Title
(EN) MEANS FOR PRODUCING EXTREMELY FINE FILAMENT OF WHOLLY AROMATIC POLYESTER
(FR) MOYEN DE FABRICATION DE FILAMENT EXTRÊMEMENT FIN DE POLYESTER TOTALEMENT AROMATIQUE
(JA) 全芳香族ポリエステル極細フィラメントの製造手段
Abstract
(EN)
A means for producing an extremely fine filament of a wholly aromatic polyester and a non-woven fabric comprising the filament, characterized in that a tensile force of 30 MPa per single yarn is imparted to a wholly aromatic polyester filament and the filament is heated by a infrared ray flux, to thereby form an extremely fine filament which has been drawn at a draw ratio of seven or more, exhibits high molecular orientation and has a size of 20 μm or less, and in that a non-woven fabric comprising extremely fine filaments of a wholly aromatic polyester is produced through piling up the above drawn filaments on a conveyer. The above means allows the production of a drawn filament of a wholly aromatic polyester and a non-woven fabric comprising the filament without the need for an apparatus being special, highly precise or of high level, with the use of a simple and easy means.
(FR)
L'invention concerne un moyen de fabrication d'un filament extrêmement fin de polyester totalement aromatique et d'un tissu non tissé comprenant le filament, caractérisé en ce qu'une force de traction de 30 MPa par simple fil est imprimée à un filament de polyester totalement aromatique et le filament est chauffé par un flux de rayons infrarouges, pour ainsi constituer un filament extrêmement fin que l'on a étiré à un rapport supérieur ou égal à sept, présentant une orientation moléculaire élevée et une taille inférieure ou égale à 20 µm, et en ce qu'un tissu non tissé comprenant des filaments extrêmement fins de polyester totalement aromatique est obtenu par empilement des filaments étirés ci-dessus sur un convoyeur. Le moyen ci-dessus permet la fabrication d'un filament étiré de polyester totalement aromatique et d'un tissu non tissé comprenant le filament sans recourir à un appareil spécial, extrêmement précis ou de niveau élevé, en utilisant un moyen simple.
(JA)
全芳香族ポリエステルの延伸されたフィラメントおよびそれからなる不織布を、特殊で高精度・高レベルな装置を必要とせずに、簡便な手段によって製造可能にすることにあり、全芳香族ポリエステルフィラメントに単糸あたり30MPa以下の張力が与えられ、赤外線光束によって加熱されることによって、7倍以上に延伸され、高度に分子配向された、20μm以下の極細フィラメントが得られ、また、その延伸されたフィラメントを、コンベア上に集積することで、全芳香族ポリエステル極細フィラメントの不織布が得られることを特徴とする。
