Introduction
Define
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.
Breathability
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.
Applications of 420D Oxford Fabric
Outdoor Gear and Equipment
420D Oxford fabric is commonly used in the production of outdoor gear and equipment such as tents, sleeping bags, backpacks, and camping chairs. Its water resistance and moderate durability make it suitable for these applications, providing protection against the elements and ensuring the longevity of the products.
Backpack and Bags
Due to its combination of strength and lightweight characteristics, 420D Oxford fabric is often used for backpacks, daypacks, and various types of bags. It offers sufficient durability to withstand regular use and abrasion, making it suitable for school bags, travel bags, and sports bags.
Home Furnishings
420D Oxford fabric can also be used in home furnishings, particularly for items that require durability and water resistance. It can be found in the production of outdoor cushions, patio furniture covers, and protective covers for garden equipment or machinery. Its ability to withstand outdoor conditions makes it ideal for these applications.
How to Choose Waterproof 420D Coated Fabric
Durability and Strength
Look for a fabric that offers good durability and strength. Consider the intended use of the fabric and assess whether it can withstand the demands of the application. Check the fabric’s specifications, such as tear strength and tensile strength, to ensure it meets your requirements.
Testing and Certification
It’s beneficial to choose fabrics that have undergone testing and obtained relevant certifications. Look for fabrics that meet industry standards for waterproofing, such as ISO standards or specific certifications like the EN 343 standard for protective clothing against rain. This ensures that the fabric has been evaluated and meets the required performance criteria.
Supplier Selection
Choose a reputable and reliable supplier or manufacturer when purchasing waterproof 420D coated fabric. Research and assess the supplier’s reputation, experience, and customer reviews. Look for suppliers that have a history of providing high-quality fabrics and have good customer support. It’s also beneficial to inquire about their quality control processes and whether they can provide samples or swatches for evaluation.
Quality control measures
Raw Material Inspection
Before production, it is important to conduct a thorough inspection of the raw materials used in the manufacturing of 42D PVC Oxford fabric. This inspection should include checking the quality and specifications of the polyester base fabric and the PVC coating. The dimensions, composition, strength, and overall quality of the raw materials should be assessed to ensure they meet the required standards. Any defects or inconsistencies in the raw materials should be identified and addressed before they are used in the production process.
Coating Thickness Measurement
42D PVC Oxford fabric is known for its PVC coating, which provides waterproofing and durability. It is crucial to measure the coating thickness accurately to ensure consistency and adherence to specifications. Coating thickness can be measured using various techniques such as magnetic induction, eddy current, ultrasonic, or optical methods. By regularly measuring and monitoring the coating thickness, manufacturers can ensure that it meets the desired thickness range, providing the required level of water resistance and durability.
testing procedures
Testing procedures are an integral part of quality control for 42D PVC Oxford fabric. Various tests can be conducted to evaluate the fabric’s performance and adherence to quality standards. These tests may include tensile strength testing, tear strength testing, abrasion resistance testing, colorfastness testing, and water resistance testing. Additionally, tests can be conducted to check the fabric’s resistance to environmental factors like UV radiation or chemicals. By subjecting the fabric to rigorous testing, manufacturers can identify any issues or weaknesses in its quality and make necessary improvements.
Conclusion
In conclusion, 420D coated fabric offers a balance of durability, strength, and water resistance, making it suitable for a variety of applications. When choosing this type of fabric, it is important to consider factors such as durability, waterproof performance, testing and certification, supplier selection, application-specific requirements, and cost-value ratio.
Implementing quality control measures throughout the fabric production process is crucial to ensuring the fabric meets the desired standards. These measures may include raw material inspection, coating thickness measurement, seam strength testing, waterproof testing, abrasion resistance testing, UV resistance testing, and dimensional stability testing.
By carefully considering these factors and implementing quality control measures, you can select a high-quality waterproof 420D coated fabric that meets your specific needs and requirements. This ensures that the fabric performs well, offers longevity, and provides reliable protection in the intended applications.
