Differences in the Processing of PVC Laminated and Coated Fabrics

Introduction

PVC fabrics are widely used for their waterproof and durable properties. Common PVC fabrics on the market are primarily manufactured through two processes: lamination and coating. What are the differences between these two fabric types? This article will provide an in-depth analysis of the process differences between PVC laminated and coated fabrics, helping you fully understand the characteristics and application scenarios of these two fabrics.

What is PVC laminated fabric?

PVC laminated fabrics are produced by combining a PVC film with a base fabric under high temperature and pressure. This process resembles a "sandwich" structure, with the PVC film, acting as an intermediate layer, permanently laminated between two fabric layers or directly onto the base fabric surface.

What is PVC coated fabric?

PVC coated fabrics are produced by applying a liquid PVC mixture directly to the base fabric surface using a doctor blade or roller coating method, followed by oven heating and curing to form a uniform coating. This process is similar to "painting" the fabric, creating a continuous layer of PVC.

Characteristics and Applications of PVC Laminated Fabrics

PVC fabrics produced through the lamination process offer excellent durability and dimensional stability, resisting peeling even after long-term use. Due to its processing characteristics, laminated fabrics can be produced with more complex patterns and three-dimensional effects, making them widely used in high-end outdoor equipment, military equipment, and professional protective clothing.

Another advantage of laminated fabrics is the ability to choose different base fabrics, thereby adjusting the performance of the final product. For example, choosing a breathable base fabric can create a functional fabric that is both waterproof and breathable, something that is difficult to achieve with coated fabrics.

Features and Applications of PVC Coated Fabrics

The main advantages of coated fabrics are low production costs and simple processing, allowing for rapid, large-scale production. Coated fabrics provide a completely waterproof barrier, making them widely used in simple tents, tarpaulins, luggage materials, and low-end protective clothing.

However, coated fabrics have the disadvantage of cracking and flaking over time, especially in areas that are repeatedly folded or bent. Furthermore, coated fabrics generally have poor breathability, making them unsuitable for clothing that requires prolonged wear.

How to Choose the Right Fabric?

The decision between PVC laminated and coated fabrics should be based on specific application requirements. Laminated fabrics should be chosen for applications requiring high strength and durability, such as high-end outdoor equipment and long-term protective gear. Projects with limited budgets and less demanding durability may consider coated fabrics. Products requiring breathability and waterproofing should prioritize lamination, while those requiring simple waterproofing can opt for coated fabrics.

Conclusion

While both PVC laminated and coated fabrics offer waterproofing, their production processes, performance characteristics, and application scenarios differ significantly. Lamination creates a highly durable composite material through physical bonding, while coating provides an economical and practical waterproofing solution through surface coating.
