AI Technical Summary
In the current automotive interior trim, the tearable spacer fabric has uneven bonding between the surface layer and the spacer layer during the weaving process, resulting in poor tearing performance.
By adjusting the needle entry point of the comb and the yarn interlacing method, a structurally weakened area is formed to ensure uniform yarn interlacing. In particular, the loose interlacing structure of the spacer layer makes the fabric easier to tear under external force.
It improves the tear resistance of the tearable spacer fabric, ensuring that the airbag deployment is not affected in critical moments, and maintaining the strength and integrity of the fabric.

[0002] Automotive interior refers to the combination of components inside the car for decoration and providing comfort and functionality, including seats, instrument panels, door trim panels, roofs, carpets, center consoles and various interior accessories, etc. These components not only enhance the aesthetics of the interior of the vehicle, but also provide a comfortable ride environment and convenient operation experience for the driver and passengers.
[0003] Currently, tearable spacer fabric is provided at positions such as the instrument panel and the side of the seat. When the airbag needs to be deployed, this fabric can tear quickly and neatly, without hindering the deployment of the airbag. Compared with traditional interior materials, it can provide better safety performance in critical situations.
[0004] However, in order to achieve the effect of tearable spacer fabric, a special connection method is used during weaving to form a tearable structure. However, in existing weaving structures, the connection between the surface layer and the spacer layer is uneven, resulting in poor tearing effect of the subsequent spacer fabric. Therefore, a tearable warp-knitted spacer fabric structure for automotive interior parts is proposed to improve the existing problems. SUMMARY
