Abstract
The utility model discloses a high-efficiency and low-resistance non-woven filter material. According to the filter material, filament fibers are taken as spinning raw materials to be manufactured into a spun bonded filament mesh as a framework, a short fiber layer is spread on the spun bonded filament mesh surface to form a filtering surface, and the filter material is prepared through high pressure repeatedly by a wspunlaced machine. The filter material has the advantages that the short fibers are firmly fixed on the surface of the long filament fiber mesh, the specific surface area of non-woven fabric is increased, not only excellent mechanical performance of the filament non-woven fabrics is achieved, but also excellent filter effects of short fibers are realized, and the technical limitation that only short fibers are used in high efficiency filter material is broken through.
Description
Technical field
The utility model relates to a kind of non-woven filter material, designs a kind of efficient low-resistance non-woven filter material that is used for the environmental protection field especially.
Background technology
At present, machine oil, engine, filter cartridge dust remover etc. on the market adopts traditional filter paper to filter, and this filter paper is to adopt wet therapy forming process, and main component is that string or string and glass fibre are compound in the filter paper.The waste water that this technology is come out is many, and waste water is difficult to handle, and is bigger to plant demands such as trees, is unfavorable for environmental protection; And there are defectives such as ultimate strength is low, strainability is general, service life is short in product.
The utility model content
Technical problem of the present utility model mainly provides a kind of efficient low-resistance non-woven filter material that replaces conventional filter paper.
In order to solve above technical problem, the utility model provides a kind of efficient low-resistance non-woven filter material, it is skeleton that this filtering material is made the spun-bonded continuous yarn net with filament fiber as the spinning raw material, the layer overlay short fiber layers forms filtering surface on this spun-bonded continuous yarn wire side, is pressed into through spun-laced machine is repeatedly high.
Described spun-bonded continuous yarn net adopts a kind of in high polymer terylene PET, nylon PA6, polypropylene fibre PP, the polyphenylene thioether PPS or two kinds as raw material.
Described short fiber layers is that a kind of in PET fiber, devillicate, ultra-fine polyphenylene thioether PPS fiber, ultra-fine polytetrafluoroethylene PTFE fiber, the ultra-fine aramid fiber or two kinds are as raw material.
The beneficial effects of the utility model are: the efficient low-resistance non-woven filter material of the replacement conventional filter paper that forms by this technology, short fiber is fixed on the surface of filament web firmly, increase the specific area of nonwoven, existing filament nonwoven cloth favorable mechanical performance, the filter effect that the short fiber excellence is also arranged, having broken through the high efficiency filter material can only be with the technical limitations of short fiber.Simultaneously can also be according to the polytropy of spun-bonded continuous yarn specification; after forming slim spunbond net; compound with short fiber again; through after the functionalization; make product to recycle; to substitute traditional filter paper, can effectively alleviate the situation of the in short supply and import pulp anxiety of China's timber, significant for protection environment, comprehensive utilization of resources, minimizing carbon emission.
Description of drawings
Fig. 1 is product structure figure of the present utility model;
The number in the figure explanation
1-spun-bonded continuous yarn net; 2-short fiber layers.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
The utility model provides a kind of efficient low-resistance non-woven filter material, it is skeleton that this filtering material is made spun-bonded continuous yarn net 1 with filament fiber as the spinning raw material, layer overlay short fiber layers 2 forms filtering surfaces on 1 on this spun-bonded continuous yarn net, is pressed into through spun-laced machine is repeatedly high.
Described spun-bonded continuous yarn net 1 adopts a kind of in high polymer terylene PET, nylon PA6, polypropylene fibre PP, the polyphenylene thioether PPS or two kinds as raw material.
Described short fiber layers 2 is that a kind of in PET fiber, devillicate, ultra-fine polyphenylene thioether PPS fiber, ultra-fine polytetrafluoroethylene PTFE fiber, the ultra-fine aramid fiber or two kinds are as raw material.
Spunbond net process: the PPS section is dry earlier, carry out fusion by screw extruder then, through behind the melt filtration, enter in the filament spinning component and go, by spinneret ejection PPS fiber, through cooling quench, with the air drawing of 500m/min, on lapper, be paved into 100-400g/m
2The PPS filament web; Short fiber net process: ultra-fine PPS short fiber through shredding, feeding, combing, is formed 50-200g/m on high speed lapping machine
2The PPS web of staple fibers enters PPS short fiber fleece and filament web simultaneously the high pressure spun-laced machine then and carries out the water under high pressure thorn and reinforce, drying, functionalization post processing, cut, rolling, finished product.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
