The utility model " the anti-needled filtering felt of terylene stripe three " of Authorization Notice No. CN 201572574U discloses the anti-needled filtering felt of a kind of terylene stripe three, is respectively stained with one deck polyster fibre mixing surface layer the upper and lower of polyester filament fiber blend base cloth.Advantage is continuous serviceability temperature is 130 DEG C, and serviceability temperature is 150 DEG C instantaneously; There is certain antistatic property, sheet resistance Ω < 10
7 ~ 9, volume resistance Ω < 10
7 ~ 9; Refuse water grease proofing effective, refuse water grade and reach 4-5 level; Physical and mechanical properties is high, and anti-wear performance is strong, long service life.
The endless tow that above utility model uses is traditional non-dispersive type, bonding agent need be relied on to carry out bonding, there is following shortcoming: the existence of (1) fiber filament bundle surface glue, have impact on interface cohesion; (2) density of fibrofelt is higher, not easily fluffy; (3) cost is higher.
Utility model content
The utility model, in order to solve the problem, provides the continuous decentralized filament fiber Nomex that a kind of porosity is high, low cost product, comprehensive serviceability are better.
The technical solution of the utility model is as follows: a kind of decentralized filament fiber Nomex continuously, is composited by the fluffy yarn sheet yarn of continuous filament yarn and staple fiber net; The fluffy yarn sheet yarn of described continuous filament yarn and staple fiber net replace lay, by doing upper and lower acupuncture campaign with the pricker of acicular hook, are thrust by the staple fibre in staple fiber net in the fluffy yarn sheet yarn of continuous filament yarn, form the interlayer mutually tangled between long and short fiber and connect; Total number of plies of described continuous filament yarn fluffy yarn sheet yarn and staple fiber net is no less than 3 layers;
Described continuous decentralized filament fiber Nomex thickness is 8mm ~ 200mm, and fabric width is 1200mm ~ 2200mm, grammes per square metre 200-500g/m
2;
Described continuous filament yarn fluffy yarn sheet yarn be the acupuncture of monofilament shape fluffy continuous filament yarn distributed fibers bundle be made into without latitude cloth; According to the lay direction of wherein continuous filament yarn distributed fibers bundle, described continuous filament yarn fluffy yarn sheet yarn can be 0 degree of direction continuous filament yarn fluffy yarn sheet yarn, 0 degree of direction adds the fluffy yarn sheet yarn of tilt angle direction continuous filament yarn; The fluffy yarn sheet yarn of the continuous filament yarn of equidirectional can be used, also the fluffy yarn sheet yarn of continuous filament yarn of different directions can mix use; Multi-direction continuous filament yarn fluffy yarn sheet yarn and staple fiber net alternately can form multi-direction multi-angle continuous decentralized filament fiber Nomex.
Described staple fiber net to be each to equally distributed length the be staple fiber of 50mm ~ 80mm is by carding, crossing stack, make through licker-in compacting again, and the thickness of described staple fiber net is 1mm-8mm;
The thickness of the fluffy yarn sheet yarn of described continuous filament yarn is 1mm-6mm;
Described continuous filament yarn fluffy yarn sheet yarn can be carbon fiber continuous filament yarn fluffy yarn sheet yarn, glass fibre continuous filament yarn fluffy yarn sheet yarn, PAN base oxidization fiber continuous filament yarn fluffy yarn sheet yarn or the fluffy yarn sheet yarn of chemical fibre continuous filament yarn; Described staple fiber net can be carbon fiber staple fiber net, glass chopped fiber web, PAN base oxidization fiber staple fiber net or chemical fibre staple fiber net; Usually, in the fibrofelt of same specification, the fluffy yarn sheet yarn of continuous filament yarn of identical type uses together with staple fiber net.
Beneficial effect
The utility model continuous decentralized filament fiber Nomex, be a kind of not containing the fibrofelt of any bonding agent, the multidirectional distribution of continuous filament yarn, it is by staple fiber net and dispersed continuous filament yarn sheet yarn compact siro spinning technology all-in-one-piece fibrofelt by needling action.Needled non-woven cloth technology based on dispersion long filament technology thickens technology with lamination acupuncture and combines, and forms multidirectional, high porosity fibrofelt.The utility model Nomex Stability Analysis of Structures, intensity is better, porosity is high, and mechanical property can design.Compared with allied fiber felt disclosed in prior art, the fibrofelt thickness obtained by the utility model preparation method is thicker, elasticity better, and made fibrofelt bulking intensity can improve 15%-50%; Porosity can improve 10%-40%.Due to the existence of decentralized endless tow, fiber microchannel is trickleer, is more conducive to resin infiltration, easier carburizing and deposition.Comparatively low-density, Stability Analysis of Structures can be obtained, the composite be evenly distributed.Owing to there is the decentralized long filament of multiple directions, fiber microchannel is more crisscross, is more conducive to resin infiltration, easier carburizing and deposition.Fiber consumption in product unit volume is less, and porosity is higher, and product cost is lower, and the heat insulating effect of product is better.The utility model solves long filament dispersion problem well, improves the porosity of fibrofelt, reduces product cost, gives the comprehensive serviceability that fibrofelt is more excellent.
