Description

GERMAN

The invention relates to a method for the production of a stocking, the mesh structure of which according to the usual knitting or knitting is mechanically deformed and fixed in the deformed state. In the endeavor to prevent stitching in stockings - especially women's stockings - one has already proposed and applied after-treatments on the finished stocking on various occasions which the mesh structure od by synthetic resin solutions. Like. With a more or less thick film that is to hold the stitches in place. However, the stockings treated in this way have the disadvantage that they are inelastic and do not have a soft hand. In addition, it sometimes gets lost the anti-ladder effect of the film after repeated washing.

After the introduction of linear polyamides as a thread material for the production of fine women's stockings one already has the property of this material to be under the influence of heat and To let steam deform, made use of that by crimping the thread before The processing of a later knitted fabric with a relatively high ladder stitch security wins. However, crimping the thread is difficult and expensive. The most commonly used method, the Bringing crimp by twisting and steaming results in relatively thick threads, which are out of the question for the finest women's stockings.

It is also already known to use individual stitches in knitted or woven fabrics made from polyamide threads to be deformed by stretching and the action of heat in such a way that the distance between the threads is determined Places has been expanded, with the shaped or stretched parts of the threads in the stretched state were fixed. However, this known method was costly and did not result in a completely irregular one Mesh structure. The randomly deformed mesh structure is a prerequisite for a ladder-inhibiting Effect is achieved. One already has ones that extend in the longitudinal direction of the stocking Pinches attached, whereby the knitted fabric was deformed as a whole, but not the individual mesh structure. Therefore, through the known tricks, one could get over the whole the knitted fabric surface extending, randomly deformed mesh structure can not be achieved, so that even this known method does not lead to the ladder-inhibiting effect sought by the invention Effect led, especially since the known crease lines disappeared when putting on the stocking, so that the ladder-inhibiting effect required just then could not be exerted anyway.

Another known method is methods of manufacturing

to first process the smooth, stretched thread into stitches or into a knitted or knitted fabric, to fix it as a knitted or knitted fabric under the action of heat and / or steam, the mesh of the Then pull up the knitted or knitted fabric again

² S and then reel the thread fixed in the form of a loop for subsequent processing. It is obvious that this process - although it can also be used for the finest threads - is extremely expensive.

Compared to this known prior art, the invention proposes a method of production a stocking, the mesh structure of which is mechanically deformed after the usual knitting or knitting and is fixed in the deformed state, which can be carried out in a simple and inexpensive manner, reliably to the desired ladder-inhibiting effect over the entire surface of the so treated knitwear leads and is characterized in that the stocking after

Through the rubbing movement in the water bath, the Of course, softening agents or the like can be added, occur within the mesh structure Mesh deformations, which are the more frequent and extensive, the more violent and longer the rubbing movement takes place in the water bath.

After the treatment in the water bath, the stocking must be steamed or another heat

exposed to the action in order to fix the mesh deformations caused by the treatment in the water bath. The stocking is then dyed and shaped in the usual way, it being expedient to keep the temperatures during the shaping process lower than that which was used to fix the stitch deformations. But even if the temperature during molding or other post-treatment is higher than the temperature when fixing the mesh deformations, these are not lost. It is of course also possible to move the stocking in the water bath, which is necessary to achieve the mesh deformation, only after dyeing, or to bring about the mesh deformation in the dye bath itself. It is only essential that immediately after the formation of the mesh deformation the fixing of the same takes place, whereby the stocking must be in an untensioned state. Since the mesh deformations occur with a certain randomness, in addition to the ladder-inhibiting effect on the finished stocking, a pattern effect occurs which gives the stocking a peculiar appearance. In order to exclude this pattern effect in certain places, e.g. B. on the double edge or in the reinforced parts, these parts of the stocking can be made of a different yarn material or with the addition of a different yarn material which, like the polyamide fibers, is not subject to mesh deformation. In the drawing, the stocking made according to the invention is illustrated. 1 shows a stitch pattern of the new stocking, FIG. 2 shows an overall view of the stocking, and FIG. 3 shows an exemplary embodiment of a stocking in which certain parts of the stocking are excluded from the mesh deformation. The mesh pattern shown in FIG. 1 shows the deformation of individual meshes caused by mechanical processing in a water bath. The meshes 1 are those of normal shape and size. In contrast, enlarged meshes 2 have arisen, which result in a narrowing of adjacent meshes 3. The latter especially contribute to the fact that the Maschenlasuf is inhibited. The mesh deformation forms, as FIG. 2 shows. ίο at the same time an irregular pattern on the stocking. While in the stocking shown in FIG. 2 the deformation of the mesh extends over the entirety of the stocking, individual parts of the stocking can also remain excluded from the deformation. Thus, in the exemplary embodiment according to FIG. 3, only the length 4 is covered by the deformation, while the double edge 5 and a part 6 adjoining it downward and the reinforced heel 7 are excluded.
