Description
本発明は紡績方法及び紡績糸に関する。近年の紡績工程は、生産コストの低減や生産性の向上を図るため、高速リング精紡機を用いた紡績、高速ローター式オープンエンド精紡機を用いた紡績、渦流空気精紡機を用いた紡績等の高速紡績への転換が進んでいる。しかし、このように紡績速度が高速化すると、単位時間に紡績機械を通過する繊維量が速度に比例して多くなるため、スカムの堆積が増大して清掃周期が短くなり、操業性を低下させるようになっている。本発明は特に渦流空気精紡機を用いた紡績方法に関し、渦流空気精紡機を用いて繊維を紡績するときにスカムの発生を抑え、良好な高速紡績性の下に操業することができる紡績方法及びかかる紡績方法により得られる紡績糸に関する。 The present invention relates to a spinning method and a spun yarn. In recent years, spinning processes such as spinning using a high-speed ring spinning machine, spinning using a high-speed rotor-type open-end spinning machine, spinning using a vortex air spinning machine, etc. have been performed in order to reduce production costs and improve productivity. Conversion to high-speed spinning is progressing. However, when the spinning speed is increased in this way, the amount of fibers passing through the spinning machine per unit time increases in proportion to the speed, so that the accumulation of scum increases, the cleaning cycle is shortened, and the operability is lowered. It is like that. The present invention particularly relates to a spinning method using a vortex air spinning machine, and a spinning method capable of suppressing the occurrence of scum when spinning a fiber using a vortex air spinning machine and operating under good high-speed spinning. The present invention relates to a spun yarn obtained by such a spinning method.
従来、繊維の紡績では、良好な紡績性を得るため、アルキルリン酸エステルカリウム塩を用いた各種の繊維用処理剤が使用されている。かかる繊維用処理剤には、1)アルキルリン酸エステルカリウム塩と、アルキルアミノエーテル型ノニオンのリン酸中和物との2成分系(例えば特許文献1参照)、2)アルキルリン酸エステルカリウム塩と、アルキルアミノエーテル型ノニオンのリン酸中和物と、高分子量のポリオキシエチレン化合物との3成分系(例えば特許文献2参照)、3)アルキルリン酸エステルカリウム塩と、高分子量のポリオキシエチレン化合物との2成分系(例えば特許文献3参照)、4)アルキルリン酸エステルカリウム塩と、パラフィンワックス乳化物と、カチオン型界面活性剤との3成分系(例えば特許文献4参照)等が知られている。ところが、これら従来の繊維用処理剤を使用すると、高速リング精紡機を用いた紡績の場合にはアンチノードリングに、また高速ローター式オープンエンド精紡機を用いた紡績の場合にはローター内に、更に渦流空気精紡機を用いた紡績の場合にはスピンドルにスカムが堆積するという問題がある。なかでも渦流空気精紡機を用いた紡績での糸紡出速度は、高速リング精紡機や高速ローター式オープンエンド精紡機を用いた紡績での糸紡出速度に比べてはるかに速いため、スカムが堆積するという問題が大きい。このようにスカムが堆積すると、それだけ清掃周期が短くなって操業性を低下させるだけでなく、繊維が大きな損傷を受けて糸強力が低下したり、白粉や糸切れが著しく増加する。渦流空気精紡機を用いた紡績において、スカムの堆積を防止するため、界面活性剤を供給することも提案されているが(例えば特許文献5)、かかる界面活性剤として従来から繊維用処理剤に用いられてきたアルキルリン酸エステルカリウム塩のようなものを用いると、スカムの堆積を充分に抑えることができない。 Conventionally, in fiber spinning, various fiber treatment agents using alkyl phosphate potassium salt have been used in order to obtain good spinnability. Such fiber treating agents include 1) a two-component system of an alkyl phosphate ester potassium salt and a phosphoric acid neutralized alkylamino ether type nonion (see, for example, Patent Document 1), and 2) an alkyl phosphate ester potassium salt. A three-component system of a neutralized phosphoric acid of an alkylaminoether type nonion and a high molecular weight polyoxyethylene compound (see, for example, Patent Document 2), 3) an alkyl phosphate potassium salt, and a high molecular weight polyoxy 2 component system with ethylene compound (for example, refer to Patent Document 3), 4) 3 component system of alkyl phosphate ester potassium salt, paraffin wax emulsion, and cationic surfactant (for example, refer to Patent Document 4) Are known. However, when these conventional fiber treatment agents are used, in the case of spinning using a high-speed ring spinning machine, in anti-node ring, and in the case of spinning using a high-speed rotor type open-end spinning machine, in the rotor, Furthermore, in the case of spinning using a vortex air spinning machine, there is a problem that scum accumulates on the spindle. In particular, the yarn spinning speed in spinning using a vortex air spinning machine is much faster than the spinning speed in spinning using a high-speed ring spinning machine or a high-speed rotor type open-end spinning machine. The problem of accumulation is great. When scum accumulates in this way, not only the cleaning cycle is shortened and the operability is lowered, but also the fiber is greatly damaged and the yarn strength is lowered, and white powder and yarn breakage are remarkably increased. In order to prevent the accumulation of scum in spinning using a vortex air spinning machine, it has been proposed to supply a surfactant (for example, Patent Document 5). If the alkyl phosphate potassium salt that has been used is used, scum accumulation cannot be sufficiently suppressed.
本発明が解決しようとする課題は、渦流空気精紡機を用いた紡績においてスカムの堆積を充分に抑え、良好な高速紡績性の下に操業することができる紡績方法及びかかる紡績方法により得られる紡績糸を提供する処にある。 The problem to be solved by the present invention is a spinning method capable of sufficiently suppressing scum accumulation in spinning using a vortex air spinning machine and operating under good high-speed spinning performance, and spinning obtained by such a spinning method. We are in the process of providing yarn.

Test category 3 (vortex air spinning and evaluation)
The product name Vortex (registered trademark) manufactured by Murata Kikai Co., Ltd. was used as the vortex air spinning machine, and the fiber treatment agent prepared in Test Category 1 was mixed into the compressed air of the vortex air spinning machine and sprayed onto the fibers. The sprayability and scum depositability at this time were evaluated by the following methods, and the results are summarized in Table 3.
用いた渦流空気精紡機は複数の精紡ユニットを備え、各精紡ユニットは、ドラフト装置と、渦流空気精紡装置と、巻取装置とを備えている。ドラフト装置は、繊維束をドラフトし、渦流空気精紡装置へ供給する。また渦流空気精紡装置は、渦流空気流を内部に発生させて、前記繊維束を紡績し、紡績糸を生成させる。そして巻取装置は、渦流空気精紡装置から紡出され、適宜の糸送り手段で送られてきた紡績糸をパッケージに巻き取る。 The used vortex air spinning machine includes a plurality of spinning units, and each spinning unit includes a draft device, a vortex air spinning device, and a winding device. The draft device drafts the fiber bundle and supplies it to the vortex air spinning device. Further, the vortex air spinning device generates a vortex air flow inside, spins the fiber bundle, and generates a spun yarn. The winding device winds the spun yarn that has been spun from the vortex air spinning device and sent by an appropriate yarn feeding means onto the package.
前記の渦流空気精紡装置は、紡績室、繊維案内部、渦流発生ノズルが形成されたノズルホルダー部分及びスピンドル(中空ガイド軸体)を備えている。繊維案内部は、ドラフト装置によって形成された繊維束を紡績室内に案内する。紡績室は、繊維案内部、ホルダー部分及びスピンドルにより囲まれて形成された空間である。渦流発生ノズルは、紡績室内に圧縮空気を噴射して渦流を発生されることで、紡績室内に案内された繊維束の繊維端をスピンドル先端の領域で反転させつつ旋回させる。スピンドルは、紡績された糸を紡績室内から渦流精紡装置の外部へ案内する。スピンドルは、その先端部とは反対側の基端部がスピンドルホルダー部分により保持されている。 The vortex air spinning device includes a spinning chamber, a fiber guide portion, a nozzle holder portion in which a vortex generating nozzle is formed, and a spindle (hollow guide shaft). The fiber guide part guides the fiber bundle formed by the draft device into the spinning chamber. The spinning chamber is a space formed by being surrounded by the fiber guide portion, the holder portion, and the spindle. The swirl flow generating nozzle jets compressed air into the spinning chamber to generate swirl, thereby rotating the fiber end of the fiber bundle guided into the spinning chamber while reversing it in the region of the spindle tip. The spindle guides the spun yarn from the spinning chamber to the outside of the vortex spinning device. The base end of the spindle opposite to the tip is held by the spindle holder portion.
また用いた渦流空気精紡機は繊維用処理剤をミスト化させて混入させる噴霧装置(村田機械株式会社製の商品名ポリマスター)を備えている。この噴霧装置は、渦流発生ノズルの上流側の位置において、紡績室内に案内される圧縮空気に繊維用処理剤をミスト状に混入する。噴霧装置は、各渦流空気精紡装置に繊維用処理剤を直接供給するように構成されていてもよいし、複数の渦流空気精紡装置に空気を供給する共通の供給管に繊維用処理剤を供給するように構成されていてもよい。これらの詳細は、例えば特開2008−95208号公報や特開2011−84854号公報に記載されている。 Further, the vortex air spinning machine used is equipped with a spraying device (trade name Polymaster manufactured by Murata Machinery Co., Ltd.) that mists and mixes the fiber processing agent. This spraying device mixes the fiber treatment agent in a mist form into the compressed air guided into the spinning chamber at a position upstream of the vortex generating nozzle. The spray device may be configured to directly supply the fiber treatment agent to each vortex air spinning device, or to a common supply pipe that supplies air to a plurality of vortex air spinning devices. May be configured to supply. Details of these are described in, for example, Japanese Unexamined Patent Application Publication Nos. 2008-95208 and 2011-84854.
