PVC and PU coated Oxford cloth: In-depth analysis of waterproof performance optimization

PVC coated Oxford cloth: innovation and optimization of waterproof performance
PVC has long been a leader in the field of coated Oxford cloth due to its excellent waterproof and moisture-proof properties. In terms of waterproof performance optimization, PVC coated Oxford cloth mainly makes technical innovations in the following aspects:
Coating material and formula optimization:
The selection and formula adjustment of PVC coating materials are the basis for improving waterproof performance. By selecting high-quality PVC resin and adding appropriate amounts of plasticizers, stabilizers and other additives, a tough and dense waterproof layer can be formed. Fine adjustments to the coating formula, such as increasing the amount of waterproofing agent and optimizing the ratio of additives, can further improve the waterproof effect.

Coating process improvement:
The optimization of the coating process is crucial to improving the waterproof performance of PVC coated Oxford cloth. The use of advanced coating technologies, such as blade coating and dip coating, can ensure uniform and bubble-free coating, thereby improving the density and continuity of the waterproof layer. By controlling parameters such as coating thickness, drying temperature and time, the waterproof performance can be further optimized.

Surface treatment technology:
Surface treatment technology is also an important means to improve the waterproof performance of PVC coated Oxford cloth. Using nanotechnology or microporous technology to treat the coating surface can significantly improve the waterproof performance while maintaining breathability. These technologies change the microstructure of the coating surface to form a super-hydrophobic layer, so that water droplets cannot stay on the surface, thereby effectively preventing moisture penetration.

Multi-layer composite structure:
In order to further improve the waterproof performance, PVC coated Oxford cloth can also adopt a multi-layer composite structure. By adding waterproof and breathable membranes, waterproof strips and other materials between different layers, multiple waterproof barriers can be formed to effectively block the penetration of moisture. This structure not only improves the waterproof performance, but also enhances the durability and comfort of the product.

PU coated Oxford cloth: innovation and optimization of waterproof performance
Compared with PVC coated Oxford cloth, PU coated Oxford cloth has also made significant progress in optimizing waterproof performance. PU has been widely used in the field of coated Oxford cloth due to its good elasticity, wear resistance and environmental protection. The following are the main technical innovations of PU coated Oxford cloth in optimizing waterproof performance:
Microporous waterproof and breathable technology:
PU coated Oxford cloth usually uses microporous waterproof and breathable technology to improve waterproof performance. This technology introduces tiny holes in the coating so that air and water vapor can exchange through these holes, blocking the penetration of moisture and rainwater. This microporous structure not only improves the waterproof performance, but also enhances the breathability and comfort of the product.

Cross-linking curing technology:
Cross-linking curing is one of the key technologies to improve the waterproof performance of PU coated Oxford cloth. By introducing a cross-linking agent, chemical bonds are formed between the PU molecular chains to form a strong and dense waterproof layer. This cross-linking structure not only improves the strength and wear resistance of the coating, but also significantly improves the waterproof performance.

Application of environmentally friendly waterproofing agents:
With the improvement of environmental awareness, environmentally friendly waterproofing agents are increasingly used in PU coated Oxford cloth. These waterproofing agents usually use non-toxic and harmless raw materials to form a waterproof layer on the surface of the coating through chemical or physical action. Compared with traditional waterproofing agents, environmentally friendly waterproofing agents not only improve the waterproof performance, but also reduce pollution to the environment.

Tight bonding between the coating and the substrate:
The tight bonding between the coating and the substrate is an important prerequisite for improving the waterproof performance of PU coated Oxford cloth. By optimizing the coating formula and coating process, the adhesion between the coating and the substrate can be enhanced, making the coating more firmly attached to the surface of the substrate. This close combination not only improves the waterproof performance, but also enhances the durability and stability of the product.

Practical application and prospect of waterproof performance optimization
The technical innovation of PVC and PU coated Oxford cloth in optimizing the waterproof performance has achieved remarkable results. These achievements not only improve the quality and performance of the products, but also broaden the application areas and market prospects of the products. In the field of outdoor equipment, coated Oxford cloth with excellent waterproof performance has become the preferred material for making tents, raincoats, backpacks and other products. In the field of building covering materials, coated Oxford cloth is widely used in roof coverings, awnings and other fields due to its good waterproof performance and durability. In the fields of agriculture, transportation, logistics, etc., coated Oxford cloth is also playing an increasingly important role.
