Utility model content

The purpose of this utility model is to provide a sound-absorbing cotton with a concave-convex structure based on spunlace composite technology to solve the problem that the existing sound-absorbing cotton is easily affected by extrusion deformation in the above background technology, and the sound-absorbing effect is poor during actual use. Afterwards, it is easy to squeeze and deform, which affects the sound-absorbing effect and has a short service life.

In order to achieve the above purpose, the utility model provides the following technical solutions: a sound-absorbing cotton with a concave-convex structure based on spunlace composite technology, including a sound-absorbing cotton base cloth, and a sound-insulating cotton base cloth is provided on the side away from the sound source above the sound-absorbing cotton base cloth. The bottom fabric, and the sound-absorbing cotton base cloth is provided with spunlace composite protrusions, and the bottom of the sound-absorbing cotton base cloth is provided with spunlace composite mesh sound-absorbing cotton, and the interior of the spunlace composite mesh sound-absorbing cotton is close to the spunlace composite An air sound-proof room is arranged under the protrusion, and sound-absorbing cotton edging is arranged at the joints of the sound-absorbing cotton base cloth and the spunlace composite mesh-shaped sound-absorbing cotton.

Preferably, the sound-absorbing cotton base cloth has at least four layers, and the four layers of sound-absorbing cotton base cloth are respectively installed on the upper and lower ends of the three spunlace composite mesh sound-absorbing cotton.

Preferably, there are at least ten spunlace composite protrusions, and the ten spunlace composite protrusions are evenly installed on the sound-absorbing cotton base cloth.

Preferably, there are at least ten air sound insulation rooms, and the ten air sound insulation rooms are respectively installed inside the spunlace composite mesh sound-absorbing cotton and close to the bottom of the ten spunlace composite protrusions.

Preferably, the air soundproof room is a hexagonal prism structure.

Compared with the prior art, the beneficial effect of the utility model is: using the spunlace composite technology to form spunlace composite protrusions and spunlace composite mesh sound-absorbing cotton on the sound-absorbing cotton base cloth, and then form countless air sound-proof room structures more Stable, better holding effect, not easy to squeeze and deform, long service life, and the weight of the internal fiber can be adjusted according to different needs, so as to achieve different noise reduction effects.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1 and Figure 2, the utility model provides a technical solution: a sound-absorbing cotton with a concave-convex structure based on spunlace composite technology, including a sound-absorbing cotton base cloth 2, and the upper part of the sound-absorbing cotton base cloth 2 is far away from the sound source The side is provided with a sound-absorbing base cloth 5, and the sound-absorbing cotton base cloth 2 is provided with a spunlace composite protrusion 1, and the bottom of the sound-absorbing cotton base cloth 2 is provided with a spunlace composite mesh sound-absorbing cotton 4, and a spunlace composite mesh sound-absorbing cotton 4 There is an air soundproof room 3 near the bottom of the spunlace composite protrusion 1, and the sound-absorbing cotton base cloth 2 and the spunlace composite mesh sound-absorbing cotton 4 are all connected with a sound-absorbing cotton wrapping 6.

In order to facilitate the formation of a concave-convex structure inside the sound-absorbing cotton, in this embodiment, preferably, the sound-absorbing cotton base cloth 2 is provided with at least four layers, and the four-layer sound-absorbing cotton base cloth 2 is installed on the three spunlace composite mesh sound-absorbing cotton 4 respectively. upper and lower ends;

In order to enhance the noise reduction effect, in this embodiment, preferably, there are at least ten spunlace composite protrusions 1, and the ten spunlace composite protrusions 1 are evenly installed on the sound-absorbing cotton base cloth 2;
