What is 420D Oxford Fabric?

oxford fabric
420D Oxford fabric is a type of textile material commonly used in the manufacturing of bags, backpacks, tents, and other outdoor gear. The "D" in 420D stands for denier, which is a unit of measurement used to describe the thickness or density of fibers in a fabric. In this case, the fabric is made with fibers that have a denier of 420. Oxford fabric is a type of woven fabric that is known for its durability and strength. It is typically made with a basket-weave pattern, where two or more yarns are woven together in a crisscross manner. This weaving technique gives Oxford fabric its distinctive texture and provides additional strength. The "420D" specification indicates that the fabric is made with yarns that have a denier of 420. Denier is a measure of the linear mass density of the fibers. A higher denier number generally indicates a thicker and more robust fabric. In the case of 420D Oxford fabric, it is relatively lightweight yet still sturdy and suitable for various applications. The fabric is often coated or treated to enhance its water resistance, making it suitable for outdoor and weather-resistant products. It is commonly used in the construction of bags, backpacks, luggage, and other items that require a combination of strength, durability, and water resistance.

The composition of 420D PVC coated fabric typically involves a woven or knit base fabric made from synthetic fibers such as nylon or polyester. These fibers provide strength, durability, and flexibility to the fabric. The PVC coating is then applied to the surface of the fabric, forming a protective layer that enhances the fabric’s waterproof and abrasion-resistant properties.


Differences between Various Oxford Fabrics.

The differences between various Oxford fabrics, including 420D PVC coated fabric, lie in their specific characteristics, manufacturing processes, and areas of application. Oxford fabrics, in general, are characterized by a basketweave pattern and are commonly used in the production of bags, backpacks, tents, and other outdoor gear. Here are some common variations of Oxford fabrics:

210D Oxford: This fabric has a lower denier (210) compared to 420D PVC coated fabric, making it lighter and less durable. It is often used for lightweight bags and backpacks.

600D Oxford: With a higher denier (600), this fabric is heavier and more durable than 420D. It is commonly used for medium-duty bags, luggage, and outdoor furniture.

1680D Oxford: This fabric has an even higher denier (1680) and offers excellent strength and durability. It is suitable for heavy-duty applications, such as military gear, industrial covers, and high-end backpacks.


Characteristics of 420D Oxford Fabric

Strength and Durability

420D fabric, with a denier count of 420, offers moderate strength and durability. While not as robust as higher denier fabrics, it can still withstand regular use and moderate stress. It is suitable for applications that do not require extreme durability.


Water Resistance

The base fabric of 420D, typically made from synthetic fibers like nylon or polyester, offers inherent water resistance. However, the addition of a PVC coating further enhances the fabric’s water-resistant properties. It provides a protective barrier that prevents water from penetrating the fabric, keeping the contents dry.


Abrasion Resistance

The PVC coating on 420D fabric enhances its abrasion resistance. This makes it more resistant to wear and tear caused by rubbing or friction. It is capable of withstanding moderate abrasion, making it suitable for applications where the fabric may come into contact with rough surfaces.

Oxford fabric, including 420D, is generally not highly breathable due to its tight weave and coatings. While it offers some degree of breathability, it may not be as breathable as other lightweight fabrics. This characteristic should be considered when using the fabric in applications where breathability is important.
