Reasons of drying TPU material before TPU tape production

TPU tape production includes several steps. As TPU is the only material for TPU elastic tape, the processing of TPU raw material is really important. Therefore, one crucial step in the production of TPU elastic tape involves the meticulous drying of raw materials.

TPU (Thermoplastic Polyurethane) material possesses a notable characteristic during production—it is prone to absorbing moisture. This implies that TPU raw materials can absorb moisture when exposed to the air. When TPU raw materials contain moisture, the resulting elastic tape are susceptible to quality issues, with the most common being the formation of bubbles.

TPU tape containing moisture may form bubbles during the production process. In the process of sewing and shaping, these bubbles can destabilize the internal physical structure, increasing the risk of fractures. The generation of substandard products not only impacts product quality but also increases labor, time, and material costs for clothing manufacturers. This not only harms quality but also has a negative impact on production efficiency and economic benefits.

To avoid the bubbles showing, before the production of TPU elastic tape, raw materials must undergo a rigorous drying process. This is typically accomplished through a specialized drying machine, ensuring that moisture is completely eliminated from TPU raw materials before production begins. The temperature and time during the drying process are critical factors. Generally, TPU raw materials are placed in a drying machine and baked at a moderate temperature of 90 degrees Celsius for 2 hours. This balance of time and temperature is aimed at removing moisture without compromising the properties of TPU raw materials.

Through a carefully designed raw material drying process, manufacturers can ensure that the quality of TPU elastic tape begins with the very first step of production. The importance of this step extends beyond the surface, influencing the final product's strength, elasticity, and durability.

In TPU elastic tape production, quality control is indispensable. By emphasizing the raw material drying process, manufacturers can ensure high-quality products from the source, improving production efficiency, reducing defect rates, and providing customers with more reliable elastic band products. In this continual improvement manufacturing process, quality is assured, ensuring that TPU elastic tape perform optimally across various applications.
