For every field, and in terms of filtering it is a main aspect of non-woven cloth application.The closely bound up air ambient with the mankind
Worsening, the health of the mankind is seriously endangered, traditional air filting material is not that strainability is undesirable, is exactly
It is expensive.Therefore, the non-woven fabric material of high-precision filtration can be realized by needing badly on the market.
Utility model content
To make up the deficiencies in the prior art, it is big, strong that the purpose of this utility model is to provide a kind of filter efficiency height, dust containing capacity
The good gradient filtration complex nonwoven cloth material of power.
The utility model adopts the following technical scheme that：Gradient filtration complex nonwoven cloth material, by spunlace non-woven cloth layer, spin
Bonded non-woven fabrics layer and ultra-fine melt-blown nonwoven layer of cloth composition, three layers of fiber porosity reduce in gradient.Described spunlace non-woven cloth layer
The grammes per square metre scope is 25-50g/m2, thickness 0.3-0.4mm, porosity 90-93%, the spun-bonded non-woven fabrics layer the grammes per square metre scope
For 10-20g/m2, thickness 0.1-0.2mm, porosity 80-90%, described ultra-fine melt-blown nonwoven layer of cloth the grammes per square metre scope is
10-20g/m2, thickness 0.2-0.4mm, porosity 70-80%.
Described spunlace non-woven cloth layer is by viscose rayon, polypropylene fibre or polyester fiber, passes through carding process networking
It is made.
The spun-bonded non-woven fabrics layer is made by polypropylene or polylactic resin.
Described ultra-fine melt-blown nonwoven layer of cloth raw material is acrylic resin.
The beneficial effects of the utility model are：
Ultra-fine melt-blown nonwoven layer of cloth is compound by ultrasonic wave complex method and spunlace non-woven cloth layer and spun-bonded non-woven fabrics layer.Water
The fluffy softness of prick nonwoven cloth layer, porosity are big, and spun-bonded non-woven fabrics layer strength is good, and melt spraying non-woven fabrics layer porosity is minimum, filtering effect
Rate is high.Three layers of fiber porosity reduce trend arrangement in gradient, form the porous media material of three-dimensional chaotic configuration and superfine fibre
Material, there is excellent strainability, realize the purpose of gradient filtration step by step, reach the standard that high-precision filtration occasion uses, subtract
The frequency of filtering material is changed less, reduces cost.The product can be widely applied to air filtration, vehicle exhaust filtering, liquid mistake
The fields such as filter.The composite structure functional, mechanical performance protrude, and can improve in the market common non-woven fabric filtering material
Because long-time is inadequate using strength, filter efficiency is poor, the problems such as pollutant carrying capacity is low, is that common non-woven fabric material is incomparable.
High-precision filtration occasion is can be applied to, has expanded the application field of non-woven fabrics.
