CNOxford PU coated fabric has become a cornerstone in the realm of outdoor gear, fashion, and industrial applications due to its unique blend of durability, water resistance, and lightweight flexibility. This article delves into the intricate details of this fabric, exploring its composition, manufacturing process, advantages, disadvantages, and diverse applications.
What Is Oxford PU Coated Fabric?
Oxford fabric is characterized by its basketweave structure, typically woven from polyester or nylon fibers. When a layer of polyurethane (PU) is applied to one side of this fabric, it enhances the material's water resistance and durability without compromising its breathability and flexibility .
Manufacturing Process
The creation of Oxford PU coated fabric involves several meticulous steps:
Material Selection: The base fabric is chosen, usually 210D, 420D, or 600D polyester or nylon, depending on the desired weight and strength.
Coating Application: A layer of PU is applied to the fabric using techniques like knife-over-roll or calendar coating. These methods ensure a uniform distribution of the coating.
Curing: The coated fabric is then heated to solidify the PU layer, typically at temperatures ranging from 110°C to 130°C for 2 to 5 minutes.
Finishing: Additional treatments may be applied to enhance properties such as UV resistance, mildew resistance, or to achieve specific aesthetic effects.
Advantages
1. Water Resistance
The PU coating significantly improves the fabric's ability to repel water, making it ideal for products exposed to the elements.
2. Durability
Oxford PU coated fabric exhibits high resistance to abrasions, tearing, and punctures, ensuring longevity even under harsh conditions Derflex.
3. Lightweight and Flexible
Despite its robust properties, the fabric remains lightweight and flexible, offering comfort and ease of use in various applications.
4. Breathability
The PU coating allows for a degree of breathability, preventing moisture buildup and enhancing user comfort.
5. Aesthetic Versatility
Available in a wide range of colors and finishes, Oxford PU coated fabric can be tailored to meet specific design requirements.
Disadvantages
1. Limited Waterproofness
While the PU coating offers water resistance, it may not withstand prolonged exposure to heavy rain or submersion, as the coating can absorb water over time

2. Environmental Impact
The production of PU coatings involves chemicals that can have environmental implications. However, PU is generally considered more eco-friendly than PVC coatings, which contain harmful substances like chlorine and lead.
3. Potential for Coating Degradation
Over time, exposure to UV rays and harsh cleaning agents can degrade the PU coating, leading to reduced performance.
Applications
Oxford PU coated fabric's versatility makes it suitable for a wide array of products:
Outdoor Gear: Tents, backpacks, and rain jackets benefit from the fabric's water resistance and durability.
Luggage: The fabric's strength and lightweight nature make it ideal for suitcases and travel bags.
Workwear: Its abrasion resistance is advantageous for protective clothing.
Home Furnishings: Items like cushions and curtains utilize the fabric's aesthetic appeal and durability
