The synthetic leather uses polyurethane (PU) as the base material, and the surface is embossed to form a texture similar to genuine leather, improving its aesthetics and feel. The wrapping layer 6 is 1.2-2.5 mm thick, possessing good flexibility and abrasion resistance. The surface of the synthetic leather is waterproofed, effectively preventing liquid from seeping into the internal structure. The wrapping layer 6 is dark brown, which is both dignified and resistant to dirt. The synthetic leather has good breathability, which is beneficial for the dissipation of heat inside the cushion. The edges of the wrapping layer 6 are stitched with a double-needle stitching process, enhancing the seam strength and preventing cracking after long-term use. The synthetic leather has a certain degree of elasticity, adapting to the deformation of the cushion and preventing wrinkles from forming due to frequent use. The synthetic leather is easy to clean; stains can be wiped away with a damp cloth to keep the cushion clean. The wrapping layer 6 is fixed to the internal structure with adhesive, ensuring that it will not separate after long-term use. The synthetic leather has good flame retardant properties, improving the safety of the product.
[0029] Example 6:
[0030] like Figures 1-5As shown, the moisture-proof layer 5 is made of ethylene-propylene rubber (EPDM) material. The EPDM material has excellent weather resistance and waterproofness, which can effectively block moisture and humidity from penetrating into the cushion interior. The thickness of the moisture-proof layer 5 is 0.8-1.0 millimeter, which can provide good protection effect without significantly increasing the overall thickness of the cushion. The EPDM material has high tensile strength and can withstand frequent pressure changes without being easily broken. The surface of the moisture-proof layer 5 is specially treated to enhance the adhesion with the upper and lower layers of material, ensuring the stability of the multi-layer structure.
