【発明の属する技術分野】
本発明は、換気扇またはレンジフードに取り付ける使い捨てのフィルター材に関する。
【0002】
【従来の技術】
調理場乃至は台所に用いられる換気扇又はレンジフードには、換気扇の羽根やレンジフードの内壁に、油等が付着し不衛生になるのを防止するため、或いは外部に油等が散逸するのを防止するために、フィルター材が取り付けられている。このフィルター材としては、一般的に、嵩高な不織布が用いられている。不織布は、天然繊維や合成繊維等を集積すると共に繊維間を何らかの手段で固定したものであり、一種の繊維集積体である。従って、調理場や台所で調理中に、炎が発生し、この炎が不織布に接触すると、火災が生じるという危険性があった。
【0003】
このため、従来より、不織布の構成繊維として、ハロゲン元素を含有する重合体で形成された難燃性繊維が用いられていた。具体的には、ポリ塩化ビニル系合成繊維,ポリ塩化ビニリデン系合成繊維,アクリル−塩化ビニリデン共重合体系合成繊維等の難燃性繊維が用いられていた。これらの難燃性繊維は、炎と接触しても燃え上がることが少なく、したがって、この難燃性繊維を用いた不織布は、換気扇用フィルター材やレンジフード用フィルター材として好ましいものであった。
【0004】
しかるに、近年、ポリ塩化ビニル系等のハロゲン元素を含有する重合体で形成された合成繊維を用いた不織布は、廃棄及び焼却時に、塩素ガス等のハロゲンガスが発生し、環境上好ましくないとの指摘がなされている。例えば、塩素ガスは、ダイオキシン等の環境ホルモン(内分泌攪乱物質)を生成する原因物質であるとの指摘がなされているのである。また、その他のハロゲンガスも環境上、好ましくないと言われている。
【0005】
このような状況下、塩素ガス等のハロゲンガスを発生しにくい難燃性繊維として、リン系難燃剤を練り込んだ繊維が開発されている。例えば、リン酸エステルやリン酸アンモニウム等のリン系難燃剤を練り込んだポリエステル繊維が開発されている(特許文献1〜3)。従って、この難燃性ポリエステル繊維を用いて不織布を作成し、これが耐熱性フィルター材として市販されている。しかし、この場合の不織布は難燃性ポリエステル繊維相互間を、低融点ポリエステル繊維で熱融着して固定されており、高熱または炎が接触すると、低融点ポリエステル繊維が溶融して落下し、調理場や台所を汚すことが多く、また、フィルター材に火の粉が飛んだり、高熱または炎が接触してフィルター材に孔があきフィルター性能を損ない易く、使用者には受け入れにくいものであった。他に、耐熱性フィルターとしてガラス繊維等の無機繊維をバインダーで固着して積層したマット状フィルターが市販されている。しかし無機繊維は容易に溶融することはないが、バインダーとしての固着剤の熱による焼失あるいは気流等による衝撃により繊維が飛散あるいは落下する恐れがある。

【発明が解決しようとする課題】
炎や火の粉に接触しても容易に溶融して孔があくこともなく、高温の液状溶融物が落下したり、気流等の衝撃により繊維が飛散あるいは落下しない無機繊維の不織布から成る換気扇またはレンジフード用使い捨てフィルター材を提供することを目的とする。
【0008】
【課題を解決するための手段】
本発明者らは、上記課題に対して鋭意検討を行った結果、無機繊維から成る不織布が金属線または無機繊維のネットで被覆されていることを特徴とする換気扇またはレンジフードに取り付ける使い捨てのフィルター材を創製することに成功し、それがこれまでに開発されたものが有する上記した種々の問題点を一挙に解決することを知見した。さらに検討を重ねて本発明を完成させるに至った。

すなわち、本発明は、
(1)無機繊維から成る不織布が金属線または無機繊維のネットで被覆されていることを特徴とする換気扇またはレンジフードに取り付ける使い捨てのフィルター材、
(2)不織布が厚さ約1〜25mmで、通気度が約300cm3/cm2/s以上であることを特徴とする(1)記載のフィルター材、

に関する。

【発明の実施の形態】
以下、本発明の実施の形態を説明する。
【0011】

【0013】
本発明でいう不織布は、上記した無機繊維から、例えばトウ開繊法、メルトブロー法、短繊維乾式法または短繊維湿式法等によりウエッブを形成し、通常、例えばポリエステル系またはエポキシ系のバインダーで処理して、不織布を構成する無機繊維相互間の結合を強固にすることによって製造される。バインダーの含有量は通常約2〜40質量%、好ましくは約5〜15質量%である。また、不織布として市販品が使用されてよい。種々の無機繊維からなる不織布の中でもガラス繊維から成る不織布(以後、ガラス繊維マットと称する)が好ましい。ガラス繊維のガラスの種類は、例えばEガラス、Cガラス、Sガラス等が使用され得るが、Eガラスが好ましい。無機繊維の単糸径は、通常約3〜50μ、好ましくは約10〜30μである。不織布の厚さは、通常約1〜25mm, 好ましくは約3〜10mmである。不織布の通気度は、通常約300cm3/cm2/s以上, 好ましくは約300〜600cm3/cm2/sである。通気度の測定はJISR3420に基づいて測定される。
【0014】

【0017】
本発明でいう無機繊維ネットとしては、例えば無機繊維を平織、朱子織、綾織、横縞織、からみ織または斜こ織などに製織することにより得られる織物が使用されてよい。織物の中でからみ織または平織が好ましい。また、例えば平編み、ゴム編みもしくはパール編みなどの横編み、シングルデンビー編みもしくはシングルデンビー編みなどの縦編み、またはレース編み等に製編することにより得られる編物が使用されてもよい。編物の中で平編みが好ましい。無機繊維ネットの開口部は通常約0.5〜10mm角、好ましくは約1〜5mm角である。
【0018】
次いで、無機繊維から成る不織布を金属線または無機繊維のネットで被覆する。被覆方法としては、通常公知の方法にてなされてよい。例えば、具体的には換気扇またはレンジフード用に適当な寸法に断裁された不織布に金属線または無機繊維のネットで表裏被覆し、その外周部を、例えばステープルで固定したり、ガラス繊維製縫製糸等の不燃性縫製糸で縫製したり、あるいは無機繊維から成る織編物で強化されたアルミ箔等で接着被覆したり、さらにその上をステープルで固定したり、ガラス繊維製縫製糸等の不燃性縫製糸で縫製したりするのが好ましい。これは、熱によるバインダーの焼失、または衝撃等によって不織布を構成する無機繊維が飛散したり、落下したりするのを防止するためである。なお、本発明のフィルター材は、所望により、例えばリン酸グアニジンなどの難燃化剤を、例えば無機繊維からなる不織布に添加してもよいが、これを加えなくとも充分な着火防止効果を有する。

BACKGROUND OF THE INVENTION
The present invention relates to a disposable filter material attached to a ventilation fan or a range hood.
[0002]
[Prior art]
In order to prevent oil from adhering to the ventilation fan blades and the inner wall of the range hood, and to dissipate the oil etc. to the outside. Filter material is attached to prevent. In general, a bulky nonwoven fabric is used as the filter material. A non-woven fabric is a kind of fiber assembly in which natural fibers, synthetic fibers, and the like are accumulated and fibers are fixed by some means. Accordingly, there is a risk that a flame is generated during cooking in a kitchen or a kitchen, and if this flame contacts the nonwoven fabric, a fire may occur.
[0003]
For this reason, conventionally, the flame-retardant fiber formed with the polymer containing a halogen element was used as a constituent fiber of a nonwoven fabric. Specifically, flame retardant fibers such as polyvinyl chloride synthetic fibers, polyvinylidene chloride synthetic fibers, and acrylic-vinylidene chloride copolymer synthetic fibers have been used. These flame retardant fibers hardly burn even when they come into contact with flames. Therefore, the nonwoven fabric using the flame retardant fibers is preferable as a filter material for a ventilation fan or a filter material for a range hood.
[0004]
However, in recent years, non-woven fabrics using synthetic fibers formed of polymers containing halogen elements such as polyvinyl chloride are not environmentally friendly because halogen gases such as chlorine gas are generated during disposal and incineration. It has been pointed out. For example, it has been pointed out that chlorine gas is a causative substance that produces environmental hormones (endocrine disrupting substances) such as dioxins. In addition, other halogen gases are also said to be undesirable from the environment.
[0005]
Under such circumstances, a fiber in which a phosphorus-based flame retardant is kneaded has been developed as a flame retardant fiber that hardly generates halogen gas such as chlorine gas. For example, polyester fibers in which a phosphorus-based flame retardant such as phosphate ester or ammonium phosphate is kneaded have been developed (

The nonwoven fabric referred to in the present invention forms a web from the above-described inorganic fibers by, for example, a tow opening method, a melt blow method, a short fiber dry method or a short fiber wet method, and is usually treated with, for example, a polyester or epoxy binder. And it manufactures by strengthening the coupling | bonding between the inorganic fibers which comprise a nonwoven fabric. The content of the binder is usually about 2 to 40% by mass, preferably about 5 to 15% by mass. Moreover, a commercial item may be used as a nonwoven fabric. Among nonwoven fabrics made of various inorganic fibers, nonwoven fabrics made of glass fibers (hereinafter referred to as glass fiber mats) are preferable. For example, E glass, C glass, S glass or the like may be used as the glass fiber glass, but E glass is preferred. The single yarn diameter of the inorganic fiber is usually about 3 to 50 μ, preferably about 10 to 30 μ. The thickness of the nonwoven fabric is usually about 1 to 25 mm, preferably about 3 to 10 mm. The air permeability of the nonwoven fabric is usually about 300 cm 3 / cm 2 / s or more, preferably about 300 to 600 cm 3 / cm 2 / s. The air permeability is measured based on JIS R3420.
[0014]
Examples of the metal wire for the net in the present invention include an iron wire, a copper wire, a nickel wire, and a stainless steel wire. Any metal wire may be used as long as it can form a net. Of these, stainless steel wire is preferred. The diameter of the metal wire for a net is about 0.01-2 mm normally, Preferably it is about 0.1-1 mm.
[0015]
Any inorganic fiber may be used as long as it can form a net as an inorganic fiber for a net in the present invention. For example, glass fiber, carbon fiber, activated carbon fiber, etc. are mentioned. Of these, glass fiber is preferable. The single yarn diameter of the inorganic fiber for a net is usually about 3 to 50 μm, preferably about 10 to 30 μm.
[0016]
The metal wire net in the present invention may be produced by a generally known method. Moreover, you may use a commercial item as a metal wire net. The opening of the metal wire net is usually about 0.5 to 10 mm square, preferably about 1 to 5 mm square. Here, the opening means the size of the grid of the net. The same applies hereinafter.
[0017]
As the inorganic fiber net in the present invention, for example, a woven fabric obtained by weaving inorganic fibers into a plain weave, satin weave, twill weave, horizontal stripe weave, leno weave, or diagonal weave may be used. Among the woven fabrics, twine or plain weave is preferred. Further, for example, a knitted fabric obtained by knitting into flat knitting, flat knitting such as flat knitting, rubber knitting or pearl knitting, vertical knitting such as single denby knitting or single denby knitting, or lace knitting may be used. Of the knitted fabrics, flat knitting is preferred. The opening of the inorganic fiber net is usually about 0.5 to 10 mm square, preferably about 1 to 5 mm square.
[0018]
Next, the nonwoven fabric made of inorganic fibers is covered with a metal wire or a net of inorganic fibers. As a coating method, a generally known method may be used. For example, a non-woven fabric cut to an appropriate size for a ventilation fan or a range hood is coated with a metal wire or inorganic fiber net on the front and back, and the outer periphery is fixed with, for example, staples or a glass fiber sewing thread Sewing with non-combustible sewing thread, etc., or adhesive coating with aluminum foil reinforced with woven or knitted fabric made of inorganic fibers, and fixing it with staples, non-combustibility of glass fiber sewing thread, etc. It is preferable to sew with a sewing thread. This is to prevent the inorganic fibers constituting the nonwoven fabric from being scattered or dropped due to burnout of the binder due to heat or impact. The filter material of the present invention may have a sufficient ignition preventing effect without adding a flame retardant such as guanidine phosphate to a nonwoven fabric made of inorganic fibers, for example, if desired. .
