How is 18 oz vinyl coated PVC fabric made?

18 oz vinyl coated PVC fabric is a PVC coated fabric made by combining vinyl and polyester materials through a coating process. The “18 oz” designation usually refers to the weight of the fabric per square yard, indicating its thickness and strength. Weight is an indicator of fabric thickness and durability, with higher ounces generally indicating thicker, sturdier material. The fabric is coated with vinyl, a synthetic plastic material, and the vinyl coating increases the fabric’s strength, water resistance, and overall weather resistance. It provides extra strength, water resistance, flexibility and chemical resistance, making PVC coated canvas fabric suitable for a variety of demanding applications. Here is a simplified overview of the manufacturing process:

Base fabric preparation:
– The base fabric is usually made of polyester. The strength and durability of 18 oz vinyl coated PVC fabrics are primarily determined by the specifications of the polyester base fabric. The strength of PVC coated canvas fabric can be customized according to the user’s requirements.
– The fabric is woven to the required specifications to form a strong and stable base. Conventional base fabric specifications include 1000 Dtex 9×9/inch, 1000 Dtex 18×16/inch, 1430 Dtex 17×19/inch, 1650 Dtex 15×18/inch, etc. When requesting customization from FLFX PVC polyester fabric supplier, please be sure to tell us the base fabric specifications and application scenarios you require. In this way, even if you don’t know about vinyl coated PVC fabrics, we can make recommendations based on your application scenario.

PVC (polyvinyl chloride) coating preparation:
– PVC is a versatile coating material known for its durability and water resistance. PVC coating can make 18 oz vinyl coated PVC fabrics fireproof, mildewproof, anti-aging, environmentally friendly and other properties. These specific requirements can also be selected according to your own needs before customization.
– The coating process mainly uses a knife coating machine to apply the liquid PVC mixture on one or both sides of the fabric, and then enters the calendering system for processing.

Calendering system:
– After applying the PVC coating, the 18 oz vinyl coated PVC fabric goes through a high-temperature calendering process. A roller system passes the fabric through heated rollers during the calendering process to ensure an even coating and achieve the desired thickness.
– Rolling to help fully bond the PVC to the fabric. And can make 18 oz vinyl coated PVC fabrics have glossy and matte characteristics.

Surface processing:
– Depending on the intended use, PVC coated canvas fabrics are also surface treated with PVDF and acrylic to enhance their appearance or make them easier to clean.

Curing and drying:
– The coated fabric is then cured or dried to set the PVC coating. This can be done by heat treating the PVC so that it cures and adheres firmly to the fabric. The curing process ensures that the PVC coated canvas fabric is water-resistant and resistant to environmental factors.

QC:
– Finished 18 oz vinyl coated PVC fabric undergoes a series of quality control checks to ensure it meets specified standards for thickness, strength and other properties. This will be done using our laboratory.
– Quality control will involve testing PVC coated canvas fabrics for factors such as water resistance, abrasion resistance, flame retardancy, tear resistance and UV resistance.

This PVC coated canvas fabric is suitable for a variety of applications such as truck tarps, industrial covers, outdoor signage and other products requiring weather resistance and durability. Applications for 18 oz vinyl coated PVC fabric include:

• Tarps and Coverings: It is commonly used to manufacture heavy-duty tarps and coverings for outdoor use, providing protection against the elements.
• Industrial Curtains: This fabric is used to create curtains or dividers in industrial settings to separate work areas and control environmental conditions.
• Truck Tarps: Due to its durability and water-resistant properties, this fabric is often used in the manufacture of truck tarps to protect cargo during transportation.
• Outdoor Banners: Can be used for outdoor banners and signage due to its weather resistance and durability.
• Awnings: This fabric is suitable for awnings that need to withstand various weather conditions.

Specific applications will vary depending on the exact properties and specifications of the PVC coated canvas fabric.
