Abstract
The utility model discloses a polyester fiber spunlaced non-weaving cloth filtering felt which adopts the structure that polyester fibrous layers are symmetrically pasted on the upper surface and the lower surface of polyester fabric. Compared with the prior art, the polyester fiber spunlaced non-weaving cloth filtering felt has the following advantages that firstly, polyester fiber is taken as raw material, the raw material has good physical and chemical properties, structure, and technological adaptability of web formation and reinforcement, and can adapt to the high-speed and efficient carding production, and the entanglement result of the spunlaced non-weaving cloth to the fiber is improved, so that the mechanical strength of the spunlaced compound filtering material is obviously improved, the end products are ensured to have good mechanical properties, filtration performance and dimensional stabilities; secondly, the conventional filtering material is processed through acupuncture, the polyester fiber spunlaced non-weaving cloth filtering felt is processed through the spunlaced process, and after high-pressure spray cutter penetrates a fiber web and the fabric, and a structure that the fiber web and the fabric are closely entangled and compounded is formed. The strengths of the fabric and the fiber in the compound filtering material are greatly improved by virtue of flexible entanglement, so that the filtration performance of the end products is improved.
Description
Technical field
The utility model relates to a kind of filtering material, particularly a kind of filtering material that is used for flue gas and treating flour dust, and the utility model also relates to a kind of terylene water thorn combined filtration felt simultaneously.
Background technology
At present, the filtrate of sack cleaner is many based on 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 mutually 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
For solving foregoing problems, the utility model provides a kind of structure of this felt of polyster fibre water thorn filter felt to be,
At the upper and lower surface of terylene base cloth, at the upper and lower surface of terylene base cloth, use the high-pressure water jet machine, symmetrical water thorn is pasted the polyster fibre layer.
Described terylene base cloth is the woven cloth of polyester filament.
The utility model has the following advantages compared with prior art: first, the employing polyster fibre is a raw material, the Technological adaptability of the physicochemical property of this raw material self, structure, one-tenth net and reinforcing is better, can adapt to the high-speed and high-efficiency combing produces, improve the entanglement effect of water thorn to fiber, the mechanical strength that is water thorn composite filter material is significantly improved, and guarantees that final products have favorable mechanical performance, strainability and dimensional stability; The second, traditional filtering material all is to adopt acupuncture processing, and this product adopts water jet process processing, behind water under high pressure needle penetration fibre web and the base cloth, form bounce-back in drum surface, under the double action of the direct impact of liquid drugs injection and reflection liquid drugs injection, 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 and the intensity of fiber be enhanced, thereby improves the brute force of final products.The complete compound GB of this product:
(1) mass area ratio: 550g/m2;
(2) thickness: 1.37 mm;
(3) powerful characteristic (N/5 * 20cm): vertically: 1100, laterally: 1700
(4) elongation characteristics (%): vertically: 21.3, laterally: 25.8;
(5) air permeability (m3/m2min): 3.8
Serviceability temperature: 120 ℃ ~ 150 ℃
This non-woven filter material is widely used in industry dust removal and filtrations such as cement plant, incinerator, coal-burning boiler, power plant, chemical plant, steel plant.
