Definitions

  • the invention relates to a preparation method and a device for special chemical fiber, in particular to a method and a device for producing a crimped polyester filament by heating a hot roll. Background technique
  • the method is realized in the following manner: the polyester filaments spun from the polyester spinning machine are grouped, one or more sets of tows are heated by the heating roller, and then the two sets of tows with different heating times are combined and wound.
  • the woven silk cake is used for weaving textiles. Because the physical properties of the polyester filaments are locally changed during the heating process, the fabric woven from the heat treated polyester filaments has the physical properties of natural curl after being treated by boiling water.
  • polyester filaments of the same and different crimping effects can be produced by simply replacing the heating rolls of different diameters or adjusting different heating temperatures.
  • the polyester filaments sprayed from the nozzle of the polyester spinning machine are divided into two sets of tows, and the two sets of tows are respectively wound on the rotating heating roller for one or two turns, and the heated two sets of polyester tow are combined.

Abstract

L'invention concerne un procédé de production de filament de polyester ondulé par enroulement du filament autour d'un cylindre chauffé à la vapeur ainsi qu'un dispositif associé. Le procédé fait appel aux étapes suivantes: les filaments de polyester sont filés à partir d'une filière (1) afin de les séparer en au moins deux faisceaux de filaments (3), lesdits faisceaux de filaments séparés sont enroulés séparément autour d'un cylindre rotatif (2) chauffé électriquement sur un ou deux tours, les faisceaux qui sont chauffés par le cylindre chauffé électriquement sont combinés en un fil et enroulés de manière à obtenir un gâteau (4). Le fil est ensuite transformé en tissu. Les filaments de polyester ou le tissu peuvent produire une ondulation naturelle après que le tissu est traité à l'aide d'eau chaude. Comparé à l'état antérieur de la technique, le procédé de l'invention fait appel à une conception raisonnable, à un dispositif simple et le filament de polyester produit ainsi que le tissu présentent une ondulation naturelle, etc.
