How to produce TPU coated webbing?

In the myriad of packaging and fastening solutions, coated webbing is favored for its excellent performance and versatility. Coated webbing is a unique material that combines polyester webbing and TPU to achieve waterproof, wear-resistant, and tear-resistant properties. TPU is not the only option of the coated webbing layer. PVC coated webbing and silicone coated webbing are also widely used. But here we will talk about TPU coated webbing. We will explain the manufacturing process of webbing, with a focus on the production of high-quality coated webbing through TPU extrusion technology.

Firstly, let’s understand the basic manufacturing process of woven webbing. Webbing is usually made from high-strength polyester fibers through weaving. Weaving involves interlacing yarns to form a sturdy structure. The choice of polyester fibers is crucial as their strength and durability directly affect the performance of the webbing. Once weaving is completed, the next step of processing can proceed.

The next step is the coating process with TPU material. To combine TPU with polyester webbing, extrusion technology is typically employed. Extrusion is a process where thermoplastic material is heated and melted, then forced through a die to create a specific shape. During the extrusion process, TPU is heated and melted, then extruded onto the surface of the polyester webbing through a die. This method ensures that TPU is evenly coated on the webbing, forming a waterproof barrier.

TPU extrusion technology is key to producing high-quality coated webbing. The temperature, pressure, and speed during the extrusion process must be precisely controlled to ensure uniform distribution of TPU and good adhesion. Additionally, the design of the die is crucial as it determines the final shape and size of the webbing. Once extrusion is completed, the webbing must go through cooling and curing processes to stabilize the TPU layer.

In addition to coating with TPU, the manufacturing process of coated webbing also includes cutting and edge-sealing steps. Cutting involves slicing the webbing into desired lengths, while edge-sealing treats the cut edges of the webbing to prevent wear and tear. Although these steps may seem simple, they play an important role in ensuring the overall quality and aesthetics of the webbing.

Furthermore, other decorative or functional elements can be added to the coated webbing as needed. For instance, patterns or logos can be printed or embroidered onto the webbing, and accessories such as buckles and zippers can be attached to meet various usage requirements.

In conclusion, the manufacture of coated webbing is a complex process involving multiple steps, each requiring precise operation and strict quality control. TPU extrusion technology plays a crucial role in this process, not only ensuring the waterproofness and wear resistance of the coated webbing but also providing endless design possibilities. Through refined manufacturing techniques and innovative technology, coated webbing has achieved great success in outdoor, luggage, and sports industries, becoming an indispensable material in these fields. In the future, as technology continues to advance, we can expect the performance of coated webbing to be even more outstanding, and its application fields to be even more extensive.
