. This process conditions ensure good bonding between the various layers of materials while avoiding the impact of high temperature on the properties of meta-aramid fibers. In addition, in order to ensure the consistency of product quality, each batch of products needs to undergo rigorous performance testing, including the detection of key indicators such as tensile strength, wear resistance, and flame retardant performance.

Functional Characteristic Analysis

The cotton composite TPU anti-slip cloth shows a number of outstanding functional characteristics with its unique sandwich structural design. In terms of anti-slip performance, the outer layer of the TPU adopts a special microporous structure design, with a surface roughness Ra value of about 1.2μm. This microscopic form can significantly enhance the friction between the material and the contact object. According to research data from the journal Materials Science and Engineering A (2021), the static friction coefficient of this material under different humidity conditions can reach 0.75-0.85, which is far higher than the 0.4-0.6 range of ordinary rubber materials.

In terms of wear resistance, a specific proportion of hard and soft segments are introduced into the molecular structure of the TPU coating, forming a unique phase separation structure. This structure allows the material to maintain sufficient hardness to resist wear and to have a certain degree of elasticity to absorb impact energy when subjected to repeated friction. Experimental data show that after 5,000 standard wear tests, the material surface can still maintain more than 90% of the initial anti-slip performance.

Cutting resistance is another important feature of this material. The existence of the meta-aramid fiber layer plays a key role, and its high strength and low modulus properties can effectively disperse the cutting force. According to the research results of the journal Polymer Testing (2020), when the cutting angle is 45°, the material’s cutting resistance can reach Level 4 level EN 388:2016 standard, which means it can withstand at least 30N cutting forces without Destroyed.

In terms of chemical resistance, the TPU outer layer has excellent chemical stability and can withstand the erosion of most common industrial chemicals. Laboratory tests show that after soaking in an acid-base environment with pH 2-12 for 24 hours, the physical performance drops by less than 5%, far exceeding the performance retention requirements specified in ISO 3175:1995. This excellent chemical resistance makes the materials particularly suitable for use in chemical, pharmaceutical and other industries.

Analysis of industrial application examples

The application of inter-cotton composite TPU anti-slip fabrics in the industrial field has achieved remarkable results, especially in high-risk industries such as metal processing, petrochemicals and construction. Taking a well-known German auto parts manufacturing company as an example, the rate of work-related accidents decreased by 42% after the company introduced gloves made of this material in its stamping workshop. Specifically, in the steel plate handling operation, the problem of unstable grip caused by grease pollution by workers has been fundamentally solved. The anti-slip performance of the new gloves has reduced the operating error rate by 67%.

In the petrochemical industry, a study by Saudi Aramco Petroleum shows that protective gloves made with inter-cotton composite TPU anti-slip cloth perform well when dealing with high temperature pipes and corrosive chemicals. Especially in the maintenance of refining and chemical equipment, the high temperature resistance (up to 200℃) and chemical protection capabilities of the new gloves significantly improve the operating safety of workers. According to data reported by Journal of Occupational Health (2021), the proportion of employees suffering from chemical burns and thermal radiation damage decreased by 38% and 45%, respectively, after using the material.

The construction industry has also benefited a lot. During the Paris Metro expansion project in France, after construction workers wore this glove while working at high altitude, safety accidents caused by tools slipping were reduced by 38%. In addition, due to the material’s wear resistance and tear resistance, the service life of gloves is extended to 2.5 times that of traditional products, directly reducing the labor protection cost of enterprises. According to the Journal of Construction Management and Economics (2020), this improvement alone saves about 15% of the overhead costs for the project.

These practical application cases fully demonstrate the significant role of intercotton composite TPU anti-slip cloth in improving industrial safety and economic benefits. By optimizing protective equipment in the working environment, it not only effectively reduces the incidence of occupational diseases and work-related accidents, but also brings considerable economic returns and social benefits.
