Abstract
The utility model discloses a terylene gradient-type spunlace felt, which is in a layered structure, wherein polyester fiber layers are symmetrically adhered onto the upper surface and the lower surface of terylene base cloth respectively; and each polyester fiber layer is formed by polyester fiber layers with different specifications. The terylene gradient-type spunlace felt disclosed by the utility model has the advantages of high physical mechanical property, high filter precision, easiness for removing ash, small running resistance, energy source conservation and long service life.
Description
Technical field
The utility model relates to water thorn felt; Particularly a kind of terylene ladder degree water thorn felt; This material can be used for the filtering material of flue gas and treating flour dust, and the utility model also relates to a kind of production technology of terylene ladder degree water thorn filter felt simultaneously, belongs to the production technology development technical field of filtering material.
Background technology
At present, the filtrate of sack cleaner is many to be main with acupuncture, needling process be with the product development class extensively, the process means comprehensive advantage leading position in the nonwoven manufacturing technique always flexibly.Yet; Because acupuncture is the pricker with the buckle of rigidity thorn to move back and forth in fibre web and making between the fiber each other that entanglement forms cloth; Inevitable during the damage that in the acupuncture course fiber and base cloth caused, and needle fabric often has pin trace, Boardy Feeling, surface problems such as fracture shape is arranged.For some high density, high-quality eedle-punched non-wovens, possible these problems seem even more serious, and product strainability and service life after the making are still not ideal enough.
The utility model content
The technical problem of the utility model provides a kind of filtrate service life of can improving, and filter efficiency is high, and physical and mechanical properties is high, the terylene ladder degree water thorn felt of cost economy.
In order to solve above technical problem, the utility model provides a kind of terylene ladder degree water thorn felt, and this water thorn felt is a layer structure, the symmetrical respectively polyster fibre layer of pasting in the top and bottom of terylene base cloth.
Described polyster fibre layer is made up of the polyster fibre layer of different size.
The superior effect of the utility model:
1) Physical Mechanical is high;
2) high, the easy-to-clean ash of filtering accuracy;
3) running resistance is little, saves the energy;
4) high life.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Label declaration among the figure:
1-polyster fibre layer; 2-terylene base cloth.
The specific embodiment
Below in conjunction with Fig. 1 and specific embodiment the utility model is at length explained.
The utility model provides a kind of terylene ladder degree water thorn felt; This water thorn felt is a layer structure, in the top and bottom of terylene base cloth 2, under the double action of the direct impact of high pressure liquid drugs injection and reflection liquid drugs injection; Inject polyster fibre layer 1, form fibre web and the base cloth composite construction that closely tangles.Compare with needling process, the flexibility of water jet process is tangled and is made the base cloth in the composite filter material be enhanced with the intensity of fiber, thus the brute force of raising final products.This polyster fibre layer 1 is made up of the polyster fibre of different size, with the conventional polyester procedure of processing similar different be that the fiber of its different size forms different separately fibrage and then from coarse to fine successively and in layer is superimposed together.
The utility model is dropped into actual operating mode use, through implementing proof, the continuous operation temperature of the utility model is 130 ℃ ~ 150 ℃; Brute force>=1000N/5 * 20 ㎝ radially, broadwise brute force>=1300N/5 * 20 ㎝, radial fragmentation percentage elongation≤30%; Broadwise elongation at break≤50%, air permeability 10m
3/ m
2Min improves 12% service life.
