た。On the other hand, in the second invention, the main structure of the sound absorbing material is divided into two layers: a hardened layer whose main purpose is to have a smooth layer, and a buffer layer whose main purpose is a buffer.
The blending ratio of the heat-fusible fiber and the non-heat-fusible fiber is selected according to the purpose of each layer. By this, in the cured layer, it is necessary that the heat-fusible fiber is blended by 50% or more. And, in some cases, 100%
Accordingly, the non-heat-fused fiber may be blended in 50% or less, and may be 0% in some cases. In the buffer layer, 70% of the non-heat-fused fiber is blended. In some cases, it may be 100%, and accordingly, the heat-fused fiber may be blended in an amount of 30% or less, and may be 0% in some cases. As a result, the sound absorbing material of the second invention has the performance of the sound absorbing material of the first invention, is further improved in economic efficiency, and at the same time has excellent anti-settling resistance.

上するものとなった。According to the first aspect of the present invention,
Since the main component of the floor sound-absorbing material is a single non-woven web layer containing 50% or more of the heat-fusible fiber and a smooth layer formed on the upper surface thereof, the conventionally required soundproofing properties , Sound insulation, loading, economy, etc. cannot be fully provided, and the presence of the smooth layer allows the surface of the floor sound absorbing material to be smooth. No adhesion failure occurred, and the adhesive prevented penetration into the nonwoven web layer. Further, the floor sound-absorbing material is usually cut and adhered in accordance with the shape of the enforced place at the enforcement site, but according to the present invention,
Due to the formation of the smooth layer, there is no fuzz on the surface,
The machinability was extremely good, and the work efficiency was significantly improved. In the second invention, the main body of the floor sound-absorbing material in the first invention is constituted by a single layer of a nonwoven web layer, but instead of the single layer, two layers of a hardened layer and a buffer layer are used. By doing so, the performance of the floor sound absorbing material according to the first invention, such as sound insulation, sound insulation, economy, cutting performance, work efficiency, prevention of penetration of a backing agent, etc., is maintained as it is, and the resistance to settling is further improved. It became.
