Soundproofing or sound-absorbing material

Abstract

The described and claimed soundproofing material is planar and has an inhomogeneous structure. It consists of a textile or mesh having relatively thick, adjacent longitudinal components and relatively thin components running in the transverse direction at a spacing from one another. Longitudinal microslits are formed between the longitudinal components by the distribution of the thin transverse components. The width of the microslits amounts to 0.01 and 0.4 mm, and the thickness of the longitudinal components amounts to at least five to ten times that of the microslits.

1 . A soundproofing material having an essentially flat structure exhibiting microslits therein,
 characterized in that it exhibits an essentially flat and inhomogeneous structure having components which extend in the longitudinal and the transverse direction of the material, wherein the microslits run in the longitudinal direction and constitute interspace sections between the longitudinal components of the material, and wherein the successive longitudinal microslits are separated from one another by transverse components of the material.   
     
     
         2 . The soundproofing material according to  claim 1 , characterized in that it is a mesh or a textile, wherein the longitudinal or warp components differ from the transversal or weft components, and wherein the longitudinal components, only separated by the transverse components, are arranged closely together and the transverse components run at a parallel and alternating spacing from one another. 
     
     
         3 . The soundproofing material according to  claim 1 , characterized in that the thickness of the transverse components, which essentially equals the width of the microslits, ranges from 0.01 to 0.2 mm. 
     
     
         4 . The soundproofing material according to  claim 1 , characterized in that the length of the microslits, which corresponds to the interspacing of the transverse components in the longitudinal direction, ranges from 1 to 20 mm. 
     
     
         5 . The soundproofing material according to  claim 1 , characterized in that the transverse components consist of flexible filaments. 
     
     
         6 . The soundproofing material according to  claim 1 , characterized in that the transverse components consist of fibers. 
     
     
         7 . The soundproofing material according to  claim 1 , characterized in that the longitudinal components consist of relatively rigid profiled rods or fibers having a thickness amounting to at least five times, preferably five to ten times that of the transverse components. 
     
     
         8 . The soundproofing material according to  claim 1 , characterized in that the longitudinal components are relatively rigid and barely undulated, while the transverse components are thinner and more flexible and wrap around the longitudinal components, whereby the microslits essentially extend without warping. 
     
     
         9 . The soundproofing material according to  claim 1 , characterized in that the components of the material consist of glass fibers or of metal. 
     
     
         10 . A method for manufacturing the soundproofing material according to  claim 1 ,
 characterized in that parallel longitudinal components in the form of profiled rods or fibers in the longitudinal direction are connectively woven or interlaced together by means of transverse components in the form of filaments or fibers, wherein the longitudinal components are adjacent to one another and only separated from one another by the transverse components alternatingly incorporated over and under the longitudinal components as well as at a distance from one another so that microslits are produced between the longitudinal components.   
     
     
         11 . The method according to  claim 10 , characterized in that the components are selected so that the thickness of the longitudinal components is at a (5-10):1 ratio to the transverse components. 
     
     
         12 . The method according to  claim 10 , characterized in that unwanted parasitic gaps between the components, which differ from the microslits, and which can occur at those points where components intersect can be closed by pressing or rolling the material obtained.
