摘要:
A fiber guide of the present disclosure includes a yarn-guiding section that contacts with a fiber, and composed of zirconia ceramics, the zirconia ceramics comprising: first particles, each containing zirconia; and second particles, each having conductivity.
摘要:
A fiber guide having an excellent wear resistance against a high-functional chemical fiber is provided. A fiber guide of the invention includes ceramics containing at least crystal grains of zirconium oxide, an average crystal grain diameter of a crystal grain constituting the ceramics being 1 µm or smaller. Since this fiber guide which complies with the above configuration has an excellent wear resistance against a high-functional chemical fiber, it is possible to reduce a replacement frequency of the fiber guide, and improve the production efficiency.

摘要:
In the melt-spinning of filaments, molten polymer is extruded downwardly through circularly arranged holes of a spinneret to from a circular group of filaments. Quench gas and finish liquid are directed outwardly through the filament group. In order to reduce vibration of the filaments as they pass from the spinneret to a lower guide, the filaments are passed through an upper guide which deflects the filaments inwardly towards the longitudinal axis defined by the filament group.
摘要:
A fiber guide according to an embodiment of the present disclosure comprises a contact surface with a fiber having a ratio of Ra1/Ra2 that is 0.5 or more and less than 1.0, where Ra1 is an arithmetic mean roughness in a feed direction of the fiber and Ra2 is an arithmetic mean roughness in an orthogonal direction orthogonal to the feed direction.

摘要:
Anlage zur kontinuierlichen Herstellung einer Spinnvliesbahn aus Filamenten, mit zumindest einer Spinnerette, einer Kühlkammer, einer Verstreckeinheit und einer Ablageeinrichtung zur Ablage der Filamente zur Spinnvliesbahn. Zwischen der Verstreckeinheit und der Ablageeinrichtung ist zumindest eine Filamentführungseinrichtung mit einer Mehrzahl zur Verstreckeinheit hin offenen Filamentführungsspalten vorgesehen. Die Filamentführungseinrichtung bzw. zumindest eine Führungskomponente der Filamentführungseinrichtung ist mit der Maßgabe bewegbar, dass die Filamentführungsspalte bzw. ihre verstreckeinheitsseitigen Öffnungen verlagert werden, insbesondere quer zur Förderrichtung der Spinnvliesbahn verlagert werden, so dass den entlang der bzw. durch die Filamentführungsspalte geführten Filamente bzw. Filamentbündeln bei der Ablage auf der Ablageeinrichtung eine Querorientierung bezüglich der Förderrichtung der Spinnvliesbahn auferlegt wird.
