Needled mesh panels

Akso Gut H Huppertal

The innovation concerns a · Stitched web made of endless chemical threads.

Mesh panels made of endless chemical threads, i.e. endless artificial silk threads and / or yarns and / or twists or threads * Yarns or twisted threads made of! synthetic polymers are made, have a poor feel Stability and have only low opacity

In order to remedy these disadvantages, attempts have been made to knitwear compress by shrinking. But you also set textured e yarns to increase the opacity of the threads and to improve the grip of the goods} here it turns out that it is only possible to a limited extent for these Masohenstoffbahnen to have a woolly fiber-yarn-like surface.

The purpose of this application is to remedy these disadvantages and to create a mesh panel consisting of endless chemical threads create that is stable and woolly to the touch, has good coverage and a fiber-thread-like surface.

It has now been found that giving the product a woolly to the touch, Btandfeste, deck strong mesh fabric with fasergarnähnlicher surface of endless threads that from the processed for mesh fabric chemical threads capillaries cast out aind _t dl "partly looped and / or partly torn from the surface of chemical threads stick out.

To solve this problem, a mesh fabric web consisting of endless chemical threads is passed through a needle machine in which it is pierced by a large number of needles which are provided with barbs, so-called beards. The piercing needles take with their barbs individual capillaries, push them out of the yarn structure partly into the inside and partly beyond the surface of the mesh web, forming loops or protruding fiber ends » * <± which tear the capillary threads when piercing .

The single threads of endless chemical threads are under capillaries, see below

The reed fabric web according to the invention can also be passed through a double-needle machine in order to achieve the effect of the needling to be applied to the fabric in one operation.

The K ,schenstoffbahn can be made from endless chemical threads of all origins and / or be produced in mixtures thereof. Particularly good «Properties are achieved with such mesh fabric webs, those made from endless filaroent blended yarns such as Made from polyanide-Fden and rayon threads. It Both smooth and textured yarn can be used.

Needling has the advantage over roughening a knitted fabric web that the capillaries pushed out to form the downy surface by the barbs attached to the needle shaft in an axial view and offset in the circumferential direction come from the total area of the knitted fabric depth, while with hooding only the capillaries of the fabric surface be taken by the rough sets * the needle process has the additional the Vorteilf tHe djareh the S Clin genetically or looping a compression takes place from the entire range of knitwear depth, di "ffäjps fill ig he is. SMhrsnd in the present. Fall siife

using a suitable needle machine, a double-sided treatment of the Haschenstoffbahn can be carried out in one operation at the same time can, this is not possible with rough goods; here it is necessary The £ dl * HÄ * chss »fabric web in at least two work processes is roughened.
