Description
【考案の詳細な説明】
本考案は加熱して溶融又は軟化させたプラスチック、ガ
ラス等を溶融炉の底部に設けられたノツズルから垂下さ
せて紡糸する際、ノツズルプレートの下部に装着して使
用するノツズルマスクに係わるものである。[Detailed description of the invention] This invention is used by attaching it to the lower part of the nozzle plate when heating and melting or softening plastic, glass, etc., is suspended from the nozzle provided at the bottom of the melting furnace for spinning. This is related to a nozzle mask.
従来、上記のような溶融紡糸の場合、ノツズルは逆円錐
形でその下部出口は数粒ではあるが円筒状をなしていて
、溶融物はこの円筒内面に沿って垂下して繊維となる。Conventionally, in the case of melt spinning as described above, the nozzle has an inverted conical shape, and the lower outlet has a cylindrical shape, although there are several grains, and the molten material hangs down along the inner surface of this cylinder to become fibers.
従って粘度の高い溶融物、例えばガラスはその接触する
ノツズル出口の内面との摩擦による抵抗が可なり大きく
、この抵抗によって溶融物の垂下速度が減少し、その紡
糸量が制限され、又生成するフィラメントの径も小とな
る欠点があった。Therefore, a highly viscous melt, such as glass, has a considerable resistance due to friction with the inner surface of the nozzle outlet that comes in contact with it, and this resistance reduces the drooping speed of the melt, limits the amount of spinning, and reduces the amount of filament produced. It also had the disadvantage of having a small diameter.
本考案は上記の欠点を克服するもので、これを実施例の
図によって説明すると、溶融炉の炉底のノツズルプレー

７′を設けた溶融紡糸ノツズルマスクである。The present invention overcomes the above-mentioned drawbacks, and is explained by the drawings of an embodiment.The present invention can be airtightly installed under the nozzle plate 1 at the bottom of the melting furnace with its side plates 2, 2'.
The main body is a box-shaped body 4 consisting of a bottom plate 3 and side plates 2.
The bottom plate 3 has a cylindrical body 6 which surrounds the outlet of each nozzle 5 in the vicinity of the outlet of each nozzle 5 below the position corresponding to the nozzle 5 of the hearth bottom, and further extends downward. Pipe 7 for introducing gas into the side plates 2, 2' of the body.
7' is a melt-spinning nozzle mask.

の圧力を有する気体例えば空気をこのマスク内に送入す
ることにより、流下する溶融物は保温されつつ、円筒体
内に誘引され適当の太さのフィラメントに延伸され細い
繊維に紡糸される。The above-described melt-spinning nozzle mask according to the present invention is attached to the lower part of the nozzle plate through its side plate, and then a gas such as air, which has been preheated to a constant temperature and has a constant pressure, is introduced into the mask from a pipe provided on the side plate. By feeding the molten material into the cylindrical body, the flowing melt is kept warm while being drawn into the cylindrical body, drawn into filaments of appropriate thickness, and spun into thin fibers.
即ち導入される気体により溶融物の温度の低下が遅くな
ることと、気流による誘引力も加わるので紡糸量は増加
し、かつ細い繊維が得られる優れた効果を発揮するもの
である。That is, since the temperature of the melt is slowed down by the introduced gas and the attraction force due to the airflow is also added, the amount of spinning increases and thin fibers can be obtained, which is an excellent effect.
この場合、気体は一種の潤滑剤の役目をなし、溶融物に
その表面張力と重力を自由に発揮さすものである。In this case, the gas acts as a kind of lubricant, allowing the melt to freely exert its surface tension and gravity.
本考案に使用するノツズルマスクは通常鉄板で製作され
、円筒体の直径はガラスの場合、ノツズル出口の約１．
５〜２．０倍が適当であり、又長さは５〜１５倍が適当
である。The nozzle mask used in this invention is usually made of iron plate, and the diameter of the cylindrical body is about 1 mm of the nozzle exit if it is made of glass.
A length of 5 to 2.0 times is suitable, and a length of 5 to 15 times is suitable.
なお空気の温度は１００℃以上が有効であり、圧力は０
．０１〜０．８ ｋｇ／ｃｍ２（ゲージ）の範囲が適当
である。Note that it is effective for the air temperature to be 100°C or higher, and the pressure to be 0.
．． A range of 0.01 to 0.8 kg/cm2 (gauge) is suitable.
又導入気体として空気の代わりに他の気体、例えば窒素
を使用することができる。Also, other gases, such as nitrogen, can be used instead of air as the introduced gas.
又垂下するフィラメントに化学作用を行なうために、例
えば酸素、水素或いは炭酸ガスを使用することもできる
。It is also possible to use, for example, oxygen, hydrogen or carbon dioxide gas to effect a chemical action on the depending filaments.
本考案によるノツズルマスクによるときは、フィラメン
トの径は数百ミクロン程度、繊維は２５μ以下を容易に
能率良く製造することができた。When using the nozzle mask according to the present invention, it was possible to easily and efficiently produce filaments with a diameter of several hundred microns and fibers with a diameter of 25 μm or less.
