The invention relates to a high-strength TPU composite thermal fabric and a preparation method thereof, and belongs to the technical field of textile fabrics. According to the technical scheme, the structural performance of the material is improved by adding the hollow microspheres into the sol material between the TPU film and the matrix fiber layer, on one hand, the prepared composite hollow microspheres are distributed in a hexagonal close-packed space, and the dispersed structure is beneficial to forming a stable structure in the material and improving the bonding strength between the materials, so that the bonding strength and the mechanical property of the material are effectively improved. |
