Description
Technical field
The utility model relates to Nonwovens Field, particularly a kind of sound-adsorbing sound-insulating hung composite non-weaving cloth of sandwich construction.
Background technology
Nearly non-weaving cloth is widely used in sound-adsorbing sound-insulating hung field, has the advantage of lightweight, environmental protection, efficient sound absorption.Air layer can strengthen the acoustically effective of non-weaving cloth under certain condition, even can replace the effect of non-weaving cloth at certain frequency domain.If can optimizing the arrangement of by non-weaving cloth and air layer sandwich construction, realize to the efficient obstruct of sound wave, then both can realizing sound-adsorbing sound-insulating hung function, alleviating again the weight of compound fabric.
At present for the MULTILAYER COMPOSITE acoustextile relating to non-weaving cloth, existing research has been paid close attention to and has been close to multilayer sound proof member that three dimensional foam material is formed (2005 years by non-weaving cloth, multilayer acoustical and thermal parts, patent publication No. CN1610611), the multilayer sound insulating material formed by polymer based thermoplastic material and fortifying fibre (2008, there is the structure of improvement, the supatex fabric of acoustics and hot property, patent publication No. CN101115890), the Multilayer composite sound-insulating fabric that the two-layer spunbond MINERVA layer be made up of PE and PP or PET in addition and the reinforcement intermediate layer be made up of PE or PET or PP filament fiber form (2008 years, a kind of multi-component spun-bonded non-woven reinforcement composite material and preparation method thereof, patent publication No. CN101260616).And and there are no the MULTILAYER COMPOSITE non-weaving cloth relating to non-weaving cloth and form with the air layer supported through netting.
Summary of the invention
In order to solve the deficiency of existing technology, the utility model provides a kind of sound-adsorbing sound-insulating hung composite non-weaving cloth of sandwich construction.
The technical solution that the utility model adopts is: a kind of sound-adsorbing sound-insulating hung composite non-weaving cloth of sandwich construction, it is characterized in that, described composite non-weaving cloth is added with by n+1 layer non-weaving cloth and n layer the air layer supported through netting and forms, described n value is positive integer, and described non-weaving cloth is positioned at air layer both sides.
Described composite non-weaving cloth is added with by 11 layers of non-weaving cloth and 10 layers the air layer supported through netting and forms.
Described air layer thickness is 2mm.
Described woven by chemical-fibres filaments through netting, described chemical-fibres filaments is the one in polyester filament, chinlon filament, polypropylene fibre, polyvinyl long filament or polyethylene filament.
The porosity of described nonwoven layer is 85%-95%, and described nonwoven layer average pore size is 5-10 μm.
Described nonwoven layer average pore size is 8.8 μm.
The beneficial effects of the utility model are: the utility model provides a kind of sound-adsorbing sound-insulating hung composite non-weaving cloth of sandwich construction, it is made up of n+1 layer non-weaving cloth and n layer of air layer, wherein, air layer keeps by supporting through netting, the sound-adsorbing sound-insulating hung performance of this non-weaving cloth can regulate by changing the thickness of air layer, the thickness of non-weaving cloth and n value, and this composite non-weaving cloth can be used for the interior material of various cover, screen material and light structure building materials and the vehicles.
