Overview of TPU composite milk silk fabric
TPU (thermoplastic polyurethane elastomer) composite milk silk fabric is a high-tech functional textile material that is widely used in the field of industrial protective clothing. This fabric combines the excellent mechanical properties of TPU and the unique texture of milk silk, showing excellent anti-cut and chemical corrosion resistance. As a thermoplastic elastomer, TPU has high strength, high wear resistance and good flexibility, while milk silk gives the fabric a soft feel and environmentally friendly characteristics with its natural protein components. The combination of the two not only enhances the functionality of the fabric, but also makes it perform well in an industrial environment.
From the application point of view, TPU composite milk silk fabrics occupy an important position in industrial protective clothing due to their unique performance combination. This type of fabric can effectively resist mechanical damage and chemical corrosion, while maintaining high comfort and durability, meeting the strict requirements of modern industry for protective clothing. For example, in chemical, metallurgy, petroleum mining and other industries, staff need to face the threat of sharp objects, high temperature environments and strong corrosive chemicals.

Therefore, this fabric is not only a reflection of technological progress, but also an effective solution to the dual challenges of industrial safety and environmental protection.
Anti-cut performance analysis
The anti-cutting performance of TPU composite milk silk fabrics mainly depends on its internal structural design and material characteristics. The TPU layer provides high strength and wear resistance, while the milk silk fiber enhances the overall toughness and tear resistance of the fabric. According to the research of the famous foreign document “Advanced Materials for Industrial Applications”, the molecular structure of TPU has a high cross-linking density, which allows it to effectively disperse stress when subjected to external forces, thereby reducing the possibility of cutting damage.
Material composition and anti-cutting mechanism
| Materials | Features | The role in anti-cutting |
|---|---|---|
| TPU | High strength, high wear resistance | Distribute cutting forces and enhance physical barriers |
| Shredded Milk | Soft, high toughness | Provides additional buffering layer to prevent depth cutting |
From a microscopic perspective, the polymer chains of the TPU can be rearranged when under pressure to form a tighter structure to resist external pressure. Due to its natural protein components, milk silk fiber has a certain self-repair ability and can restore part of its strength even after slight damage. This double-layer protection mechanism greatly improves the overall anti-cut performance of the fabric.
Test standards and results
The commonly used international anti-cutting test standards include EN388 and ASTM F1790. Experiments conducted according to these standards showed that TPU composite milk silk fabrics performed excellently in tool tests of different levels. The specific data are as follows:
| Testing Standards | Cutting Force (N) | Surface damage degree |
|---|---|---|
| EN388 | >50 | Slight scratches |
| ASTM F1790 | >60 | No obvious damage |
These data show that TPU composite milk silk fabric can not only withstand large cutting forces, but also maintain surface integrity, further proving its reliability in industrial protection.
To sum up, TPU composite milk silk fabric achieves excellent anti-cut performance through its unique material combination and advanced processing technology, providing strong support for industrial protective clothing.
Discussion on chemical corrosion resistance
Another key performance of TPU composite milk silk fabrics in industrial protective clothing is its excellent chemical resistance. This performance is mainly due to the chemical stability of the TPU layer and the natural corrosion resistance of the milk silk fibers. The following will discuss this performance in detail from the two aspects of material properties and practical applications.
Material characteristics and chemical corrosion resistance mechanism
TPU itself has extremely high chemical inertia and can effectively resist the erosion of a variety of acid and alkali solutions and organic solvents. Milk silk fibers, although made of natural proteins, also show good corrosion resistance after special treatment. The following are the specific roles of two materials in chemical corrosion resistance:
| Materials | Chemical Characteristics | Anti-corrosion mechanism |
|---|---|---|
| TPU | Chemical Inert | Stop the penetration of chemical substances |
| Shredded Milk | After special treatment | Reduce the effects of chemical erosion |
The molecular structure of TPU has low water absorption and high chemical stability, which means it is not easily decomposed or eroded by chemicals. The milk silk fiber can significantly improve its corrosion resistance through special chemical treatment, ensuring that it remains stable when exposed to strongly corrosive chemicals.
Experimental verification and application examples
In order to verify the chemical corrosion resistance of TPU composite milk silk fabrics, the researchers conducted several experiments. One of the experiments used common industrial chemicals such as sulfuric acid, sodium hydroxide and methanol for immersion tests. Experimental results show that after soaking TPU composite milk silk fabric in these chemical substances for 24 hours, it still maintains its original physical and chemical properties.
| Chemicals | Immersion time (hours) | Fabric Status |
|---|---|---|
| Sulphuric acid | 24 | No change |
| Sodium hydroxide | 24 | No change |
| Methanol | 24 | No change |
These experimental data fully demonstrate the stability and reliability of TPU composite milk silk fabrics in various chemical environments. In practical applications, this fabric is widely used in chemical plants, laboratories and other workplaces where chemicals need to be exposed to chemicals, providing effective protection for staff.
To sum up, TPU composite milk silk fabrics show excellent chemical corrosion resistance through its unique material characteristics and advanced processing technology, making it an ideal choice for industrial protective clothing.
