no. 1 example

[0024] figure 2 It is the first specific example of the present invention, a non-woven material art sound-absorbing body for walls or ceilings, which includes an art decoration layer (1), a non-woven material sound-absorbing layer (2) and a hard fixing layer (3). The art decoration layer is made of PET fibers with a fineness of 5dtex and a length of 4.5cm through a spunlace process and a weight of 100g / m 2 non-woven material with a thickness of 1.1mm. At the same time, the surface pattern of the art decoration layer material adopts a paint printing method. After the art decoration layer is printed, it is dried by drum drying method, and cut into 1m×10m size, which is individually rolled into rolls. The non-woven sound-absorbing material is formed by melt-blown method, the fiber is PET material, its length is 10cm, plus crimp, and its fineness is 3.5dtex. Melt-blown nonwovens have a thickness of 2cm and a weight of 350g / m 2 , the specification is 1m×10m. The hard fixed la...

[0026] Fig. 3 is the second specific example of the present invention, a nonwoven material art sound absorbing body craft vase, which includes an art decoration layer (1), a nonwoven material sound absorption layer (2) and a hard fixing layer (3). The art decoration layer is made of PET fiber with a fineness of 5.5dtex and a length of 8cm, which is spunlace and has a weight of 150g / m 2 non-woven material with a thickness of 1.5mm. At the same time, the surface pattern of the art decoration layer material adopts a paint printing method. After the art decoration layer is printed, it is dried by drum drying method, and cut into 1m×10m size, which is individually rolled into rolls. The non-woven sound-absorbing material is formed by needle-punching method, the fiber is PET material, the length is 5cm, plus crimp, and the fineness is 3.5dtex. Needle-punched nonwovens have a thickness of 1.5cm and a weight of 300g / m 2 , the specification is 1m×10m. The hard fixed layer is made o...

Abstract

The invention relates to an artistic nonwoven-material sound absorber comprising an artistic decorative layer (1), a nonwoven-material sound absorbing layer (2) and a hard fixing layer (3), wherein the artistic decorative layer is a plane artistic carrier and provided with micropores; the main component of the nonwoven-material sound absorbing layer is porous nonwoven materials; and the hard fixing layer has higher rigidity and is a body, on which the artistic decorative layer and the nonwoven-material sound absorbing layer are attached, and the hard fixing layer can be tightly combined with a rigid body such as a wall, furniture and the like, and can be cut into various shapes so that spatial configuration processing can be easily realized. The artistic decorative layer is printed or coated by natural dyestuff or dopes, the raw nonwoven materials are various environment-friendly fibers, and the hard fixing layer is made of wood or similar composite materials. The artistic nonwoven-material sound absorber has the advantages of preventing the generation of harmful substances in the entire process of production and construction, effectively lowering room noise, and having the functions of beautification, decoration as well as temperature preservation and regulation.

Description

technical field [0001] The invention relates to an artistic nonwoven material sound absorbing body, which simultaneously has the functions of sound absorption, artistic decoration and heat preservation and temperature adjustment. Background technique [0002] Sound-absorbing products are widely used in public buildings, cars and homes, which are closely related to people's working and living environments. From the perspective of design principles, existing sound-absorbing materials or sound-absorbing bodies can be divided into sound-absorbing panels (perforated panels) and porous panels. material class. [0003] 1. Sound-absorbing panel (perforated panel) [0004] Metal sound-absorbing panels: Metal sound-absorbing panels are typical metal micro-perforated sound-absorbing panels, which are mainly used as sound-absorbing body components in sound barrier projects such as road traffic sound barriers, urban track sound barriers, and high-speed rail sound barriers. level. Such...
