PVC Construction Fabric Manufacturers

PVC Construction Fabric Production Process and Quality Control Standards

1. Production Process

1.1 Raw Material Selection and Formulation

The main raw materials include PVC resin, plasticizers, stabilizers, and additives. ZheJiang Hanlong New Material Co., Ltd. emphasizes independent R&D for formulations, allowing adjustment of flexibility, weather resistance, and wear resistance according to different applications such as tents, membrane structures, and protective materials.

1.2 Coating or Dipping Process

The PVC solution is evenly applied on the base fabric (polyester, nylon, etc.) or impregnated into the fibers. The coating thickness is generally 0.2–1.5 mm, adjustable according to application requirements. ZheJiang Hanlong New Material Co., Ltd. uses advanced coating equipment to ensure uniformity and adhesion.

1.3 Heat Treatment and Curing

After coating, the fabric undergoes heat pressing or baking to ensure complete bonding between PVC and the base fabric, enhancing tensile and tear strength. The curing temperature is usually 120–160℃, with time adjusted according to material thickness and coating ratio.

1.4 Post-Processing

Post-processing includes surface smoothing, flame retardant treatment, waterproofing, and UV protection. ZheJiang Hanlong New Material Co., Ltd. offers customized functional treatments such as waterproofing, flame retardancy, and weather resistance according to customer needs.
