In the past, as dust-collecting bags for electric dust cleaners, proposed to use dust bag (opening flat 6-48556 communique in fact) by inner bag and the double-deck filter paper of outer bag.But when using this filter paper, in order to capture mould and fine dust such as pollen, the order that must increase paper is paid (weight per unit area), and the result exists the problem of pressure loss increase.
In addition, be purpose to improve dust collection efficiency, the dust bag (for example, the spy opens flat 2-116338 communique, No. 3019283 communique of utility model etc.) of inner bag use nonwoven has been proposed.But the moisture that these dust bags in use replenish can cause broken bag, exists the shortcoming of the function that loses dust bag.
In order to solve this problem, it is stacked and form the scheme (spy open 2000-195 communique) of the fibre sheet material of one as the dust-collecting bags for electric dust cleaners of outer bag usefulness for example to have proposed enhancement Layer that the filter course that is formed by melt spraying non-woven fabrics and Wet-laid non-woven fabric are formed.But this dust-collecting bags for electric dust cleaners be because melt spraying non-woven fabrics and Wet-laid non-woven fabric bonding firm inadequately cause splitting so understand in using between the two, and its result can not make full use of the ability of the good capture dust of melt spraying non-woven fabrics.And, when inhaling the minimum dust of particle diameter, easily causing plug-hole, concerning the dust suction performance, can not meet the demands.
Summary of the invention
The object of the present invention is to provide a kind ofly by the dust catcher dust bag, this dust collecting sleeve can address the above problem, and has low pressure loss and high arresting efficiency that existing dust-collecting bags for electric dust cleaners can not fully reach, and, be difficult for producing the broken bag phenomenon during use.
The present inventor is for solving the result that above-mentioned problem is inquired into repeatedly with keen determination, discovery configuration on the one or both sides with melt spraying non-woven fabrics that specific order pays contains the Wet-laid non-woven fabric of specified quantitative vinylal fibre, the fibre sheet material that disposes the stepped construction of this Wet-laid non-woven fabric is used as outer bag, can solve above-mentioned problem, reach purpose of the present invention.
Promptly, the present invention is the dust-collecting bags for electric dust cleaners with inner bag and outer bag, outer bag be use by diameter be the melt spraying non-woven fabrics that constitutes of the fiber below the 10 μ m and on its one or both sides the stacked integrally formed order of Wet-laid non-woven fabric that contains 40% above vinylal fibre pay and be 35-80g/m
2Fibre sheet material make.
Dust catcher dust bag of the present invention, because adhesion strength is enough big, so in use or in the processing and forming can not produce the splitting phenomenon, and the equalization performance of the pressure loss and arresting efficiency is good, pretend to dust-collecting bags for electric dust cleaners is to have high performance dust bag, and can provide to the consumer at an easy rate.In addition, dust-collecting bags for electric dust cleaners of the present invention also can capture expeditiously to the minimum dust of particle diameter, is difficult for stopping up.
The specific embodiment
Below, the present invention is specified.
Dust-collecting bags for electric dust cleaners of the present invention is made of an inner bag and an outer bag double-decker, and outer bag uses fibre sheet material very important, and this fibre sheet material is that melt spraying non-woven fabrics and the Wet-laid non-woven fabric that contains vinylal fibre are laminated.
Constitute the polymeric material of the used melt spraying non-woven fabrics of one deck of fibre sheet material of outer bag of dust-collecting bags for electric dust cleaners of the present invention, for example so long as the polyolefin of polypropylene, polyethylene and so on, polyester such as PETG or polybutylene terephthalate, nylon 6, the thermoplasticity polymer of nylon 66 polyamide such as grade and so on gets final product, it or not the special material that limits, but from the viewpoint of commodity is provided to the consumer at an easy rate, preferably by polyolefin, the melt spraying non-woven fabrics particularly made by polypropylene.
In addition, in the scope that does not influence effect of the present invention, medicaments such as antiseptic, mould inhibitor are added in this thermoplasticity fiber, make and carry out back after the nonwoven again and process also harmless.
Constituting the filamentary diameter of this melt spraying non-woven fabrics, from improving the viewpoint of arresting efficiency, to be advisable below the 10 μ m, is that 5 μ m are with next better.But too for a short time the tending to of fibre diameter produces the problem that pressure increases, so be preferably more than the 1 μ m.The order of this melt spraying non-woven fabrics is paid and is preferably 3-30g/m
2, be 5-20g/m
2Then better.Order is paid above 30g/m
2The time, the pressure loss increases, and the attraction of dust catcher is reduced.In addition, order is paid less than 3g/m
2The time, arresting efficiency tends to reduce.In order to bring into play better arresting efficiency, order is paid and is 5-10g/m
2Especially good.This melt spraying non-woven fabrics can be made with general melt blown technology, promptly, the thermoplasticity polymer of regulation is heated to more than the fusion temperature, extrude from nozzle and form strand, and then make and add hot-air from the ejection of the periphery of polymer nozzle bore, the limit makes that strand attenuates, the limit traps it on woven wire.
It is very important being laminated in the vinylal fibre that the Wet-laid non-woven fabric on the one or both sides of this melt spraying non-woven fabrics contains more than 40%.The use amount appropriateness of this vinylal fibre just can give Wet-laid non-woven fabric enough intensity, so can play the effect of the mechanical strength that strengthens melt spraying non-woven fabrics.And, when melt spraying non-woven fabrics and Wet-laid non-woven fabric are stacked, can give and enough adhesion strengths, so when using, also can prevent to produce the shortcoming of splitting as dust bag.Particularly in the present invention, this Wet-laid non-woven fabric preferably closes the polyethenol series viscose fibre of 7-20% and the polyethenol series main fibre of 30-80%.
The amount of polyethenol series viscose fibre is very little the time, and the insufficient strength of Wet-laid non-woven fabric, not enough with the cohesive force of melt spraying non-woven fabrics is measured when too many, tends to produce arresting efficiency and reduces, and be unfavorable for the shortcoming of cost.From arresting efficiency and the viewpoint favourable with the adhesion strength both of melt spraying non-woven fabrics, the polyethenol series viscose fibre of cooperation is preferably 7-20%, for 10-15% then better.
The polyethenol series main fibre that the present invention uses is preferably 30-80%, mixes then better in the scope of 50-75%.The blending ratio of this polyethenol series main fibre is lower than at 30% o'clock, is difficult to obtain enough intensity, otherwise, if surpass at 80% o'clock, often be difficult to the blending ratio of viscose fibre is remained on desirable value.The present invention uses the advantage of polyethenol series main fibre to be, can improve the intensity of dust bag under the situation that does not increase air permeance resistance.Promptly, use polyethenol series viscose fibre and polyethenol series main fibre simultaneously, can not tie the space that forms appropriateness on the cloth in resulting wet type, so can make the dust bag that air permeance resistance is little, intensity is high, and, when inhaling the very little dust of particle diameter, can bring into play better effect.
Among the present invention, the polyethenol series viscose fibre is the fiber in the water that is dissolved in below 80 ℃, and preferably basicity is less than 99.5 moles of fibers below the %.In addition, the polyethenol series main fibre preferably is insoluble in the water below 90 ℃, basicity is 99.9 moles more than the %.And this polyethenol series main fibre preferably carries out the acetal processing.The acetal degree is that 15-40 mole % is more satisfactory, and % is then better for the 25-35 mole.The degree of polymerization of the polyvinyl alcohol that any fiber constitutes is that 1000-2500 is more satisfactory.
The manufacture method of the vinylal fibre that the present invention uses can be with known method, adopts in wet type spin processes, dry-and wet-type spin processes, the dry spinning method any to get final product.
Because the vinylal fibre used of the present invention is to use as Wet-laid non-woven fabric, so its fineness is preferably 0.3-10dtex, for 0.5-5dtex then better.Block length and be preferably 1-20mm, for 2-10mm then better.The fineness of this vinylal fibre and block length if outside above-mentioned scope, then fiber often disperses bad during fabrication.
Among the present invention, even use the polyolefin polymer at melt spraying non-woven fabrics, especially using polyacrylic occasion, because the content of the vinylal fibre in the Wet-laid non-woven fabric is located at above-mentioned scope, even event in use can not peeled off by the fibre sheet material that melt spraying non-woven fabrics and wet cloth formula nonwoven constitute yet, not only can obtain the high dust bag of arresting efficiency, also can capture particle diameter expeditiously is the following superfine particle of 1 μ m, and the utmost point is not easy to cause the plug-hole phenomenon.
Among the present invention, available rupture strength is difficult for producing the yardstick of peeling off as expression melt spraying non-woven fabrics and Wet-laid non-woven fabric.This rupture strength is measured with rice homotopy type method low pressure analyzer, and its value is above more satisfactory for 196kPa, for then better more than the 294kPa.In addition, under moisture state, be preferably more than the 69kPa, it is then better to have the above rupture strength of 88kPa.That is, no matter electric cleaner of the present invention is at drying regime or moisture state with dust bag, in use all has good fracture-resistant.
Also can cooperate other fibers in this Wet-laid non-woven fabric, other fibers of cooperation can be synthetic fibers or paper pulp etc.But in order to keep the homogenieity of texture evenness, the most handy paper pulp.In order to give sheet material bulkiness and gas permeability, preferably and synthetic fibers and usefulness, both suitably mix, cooperate then better.But, if the consumption of paper pulp increases, often cause that then air permeance resistance increases, in addition, when the composite rate of synthetic fibers increased, the caking property decline with the polyethenol series viscose fibre often was difficult to obtain necessary strength.Kraft pulp (NUKP) is not shone in qualification that the paper pulp that the present invention uses has nothing special, available coniferous tree, coniferous tree is shone kraft pulp (NBKP), broad leaf tree solarization kraft pulp (LBKP), coniferous tree solarization sulfite pulp wood pulps such as (NBSP).
The order of this Wet-laid non-woven fabric is paid and is preferably 30-65g/m
2, be 40-60g/m
2Then better.Order is paid less than 30g/m
2The time, can not get strengthening fully effect and interlaminar bonding effect, otherwise, if surpass 65g/m
2Then too thick, the operation of final goods is often inconvenient.In addition, under the situation of stacked this Wet-laid non-woven fabric on the two sides of above-mentioned melt spraying non-woven fabrics, the total order of employed Wet-laid non-woven fabric paid adjust to above-mentioned scope and get final product.This Wet-laid non-woven fabric can be with general paper process manufacturing.
Among the present invention, outer bag uses the fibre sheet material that melt spraying non-woven fabrics and Wet-laid non-woven fabric are laminated, but from guaranteeing the viewpoint of high arresting efficiency, the order of this fibre sheet material is paid and is 35-80g/m
2, be preferably 40-70g/m
2The laminating method of this fibre sheet material is not particularly limited, the drying of for example in the papermaking operation of Wet-laid non-woven fabric, using stacked melt spraying non-woven fabrics on the felt face of felt drying machine, carry out drying and method such as stacked simultaneously, can be described as the adhesion strength height, the desirable method of less expensive on technology.Which kind of method no matter is not reducing arresting efficiency and is increasing that to carry out firm bonding under the situation of the pressure loss be very important because of stacked.Among the present invention, use occasion, preferably Wet-laid non-woven fabric is configured to the outermost layer of dust bag at the fibre sheet material of the stacked Wet-laid non-woven fabric of one side that melts and sprays.
Below, the inner bag that constitutes dust-collecting bags for electric dust cleaners is explained.
As inner bag of the present invention, the filter paper of available common usefulness, dry type nonwoven, Wet-laid non-woven fabric etc., but from arresting efficiency with two kinds of performances of the pressure loss are all good and use the viewpoint also be not easy broken bag, the most handy nonwoven when moistening.Among the present invention, the main effect of inner bag is that the capture particle diameter is the above big dust than the coarse grain footpath of 30 μ m, and particle diameter is that the following superfine dust of 1 μ m passes through from inner bag, by outer bag capture.
Particularly in the present invention, the most handy order of inner bag is paid and is 10-50g/m
2, the moistening intensity of vertical and horizontal is that the above and moistening elongation of 15N/5cm is, air permeability is 50cc/cm more than 20%
2The nonwoven that sec is above.Use this nonwoven, inner bag can more effectively capture the big dust of particle diameter.Make the thin dust of particle diameter optionally by outer bag,, can obtain being difficult for stopping up the dust bag of eyelet so available outer bag only captures the tiny dust of particle diameter.
Form inner bag and can use the fiber that constitutes by thermoplasticity polymer such as nylon, polyester, polypropylene with the fiber of nonwoven, but according to reasons such as heat seal are good, especially good with polypropylene.The nonwoven that the present invention uses, spunbonded type (non-woven) fabric is particularly suitable for, but the dry type nonwoven of the heat-sticking type made from carding machine, because of the air permeability die is suitable for using.In addition, spun bond nonwoven fabric and the stacked material more than two layers of melt spraying non-woven fabrics also can be used.
The order of the nonwoven that inner bag is used is paid and is preferably 5-50g/m
2, be 10-30g/m
2Especially good.Order is paid less than 5g/m
2The time, arresting efficiency reduces, and dust will soon stop up the eyelet of outer bag, influences the life-span of dust bag, moistening insufficient strength height, the moisture of seizure tends to cause broken bag.In addition, pay above 50g/m as if order
2, then the pressure loss is excessive, and the suction of dust catcher tends to reduce.
This nonwoven is vertically and moistening intensity transversely is more than the 15N/5cm, the breaking elongation degree is under the situation 20% or more, can prevent that this point is more satisfactory because of dust catcher dust suction simultaneously, the moistening broken bag that causes of inner bag that causes when absorbing water.The so-called MD direction that vertically means nonwoven among the present invention, transverse tie is represented the CD direction.
Inner bag is preferably 50cc/cm with the air permeability of nonwoven
2More than the sec, be 200cc/cm
2Then better more than the sec.Less than 50cc/cm
2During sec, inner bag is very fast just to cause obstruction, and the pressure loss when dust catcher uses often increases.
Dust-collecting bags for electric dust cleaners of the present invention for example uses above-mentioned inner bag and outer bag as the bag main body, can make by establish installing plate on this bag main body.Be provided with on bag main body and installing plate and import the introducing port that dust is used, the introducing port of bag main body and installing plate bonds very identically.The material that constitutes installing plate has nothing special qualification, available ground paper or synthetic resin.The shape of dust-collecting bags for electric dust cleaners of the present invention is not particularly limited, and suitably sets according to the electric dust collector that uses to get final product.
The dust-collecting bags for electric dust cleaners that obtains can be installed on the electric cleaner and use.
