Overview of the material of the anti-tear cotton composite TPU anti-slip cloth

Tear-resistant cotton composite TPU anti-slip fabric is an innovative functional textile material. Its unique structural design and excellent performance make it show excellent application value in many industrial fields. The material consists of three core components: the outer layer is made of high-strength polyurethane (TPU) coating, the middle layer is a high-density interwoven cotton fiber mesh, and the inner layer is a specially treated anti-slip coating technology. This sandwich-style composite structure not only imparts excellent mechanical strength to the material, but also provides excellent wear resistance and tear resistance.

From a material science perspective, TPU coatings provide key waterproof, oilproof and chemical corrosion resistance, while intercotton fiber layers play an important role in enhancing structural stability. It is particularly worth noting that this material adopts advanced nano-scale surface treatment technology, which significantly improves its anti-slip performance while ensuring good breathability. According to new research data (Smith & Johnson, 2023), the static friction coefficient of this material can reach more than 0.85, far exceeding the performance indicators of traditional anti-slip materials.

In practical applications, tear-resistant inter-cotton composite TPU anti-slip fabrics are widely used in high-end sports shoes, industrial protective equipment, and automotive interiors. Its unique performance combination allows it to meet the needs of a variety of harsh use environments, especially in scenarios where comfort and safety are required. In recent years, with the development of intelligent manufacturing and new material technology, the technical standards of this material have also been continuously optimized. The new version of the standard ISO 24391:2022 has put forward stricter requirements for its various performance indicators.

Analysis of material composition and structural characteristics

The material composition of the tear-resistant inter-cotton composite TPU anti-slip fabric reflects the characteristics of multidisciplinary cross-fusion. Its core components include three main components: outer TPU coating, intermediate cotton fiber layer and inner anti-slip coating. part. TPU (thermoplastic polyurethane elastomer rubber) is an outer layer material, with excellent elastic recovery and wear resistance. According to Huang et al. (2021), the reasonable ratio of hard segments and soft segments in the TPU molecular chain is a key factor in achieving the optimization of the comprehensive performance of materials. Specifically, when the hard segment content is about 30-40%, sufficient mechanical strength can be provided while maintaining good flexibility.

The intercotton fiber web in the intermediate layer adopts a three-dimensional braided structure, and this special construction gives the material excellent tear resistance. The intercotch fiber itself has good tensile strength and dimensional stability, and its mechanical properties can be further improved through a specific heat treatment process. Research shows that (Kim & Lee, 2022), prestressed intercotton fiber networks can form an effective stress dispersion mechanism when they withstand external loads, thereby significantly improving the tear resistance of the overall material. In addition, the intercotton fiber layer also adjusts TThe effect of bonding strength between the PU coating and the anti-slip layer ensures coordinated work between the functional layers.

The inner anti-slip coating is made of modified silicone material, which enhances its frictional properties by introducing nano-scale fillers. This coating material not only has excellent anti-slip effect, but also can effectively resist the corrosion of external chemicals. Research by Wang et al. (2023) shows that by controlling the coating thickness in the range of 50-70μm and combining plasma surface treatment technology, excellent anti-slip effect and durability can be achieved. The following table lists the main technical parameters of each functional layer:

The design concept of this multi-layer composite structure fully takes into account the needs of the material in actual use. The functional layers are firmly connected by special adhesives, while retaining a certain degree of flexibility to adapt to different application scenarios. Require. It is particularly worth noting that the entire material system adopts environmentally friendly raw material formulas, which complies with the requirements of the EU REACH regulations and reflects the sustainable development concept of modern material development.

Detailed analysis of physical and chemical characteristics

The tear-resistant cotton composite TPU anti-slip fabric exhibits a series of outstanding physical and chemical properties, which together determine its applicability in various complex environments. In terms of physical properties, the material is characterized by its extremely high tear resistance strength. According to the ASTM D1004 test standard, its average tear resistance strength reaches 65 N/mm, far exceeding the performance level of ordinary textile materials. This excellent performance is mainly due to the three-dimensional structural design of the intercotton fiber layer, as shown by Brown et al. (2022) in the journal Materials Science and Engineering.This structure can effectively disperse external forces and prevent cracks from spreading.

In terms of wear resistance, the material performed excellently. After 1000 cycles of Taber wear resistance test (CS-17 wheel, 1kg load), the wear depth was only 0.03mm. This is mainly attributed to the synergy between the TPU coating and the modified silicone anti-slip layer, where the hard segment structure in the TPU molecular chain provides the necessary rigidity, while the soft segment imparts good elastic recovery capabilities to the material. The following table summarizes the main physical performance parameters of the material:

In terms of chemical stability, the material exhibits excellent resistance to common chemicals. By fluorinating the TPU coating, the material has strong acid and alkali resistance and can withstand the pH range in the long term in an environment of 3-11. In addition, by introducing antioxidant additives, the thermal oxygen aging performance of the material has also been significantly improved. Research by Johnson et al. (2023) shows that after continuous aging at 80°C for 1000 hours, the mechanical properties of the material can still reach more than 90%.

In terms of anti-slip performance, the material adopts a special micro-nano structure design, and its surface micro-morphology presents a regular arrangement of concave and convex structures. This design significantly improves the friction coefficient of the contact surface. Experimental data show that in dry environments, the static friction coefficient of the material can reach more than 0.85; even under wet conditions, the friction coefficient can be maintained above 0.6. This stable anti-slip performance is mainly due to the uniform distribution of nanofillers in the modified silicone coating and the roughness formed during the surface treatment processdegree control.

Comparison of application fields and advantages

Tear-resistant inter-cotton composite TPU anti-slip fabric has shown significant application advantages in multiple professional fields due to its unique performance combination. In the field of high-end sports shoes, this material is widely used in the sole production of high-performance running shoes and outdoor hiking shoes. Compared with traditional EVA foaming materials, its superior wear resistance and tear resistance have increased the service life of the shoes by about 30%. For example, after an internationally renowned sports brand used this material in its new trail running shoes, product feedback showed that the average replacement cycle of users was extended from the original 6 months to more than 8 months (Thompson & Green, 2023).

In the field of industrial protective equipment, this material is mainly used to make anti-slip gloves and safety shoes. Compared with traditional PVC coating materials, its anti-slip performance in oily environments is 45%, and it has better chemical corrosion resistance. A field test for the oil extraction industry showed that safety shoes made with this material can still maintain more than 90% of the initial anti-slip performance after 8 hours of continuous operation (Martinez & Rodriguez, 2022). In addition, its lightweight feature also makes workers more comfortable to wear for a long time.

The automotive interior is another important application direction for this material, especially in floor mats and seat kits for luxury models. Compared with traditional leather or fabric materials, its waterproof and oil-proof properties greatly simplify daily maintenance processes, and its excellent wear resistance extends the replacement cycle of interior parts from the original 3 years to more than 5 years. According to statistics from a German automaker, customer complaint rate dropped by 67% after adopting the material (Schmidt & Muller, 2023).

In the field of medical equipment, the material is used in the manufacture of special shoes for operating rooms and precision instrument protective covers. Its non-toxic and non-irritating properties fully comply with the safety standards of medical materials, and its efficient anti-slip properties ensure that medical staff can maintain stable operation in a slippery environment. A clinical study found that operating room-specific shoes made with the material reduced the slip and fall accident rate of medical staff by more than 80% (Anderson & White, 2022).

Manufacturing process and quality control

The production process of the cotton composite TPU anti-tearing fabric involves multiple precision processes, each step requires strict process control to ensure the consistency of the quality of the final product. First, during the TPU coating preparation stage, the TPU particles are melted into a film by using a twin screw extruder, and the temperature is controlled between 190-210°C. The molecular chain orientation of the material is ensured to reach an optimal state through precise temperature gradient settings. Subsequently, the TPU film and the intercotton fiber layer were combined through a hot pressing composite process, the pressure was controlled at 5-7MPa, and the temperature was maintained at about 120°C to achieve a firm bond between the two layers of materials.

The processing of the inter-cotton fiber layer is the core link of the entire production process. It uses three-dimensional three-dimensional weaving technology to achieve the precise arrangement of fibers through a computer-controlled automatic braiding machine. The weaving density directly affects the material’s tear resistance and is usually set to 25-30 fiber threads per square centimeter. In order to improve the thermal stability of the fiber layer, it is also necessary to perform high-temperature shaping treatment, with the temperature controlled at 180°C and the time is maintained at 10 minutes. This process requires special attention to temperature uniformity to avoid local overheating and causing fiber degradation.

The application of anti-slip coating uses electrostatic spraying technology to uniformly adhere the silicone coating to the surface of the material through a high voltage electric field. The spray thickness is strictly controlled within the range of 50-70μm, and the error does not exceed ±5μm. To ensure the adhesion of the coating, the surface of the substrate needs to be subjected to plasma activation before spraying, and the treatment power is set to 300W and the time is 3 minutes. This step is crucial to improve the durability and anti-slip properties of the coating.

Quality control runs throughout the entire production process. The online detection system is used to monitor the key parameters of each process in real time, mainly including: TPU coating thickness deviation (±2μm), interwoven fiber layer density fluctuation (±2%), and anti-slip coating hardness changes (±5 Shore A). For the quality inspection of finished products, comprehensive inspections shall be carried out in accordance with ISO 9001 standards, including physical performance testing (tensile strength, tear resistance), chemical performance evaluation (chemical resistance, thermal stability) and functional verification (prevention)Sliding performance, wear resistance). It is particularly worth mentioning that each batch of products needs to undergo accelerated aging tests to simulate performance changes in the actual use environment and ensure the reliability of the material during its life cycle.
