As a high-performance textile material, TPU coated fabric is widely used in many fields. To ensure its quality, a rigorous inspection process is essential.
The first is appearance inspection. This is the first step of the inspection. It mainly uses visual inspection to carefully observe whether there are defects on the surface of the coated fabric, such as cracks, bubbles, wrinkles, etc. Any minor appearance defects may affect its performance and life in actual use, so this link requires the inspector to have keen observation.
Next is thickness inspection. With the help of professional thickness measuring instruments, multi-point measurements are made at different positions of the coated fabric, and the average value is taken as the final result. The uniformity of thickness has an important influence on the physical and chemical properties of the coated fabric. Ensuring that the thickness meets the standards is one of the keys to ensure product quality.
Tensile strength and tear strength testing are also important links. The coated fabric is subjected to tensile and tear tests by a tensile testing machine, and its deformation and breaking strength under different tensile forces are recorded. This can evaluate the tensile and tear resistance of the coated fabric during use to ensure that it can withstand the corresponding load.
Air permeability testing is also indispensable. Use an air permeability tester to measure the air permeability of the coated fabric to evaluate its air permeability. Good air permeability is essential for some application scenarios that need to stay dry.
Finally, there is the chemical resistance test. Soak the coated fabric in different chemical reagents to observe whether it changes color, dissolves, peels off, etc. to evaluate its chemical corrosion resistance.
Through the above series of rigorous testing processes, the various properties of TPU coated fabrics can be fully evaluated to ensure that they meet relevant standards and customer needs, and provide high-quality and reliable TPU coated fabric products for all walks of life.
