Is PVC laminated fabric softer than PVC coated fabric?

Introduction

We all encounter PVC fabric in everyday life and industrial manufacturing. But between lamination and coating, which is softer and feels better? Today, we'll examine this question in detail.

Understanding PVC Coated and Laminated Fabrics

PVC coated fabrics are made by applying a layer of polyvinyl chloride (PVC) paste resin directly to the surface of a base fabric. This process is then cured at high temperatures to form a film. This process is like painting fabric, forming a continuous plastic film.

PVC laminated fabrics are made by laminating a pre-made PVC film to a base fabric using heat pressing or adhesives. Think of it like gluing two pieces of paper together: the film and fabric are made separately and then joined.The fundamental differences between these two processes determine their final feel.

Why is lamination generally softer?

In most cases, PVC laminated fabrics are softer and feel better than PVC coated fabrics. The reasons for this are primarily due to the process and structure:

1. Process Determines Hand Feel: "Impermeation" vs. "Lamination"

Coated Fabrics: PVC paste resin partially penetrates the gaps between textile fibers at high temperatures. Upon cooling, the resin not only forms a film on the surface but also solidifies within the fibers, making the fabric stiff and rigid, with a "plastic" feel when bent.

Laminated Fabrics: The PVC film is pre-made and bonded only to the base fabric with an adhesive. It penetrates the fabric fibers minimally, preserving the base fabric's inherent softness and bulk. The film can be made very thin and flexible, resulting in a more pliable feel.

2. The Film's Greater Plasticity

The PVC film used in the lamination process is independently produced, allowing manufacturers to better control its thickness, elasticity, and additive formulation (such as plasticizers). This allows for the production of ultra-thin, highly elastic films designed for a soft touch.

In contrast, the thickness and softness of the coating process are more difficult to precisely control; excessively thick coatings can result in noticeable stiffness.

3. Base Fabric Selection

Because the lamination process does not affect the fabric's inherent structure, higher-count, softer base fabrics (such as high-quality polyester or cotton blends) can be used to further enhance the softness of the finished product. Coated fabrics tend to use a denser base fabric to better hold the coating.

How to Choose Based on Softness?

If your product will come into direct contact with the skin, or require frequent bending and folding, and you're seeking a more premium feel, PVC laminated fabric is a better choice. Coated fabrics also have advantages. While PVC-coated fabrics may feel stiffer, the coating's permeability generally results in superior water resistance, abrasion resistance, and durability, all at a lower cost. Common applications for PVC-coated fabrics include outdoor tents, awnings, truck tarps, and cargo covers.

Conclusion

In summary, the process principles behind PVC laminated fabrics demonstrate their superior softness, elasticity, and tactile feel compared to PVC-coated fabrics. This softness not only enhances comfort but also improves foldability and fit.
