Description

技術分野
本発明は化学繊維の不織布を連続的に製造する方法及び装置に関する。
背景技術
化学繊維の不織布は、低融点の繊維と高融点の繊維との混合集合体（ウェブ）を該低融点の繊維の融点以上に加熱して繊維同士を結合することにより製造されることがある。低融点繊維と高融点繊維との混合ウェブの代りに、高融点繊維の芯材の表面（周囲）に低融点樹脂層を形成した芯鞘構造の化学繊維の集合体をウェブとして用いることもある。
従来の方法にあっては、このウェブを加熱して不織布とする場合、所定寸法のウェブをバッチ式に加熱処理しているため、作業が煩雑であった。また、製品を得るまでに要する時間が長い。さらに、加熱室に供給する際にウェブにしわが入り、製品に粗密が生じ易い。
発明の開示
本発明は、所望の密度の不織布を連続的に製造する方法及び装置を提供することを目的とする。
本発明によると、不織布は、低融点化学繊維を含むウェブ又は低融点表面層を有する化学繊維を含むウェブを加熱することにより製造され、ここにおいて、該ウェブは搬送されて連続的に加熱室内を通過され、これによって不織布が連続的に製造される。
本発明の不織布の製造装置は、低融点化学繊維を含むウェブ又は低融点表面層を有する化学繊維を含むウェブを搬送するメッシュコンベアと、該メッシュコンベアの搬送途中に設けられた加熱室と、該加熱室から出てきたウェブをプレスして所定厚みに調整するロールとを有する。
かかる製造方法及び装置によると、ウェブにしわを生じさせることなく連続的に不織布が製造される。
加熱室から出てきたウェブをロールで挟んでプレスして所定厚みとすることにより、所望の密度の不織布が連続的に製造される。
ウェブをメッシュコンベアによって搬送することにより、ウェブに熱風が均一に当たり、これによって加熱時間が短縮化されると共に、不織布製品に搬送痕がつくことが防止される。
加熱室内において、熱風を下から上に通すことにより、ウェブの厚みが維持され、所望の密度の不織布が製造される。
搬送されるウェブを上方から第２のメッシュコンベアで挟むことにより、所望の厚さ及び密度の不織布が容易に製造される。ウェブが上下双方からメッシュコンベアで挟まれることにより、不織布の両面ともに風合いの良好なものとなる。
発明の好ましい形態
以下、図面を参照して実施の形態について説明する。図１は実施の形態に係る不織布の製造方法及び装置の一例を示す概略的な縦断面図である。
ウェブは、低融点化学繊維と高融点化学繊維との混合ウェブ、又は低融点層を外層に有した芯鞘型の化学繊維よりなる。ウェブは、下側の第１のメッシュコンベア１と上側の第２のメッシュコンベア２とに挟まれて搬送され、加熱室３内を通過する。符号４は、第２のメッシュコンベア２を上下位置調整するためのスクリュジャッキ等の高さ調整機構を示す。
加熱室３の下部にはＬＰＧ燃焼器を有した熱風供給装置（図示略）が接続されており、メッシュコンベア１の下側に所定温度の熱風を供給するようにしている。加熱室１の上部には、ダクト５を介して誘引式の排気ファン（インダクションファン）６が接続されている。
加熱室３内にて加熱され繊維同士が結合して生じた不織布は、加熱室３から出たところでプレスロール８によって上下から挟圧され、所定厚みとされる。その後、不織布は、メッシュコンベア１１，１２に上下から挟まれて冷却装置１０内に導入され、例えば常温の空気が不織布に通されて冷却される。符号１３はこのメッシュコンベア１２の高さ調節用のスクリュジャッキを示す。
不織布は、次いで受台１６上に送り出され、カッター１５によって所定寸法に切断される。
この不織布の製造装置によれば、ウェブを連続的に加熱処理して不織布を連続的に製造することができる。
ウェブは、加熱室３内において上下からメッシュコンベア２，１によって挟まれて搬送されるので、粗密のバラツキがなく、しわの発生も防止される。このメッシュコンベア２，１間の間隔を入口側から出口側に向って徐々に小さくなるように調整することにより熱履歴を均一化させることができる。
このメッシュコンベア１，２として目の細かいものを用いることにより、ウェブに対し熱風を均一に通過させることができ、加熱処理時間を短縮できる。
このメッシュコンベア１，２はパンチング鉄板に比べて著しく均一に熱風をウェブに通すことができる。また、目が細かいので、不織布に痕がつくこともなく、上下両面の風合いが良好なものとなる。
メッシュコンベア１，２の間隔は、入口側が２０〜５００ｍｍ、出口側が５〜１００ｍｍの範囲で個別に自在に調整可能となっているものが好ましい。
また、入口側及び出口側におけるメッシュコンベア１との間隔が調整された第２のメッシュコンベア２を、上下方向に全体として平行に（即ち、同じ傾斜角度を保ったまま）移動させる機構を有することが望ましい。
熱源としてはヒータを用いてもよいが、低風速の運転において、ヒーターが焼きついてしまう恐れがあるため、ＬＰＧバーナによる熱源供給が好ましい。排気ファン６によりサクション引きすることにより、熱風の供給、流通が安定する。
この熱風は、好ましくは図１のように下から上へ通され、これによって、ウェブの厚みが維持され、そして、製造された不織布は所望の密度を有し得る。これに反し、熱風が上から下へ通された場合には、ウェブが風力及び自重で熱融着前に厚みが小さくなり、所望の密度の不織布とならないおそれがある。
プレスロール８は、冷却ロール、ヒータ付きロールのいずれでもよいが、冷却ロールの方が好ましい。加熱室３とプレスロール８との間には囲いを設け、不織布からの放熱を防ぐのが好ましい。不織布からの放熱により不織布の温度が低下すると、プレスの効果が乏しくなり、不織布の厚み調整が難しくなる。
プレスロール８で厚み調整された不織布を最終厚みに収縮させるために、好ましくは、冷却装置１０の上側メッシュコンベア１２と下側メッシュコンベア１１との間隔が入口側と出口側とで個別に調整可能となっている。冷却装置１０は、入口側及び出口側における下側メッシュコンベア１１との間隔が調整された上側メッシュコンベア１２を、上下方向に全体的に平行移動させる機構を有してもよい。
冷却装置１０は、冷却用空気の温度を制御する機構を有することが好ましい。冷却用空気の吹き付け方向は上下いずれからでもよいが、上から吹き付ける場合、風圧によりウェブの厚さを減少させる可能性があるので、下から吹き付ける方が好ましい。
本発明の方法及び装置は、密度０．０１〜０．２ｇ／ｃｍ３の不織布を製造するのに好適である。
ウェブを構成する高融点化学繊維と低融点化学繊維との組み合わせ、低融点層を外層に有した芯鞘型の化学繊維の芯と鞘との組み合わせとしては、ＰＰ（ポリプロピレン）／ＰＥ（ポリエチレン），ＰＥＴ（ポリエチレンテレフタレート）／ＰＰ，ＰＥＴ／ＰＥ，ＰＰＳ（ポリフェニレンサルファイド）／ＰＥＴ，ＰＰＳ／ＰＰ，ＰＰＳ／ＰＥなどが例示されるが、これに限定されるものではない。
メッシュコンベア１，２の材質は、ＰＰＳ，ＰＥＴなどの合成樹脂の他、ＳＵＳでもよいが、軽量で耐熱性の良いＰＰＳが好ましい。
加熱室３内においてウェブを通過する熱風の風速は０．０１〜５ｍ／ｓｅｃが好ましい。５ｍ／ｓｅｃ超では、ウェブにしわが生じるおそれがあり、また不織布の厚み制御も難しい。
加熱室３は上流側の予熱室と、下流側の熱融着室との２室方式とされてもよい。
加熱室３内に邪魔板を配置し、熱風を均一に流通させるようにしてもよい。邪魔板を設けることにより、高風速運転が可能になる。また、熱容量が増加し、室内温度を高温に維持できる。
産業上の利用可能性
以上の通り、本発明によると、所望の厚さ及び密度を有し、風合いの良好な不織布を連続的に製造することが可能となる。
【図面の簡単な説明】
図１は、実施の形態に係る不織布の製造装置の概略的な断面図である。TECHNICAL FIELD The present invention relates to a method and an apparatus for continuously producing a nonwoven fabric of chemical fibers.
BACKGROUND ART [0002] A nonwoven fabric of a chemical fiber is manufactured by heating a mixed aggregate (web) of low-melting fiber and high-melting fiber to a temperature equal to or higher than the melting point of the low-melting fiber and bonding the fibers. is there. Instead of the mixed web of the low-melting fiber and the high-melting fiber, an aggregate of chemical fibers having a core-sheath structure in which a low-melting resin layer is formed on the surface (around) of a core material of the high-melting fiber may be used as the web. .
In the conventional method, when the web is heated to form a non-woven fabric, the web is heat-treated in a batch manner with a predetermined size, so that the operation is complicated. Also, the time required to obtain the product is long. Further, when the web is supplied to the heating chamber, the web is wrinkled, and the product is likely to be uneven.
DISCLOSURE OF THE INVENTION An object of the present invention is to provide a method and an apparatus for continuously producing a nonwoven fabric having a desired density.
According to the present invention, the nonwoven fabric is produced by heating a web containing low-melting chemical fibers or a web containing chemical fibers having a low-melting surface layer, wherein the web is conveyed and continuously in a heating chamber. Through which the nonwoven is continuously produced.
The nonwoven fabric manufacturing apparatus of the present invention is a mesh conveyor for transporting a web containing low-melting chemical fibers or a web containing chemical fibers having a low-melting surface layer, a heating chamber provided on the way of transporting the mesh conveyor, And a roll for pressing the web coming out of the heating chamber to adjust the thickness to a predetermined value.
According to such a manufacturing method and apparatus, a nonwoven fabric is manufactured continuously without causing wrinkles in the web.
By pressing the web coming out of the heating chamber between rolls and pressing the web to a predetermined thickness, a nonwoven fabric having a desired density is continuously produced.
By transporting the web by the mesh conveyor, the hot air uniformly hits the web, thereby shortening the heating time and preventing the nonwoven product from having transport marks.
By passing hot air from below in the heating chamber, the thickness of the web is maintained, and a nonwoven fabric having a desired density is produced.
By sandwiching the conveyed web from above with the second mesh conveyor, a nonwoven fabric having a desired thickness and density can be easily manufactured. Since the web is sandwiched between the mesh conveyors from both the upper and lower sides, both sides of the nonwoven fabric have a good texture.
Preferred Embodiments of the Invention Embodiments will be described below with reference to the drawings. FIG. 1 is a schematic longitudinal sectional view illustrating an example of a method and an apparatus for manufacturing a nonwoven fabric according to an embodiment.
The web is composed of a mixed web of low-melting chemical fibers and high-melting chemical fibers, or a core-sheath type chemical fiber having a low-melting layer in the outer layer. The web is conveyed by being sandwiched between the lower first mesh conveyor 1 and the upper second mesh conveyor 2, and passes through the heating chamber 3. Reference numeral 4 denotes a height adjusting mechanism such as a screw jack for adjusting the vertical position of the second mesh conveyor 2.
A hot air supply device (not shown) having an LPG combustor is connected to a lower portion of the heating chamber 3 so as to supply hot air at a predetermined temperature to a lower side of the mesh conveyor 1. An induction type exhaust fan (induction fan) 6 is connected to an upper portion of the heating chamber 1 via a duct 5.
The nonwoven fabric produced by heating the heating chamber 3 and combining the fibers is pressed from above and below by the press rolls 8 when it comes out of the heating chamber 3 to have a predetermined thickness. Thereafter, the nonwoven fabric is introduced into the cooling device 10 by being sandwiched between the mesh conveyors 11 and 12 from above and below, and for example, air at normal temperature is passed through the nonwoven fabric and cooled. Reference numeral 13 denotes a screw jack for adjusting the height of the mesh conveyor 12.
The nonwoven fabric is then sent out onto a cradle 16 and cut by a cutter 15 to a predetermined size.
According to this nonwoven fabric manufacturing apparatus, the web can be continuously heated and the nonwoven fabric can be continuously manufactured.
Since the web is conveyed while being sandwiched between the mesh conveyors 2 and 1 from above and below in the heating chamber 3, there is no unevenness in the density and the occurrence of wrinkles is prevented. The heat history can be made uniform by adjusting the distance between the mesh conveyors 2 and 1 so as to gradually decrease from the entrance side to the exit side.
By using fine mesh conveyors 1 and 2, hot air can be uniformly passed through the web and the heat treatment time can be reduced.
The mesh conveyors 1 and 2 can pass hot air through the web significantly more uniformly than the punched iron plate. Further, since the eyes are fine, no marks are formed on the nonwoven fabric, and the texture on both the upper and lower surfaces is good.
It is preferable that the interval between the mesh conveyors 1 and 2 can be individually and freely adjusted within the range of 20 to 500 mm on the inlet side and 5 to 100 mm on the outlet side.
In addition, a mechanism is provided for moving the second mesh conveyor 2 in which the distance between the mesh conveyor 1 on the inlet side and the outlet side is adjusted in parallel in the vertical direction as a whole (that is, while maintaining the same inclination angle). Is desirable.
Although a heater may be used as the heat source, it is preferable to supply the heat source using an LPG burner because the heater may be burned in operation at a low wind speed. By suction suction by the exhaust fan 6, supply and distribution of hot air are stabilized.
The hot air is preferably passed from bottom to top as in FIG. 1, thereby maintaining the thickness of the web and the nonwoven fabric produced may have the desired density. On the other hand, when hot air is passed from top to bottom, the web becomes thin before heat fusion due to wind force and own weight, and there is a possibility that a nonwoven fabric having a desired density may not be obtained.
The press roll 8 may be either a cooling roll or a roll with a heater, but a cooling roll is more preferable. It is preferable to provide an enclosure between the heating chamber 3 and the press roll 8 to prevent heat radiation from the nonwoven fabric. When the temperature of the nonwoven fabric decreases due to heat radiation from the nonwoven fabric, the pressing effect becomes poor, and it becomes difficult to adjust the thickness of the nonwoven fabric.
In order to shrink the nonwoven fabric whose thickness has been adjusted by the press roll 8 to the final thickness, preferably, the interval between the upper mesh conveyor 12 and the lower mesh conveyor 11 of the cooling device 10 can be individually adjusted at the inlet side and the outlet side. It has become. The cooling device 10 may have a mechanism for vertically moving the upper mesh conveyor 12 in which the distances from the lower mesh conveyor 11 on the inlet side and the outlet side are adjusted as a whole.
The cooling device 10 preferably has a mechanism for controlling the temperature of the cooling air. The blowing direction of the cooling air may be either from the upper or lower direction. However, when blowing from above, it is preferable to blow from the bottom because there is a possibility that the thickness of the web may be reduced by wind pressure.
The method and the apparatus of the present invention are suitable for producing a nonwoven fabric having a density of 0.01 to 0.2 g / cm 3 .
As a combination of a high-melting chemical fiber and a low-melting chemical fiber constituting a web, and a combination of a core and a sheath of a core-sheath type chemical fiber having a low-melting layer in an outer layer, PP (polypropylene) / PE (polyethylene) , PET (polyethylene terephthalate) / PP, PET / PE, PPS (polyphenylene sulfide) / PET, PPS / PP, PPS / PE, etc., but are not limited thereto.
The material of the mesh conveyors 1 and 2 may be SUS in addition to synthetic resins such as PPS and PET, but PPS with light weight and good heat resistance is preferable.
The velocity of the hot air passing through the web in the heating chamber 3 is preferably 0.01 to 5 m / sec. If it exceeds 5 m / sec, the web may be wrinkled, and it is difficult to control the thickness of the nonwoven fabric.
The heating chamber 3 may be a two-chamber system including an upstream preheating chamber and a downstream heat fusion chamber.
A baffle may be arranged in the heating chamber 3 so that hot air can be distributed uniformly. By providing the baffle, high wind speed operation becomes possible. In addition, the heat capacity increases, and the room temperature can be maintained at a high temperature.
INDUSTRIAL APPLICABILITY As described above, according to the present invention, it is possible to continuously produce a nonwoven fabric having a desired thickness and density and a good texture.
