Description
Technical field
The present invention relates to a kind of textile fabrics, and in particular to a kind of structure of composite membrane double-layer fabric with sound absorption characteristics.
Background technology
With the continuous development of science and technology, meet the precoat that people's difference Structure of needization has certain function characteristic
Go out not poor, increasingly important role is played in daily life.
Textile fabric quality is frivolous, machinability is good, is produced using fiber institute's yarn of hollow property, then be aided with structure
Design, is increasingly becoming a research hotspot in sound absorption and insulation field.In necks such as Sound insulation for building, home decoration, automobile-used ornament materials
Domain has broad application prospects.
The textile fabric that hollow material is produced has the characteristic of sound-absorbing porous material, according to the sound absorption machine of sound-absorbing porous material
Reason, when sound wave incident is to web surface, the vibration that sound wave generates causes fabric internal voids and the intrapore air of fiber
Movement.Air itself has the function of high frequency sound wave of decaying, while air movement causes between yarn and yarn, fiber and fiber
Between and fibrous inside hole wall friction, due to rubbing and the effect of viscous force makes part acoustic energy be converted into thermal energy, woven face
Thermal energy and ambient enviroment are carried out heat exchange by material, and then by energy dissipation so that textile fabric has certain sound absorbing performance.It is high
Frequency sound wave can be such that the vibration velocity of air particle accelerates, and the speed of heat exchange is also accelerated, this allows for textile material with good
Good high frequency sound absorbing performance.
Studies have shown that weaving sound absorption acoustic material can developmental direction and approach it is very much, but both at home and abroad to textile material inhale
The research of sound sound insulation is less.Research is merely resting in the observational measurement and evaluation of novel textile material mostly, certainly to textile
The system research of body sound absorption characteristics is less, lacks the research to textile sound absorbing performance practicability.Textile material is as sound absorption material
Material, although having great advantage, only by its with other materials is compound could meet people's needs, be preferably applied for house
Residence, building, military affairs, civil aviaton, traffic etc..Cost, performance, all requirements of environmental protection are taken into account, comprehensive utilization is all kinds of hollow
Textile fabric, it is blended to produce yarn, then composite structural design can be as our Future Development weaving noise reduction sound absorption acoustic materials
A direction.New material new process is studied, in conjunction with sound absorption theory and traditional sound absorption structure, is designed both beautiful and practical
The frivolous fabric fabric of quality is a main trend of weaving sound-absorbing material development.
Invention content
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to which now providing one kind produces that simple, cost is relatively low, sound absorption effect
The good structure of composite membrane double-layer fabric with sound absorption characteristics of fruit.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of composite membrane knot with sound absorption characteristics
Structure double-layer fabric, it is characterised in that：It is made of surface layer and inner layer, the surface layer and inner layer are interconnected by weaving；
The outer surface on the surface layer is covered with metal film, and the outer surface of the inner layer is covered with polyurethane film；
The surface layer uses the short fibre of natural hollow/hollow chemical fiber filament core-spun yarn, the short fibre/hollow chemical fiber of natural hollow
The core filaments of filament core-spun yarn are hollow nylon long filament, the covered fiber of the short fibre of the natural hollow/hollow chemical fiber filament core-spun yarn
For the short fibre of natural hollow；
The inner layer uses mixed yarn, and the mixed yarn is by stainless steel fibre, the short fine and hollow chemical fiber long filament of natural hollow
Blended to form, the stainless steel fibre accounts for the 15-30% of mixed yarn gross mass, and the short fibre of natural hollow accounts for mixed yarn gross mass
40-65%, the hollow chemical fiber long filament accounts for the 20-30% of mixed yarn gross mass.
Further, the metal film is metal material, selects stainless steel membrane or aluminium film.
Further, the short fine one or more mixing selected in cotton, ramie, flax of the natural hollow.
Further, the hollow chemical fiber long filament is selected one or more in hollow polyester, hollow polyamide fibre and viscose glue
Mixture.
Further, the thickness of the metal film is 0.01-0.2mm.
Further, the thickness of the polyurethane film is 0.1-1mm.
Beneficial effects of the present invention are as follows：
（1）The inner layer of the present invention selects the mixed yarn of stainless steel fibre, natural hollow fiber and chemical fibre tubular filament, stainless
The thermal coefficient of steel fibre and chemical fibre tubular filament is high, thermal dissipation obtained by capable of effectively changing decaying sound wave, thus
With good sound absorption effect.
（2）The polyurethane film of the present invention uses one side to be to make full use of its elastic damping characteristic attenuation sound wave, separately
One side is that the presence of its porous structure also contributes to absorb sound.
（3）The metal film of the present invention can effectively adjust sound absorption frequency range, so that sound absorbing performance is moved toward low frequency direction, and promoted
In the sound absorption effect of middle low frequency.
