Description

The invention also relates to a fancy yarn formed by a flow of pressurized medium and having longer thickened sections in the direction of its longitudinal axis, not consisting of a base component comprising at least one silk of chemical fibers and an effect component also containing at least one silk of chemical fibers, production.

Various methods of producing fancy yarns are known, characterized by longer thickened sections, for example on the principle of differently elongated volumetric multi-component filament yarns. Said production method comprises feeding the yarn into a mechanism in which it takes on the character of a fancy yarn by means of swirling opposing streams of the fluid used.

According to another known principle of manufacture, which is described in British patent no.

No. 426,876, the formation of a mixed effect thread with thicker sections is based on a different lead of feeding two kinds of thread into the turbulent chamber. The first, core thread, is supplied at zero advance so that it does not become more bulky. The second effect-forming yarn is supplied in a positive advance by the fluid flow, while the fluid is sucked from the inlet and outlet vents of the turbulent chamber, thereby producing an effect on the yarn as the resultant yarn travels through the fluid flow. In this process, the turbulent chamber loops and forms randomly incident coils caught on the core thread.

The number of the silk effect component and their order in feeding to the forming nozzle together with the base component corresponds to the number and arrangement of the grooves on the sample tray.

The method of making the effect thread of the present invention can be advantageously applied to mechanically shaped unsupported hybrid threads under conditions where the effect component containing the chemical shrinkage fibers of the lower shrinkage is fed in a smooth section of the effect thread across the full perimeter of the patterning galley. chemical fibers of higher shrinkage. Both components are jointly subjected to a mechanical shaping process by a pressurized fluid stream to interweave the fibers of the base and effect components and to form arcs and loops on the fibers of the effect component. In the thickened yarn section, the effect component is drawn into the forming nozzle together with the base component at certain intervals and in advance many times greater than its constant advance corresponding to the smooth section to form a longer thickened section along the longitudinal axis of the effect thread. the thread is subjected to a heat-shrinking process to fix and enlarge the arcs and loops formed and then wound onto the bobbin body.

The filament according to the invention has, on the surface of the smooth sections, predominantly the fibers of the basic component or of the fibers. chemical fibers with higher shrinkage, while on the surface of longer thickened sections predominantly fibers of the effect component or fibers with lower shrinkage.
