Abstract
The invention discloses a novel filtration cloth. The novel filtration cloth comprises a central metal layer and surface non-woven layers. The surface non-woven layers are coated on upper and lower surfaces of the central metal layer. The central metal layer is a metal fiber-woven fabric. The surface non-woven layers are non-woven fabrics obtained by mixing polyester fibers and spandex fibers. The surface non-woven layer comprises 83-91wt% of the polyester fibers. The surface non-woven layer comprises 9-17wt% of the spandex fibers. The novel filtration cloth utilizes an inner core prepared from the metal fibers, can effectively remove static on the particles, can keep filtration cloth permeability and can improve filtration efficiency of a filter screen in use.
Description
Technical field
The present invention relates to filtering material field, particularly relate to a kind of Novel filtration cloth.
Background technology
Filtration is to make the fluid in liquid-solid or gas-solid mixture force, by porous filter medium, SS wherein to be held back, thereby realizes the separated process of mixture, and wherein most important parts are exactly filter medium.The kind of filter medium has a lot, according to material, substantially can be divided into braided material, porous solid, accumulation medium, and the scope of use is also not quite similar.
Braided material is a kind of use filter medium comparatively widely, and volume is frivolous, and good filtration effect can be used in the filtration of liquid-solid or gas-solid mixture, and the scope of application is comparatively extensive.In gas-solid mixture, solid particle easily produces static with external object friction, and therefore, in the process of filtering, solid particle, because static is adsorbed on braided material, stops up pore, and the filter area of minimizing braided material, affects actual filter effect.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Novel filtration cloth, and effectively antistatic, filter efficiency is high.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of Novel filtration cloth is provided, comprise: central metal layer and surperficial nonwoven layers, described surperficial nonwoven layers covers central metal layer upper and lower surface, described central metal layer is the fabric that metallic fiber is made into, described surperficial nonwoven layers is the nonwoven that polyster fibre and spandex fibre are mixed, described polyster fibre accounts for 83% ~ 91% in surperficial nonwoven layers, and described spandex fibre accounts for 9% ~ 17% in surperficial nonwoven layers.
In a preferred embodiment of the present invention, described metallic fiber is a kind of or its combination in aluminum fiber and copper fiber.
In a preferred embodiment of the present invention, described polyster fibre accounts for 83% ~ 91% in surperficial nonwoven layers.
In a preferred embodiment of the present invention, described spandex fibre accounts for 9% ~ 17% in surperficial nonwoven layers.
The invention has the beneficial effects as follows: a kind of Novel filtration cloth that the present invention points out, the inner core that has adopted metallic fiber to make, effectively removes the static on particle, keeps filtering the highly-breathable of cloth, promotes screen pack filter efficiency in use.
The specific embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of Novel filtration cloth, comprise: central metal layer and surperficial nonwoven layers, described surperficial nonwoven layers covers central metal layer upper and lower surface, described central metal layer is the fabric that metallic fiber is made into, described surperficial nonwoven layers is the nonwoven that polyster fibre and spandex fibre are mixed, described polyster fibre accounts for 83% ~ 91% in surperficial nonwoven layers, and described spandex fibre accounts for 9% ~ 17% in surperficial nonwoven layers.
The inner core that a kind of Novel filtration cloth of the present invention has adopted metallic fiber to make, described metallic fiber is a kind of or its combination in aluminum fiber and copper fiber.The fabric that aluminum fiber and copper fiber are made, good toughness, and wear-resisting, resistance to oxidation, electric conductivity is outstanding, can eliminate fast the entrained static of screen pack surface particles, long service life.
Further, described polyster fibre accounts for 83% ~ 91% in surperficial nonwoven layers.The intensity of polyster fibre is high, and wearability is good, and has good chemical stability, under normal temperature, can not have an effect with weak acid, weak base, oxidant.
Further, described spandex fibre accounts for 9% ~ 17% in surperficial nonwoven layers.The elasticity of spandex fibre is excellent, and intensity is high, and line density is thin, and chemically-resistant degraded, and dry cleaning resistance, wearability are all better.
In sum, a kind of Novel filtration cloth that the present invention points out, compares with common filtration cloth, has increased the inner core that metallic fiber is made, and can prevent the Electrostatic Absorption of fine particle, keeps filtering the highly-breathable of cloth, and filter efficiency is high.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
