The invention concerns a method of threading in a thread into a texturing nozzle known as such, and an apparatus for implementing the method. The texturing nozzle is brought from a working position into a threading-in position for threading-in, in which position a treatment chamber provided with slots and located upstream from the outlet opening of the texturing nozzle is subject to a vacuum for sucking in a thread brought to a position in front of the inlet opening of the texturing nozzle.

Method of threading a thread into a texturing nozzle

A process for introducing one or more threads into a texturizing nozzle, in which the texturizing nozzle, together with the inlet member, is first brought into a position in which the thread is led transversely past and in the immediate vicinity of the texturizing nozzle, the thread is sucked against the nozzle with the orifice of the inlet member enlarged, immediately after being sucked against the texturizing nozzle the thread is cut beyond the nozzle so that the cut end is sucked back into the nozzle, the suction supply required for the sucking-in is replaced by pressurized fluid texturizing medium, and the cross-section of the inlet orifice of the texturizing device is reduced to a value advantageous for steady state operation. An apparatus for carrying out the above process, comprising a pivotable texturizing nozzle with an inlet member of variable cross-section, and a suction device which permits the pressure to be reduced, relative to atmospheric pressure, at the inlet member of the texturizing nozzle, is also disclosed.

Process for threading up a rapidly travelling thread in a texturizing

A process for texturizing bundles of filaments of synthetic high molecular weight materials at high speed, wherein the filament bundle is passed through a feed nozzle and is then brought into contact with a hot gaseous medium which is undergoing a vortical motion and has acquired a vortex angle of from 10.degree. to 70.degree. as a result of passage through a vortex chamber, is then heated by the fluid medium in a downstream tubular chamber and is subsequently fed to an expansion stage to produce the crimp, and apparatus for carrying out this process.

Process and apparatus for texturizing filament bundles

Apparatus for threading up a texturizing nozzle

A process for the simultaneous texturizing and entangling of filament bundles by treating filament bundles of synthetic, high-molecular weight materials with a heated fluid in two tubular treatment chambers, in which process spatial or periodic irregularities are produced, in the treatment zones, in the flow of fluid and/or filament bundles. Preferably, a certain range of values of a volume mass flow factor is adhered to.

Simultaneous texturizing and entangling of filament bundles

Integrated process for continuous spinning, drawing and texturizing of synthetic linear high molecular weight polyamide polymers, in which the following steps are effected in immediate succession:

Integrated spin-draw-texturizing process for manufacture of texturized

Apparatus for crimping filaments using turbulent heated fluids to which the filaments are exposed in two treatment chambers connected to one another. The first treatment chamber is constructed in two parts, the parting plane between the two parts is stepped and the filament guide means are intersected by the parting plane. The filaments are easy to introduce and the operating temperature need not be reduced in the event of any filament breaking.
