Description

【0001】
【産業上の利用分野】
本発明は単繊維集合体の連続加工方法とその装置に関し、さらに詳しくは主に液体アンモニア、苛性ソーダ等の薬液で単繊維集合体を仕上加工するための連続加工方法とその装置に関する。
ここで、単繊維集合体とは連続した紐状の繊維をゆるく集めて横断面でほぼ均一になった繊維の集合体をいい、特に緊張状態にできないものをいう。
【0002】
【従来の技術】
繊維の仕上加工は編織物に審美的効果や機能性等を付与する目的で行われる。かかる目的を達成するために対象素材や薬剤に応じて様々な加工方法や装置が従来から開発されてきた。
【0003】
例えば、木綿セルロースは液体アンモニアに接触させて繊維内の結晶構造を変えることにより、風合いを柔らかくし、寸法セット性と乾時防しわ性を向上させている。
またポリエステル繊維はアルカリ濃厚溶液で溶食させることにより、繊維本来の剛直感をなくし、さらに減量化に伴う糸細りで繊維組織そのものをルーズにして絹様の風合いを付与している。
【0004】
これらの仕上加工は時代の要請で加工量が増大するにつれ、つり方式、ジッカー方式、ウインス方式などのバッチ方式からパッドスチーム方式、パッドドライ方式などの連続方式が主流になっている。
【0005】
しかしながら、織物の状態で連続方式により仕上加工すると、外力が繊維に加わり、繊維の剛直感が残り、繊維本来の特長を十分に生かせないおそれがあった。また、緊張状態にできない単繊維集合体を仕上加工する場合、繊維を引張れないためバッチ方式による加工はできても連続方式による大量加工は困難であった。
【0006】
【発明が解決しようとする課題】
本発明はかかる従来技術の現状に鑑み創案されたものであり、その目的とするところは緊張状態にできない単繊維集合体を良好に連続的に仕上加工するための方法とその装置を提供することにある。
【0007】
【課題を解決するための手段】
本発明者は上記目的を達成するために鋭意研究した結果、本発明の完成に到達した。
即ち、本発明は入口及び出口にシール装置がそれぞれ付設された連続加工装置を用いて、単繊維集合体を上下対の無端ネットコンベアで挟持した状態で、前記単繊維集合体に薬液を浸漬により付与する工程、絞り工程及び乾燥工程を含む工程に連続的に通過させることを特徴とする単繊維集合体の連続加工方法である。
【0008】
本発明の方法の好ましい態様では、前記工程にさらに洗浄(スチーミング)工程を含むことができる。
【0009】
また、本発明は入口及び出口にシール装置がそれぞれ付設されており、単繊維集合体に薬液を浸漬により付与する手段、前記集合体を絞る手段、前記集合体を乾燥する手段、及び前記各手段を連続的に行うための前記集合体の走行手段を含む単繊維集合体の連続加工装置において、前記走行手段が前記集合体を上下対の無端ネットコンベアで挟持した状態で走行するための機構を有することを特徴とする単繊維集合体の連続加工装置である。
【0010】
本発明の装置の好ましい態様では前記手段にさらに洗浄(スチーミング)手段を含むことができる。なお、絞り手段としてはゴムローラ等による通常の絞り手段の他、真空、エアジェット等による液分除去手段も採用することができる。
【0011】
【作用】
以上のように構成された本発明の装置では、単繊維集合体が上下対の無端ネットコンベアで挟持された状態で各工程を連続的に通過するので、外力が繊維に加わることがなく、繊維本来の特長を十分に生かせて様々な仕上加工をすることができる。
【0012】
また、本発明の装置では、上下対の無端ネットコンベアで挟持された状態で各工程を通過するので、緊張状態にできない単繊維集合体を仕上加工する場合でも連続的に大量に処理することができる。
【0013】
【実施例】
次に本発明の方法及び装置の一例を下記の実施例により具体的に説明するが、本発明はこれらに限定されるものではない。
【0014】
図1は本発明の単繊維集合体の連続加工方法を実施するための装置を表わしたものである。
図1によれば、本発明の装置は薬液付与のための浸漬室1、乾燥室2、スチーミング室3、前記各室に連続的に繊維を通過させるための上下対の無端ネットコンベア4,5から構成されている。
【0015】
単繊維集合体はまず搬入コンベア16で右方向に移動し下部ネットコンベア4上に落下して本発明の装置に導入される。このときに搬入コンベア16の速度と下部ネットコンベア4の相対速度は適宜可変制御できるようになっている。下部ネットコンベア4上に載置された単繊維集合体は下部ネットコンベア4と上部ネットコンベア5によって挟持され、その状態を保持した状態で装置内の各工程を通過する。装置内では単繊維集合体は薬液付与のための浸漬室1、乾燥室2、スチーミング室3を順次移動して各工程に供するようになっている。このように単繊維集合体を運搬する上下ネットコンベア4,5としては、耐熱、耐薬品性の合成繊維(例えばアラミド繊維)またはステンレス製ネットが使用でき、メッシュは約10〜20が適当である。
【0016】
浸漬室1では、単繊維集合体は上下ネットコンベア4,5で挟持した状態で薬液の満たされた浸漬槽6に浸漬して薬液を付与するようになっており、薬液の付与後駆動ゴムローラ8aと加圧ゴムローラ8bの圧力で単繊維集合体を絞り、液分を除去するようになっている。絞り手段は通常のゴムローラによる絞り手段以外に真空、エアジェット等による液分除去手段も採用することができる。なお、薬液はアンモニア、苛性ソーダ等のアルカリ処理液が用いられる。
【0017】
次に絞られて液分をある程度除去した単繊維集合体は乾燥室2に導入される。乾燥室2では単繊維集合体は熱風または遠赤外線等の加熱ヒータ9上を移動し、その移動に伴い加熱乾燥されるようになっている。また均一な乾燥手段を用いるならば、染料付与による染色も可能である。乾燥室2で蒸発しなかった薬液の残留物は次のスチーミング室3において除去される。スチーミング室3では図1のように上下ネットコンベア4,5の上下に交互に設けたスチームノズル10が設けられており、そこを通過する単繊維集合体にスチームを噴射させて付着した残留物を除去するようになっている。
【0018】
上記の各工程を終えた単繊維集合体はスチーミング室3から出口シール装置12を経て室外に出た後、上下ネットコンベア4,5による挟持状態が解除される。そして単繊維集合体は搬出コンベア17上に落下し、次工程へ送られる。
【0019】
浸漬室1の入口及びスチーミング室3の出口には室内ガス及びスチームが外部へ漏洩しないように入口シール装置11、出口シール装置12がそれぞれ付設されており、各シール装置は入口シール排気装置13、出口シール排気装置14によりガス等を室外に排気するようになっている。また、浸漬室1、乾燥室2及びスチーミング室3にはそれぞれ独自の排気装置15が付設され、シール装置の排気量とバランスをとりながらガス等を適宜排気するようになっている。
【0020】
本発明の方法及び装置は木綿、羊毛等の天然繊維の他、ポリエステル、アクリル、ナイロン等の合成繊維にも広く適用でき、特に緊張状態にできない織物の前段階の繊維集合体の仕上加工に有効である。また繊維集合体に限らず、例えばニット等を布状でフリーテンションで仕上加工することも可能である。
【0021】
【発明の効果】
上記のように本発明の方法及び装置は繊維を上下対の無端ネットコンベアで挟持した状態で連続的に仕上加工するので、外力が繊維に加わることなく繊維本来の特長を十分に生かせるとともに、緊張状態にできない繊維を仕上加工する場合も大量に処理することができる。

[Prior art]
The finishing treatment of the fiber is performed for the purpose of imparting an aesthetic effect, functionality, and the like to the knitted fabric. In order to achieve such an object, various processing methods and apparatuses have been conventionally developed according to the target material and the chemical.
[0003]
For example, cotton cellulose is brought into contact with liquid ammonia to change the crystal structure in the fiber, thereby softening the hand, improving the dimension setting property and the dry wrinkle resistance.
Polyester fibers are eroded with a concentrated alkali solution, thereby eliminating the inherent rigidity of the fibers, and further reducing the weight of the fibers to loosen the fiber structure itself to give a silky texture.
[0004]
With the demand for the times, as the processing amount increases, these finishing processes have become the mainstream from a batch system such as a hanging system, a zipper system and a win system to a continuous system such as a pad steam system and a pad dry system.
[0005]
However, when finishing is performed by a continuous method in the state of a woven fabric, an external force is applied to the fibers, the rigidity of the fibers remains, and the inherent characteristics of the fibers may not be fully utilized. Further, when a single fiber aggregate that cannot be tensioned is subjected to finish processing, the fibers cannot be pulled, so that batch processing can be performed but mass processing by a continuous method has been difficult.

[0008]
In a preferred embodiment of the method of the present invention may include the wash to further the process (steaming) process.
[0009]
Further, in the present invention , a sealing device is attached to each of the inlet and the outlet, a means for applying a chemical solution to the single fiber aggregate by dipping, a means for squeezing the aggregate, a means for drying the aggregate, and each of the means in the continuous machining device of the single fiber aggregate comprising traveling means of the assembly for performing continuous, mechanisms for traveling in a state where the traveling means is sandwiching the assembly with paired upper and lower endless net conveyor It is a continuous processing apparatus of a single fiber aggregate characterized by having.

After the individual fiber aggregates that have been subjected to the above-described steps exit the room from the steaming chamber 3 via the outlet sealing device 12, the holding state of the upper and lower net conveyors 4, 5 is released. Then, the single fiber aggregate falls onto the carry-out conveyor 17 and is sent to the next step.
[0019]
An inlet seal device 11 and an outlet seal device 12 are provided at an inlet of the immersion chamber 1 and an outlet of the steaming chamber 3 so as to prevent room gas and steam from leaking to the outside. The outlet seal exhaust device 14 exhausts gas and the like to the outside of the room. Further, each of the immersion chamber 1, the drying chamber 2 and the steaming chamber 3 is provided with its own exhaust device 15 so as to appropriately exhaust gas or the like while keeping the exhaust amount of the sealing device in balance.
