The functions of TPU composite materials are primarily reflected in the following aspects:
1. Cold protection and thermal insulation
Due to their lightweight and flexible nature, TPU composite materials are frequently used for cold protection. They effectively retain body heat and minimize heat loss, thereby providing essential warmth in cold weather.
2. Excellent breathability
The foam component of TPU composite materials consists of interconnected air cells, a structure that imparts good breathability. This allows for free air circulation in products utilizing these materials, helping to maintain comfort and prevent a sensation of dampness.
3. Shape stability
TPU composite materials exhibit excellent shape stability, meaning they can rapidly return to their original form after being subjected to external forces. This characteristic makes them highly valuable for manufacturing products that require the maintenance of a specific shape.
4. Dimensional stability and elasticity
TPU composite materials allow for the bonding of face fabrics and linings that might otherwise be difficult to cut or sew individually, thereby ensuring dimensional stability. At the same time, they possess appropriate elasticity, enabling them to adapt to various shapes and size requirements.
5. Enhanced fabric performance
By adjusting fabric combinations and bonding conditions, TPU composite materials can improve properties such as hand-feel, drape (or "body"), and breathability. This enables designers to tailor fabric characteristics to meet specific design requirements.
6. Simplified manufacturing processes
The use of TPU composite materials significantly simplifies garment manufacturing processes. Since the outer fabric and lining can be cut and sewn together, processing steps and time are reduced, leading to increased production efficiency.
