Übersetzung für "Spinnfaden" in Englisch

The spun filament is stretched in air.

Spinning yarn 7 is positioned in front of the so-called yarn reserve groove of empty tube 10 .

The high glass transition temperature compared with the polyester ensures rapid solidification of this fibril structure in the spun filament.

For silk production, the cocoon ? together with the pupa inside ? is boiled and the silk filament is then unravelled.

DE 555183 relates to spinning vessels for wet spinning, wherein a spinning yarn runs perpendicularly through a number of baths.

For test purposes, drawable yarn is placed under the microscope in such a manner that the individual filaments are well visible.

For test purposes, part of a drawable yarn is placed unter the microscope in such a manner that the individual filaments are well visible.

A filament is ruptured at room temperature in a tensile tester using a clamping length of 100 mm and a clamp speed of 400 m/min.

The same process was carried out on a filament having a birefringence of 0.033 and an SRmax of 90%, which had been spun with a windup speed of 3000 m/min.

The application describes a process with which, through modification of the previously used spinning conditions, a high takeoff speed is used to obtain a filament which has high strength values after stretching.

According to German Auslegeschrift 1,288,734, the spinning conditions for this purpose need to be such that the tensions acting on the solidifying filament are extremely low and that the filament is consequently distinguished by a very low molecular orientation.

The strengthened spinning thread can either be drawn directly or, following winding up or spooling, in a separate step using standard methods.

This curling tendency of the twisted yarn can only be counteracted, as in the spun yarns, by a ripening process or artificial fixation, i.e., a moisture/heat treatment.

In addition, it should be possible to produce the HMLS filaments in a customized manner for the particular application by adjustment of the birefringence in the spun filament substantially independently of the spinning take-off speed.

Through the choice of a favourable viscosity ratio, a particularly narrow particle size distribution of the additive in the polyester matrix is achieved, and by combining the viscosity ratio with a flow activation energy which is significantly greater than that of the polyester (PET about 60 kJ/mol), i.e. greater than 80 kJ/mol, a fibril structure of the additive is obtained in the spun filament.

Only for sampling in order to determine the birefringence was the spun filament fed to a wind-up unit after just this 1st pair of godet rolls.

Surprisingly, it has been found that the additive properties according to the invention that have been described and the associated specific fibril structure in the spun filament result in high efficiency, i.e. the amount of additive to be used is particularly small compared with the prior art, based on the desired effect.

Increases in elongation can thus often be achieved in the spun filament, but inadequate increases in the stretching ratio are achieved on stretching in the fibre stretching stage, and the effect on the spin factor remains insignificant.

Even though the process described in paragraph 3 supra claims to combine the three processes spinning, twisting, and winding into a single continuous process, it is obvious that this method for the reasons disclosed above cannot completely fulfill this claim because it is always necessary in a first method step, for example, with a conventional ring spinning machine, to produce a spun yarn which is wound on the ring spinning machine to a cop that is then, according to the method described in paragraph 3 supra, twisted together with the predrawn roving.

When both yarn portions are to have a same twist, as is expected from a balanced twisted yarn, then this can only be achieved when the twist of the spun yarn of the spun base yarn body resulting from the spinning process is canceled during the second method phase, i.e., during the twisting phase, so as to be completely canceled.

During the twisting process the spun fibers wound onto the spun yarn body are removed from the yarn body in a second process step by building a balloon and guided through the hollow spindle axles of the two hollow spindles to the winding device.

In FIG. 2, in the left half of the drawing, the spun yarn F2 is represented such that it extends across the guide pulley 17 in the manner in which it is being guided after the joining process.

A spun yarn F1 is guided, after the joining process, from the first spinning rotor 1 through the fiber removal tube 31 across the guide pulley 16 and, after being deflected by 180°, is introduced into the inlet opening 11a of the hollow spindle axle 11.

In the same manner, the spun yarn F2 coming from the spinning rotor 2 via the yarn removal tube 32 is deflected by the guide roller 17 by 180° and is guided into the inlet opening 11a of the hollow spindle axle 11.
