Preferably, the supporting layer forms smooth outer surface by processing of singing.
Preferably, the depth of needling of the supporting layer is 3-5mm, to realize the stronger support strength of supporting layer.
Preferably, the angle stripper range of speeds in the carding machine of the supporting layer is manufactured in 400-500r/min scopes Interior, the rotating speed of working roll is in the range of 80-100r/min;The angle stripper pin tooth and cylinder cross-over configuration;The carding machine is adopted With double blessing cross lapping modes, speed is in the range of 80-120m/min.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that:
1. the utility model patent is by carefully studying terylene and acrylic blending rate and on networking process is combed Research, and pass through the research in actual production to needling process.There is filtering so as to reach the filter felt developed The advantages of precision is high, Air permenbility is small, good stability of the dimension, strength are big and mechanical property is good.
Brief description of the drawings
Fig. 1 is structure diagram of the present utility model;
Fig. 2 is that polyester fiber and acrylic fiber comb structural representation into the net.
In figure:1- meets knoisphere;2- base cloth layers;3- supporting layers;4- enhancement layers;21- polyester fibers;22- acrylic fibers.
Embodiment
The utility model is described further with specific embodiment below.
Embodiment one:As shown in figure 1, a kind of terylene acrylic blending needled filtering felt, including meet knoisphere 1, the and of supporting layer 3 It is arranged on and meets base cloth layer 2 between knoisphere 1 and supporting layer 3, the knoisphere 1 of meeting is handed over by polyacrylonitrile fibre and acrylic fiber 22 Mistake, which is tangled, to be formed;The fiber mesh cloth that the supporting layer 3 is acrylic fiber and viscose-based carbon fiber blending forms;The base cloth layer 2 It is the filtering base fabric formed by polyester fiber 21 and acrylic fiber 22 by combing networking process blending;It is described to meet knoisphere 1, base Layer of cloth 2 and supporting layer 3 mutually link reinforcing by using the trilobal cross acupuncture of bulb needle point and are integrated, described to meet the top of knoisphere 1 Enhancement layer 4 is provided with, enhancement layer 4 is that polytef flocks and polyphony thioether short fiber plant pin warp using random cloth pin mode Comb, the network structure that the entanglement of lapping technique forms.The utility model patent is by carefully studying terylene and acrylic blending ratio Example and the research on networking process is combed, and pass through the research in actual production to needling process.Ground so as to reach Making the filter felt come has the advantages of small filtering accuracy height, Air permenbility, good stability of the dimension, strongly big and mechanical property is good. Enhancement layer 4 described in the utility model sufficiently make use of the physical property of polytef flocks and polyphony thioether short fiber The characteristics of stable corrosion-resistant and high-temperature resistant, by increasing capacitance it is possible to increase meet the intensity in the place face of knoisphere 1, the energy of opposite complex working condition can be increased Power.
Preferably, the weight proportion of polyester fiber 21 on the base cloth layer 2 is 0.8-1.4:1.Such weight proportion compared with Prior art is more reasonable, particularly when in face of complex working condition, can give full play to the intensity of polyester fiber 21 height, bullet Property is good, thermoplasticity is good, corrosion resistant feature.Alleviate that polyester material Boardy Feeling, sense of touch are poor, gloss is not soft to a certain extent again With, gas permeability, hygroscopicity difference the shortcomings of.It is preferably to design counterweight compared with prior art.
Preferably, the weight proportion of the acrylic fiber 22 on the base cloth layer 2 is 0.9-1.1:1.Such weight is matched somebody with somebody Compare that prior art is more reasonable, particularly requiring heat resistance, decay resistance higher operating mode practicality more preferably, The good resistant to elevated temperatures performance of acrylic fiber 22 can be given full play to, while is also had in wearability and corrosion resistance good Performance.It is the preferable design counterweight in actual production operation.
Preferably, the polyacrylonitrile fibre met on knoisphere 1 is formed by fiber filament braiding, and with the acrylic Fiber 22, which intersects, combs networking, to ensure product in the uniformity on direction in length and breadth.The technical program is to combing networking work Designed in sequence, by the design of this technology originating party case, the service life for the increase filtrate that can be optimized, obtain unit plane The web of product uniform quality, shapes by pinprick reinforcement, thus farthest service life can be optimized.
Preferably, the filament diameter of the acrylic fiber on the supporting layer 3 is 10.5-11.5 μm, and the viscose glue base carbon is fine The filament diameter of dimension is 10.5-11.5 μm.So filament diameter is can farthest to realize supporting layer 3 to whole filter felt Supporting role.So as to which further aid filter felt has the performances such as good mechanical property and processing and forming.
Preferably, the supporting layer 3 forms smooth outer surface by processing of singing.Processing of singing is mainly used in dust Or the non-woven material of siccative filtering, the filoplume of its protrusion of surface is burnt up, is allowed to that surface is brighter and cleaner, and filter effect is more preferable.
Preferably, the depth of needling of the supporting layer 3 is 3-5mm, to realize the support strength of supporting layer the last 3.This The depth of needling of sample can farthest reduce the injury to fiber in acupuncture course, be the preferable acupuncture of the utility model Depth.
Preferably, the angle stripper range of speeds in the carding machine of the supporting layer 3 is manufactured in 400-500r/min scopes Interior, the rotating speed of working roll is in the range of 80-100r/min;The angle stripper pin tooth and cylinder cross-over configuration;The carding machine is adopted With double blessing cross lapping modes, speed is in the range of 80-120m/min.
It is explained as follows for preferably displaying product structure, spy:
In order to obtain can filtering accuracy is high, Air permenbility is small, good stability of the dimension, the filtering that strength is big, mechanical property is good Felt, the technical program pass through one by the research to the blending ratio of terylene acrylic fiber 22, fibre carder skill and needling process It is individual to optimize setting to realize function above.Technical solutions of the utility model use terylene as base fabric, then coordinate acrylic fine Dimension 22 forms according to certain blending ratio blending and is used as base fabric to design.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection model of the present utility model according to this Enclose, therefore:All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model Within the scope of.
