[0037] The following combination Attached drawing Further explain the structure of the present invention:
[0038] See Icon 2. From top to bottom, the car carpet includes polyester green carpet 1, PE bonding layer 2, cotton and polyester composite sound-absorbing felt 3 and sound-absorbing foam 4 composite. The density of polyester blanket 1 is 650g / m 2 , The density of PE adhesive layer 2 is 300g / m 2 , The composite sound-absorbing mat 3 is made of 30% cotton fiber and 70% polyester fiber, and the cotton fiber density is 195g / m 2, The density of polyester fiber is 455g / m 2 , The sound-absorbing foam adopts PUR foam with a density of 50kg / m 3 .
[0039] Compared with the existing traditional carpet materials, the high sound-absorbing material has image 3 It can be seen that the high sound absorption material has a higher sound absorption capacity than the existing traditional technology materials.
[0040] The method of making the above carpet is as follows
