Description

Woven knitting composite construction based high-temp-resistant environmental protection filtrate of one kind and preparation method thereof
Technical field
The invention belongs to filter with separation material field, more particularly, to a kind of woven knitting composite construction Ji Naigao Warm environmental protection filtrate and preparation method thereof.
Background technique
Sack cleaner is a kind of dry type dust filtration device, and the main filtration using fabric is to subtle, drying Dust is captured, and is able to satisfy emission request, harmless effect to reach filtered air.Existing heat resistance filter bag one As use using fibers such as P84, PPS, PTFE, aramid fiber, basalt, glasses as raw material, using nonwovens process, pierce and process through needle It forms, pricker is all made of triangle, trifoil cross-section.In order to enhance the strength of filtrate, have among filtrate woven or knitting Base fabric.The strength of filtrate is provided jointly by surface layer fibre web and base fabric, and the contribution rate of strength respectively may be about 30% and 70%.
Filtrate is during pinprick reinforcement, with the high speed reciprocating motion up and down of pricker, needle point and barb impact base fabric and The short fibre of fibre web leads to fibrous fracture or damage, and filtrate strength declines, and service life significantly reduces.
Summary of the invention
The purpose of the present invention is overcoming the above deficiency, provide a kind of woven knitting composite construction based high-temp-resistant environmental protection filtrate and Preparation method, utilization is woven, is knitted the structural stability and suitable type of compound base fabric, and oval pricker is to the damage of base fabric Hurt lesser characteristic and prepare high-tenacity, high temperature resistance filtration material, extends the service life of filtrate.
To achieve the goals above, the present invention provides a kind of woven knitting composite construction based high-temp-resistant environmental protection filtrate, including The woven knitting composite construction base fabric as made of knitted structure and machine-knitted structure braiding, it is woven to be knitted the upper and lower of composite construction base fabric Surface is laid with composite fibre net, and the surface of the composite fibre net of any one side is equipped with micro porous filtration membrane coat.
The knitted structure of woven knitted composite material base fabric of the present invention is that stocking yarn uses plain stitch, double rib group It knits or rib construction；The machine-knitted structure is that warp thread and weft yarns form.The stocking yarn, warp thread and weft yarn are inorfil High-performance fiber Single Fiber or two kinds of fibers composite fibre yarn.The preferred glass of the inorfil or basalt are fine Dimension, the preferred P84, PPS of high-performance fiber, PTFE, aramid fiber.
Woven knitting composite construction base fabric density of the present invention is 50-250g/m2, preferably 100-250g/m2。
Composite fibre net of the present invention is to cross interleaved mode multilayer by single layer fibre Netcom to be paved into, the composite fibre net Density be 100-300g/m2, preferably 100-250g/m2, the single layer fibre reticular density is 15-25g/m2。
Filtrate of the present invention is with a thickness of 1.5-3.0mm, density 250-600g/m2, preferably 300-600g/m2。
The preparation method of woven knitting composite construction based high-temp-resistant environmental protection filtrate of the present invention, is by fiber spun yarn Afterwards, weaving is at woven knitting composite construction base fabric；The composite fibre net point that fiber is formed through mixing, combing, lapping, pre-needling Be not laid on the upper and lower surface of composite construction base fabric, with oval pricker to base fabric and web carry out pinprick reinforcement carry out again it is whole Reason is prepared.
Woven knitting composite construction base fabric is by the plain stitch using stocking yarn braiding, interlock described in the above method Or the knitted structure and use warp thread of rib construction and the plain woven structure of weft yarns weave.The yarn of use be by Fiber is made through cotton carding, at item, rove, spinning process.
Fiber described in the above method be one or both of inorfil or the short fibre of high-performance fiber fiber by grab cotton, Shredding, the silvalin being mixed or basaltic buiky yarn.The fiber inorganic fiber or the short fibre of high-performance fiber, are adopted The short fibre for being 30-90.0mm with 1.2-9D, length, basalt fibre select zero twisted yarn, twisted yarn or rove.Wherein, silvalin The line density of line selects twisted yarn, line density 150-300dtex, twist 35- in 3-10dtex, basalt yam stocking yarn 50 twirls/50cm, basalt warp, weft yarn select rove, line density 600-2400dtex.
Pre-needling condition described in the above method are as follows: bestock: 1250 pieces/m, needling density 800-840 Ci/㎝2, needle Pierce depth 11mm, web velocity 4m/min.
The condition of the thorn of needle described in the above method are as follows: needling density 210-2000 thorn/cm2, depth of needling 7-13mm, plant needle 1000-3000 pieces of density/m, web output speed 0.5-2.5m/min.Pricker used has two ribs, on every rib there are two Briar tooth, briar tooth are spaced with briar tooth.
Arrangement described in the above method is to singe, be formed and coating；Wherein, singing is the short and small fibre for removing filter material surface Dimension, sizing mainly improve the thermal stability of filtrate, and coating is to coat micro porous filtration membrane coat in fabric surface, enhances filtrate Filter efficiency.The coating can be that (aperture is for PTFE ultrafiltration membrane coat (aperture be 0.01~0.1 μm) or ceramic membrane coat 0.8nm~1 μm).
It is above-mentioned it is woven knitting composite construction based high-temp-resistant environmental protection filtrate preparation method specifically includes the following steps:
(1) composite fibre net is made through combing, lapping and pre-needling process in fiber；
(2) yarn is made through cotton carding, at item, rove, spinning process in fiber；Yarn uses plain group as stocking yarn Knit, interlock or rib construction are knitted structure, yarn, using plain woven structure, is woven into machine as warp thread and weft yarn Weaving knitting composite structure base fabric；
(3) layer tiles composite fibre net respectively in woven knitting composite construction base fabric, acupuncture apparatus is transported to, by planting Filtrate is made in the upper and lower reciprocal pinprick reinforcement of oval pricker high speed on needle plate；
(4) filtrate is by singing, being formed and coating obtains final products.
The filtrate of above method preparation is with a thickness of 1.5-3.0mm, weight 250-600g/m2, vertically and horizontally ultimate strength 900- 1600N/5cm, Air permenbility 100-200L/dm2·min。
Compared with prior art, the invention has the benefit that
(1) woven knitting compound base fabric is a kind of new structure (CWK) fabric, wherein existing mutually handed over by warp thread and weft yarn Knit the machine-knitted structure to be formed, and have by stocking yarn bending into coil, and mutually wear and the knitted structure that is formed, be two kinds of knots Structure it is compound.Base fabric of the present invention has merged woven and knitting technology simultaneously, and base fabric is made to have structural stability and suitable type.
(2) oval pricker cross section in same needle thorn diameter is maximum, wink when pricker pumps, with base fabric Between contact most mild, the damage of base fabric and short fibre of non-woven layer is less, strongly than same fiber, specification filtrate of the same race raising 10% or more.It can prolong the service life.
(3) fiber environmental that uses of the present invention and can Wear-resistant, high-temperature resistant, short fibre is also beneficial to avoid being needled damage.
