EP0701016A1 - Non-run stocking - Google Patents

Abstract

The stocking is made from two filaments - polyamide and elasthane, formed into linked loops in a single weaving operation without the use of special chemicals. The two filaments are joined together in double loops, with the elasthane tending to draw the loops together. The resulting material is more compact and supple to the touch.

Description

THE MESH IN THE PRODUCTION OF WOMEN'S STOCKINGS

It is an intertwining of curvilinear threads and a single constituent element is sufficient for the formation (by means of needles and plates) of a mesh fabric thus replacing the traditional system for creating the mesh with the weft ( horizontal) and the (vertical) chain of the BUSINESS.

Each mesh is linked to the next by means of an inter-mesh. A mesh is made up of the upper arch called head or needle loop, two lower semicircles called base of loop or loop of plates and two wings or rods which connect the head to the feet. (see diagram A - Pl. I / 6)
Diagram A represents a mesh where N ° 1 indicates the loop formed by the needle, N ° 2 the rectilinear rods, N ° 4 the loops formed by plates which joined together, form the inter-mesh N ° 3.

SMOOTH MESH

The main type of interlacing used in the production of women's stockings is smooth knit (see diagram B - Pl. II / 6)
From the graphic representation, we can clearly note how the smooth mesh is remarkably well endowed with elasticity because the inter-meshes, not being blocked, allow the wire to slide freely, in any direction, according to the type of external stress (see diagram B - Pl. II / 6)
The elasticity acquired from this system to create the mesh has, however, a considerable handicap: the mesh that spins.

During the breakage of a thread at a generic point, there is created, because of the nonexistence of blocked inter-meshes, a shooting which is repeated continuously (in the vertical direction). (see diagram C - Pl. III / 6)

FIXED INTERLOCATIONS

Thus are called the crisscrosses which, by their own constitution, oppose the mesh which file fixing the heads of the meshes.

The methods, in use, are based on meshes in the form of Loops, Plated, Transported, Throwns, etc ... which, in any way, "close" the mesh that spins, opposing a barrier to flow stitches. The most widely used system in the production of women's stockings is the loop-shaped mesh.

LOOP-SHAPED MESHES (Selections 1: 1. 3: 1; 7: 1 etc ...)

• a) obligatoirement engagée dans un parcours fractionné et non rectiligne;
• b) comme sur le schéma D, il existe des hauteurs différenciées des mailles qui ont, pour conséquence, des rétrécissements des formes à bouches sur l'inter-maille. (voir schéma D - Pl. IV/6)

Bien qu'ayant atteint un bon niveau d'indémaillabilité, puisque l'ouverture du canal étroit sur l'inter-maille freine, à cause du frottement majeur, la dynamique du fil, ce produit présente un bas coefficient d'élasticité. Un autre inconvénient du filet susmentionné est dû au toucher du tissu, très crépu, en comparaison avec la maille lisse.These selections, which are arranged in a checkerboard pattern, slow down spinning because:

• a) obligatorily engaged in a divided and not straight course;
• b) as in diagram D, there are differentiated heights of the meshes which have, as a consequence, narrowing of the shapes with mouths on the inter-mesh. (see diagram D - Pl. IV / 6)

Although having reached a good level of non-runability, since the opening of the narrow channel on the inter-mesh brakes, because of the major friction, the dynamics of the wire, this product has a low coefficient of elasticity. Another disadvantage of the aforementioned net is due to the touch of the fabric, very frizzy, in comparison with the smooth mesh.

WATERPROOF stockings and tights "LIFE" MODEL

The systems of current technologies have made it possible to deepen the studies of the traditional non-flammable and we have arrived to create a new model of mesh which we have called "THE INDEMAILLABLE LIFE", extraordinary in all points, because it presents a perfect fision qualities of smooth knit and traditional non-slip.

The formation of the "SYSTEM LIFE" mesh was carried out in the following way: While in the mesh fabrics with weft (the traditional non-slip) only one wire successively forms the meshes, in the model "LIFE" the chain of two threads (polyamide and elasthane), technically called plated, form the meshes simultaneously; in practice, with the only weaving operation, without the use of any special chemical and without the use of a thread different from those used in the normal production of stockings and tights, we manage to create a double loop called, in fact, "Throw" mesh. We can clearly see, in diagram E (see Pl. V / 6), the aforementioned concepts and the specific function of elasthane which tends to approach the mouths of smooth mesh ( tightening effect ) , thus blocking the continuation of the shooting . At rest, the LIFE non-slip, for example a pantyhose, is shorter and is, to the touch, more compact and more flexible compared to the traditional non-slip but, compared to the latter, it has notable characteristics of stretch and elasticity which improve the quality and, above all, the threading.

Explanation of diagram E: the black thread, in the drawing, corresponds to that of elasthane, while the red thread corresponds to polyamide. These two work in smooth knitting weaving.

On the real photo, (see diagram F - Pl. VI / 6), you can see a 20 '' enlargement of the mesh fabric that we made. We clearly see the inter-meshs tightly at the ends of the elastane and polyamide threads; they descend in smooth mesh until they form real and clean "diamonds" at the end of which bind the loops of the second polyamide worked with the net. In the event of breakage of one or more threads at a generic point of the weft, the friction which occurs at the point of meeting of the threads prevents the dissolution of the flanges and the enlargement in any direction of the shooting.

Nota Bene

In our diagrams, all the graphics marked with the letters MC are according to the C method and all the graphics which are marked with the letters MT are according to the Tremelloni method.

Summary of the patent "Le bas Indémaillable" (LIFE THE INDEMAILLABLE AND LIFE RUN FREE and LIFE NEVER RUN)

Thanks to this invention, if a hole is made in a pantyhose or a stocking that cannot be spread, this hole will not extend and the pantyhose or stocking will not spin. A sock-proof stocking or pantyhose that is punctured or worn can be worn normally as it will not spin.
