What are the differences between Fabric with Knitted PVC and TPU behind and general products?
Fabrics with a knitted PVC (Polyvinyl Chloride) and TPU (Thermoplastic Polyurethane) backing differ from general fabrics and products in several key ways due to their specialized composition and intended applications:
Waterproofing:
Fabrics with knitted PVC and TPU backing are specifically designed to provide superior waterproofing capabilities. This makes them suitable for applications where protection from moisture and water ingress is essential. In contrast, many general fabrics are not inherently waterproof and may require additional treatments for water resistance.
Durability: These specialized fabrics are known for their durability and resistance to wear and tear. The combination of PVC and TPU backing enhances the fabric's ability to withstand abrasion, making it suitable for rugged applications. General fabrics may not possess the same level of durability.
Flexibility: The inclusion of TPU in the backing of these fabrics imparts flexibility and elasticity. This makes them more comfortable to wear and easier to manipulate in applications that require stretch and movement. In contrast, some general fabrics may lack the same degree of flexibility.
Specific Applications: Fabrics with knitted PVC and TPU backing are typically chosen for specific applications where their unique properties are required. Examples include rainwear, protective clothing, inflatable structures, and outdoor gear. General fabrics are more versatile but may not excel in specialized areas like waterproofing.
Weight and Thickness: These specialized fabrics may have varying thicknesses and weights based on the intended use. General fabrics come in a wide range of weights and thicknesses to suit different applications.
Breathability:
Fabrics with knitted PVC and TPU backing may have limited breathability due to their waterproofing properties. General fabrics vary widely in terms of breathability, with some designed for optimal air circulation and moisture management.
Cost: Specialized fabrics with PVC and TPU backing can be more expensive than general fabrics due to the added technology and performance characteristics they offer. The cost difference reflects their suitability for specific applications.
Maintenance: Proper care and maintenance instructions may differ between specialized fabrics and general fabrics. It's important to follow the manufacturer's guidelines to ensure the longevity and performance of products made from these materials.
Fabric with Knitted PVC and TPU behindWhat is the function of the TPU layer on the back?
Flexibility and Elasticity: TPU is known for its flexibility and elasticity. The presence of the TPU layer enhances the fabric's ability to stretch and bend without losing its shape. This makes the fabric more comfortable to wear and more accommodating of body movements in applications such as clothing and outdoor gear.
Sealing and Waterproofing: TPU is often used as a waterproofing element. It creates a barrier that prevents water from penetrating through the fabric. In combination with the PVC layer on the front, the TPU layer helps ensure that the fabric is fully waterproof. This is particularly important in applications where moisture resistance is critical, such as rainwear and outdoor gear.
Durability: TPU contributes to the overall durability of the fabric. It helps protect the fabric from abrasion, wear, and tear. This makes the fabric suitable for rugged applications where it may come into contact with rough surfaces or experience mechanical stress.
Bonding and Adhesion: TPU can form strong bonds with both the knitted or woven textile layer and the PVC layer. This ensures that the layers remain securely bonded together, preventing delamination or separation over time. The TPU layer acts as a bonding agent.
Protection: The TPU layer provides an additional layer of protection to the fabric. It shields the fabric from environmental elements such as UV radiation, chemicals, and contaminants. This helps maintain the fabric's integrity and appearance.
Enhanced Performance: The TPU layer contributes to the overall performance of the fabric, making it suitable for various demanding applications. It can improve the fabric's resistance to punctures, tears, and abrasions.
Air Tightness: In applications where air retention is important, such as inflatables and air structures, the TPU layer helps create an airtight seal, preventing the escape of air or gas.
