Description

The invention relates to the production of textile materials and for the manufacture of diagonal weave fabrics produced on weaving machines equipped with remise lifting carriages.

There is a method of producing twill weave fabrics in which the direction of the lines of the base twill is changed across the width of the fabric by changing the sign of the vertical shift of the overlap to the opposite after a given number of warp threads (see Kutepov OS, Structure and design of fabrics. M .: Legprombytizdat, 1988 , pp. 40-41).

The reasons that impede the achievement of the technical result indicated below when using the known method include the fact that in the known method it is impossible to obtain strips of the required relief inherent in diagonal weave fabrics on the fabric surface.

The closest method of the same purpose to the claimed invention in terms of features is a method for producing diagonal weave fabrics, in which relief strips of various widths are created on the surface of the fabric, going in a constant direction, adopted as a prototype (see Kutepov O.S. Structure and design of fabrics M.: Legprombytizdat, 1988, p. 43-45).

For reasons that impede the achievement of the technical result indicated below when using the known method adopted as a prototype, the known method cannot change the direction of relief strips running along the surface of the fabric, only the width of the strips can be changed by changing the length of the main floorings of the base twill, or the angle of inclination of the strips, changing the magnitude of the used shift of the floors.

The essence of the invention is to expand the assortment of diagonal weave fabrics by changing the direction of the relief strips across the width of the fabric.

The technical result of the proposed method for producing diagonal weave fabrics is to expand the assortment of fabrics by creating new diagonal weaves with embossed stripes that change their direction along the width of the fabric. As a result of this, the effect of alternating longitudinal sections consisting of relief strips going from the bottom up to the right and strips directed from the bottom up to the left is obtained on the surface of the fabric. Such diagonal weaves can be called broken diagonals at the base.

The specified technical result in the implementation of the invention is achieved by the fact that in the known method for producing fabrics of diagonal weaves on the surface of the fabric create embossed stripes of different widths.

The peculiarity lies in the fact that the direction of the relief bands along the width of the fabric is changed due to a change in the sign of the vertical shift of the ceilings to the opposite after a given number of warp threads.

The drawings show: FIG. 1 shows a basic diagonal weave obtained in a known manner; figure 2, 3, 4, 5 shows the diagonal weave obtained by the claimed method.

Information confirming the possibility of carrying out the invention with obtaining the above technical result is disclosed by the example of constructing a diagonal weave of the claimed method, which is performed in the following order:

1. Build in a known manner the basic diagonal weave, shown in figure 1 and having, for example, the following parameters:

- base twill 4/1 + 4/2 + 1/2 + 1/1;

- shift value So = 2;

- rapport based on Ro = 8;

- duck rapport Rу = 16.

2. Set the number of warp threads - Ko = 15, after which they change the sign of the vertical shift, to the opposite, - So = -2.

3. The sizes of the rapports of the new diagonal weave are determined: the weft rapport is equal to the weft rapport of the base diagonal — Ru = 16, and the rapport based on the basis is determined by the number of warp yarns, after which the shift direction is changed — Ro = 2 · Ko-2 = 28.

4. Build on the main threads a new diagonal weave, shown in figure 2. In this case, the first fifteen (Ko) main threads are built along the basic diagonal, and then, starting from the sixteenth (Ko + 1) thread, the construction is carried out in the reverse order, that is, the sixteenth thread repeats the fourteenth main thread, the seventeenth - the thirteenth, and so on. The last main thread of rapport is always the same as the second thread.

The width of the longitudinal sections on the surface of the fabric, formed by relief bands, inclined in different directions, can be varied by changing the number of the main threads of Ko.

So, applying the initial basic weave, when Ko = 24, a diagonal weave is obtained with a rapport based on 46 threads, having wider longitudinal sections, as shown in FIG. 3.

A multiple change in the direction of the relief strips on the surface of the fabric is achieved by successive changes in the sign of the vertical shift several times; for this, the diagonal weave obtained previously is used as the basic weave.

So, using as the basic weaves the diagonal weaves depicted in figure 2 and figure 3, when Ko = 36 we get the diagonal weaves shown in figure 4 and figure 5, with an increased number of longitudinal sections having different directions of relief bands up to six and four, respectively.

The number of hems required to produce all these weaves is eight, which is due to the number of differently interwoven warp threads of the base diagonal weave.
