DE3126051A1 - Multi-component yarn for multi-coloured velours and process for producing it - Google Patents

Abstract

For the production of multi-coloured velours, especially velour carpets, plushes or velvets, there is proposed a multi-component yarn which contains at least two basic threads (1, 2) running essentially parallel and a winding-round thread (3) wound round these, the basic threads (1, 2) being differently dyed plainly or batchwise, and at least one of them consisting of continuous capillary fibres. There are advantageously two basic threads (1, 2) which both consist of continuous capillary fibres. The production of such a multi-component yarn takes place in that, in one operation, two or more basic threads (1, 2), which consist of continuous capillary fibres and at least one of which is subjected to continuous coloration by plain dyeing or printing, are fed to a hollow winding-round spindle rotating at very high speed, are wound round uniformly with a very thin winding-round thread (3) and finally are spooled continuously in this form at high speed. <IMAGE>

Description

Multi-component yarn for multi-colored velours and processes

for its manufacture The invention relates to a multi-component yarn for multi-colored velours that can be produced from them, in particular velor carpets and plushes or velvet, as well as a method for producing such multi-component yarn.

For the production of multi-colored velours, especially velor carpets with a melange-like appearance, are predominantly colored differently up to now Staple fiber yarns used, but because of their quite complex production and Finishing entails considerable costs. In addition, such yarns are on the Carpet machines are also not easy to process. They also not infrequently lead to banding and similar image effects in the Velor carpet. That is why attempts have already been made to produce velours from endless threads. These Velor production is due to the considerable fluctuations in texturing and dyeability of these yarns poses a very great risk.

The invention is therefore based on the object of a multi-component yarn to create the generation in a relatively simple and cost-saving way streak-free, multicolored velours, e.g. B. appropriate carpets, plush or Velvet, permitted and therefore easy and inexpensive to manufacture and easy to process is. According to the invention, this object is achieved by a multicomponent yarn which at least two essentially parallel, differently uni- or Basic threads dyed in sections as well as a winding thread wound around the latter contains, where. at least one of the base threads consists of continuous capillary fibers. The multi-component yarn advantageously contains two continuous capillary fibers in particular textured ground threads, one of which is continuously uni- and the others are colored differently in sections, such a multi-component yarn allows multi-colored velours to be used in a particularly efficient way, without any stripes or images Way to produce, especially since such a yarn because of the substantially parallel running ground threads is relatively smooth and easily processed over it but above all, it can also be produced simply and inexpensively.

Such a multi-component yarn is advantageously produced in such a way that that in one operation two or more basic threads consisting of continuous capillary fibers, of which at least one of continuous coloring by unicolouring or Printing is subjected to a wraparound hollow spindle rotating at very high speed fed, evenly wound around with a very thin winding thread and in this shape can eventually be wound up continuously at high speed.

Such hollow winding spindles which enable the winding of threads, which can rotate at a very high speed, namely up to 60,000 rpm, are known. They have already been used to create endless threads in part also in connection with warped fuses to be wound together in this way To produce nub, loop or flame yarns. Usually one of the ground threads or rovings to be used at the winding point with a higher Speed is supplied, whereby the corresponding loops are then formed. So this is not a multi-component yarn intended for velours.

The plain dyeing or color printing of the parallel continuous threads or Ground threads can be made immediately before winding, with one of them being expedient Base thread with light color is continuously splashed, while the other base thread is printed differently in sections or is sprayed with paint. This will be the yarn finishing costs kept very low. In addition, this finishing process in the smallest of spaces and directly in Connection with the winding process carried out. This also results in high cost savings compared to the known Double twisting of carpet yarns, which is done at a much lower speed.

Stripes in the velor caused by differences in the color affinity of the Yarn can be eliminated by the new multi-component yarn, once by the fact that one is responsible for the coloring of the various endless threads selects strong chiaroscuro contrasting colors and, on the other hand, the combination two space lengths, namely a Uni-Space and a Short-Space, which is a good one Ensure de-pictorialization.

The new multi-component yarn can also be used for fine-tufted carpets advantageously used and processed on coarser tufting machines. By the deepening of two or three finer threads, which are wound together, is created also with a coarser tufting machine that can be used for these threads, e.g. B. one those with 1/8 inch graduation, the effect of fine graduation, e.g. B. like a 5/64 machine. The particular advantage here is that coarse velor machines in large numbers are available and velor tufted carpets on them are much cheaper can be produced as the performance of these machines in relation to the Fine division machines is considerably higher.

Various modifications are within the scope of the present invention possible. In addition to its endless base threads, the multicomponent yarn can also also staple fibers in the form of a stretched continuous fuse or contain knobs fed in at intervals, which are also wrapped by the winding thread are. Furthermore, the endless ground threads and / or the wrapping thread can be antistatic be or made of threads with different electrical charges, such as. B. polypropylene and polyamide, which have an antistatic effect. Furthermore, the Endless basic threads consist of elastomer or shrink threads. It is also essential that the endless ground threads have a different luster, namely on the one hand can be matted and on the other hand glossy.

There are also various aspects of dyeing the multicomponent yarn Modifications or configurations are possible. So it can be of advantage that for a particularly non-drying coloration foamed printing liquor or hot Dye liquor is used. It is also possible that for the coloring of the or the base threads, in addition to the dyes, also such products are applied, a reservation or deepening of the color of the job sites for the later piece coloring cause. Foamed printing pastes can also be used for coloring the basic threads with transfer dye are used, which are later fixed with hot air will. Finally, after being wound up, the yarn can undergo a dye fixation subjected by post-treatment in a vacuum damper or by high frequency will.

In the drawing, an advantageous embodiment is a for the production of velor multi-component yarn on an enlarged scale shown.

This yarn essentially consists of the two endless threads or Ground threads 1, 2, which run essentially parallel to one another and only are held together by the fine winding thread 3. Each of the ground threads 1, 2 is textured and consists of continuous capillary fibers.

While the basic thread 1 with a light color is continuous or continuous is splashed and has a matt appearance, the basic thread 2 is in sections differently colored or printed, so in space-dyeing art. He owns one slightly glossier appearance. Both ground threads 1, 2 are before passing the winding hollow spindle, so the winding around the thread 3, on appropriately arranged and acted upon Paint spray nozzles, for example, of a Hacoba dyeing machine.

All known endless filaments, such as in particular made of polyamide, polyester, polypropylene or polyacrylic, where the staple fibers that may still have to be added in the form of slivers or nubs the same materials or made of wool or cotton. For the winding thread 3 is advantageously also a continuous filament yarn from the above mentioned synthetic fibers are used. The base threads and the winding thread can optionally also not be textured.

The new multi-component yarn is suitable for the production of the most diverse Velours or pile articles intended and suitable, e.g. B. for tufting, web, double raschel, Knitted and rough velours. In particular, it is suitable because of its comparative properties smooth nature and its too Stripes and images in the Finished product leading properties for velor carpets, but also for upholstery, Decorative and clothing plushes as well as for velvet.
