本考案は、熱可塑性重合体のチップに液状添加剤を添加
混合しながら溶融紡糸するエクストルーダー型混合紡糸
装置に関するものである。[Detailed Description of the Invention] The present invention relates to an extruder type mixing and spinning device that performs melt spinning while adding and mixing liquid additives to chips of a thermoplastic polymer.
溶融紡糸法によシ合成繊維を製造する場合、改質繊維を
得る目的等でチップに各種の添加剤を添加混合して紡糸
することが広く行なわれている。When producing synthetic fibers by the melt spinning method, it is widely practiced to add and mix various additives to chips and then spin them for the purpose of obtaining modified fibers.
かかる場合、従来一般にチップと添加剤とをロータリー
型、ダブルコーン型等のプレンダーで攪拌混合した後エ
クストルーダーに供給する方法が採用されている力ζこ
のような方法では添加剤が液状であって粘度が低い場合
あるいは添加率が高い場合には均一な添加が不可能であ
るばかりか、甚しいときには添加剤がチップと分離しブ
レンダー内に残留する事態が生じる。In such cases, the conventional method has been to stir and mix chips and additives in a rotary type, double cone type blender, etc. and then supply them to an extruder. When the viscosity is low or when the addition rate is high, uniform addition is not only impossible, but in extreme cases, the additive may separate from the chips and remain in the blender.
また、添加剤の粘度釦よび添加率の適性な領域において
は、添加後が生じることはないがブレンダー内壁および
プレンダーからエクストルーダーにいたる間のチップ移
送管内壁等に添加剤が付着するめで正確法添加率を知り
難いし、添加剤の残留付着は製造銘柄の変更時の１とな
る。In addition, if the additive viscosity button and addition rate are in the appropriate range, there will be no after-addition, but the additive will adhere to the inner wall of the blender and the inner wall of the chip transfer pipe between the blender and the extruder, so it is difficult to accurately process the additive. It is difficult to know the addition rate, and residual adhesion of additives becomes a problem when changing the manufacturing brand.
また、個々のチップ表面に１んべんなぐ均一に添加剤を
付着させるとエクストルーダーへの噴込不良を生じるこ
とが多々ある。Further, if the additive is uniformly applied to the surface of each chip, injection into the extruder often occurs.
さらに、ブレンダーの設置していない紡糸系列ではブレ
ンダーの新設が必要となり、多額の投資を伴う。Furthermore, in spinning lines that do not have a blender installed, it is necessary to install a new blender, which requires a large amount of investment.
本考案はかかる従来の欠点を除去した混合紡糸装置を提
供するもので、熱可塑性重合体のチップに液状添加剤を
添加混合しながら溶融紡糸するエクストルーダー型紡糸
装置にかいて、チップサイロからエクストルーダーにい
たるチップ供給管の中心部に、定量ポンプから送られる
液状添加剤の導入管を開口せしめ、かつ該定量ポンプの
駆動をエクストルーダーのスクリュー軸との連結ｊｌ動
トしたことを特徴とするものである。The present invention provides a mixing spinning device that eliminates such conventional drawbacks, and uses an extruder-type spinning device that melt-spuns thermoplastic polymer chips while adding and mixing liquid additives. An introduction pipe for the liquid additive sent from a metering pump is opened in the center of the chip supply pipe leading to the extruder, and the metering pump is driven by a connection with the screw shaft of the extruder. It is something.
第１図は本考案の装置の説明図で、１はエクストルーダ
ー、２はチップサイロ、３はチップ供給管、４は添加剤
タンク、５は定量ポンプ、６は添加剤導入管である。FIG. 1 is an explanatory diagram of the apparatus of the present invention, in which 1 is an extruder, 2 is a chip silo, 3 is a chip supply pipe, 4 is an additive tank, 5 is a metering pump, and 6 is an additive introduction pipe.
７はモーターであシ、エクストルーダーのスクリュー軸
と定量ポンプの駆動軸とは変速機８を介して連結されて
いる。7 is a motor, and the screw shaft of the extruder and the drive shaft of the metering pump are connected via a transmission 8.
チップ供給管にかける添加剤導入管の位置はエクストル
ーダーのスクリューから近いことが望１しく、ｉｏｏ礪
以内の位置に設置するのが最適である。It is desirable that the additive introduction pipe connected to the chip supply pipe be located close to the screw of the extruder, and it is optimal to install it within an IOO depth.
また、添加剤導入管の内径および外径は添加削の導入量
およびチップ供給管の内径によって変更するのが良く、
チップ供給管内に挿入される添加剤導入管の外径はチッ
プ供給管の内径の３分の１以下にするのが望ましい。In addition, it is good to change the inner and outer diameters of the additive introduction pipe depending on the amount of additive cutting introduced and the inner diameter of the chip supply pipe.
It is desirable that the outer diameter of the additive introduction pipe inserted into the chip supply pipe be one-third or less of the inner diameter of the chip supply pipe.
會た、添加剤導入管の内径は導入管内の添加剤の流速が
０．１ ｍ１５＋〜１０ｍ／分になるように設定するこ
とが望ましい。In addition, the inner diameter of the additive introduction pipe is desirably set so that the flow rate of the additive within the introduction pipe is 0.1 m15+ to 10 m/min.
添加剤の添加率が高い場合には添加剤導入管の吐出口を
複数個とすることで、均一な添加が可能となる。When the addition rate of the additive is high, by providing a plurality of discharge ports of the additive introduction pipe, uniform addition becomes possible.
なお、液状添加剤の粘度を適性に保つために、添加剤系
に温度調節手段を設けることが望ましい。In addition, in order to maintain the viscosity of the liquid additive at an appropriate level, it is desirable to provide a temperature control means in the additive system.
以上のような本考案によれば、導入した液状添加剤がす
べてポリマー中に均一に混入され、しかもエクストルー
ダーへの噴込不良も生じることなく紡糸することが可能
となる。According to the present invention as described above, all the introduced liquid additives are uniformly mixed into the polymer, and furthermore, it becomes possible to perform spinning without causing any defective injection into the extruder.
また、製造銘柄の変更も支障なく行なうことが可能であ
る。Furthermore, it is possible to change the manufacturing brand without any problem.
さらに、本考案によれば、モーター金エクストルーダー
１台当り１台節約できるとともに次のような利点がもた
らされる。Moreover, according to the present invention, one motor gold extruder can be saved and the following advantages are brought about.
すなわち、定量ポンプを別駆動にすると、１エクストル
ーダーから複数のスピンヘッドにポリマーを供給する方
式の紡糸機にち・いては、ノズルパック交換等で一部の
錘が体錘することがしばしば生じ、この場合当然エクス
トルーダーのポリマー吐出量が低下するので添加率が増
大する欠点があったが、本考案によう定量ポンプの駆動
をスクリュー軸との連結駆動方式にすることにより、こ
の問題が解決されることである。In other words, when the metering pump is driven separately, in spinning machines that supply polymer from one extruder to multiple spin heads, some of the spindles often become unbalanced due to nozzle pack replacement, etc. In this case, of course, there was a disadvantage that the extruder's polymer discharge rate decreased and the addition rate increased, but this problem was solved by using the method of driving the metering pump connected to the screw shaft as in the present invention. It is to be done.
