By accurately adjusting the temperature, pressure and speed parameters, the TPU film is evenly extended in both vertical and horizontal directions, forming an ideal microstructure. The second is the composite technology of environmentally friendly adhesives, which have excellent hydrolysis resistance and bonding strength to ensure a firm bond between the fabrics of each layer. In addition, ultrasonic welding technology is introduced to handle the edges of the fabric, which not only ensures sealing but also avoids the stress concentration problem caused by traditional sewing.
The outstanding technical highlight of this fabric is its ability to achieve all-round elastic extension. Through special fiber arrangement and braided structure design, the fabric can maintain good elasticity in the warp, weft and diagonal directions. This omnidirectional elasticity not only improves wear comfort, but also better adapts to the complex deformation needs of human body during movement. According to the journal Advances in Textile Engineering, this omnidirectional elastic design can increase the fit of fabrics during movement by more than 25%.
In terms of functionality, the fabric integrates a variety of advanced technologies. The TPU film layer adopts nano-enhanced technology, which greatly improves its wear resistance and tear resistance while retaining excellent flexibility. The fleece layer is designed through microporous structure to enhance air flow and warmth. In addition, the surface of the fabric has been specially trimmed to give it anti-fouling, oil-proof and anti-bacterial functions, further enhancing its use value. The organic combination of these technological innovations makes the four-sided composite TPU fleece fabric with comprehensive functional advantages while maintaining lightweight.
