BRIEF DESCRIPTION OF THE FIGURES

3 . 4 FIG. 12 are schematic block diagrams illustrating detail aspects of embodiments of the method of producing a yarn or sewing yarn according to the present invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Hereinafter, embodiments of the present invention will be described. All embodiments of the invention and also their technical features and properties can be isolated individually or combined randomly combined with each other arbitrarily and without restriction.

Structurally and / or functionally identical, similar or identically acting features or elements are referred to below in connection with the figures with the same reference numerals. Not always will a detailed description of these features or elements be repeated.

First of all, reference is made to the drawings in general.

The present invention also relates, in particular, to staple fiber yarns of carbon and their production, and to methods and possibilities for improving the properties of CF rovings and CF staple fiber yarns, in particular also for use in elastomers, thermoplastics and thermosets, eg. B. in phenolic resins.

This leads to tensile forces in the process, which can have a negative effect on the finished product. Due to the loads, the filaments 20 damaged and thus reduced the mechanical strength. It can also form process disturbances, z. B. in connection with a yarn breakage or the like.

With the help of a twist in the yarn 10 the surface can be increased, this rotation serves to protect the yarn composite. However, here too, the processing is limited. The filament yarns have a very high strength, but a low elongation. If, on the other hand, you produce a staple fiber yarn, ie spun yarn 10 made of staple fibers 20 with limited length, so can a yarn 10 produce with higher elongation.

As a raw material for the stretch-broken staple fiber yarn, a carbon roving with a high filament number can be used. The production of a 1 K roving with a filament diameter of or below 6 microns, however, is very costly.

Carbon fibers have a high strength, but unfortunately also a low ductility. For this reason, carbon fibers in textile processes can only be processed comparatively slowly and at relatively high cost.

It is also an object of the invention, a coating for carbon fibers 20 , Yarns 10 made of stretched fibers 20 or Panox 20 , as well as other brittle fibers that improve the processing properties.

The improvement can be measured inter alia on the basis of the fiber abrasion, the number of thread breaks, and the processing speed. In this case, an improvement is then achieved in consequence also in the sewing and knitting processes. Such sized yarns can be woven more effectively, resulting, among other things, in higher productivity.

An embodiment of the surface treatment can be based on the following aspects according to the invention:
The use of an elastic sizing with a low glass transition temperature for coating fibers 20 and yarns 10 results in a more suitable surface that ensures improved processability.

Self-crosslinking carboxylated styrene-butadiene copolymers, which crosslink in a thermal drying process, have proven particularly suitable.

In addition to a very smooth surface, in particular the electrical contactability of the fibers is an interesting property. Here, the use as a heat conductor in conveyors, as or in hoses, conveyor belts, heatable fabrics, etc. conceivable.

Due to the flexibility, a gentle shear transfer between the fibers 20 and thus a good introduction of force in the entire strand 10 or the whole yarn 10 guaranteed.

This procedure is also suitable for the treatment of all fiber types, but especially of carbon and ceramic fibers.

Furthermore, a good compatibility with elastomer matrices can thus be ensured.

With regard to the improvement of properties of CF rovings and CF staple fiber yarns, in particular for use in elastomers or thermoplastics, in particular the improvement of the process properties by abrasion reduction and / or abrasion prevention is realized, in particular in structures, the emergence by braiding, sewing, Weaving or the like.

The avoidance of friction between single filaments, which is also referred to as internal friction, is made possible by a partial or full coating, impregnation and / or wrapping of a single filament or portion of a single filament with a thermoplastic or a corresponding other material which reduces friction. As a result, improved stability is achieved, especially under dynamic load. This can be in the application z. As elevator cables, drive belts, conveyor belts or the like relate.

Furthermore, through the impregnation, coating and / or coating, an improved integration of a CF roving, CF staple fiber yarn or the respective individual filaments in matrix systems, eg. As rubber, thermoplastic and / or thermosetting plastic, possible. Furthermore, an improvement of the transmission of force, thrust and / or pressure can be achieved by such impregnation, embedding and / or coating.

According to the invention, corresponding methods of introducing thermoplastic fibers are used 20 and / or materials in continuous rovings or filament yarns. Since such processes can also take place with the supply of heat, it is achieved in such embodiments that the thermoplastic melts and completely incorporates the CF filaments. The complete integration and protection of the filaments 20 or filament sections 20 reduces internal friction among each other, thus increasing the dynamic strength of the product.

An impregnation 40 and / or coating 30 the fibers 20 , Fiber groups 25 or the yarn 10 On the one hand reduce or prevent the formation of dust by abrasion, on the other hand, but also the adhesion of existing or existing dust to the fibers 20 , the fiber groups 25 or the yarn 10 as a whole.
