Abstract
The invention provides a polyphenylene sulfide fabric and a purpose thereof. The fabric is made from polyphenylene sulfide monofilaments with fineness of 4-500 dtex; the average pore size of the fabric is 0.5-50 microns. The polyphenylene sulfide monofilaments are made by using a fiber splitting technology. The polyphenylene sulfide fabric provided by the invention has the advantages of light, thin and soft texture, high density and low pore size and can be applied to the preparation of precise high temperature filtering clothes.
Description
Technical field
The present invention relates to a kind of polyphenylene sulfide fabric, be specifically related to a kind of top-weight fabric by the thinner formed low aperture of polyphenylene sulfide filaments of fineness and uses thereof.
Background technology
At present, the main existence form of polyphenylene sulfide fibre goods has staple fibre on the market, long filament, brachymemma fiber and processed goods woven fabric thereof, knitted fabric, nonwoven fabric felt, paper products etc.The woven woven fabric of monofilament also has certain applications in paper grade (stock) net field.Polyphenylene sulfide fibre mainly is widely used in the gas filtration field with its excellent high temperature resistant and chemical-resistance; Wherein mainly comprise the fabric that staple fiber batt and staple fibre yarn and long filament are made into, and high-precision polyphenylene sulfide filaments fabric with and do not appear in the newspapers as yet in the application of filtration art.
Reason is, the polyphenylene sulfide filaments of passing through traditional monofilament spining technology Direct Production that exists in the market, and its fineness specification limit is about 500dtex, and the spinning engineering of the thin monofilament below the 500dtex is extremely difficult.Therefore, can't realize utilizing the less monofilament of fiber number to weave low aperture, high accuracy, the technology of cloister fabric.
TOHKEMY 2010-126838 discloses a kind of polyphenylene sulfide filaments, its manufacturing approach and industrial fabric.Provide in this invention and utilized this monofilament of at least a employing is produced in polyphenylene sulfide filaments that the monofilament production technology produces and warp thread or the weft yarn surface smoothing property industrial fabric preferably; Be applicable to conveyer belt; The paper grade (stock) net, general industrial purposes such as filtering material.This polyphenylene sulfide filaments obtains through traditional monofilament production technology spinning, and the monofilament fineness and the production efficiency of gained all are restricted, and can not be used to process the fabric in low aperture, use filter cloth so just can not be used to prepare accurate high temperature filtration.
Summary of the invention
The object of the present invention is to provide a kind of frivolous, soft, high density, the polyphenylene sulfide fabric in low aperture and uses thereof.
Technical solution of the present invention is following:
A kind of polyphenylene sulfide fabric, this fabric are that the polyphenylene sulfide filaments of 4～500dtex is made by fineness, and the average pore size of this fabric is 0.5～50um; Said polyphenylene sulfide filaments utilization divides fine technology to make.
Above-mentioned fineness is that the polyphenylene sulfide filaments of 4～500dtex is through general polyphenylene sulfide multifilament being adopted hand divide fibre or equipment to divide the fine technology of fine branch to make.The conventional method of spinning polyphenylene sulfide filaments is directly to spin through the single hole spinnerets at present, yet the monofilament fineness that this method makes receives the restriction of spinning process condition, and the monofilament fineness great majority are more than 500dtex, and production efficiency is low.Because the spinning process of multifilament can not only improve spinning speed, more can promote production capacity by the difference of spinning hole number.The raising of spinning speed increases except production capacity, also can increase fibre strength.According to present multifilament production technology, the fineness of individual thread can carefully reach 1.0dtex in the polyphenylene sulfide multifilament of production.
The thickness of fabric is very big with the monofilament fineness relation of forming fabric, and the monofilament that fineness is thinner makes low aperture, light and thin type fabric especially easily.But in technology of the present invention, if the monofilament fineness of polyphenylene sulfide less than 4dtex, then easy fracture of wire causes the fine process difficulty of branch; If monofilament fineness is greater than 500dtex, then coiling and molding is bad, and the engineering trafficability characteristic is poor.Preferred 10～the 100dtex of the monofilament fineness of using among the present invention.
Polyphenylene sulfide filaments fabric of the present invention, its fabric average pore size is 0.5～50um.When weaving; The size in fabric aperture should require according to the purposes of this fabric to adjust, if when requiring less than 0.5um to the aperture of fabric, then Density is too high; Because of friction between monofilament frequently is prone to cause the monofilament fracture of wire, just like this weave difficulty in the weaving process; The fabric aperture is during greater than 50um, is prone to cause in the fabric each monofilament to cross between rare monofilament because of the density of fabric and slides relatively easily, and the fabric moulding is bad, and the situation of poor dimensional stability takes place.The average pore size of polyphenylene sulfide fabric of the present invention is preferably 5～30um.
Above-mentioned polyphenylene sulfide filaments utilization divides fine technology to make; That is to say the further polyphenylene sulfide filaments through adopting hand to divide fibre or equipment to divide fine technology to make of polyphenylene sulfide multifilament that conventional method is made, this has not only realized making the technology of fine denier polyphenylene sulfide filaments.Simultaneously, for the PPS monofilament that the direct fabrics mode is produced, production efficiency improves, and the cost slip increases.
The raw material that above-mentioned polyphenylene sulfide filaments adopted is the polyphenylene sulfide polymer of weight average molecular weight 30000～60000.If adopt molecular weight to carry out melt spinning less than 30000 polyphenylene sulfide polymer; The viscosity of melt spinning liquid is low, and spinning tension is low, and fracture of wire takes place in spinning process easily; Cause spinning process significantly to worsen, and the mechanical property of the polyphenylene sulfide fibre that obtains is relatively poor; If adopt molecular weight to carry out spinning greater than 60000 polyphenylene sulfide polymer, because of the viscosity of melt spinning liquid is high, need have special high voltage bearing spinning equipment, can cause the manufacturing equipment cost too high.
Adopt above-mentioned polyphenylene sulfide polymer to make the polyphenylene sulfide multifilament, contain 4～40 polyphenylene sulfide filaments in the multifilament of gained through composite spinning.If the monofilament radical, can cause the fine difficulty of branch greater than 40, be entangled with winding mutually; If the monofilament radical less than 4, will cause production efficiency low excessively, the engineering trafficability characteristic is poor.Preferred monofilament radical is 6～20.
The tensile break strength of above-mentioned polyphenylene sulfide filaments is 2～10cN/dtex.If the tensile break strength of monofilament is during less than 2cN/dtex, filament strength is low excessively, bears and incessantly divides fine tension force, causes the generation of fracture of wire phenomenon easily; If the tensile break strength of monofilament is greater than 10cN/dtex; Adopt the higher polyphenylene sulfide polymer of weight average molecular weight to carry out spinning with regard to requiring; Because of the viscosity of melt spinning liquid is high, need have special high voltage bearing spinning equipment, can cause the manufacturing equipment cost too high.Tensile break strength 4～the 8cN/dtex of preferred polyphenylene sulfide filaments.
Polyphenylene sulfide fabric of the present invention have frivolous sense well, soft, advantage such as density is high, the aperture is low.Can be applicable to prepare accurate high temperature filtration and use filter cloth, the accurate high temperature filtration that specifically is applied to gas or liquid is used filter cloth, both can reach high efficiency filter, the effect that can reach a high temperature again and filter.
