Cold Lamination Production Process of PVC Coated Fabric

The cold lamination process is a coating lamination process performed at room temperature or lower. Unlike traditional hot lamination methods, which require high-temperature processing, the cold lamination method uses a special adhesive to laminate the PVC coating to the base fabric at room temperature, eliminating the need for a high-temperature baking process.

Cold Lamination Production Process

1. Base Fabric Pretreatment

Production begins with base fabric preparation. The base fabric is typically made of synthetic fibers such as polyester and nylon. These base fabrics undergo pretreatment steps such as cleaning and desizing to remove surface impurities and oil stains to ensure good adhesion of the subsequent coating.

2. Adhesive Preparation

The core of the cold lamination process is the formulation of a specialized adhesive. This adhesive typically consists of PVC paste resin, plasticizer, stabilizer, and special additives. It requires precise mixing and thorough stirring to form a uniform paste. The adhesive formulation directly determines the performance and quality of the final product.

3. Coating Process

The prepared adhesive is evenly applied to the base fabric surface using a doctor blade or roller. This step requires precise control of coating thickness and uniformity to ensure the coating is neither too thick (wasting material) nor too thin (affecting product performance).

4. Lamination and Curing

The coated base fabric is laminated with another layer of material (if necessary) and then cured naturally at room temperature or accelerated by ventilation. During this process, the solvent in the adhesive gradually evaporates, forming a strong bond.

5. Post-Processing

The cured product undergoes surface treatment, such as embossing, printing, or special coatings, to enhance its aesthetics and functionality. Finally, after inspection, roll separation, and packaging, the finished product is ready for shipment.

Conclusion

The PVC-coated fabric cold-apply production process represents the latest advancement in coated fabric manufacturing technology, perfectly combining environmental friendliness, efficiency, and cost-effectiveness. For manufacturers, adopting this technology not only enhances product competitiveness but also fulfills corporate environmental responsibility. For consumers, it means higher-quality, more environmentally friendly product choices.
