This utility model relates to the field of
new materials technology for clothing, specifically a three-layer double-sided
adhesive, comprising a high-temperature TPU, a low-temperature TPU, and a
glassine paper. A layer of low-temperature TPU is disposed on both the top and bottom of the high-temperature TPU, with the bottom layer of low-temperature TPU attached to the
glassine paper. The thickness of the high-temperature TPU is 0.03mm–0.05mm, the thickness of the low-temperature TPU is 0.02mm–0.04mm, and the thickness of the
glassine paper is 0.07mm–0.09mm. This utility model, through the combination of high and low-temperature TPU, allows for quick bonding to sportswear. It provides a certain level of support strength while facilitating bonding. Furthermore, the material is soft, resistant to washing at certain temperatures, and has a high
softening temperature, making it particularly suitable for use in high-intensity sportswear.
