AI Technical Summary
Existing leather-based fabrics are prone to displacement and peeling between layers due to long-term stress or repeated bending, resulting in a loose structure and difficulty in recovering deformation after being subjected to stress, affecting appearance and performance.
It adopts a multi-layer composite structure consisting of a mesh surface layer, a high-strength base fabric layer, a polyurethane microporous foam layer, a moisture-absorbing transition layer, and a skin-friendly layer. It is connected by adhesives and stabilizing threads, and through holes, grooves, and embedded parts are set between the layers to enhance the bonding strength and resilience.
It effectively avoids interlayer displacement, improves structural stability and resilience, enhances interlayer adhesion, improves tactile smoothness, and extends service life.

Abstract
Claims
1. A multi-layer composite leather base fabric, characterized by: It includes a mesh surface layer (1), on which breathable holes (2) are formed. A high-strength base fabric layer (3) is connected to the bottom end of the mesh surface layer (1) by an adhesive. A polyurethane microporous foam layer (4) is cast to the bottom end of the high-strength base fabric layer (3). A moisture-absorbing transition layer (5) is connected to the bottom end of the polyurethane microporous foam layer (4) by an adhesive. A skin-friendly layer (6) is connected to the bottom end of the moisture-absorbing transition layer (5) by an adhesive.
2. The multi-layer composite fabric of claim 1, wherein: A stabilizing thread (7) is stitched around the mesh surface layer (1), high-strength base fabric layer (3), polyurethane microporous foam layer (4), and moisture-absorbing transition layer (5). The stabilizing thread (7) passes through the above four layers and then passes around the support arm (101) of the mesh surface layer (1) in sequence.
3. The multi-layer composite fabric of claim 1, wherein: The high-strength base fabric layer (3) has several through holes (8). When the polyurethane microporous foam layer (4) is poured onto the high-strength base fabric layer (3), part of the polyurethane microporous foam layer (4) flows into the through holes (8) to form an embedded part (401).
4. The multilayer composite leather base fabric according to claim 1, characterized in that: On the opposite sides of the polyurethane microporous foam layer (4) and the moisture-absorbing transition layer (5), and on the opposite sides of the moisture-absorbing transition layer (5) and the skin-friendly layer (6), a number of grooves (9) are opened by laser. When the adhesive is applied, the adhesive covers and fills the grooves (9) to make its adhesion stronger.
5. The multi-layer composite fabric of claim 1, wherein: The skin-friendly layer (6) wraps the stabilizing threads (7) on one side of the moisture-absorbing transition layer (5).
6. The multi-layer composite fabric of claim 1, wherein: The high-strength base fabric layer (3) is made of polyester fiber woven with gaps between fibers.
7. The multi-layer composite fabric of claim 1, wherein: The moisture-absorbing transition layer (5) is made of cotton fiber.
