Method and device for texturing yarns and the like.

The invention relates to methods and apparatus for texturing yarns and the like, where at least two threads are twisted together and their twists are fixed. In the context of the invention, texturing is a change Understand the yarn structure by crimping and the like, thereby giving the yarn an increased elastic stretchability and primarily to convey an increase in the yarn volume. Such texturing can be done with mechanical, chemical and thermal agents * be it individually or in Connection with each other, are brought about! *

In practice, texturing has so far been predominant in the case of fully and semi-synthetic yarns, for example, with the help of the false twist process, the stuffer box process and the like. Most of the methods for texturing such yarns are based on the smooth yarn Forced arches or other deformations are thermally fixed. Also for yarns, threads or twines made from native fibers (e.g. cotton) some processes are well known with the help of which texturing will be possible should, with the aim that these yarns increase their normal tendon, as well as an increase in its volume (Bulkiness), (but at least one so-called struk-l tural deformation, for example in the form of fixed arches or crepe character. *

In one of these processes, cotton yarns are raised Elasticity through treatment of twinned yarns with. cross-linking synthetic resins, Eitzafixlerung in this twisted up state and then turned back manufactured. This is intended to keep the yarns fixed in a spiral or crimped shape.

Finally, 1st - has been suggested elasticity of the cotton thread to shrink strongly by tension-free mercerization and with subsequent vaschen and Drying without increasing again stretching. ™

However, all these procedures lead to the native area an only slight increase in volume or elasticity in relation to the texturing of fully or semi-synthetic yarns -

The invention is based on the object of developing a texturing method and a device suitable for carrying out the method, with the aid of which j it is possible in a simple manner yarns, loads, twines and the like. Any kind of texturing within the framework of a controllable discretion, without the severe limitations known procedures to have to accept. In particular, the object of the invention extends to the texturing of yarns and the like, made from native fibers, primarily cotton.

To solve the problem, the invention is based on twisted threads. The essence of the invention consists in that one of the threads to be twisted is made of a material that can be removed from the twisted bond using a suitable solvent. If the thread undergoes a corresponding fixation process beforehand, it remains after the one is detached The other thread, immune to the solvent, in the form impressed on it by the twisting.

How this shape is created in detail depends on the thread construction (twists, thread thickness) the type of individual threads that are brought together to form a twisted bond and the type and intensity of the fixation. For the purposes of the invention, at least one thread that is soluble in the solvent has one or more insoluble threads Threads so twisted that the insoluble thread is the basis for the later shaping (crimping or construction).

By changing the degree of twist (twist or speed) a change in the building ohmic can be brought about.

The building reliability also depends on the mutual cross

cutting behavior of the threads coming to the third twist. This approach is of course not only applicable for 2-strand threads, but also for 3 and multiple threads. The only important thing is that of the yarn A portion of yarn in the twisted bond must be detachable.

This thread produced in the usual way is im Bahmen a preferred embodiment fixed Ä

and then subjected to a treatment by solvent. This treatment has the result that the soluble thread is dissolved or removed from the twisted bandage and only the thread or load that has not been attacked by the solvent remains. The remaining threads, which were not attacked by the solvent, can now be transferred to the one that was triggered by the omission of the Penetrate Baden's tree that has become vacant, occupy it, which also creates a structural bulging and an increased elasticity due to the loosening of the thread structure Elongation results.

A large number of variants are available within the framework of advantageous embodiments of the invention. On the one hand, according to the invention, it is obvious that the solvent treatment should be carried out immediately after the fixing process in the yarn

'as it is also expedient on the other hand can be, this treatment on the twisted from the and, if necessary, made of fixed yarn. Ss is also quite possible that to process only twisted yarn first into a knitted fabric, knitted fabric, woven fabric and the like and only afterwards the fixation as well as treatment with solvent in the piece.

These process operations, which are aimed at fixing and dissolving, can advantageously be carried out in the context of the invention with machines such as those used for chemical cleaning and finishing. With the help of these devices, the non-detachable yarns or flat structures can also be removed from the solvent by soaking, spinning and drying. Ss is immaterial, o "o be treated in this device daa finished or semi-finished or the strand or Spulwickel. Vesentlich the purposes of the invention is merely the application of known for purposes other machines for the displayed herein.

In the context of the invention, it can also prove to be advantageous

prove to be effective if the fixation is carried out simultaneously with the twisting in one operation, especially since it is possible to incorporate this fixing process into previously known twisting processes.

In one embodiment, the invention is achieved by twisting soluble threads, yarns or twines, For example, from cellulose, viscose wool, acetate or from other tariff derivatives, alginates, polyvinyl alcohol or from polyamides and other non-toxic substances Threads, yarns or twines marked.

Tone of particular importance is that such yarns made according to the invention from cotton and the like. In their elasticity or elasticity over time do not subside, or only slightly, so see Considerable progress compared to the known texturing processes for native yarns, e.g. with the help of tension-free mercerization, results.

According to the invention, in addition to yarns made of cotton, yarns made of e.g. flat, linen, full or even Texturing mineral substances such as asbestos as well as any kind of icing. The same applies to full and half

After it is possible with the help of the invention, yarns Texturing from a wide variety of materials, which were previously considered unsatisfactory texturable, can The invention also serves as the main proceedings for the Use to achieve special textile effects that cannot be mentioned individually because of their diversity. It is pointed out, for example, that in the context of the invention it proves to be advantageous to dissolve the Thread as a carrier thread through the other thread or threads to be twisted in a known manner, so that the threads which withstand the solvent treatment, later the Rautaforttt show a coat twist without a core. Furthermore, in the context of the invention, reference is made to the advantageous embodiment, according to which, in addition to the at least one thread remaining in the thread to be dissolved S and Z twist threads can be used crosswise. In this way, for example, you can achieve the same or similar building effects with cotton yarns, which can be achieved with full and semi-synthetic threads or yarns were already known.
