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.

A known method of producing twill weave fabrics in which the direction of the lines of the base twill is changed both along the length of the fabric, by changing the sign of the horizontal shift of the overlap to the opposite after a given number of weft threads, and along the width of the fabric by changing the sign of the vertical shift of the overlap to the opposite after a given number the main threads (see Kutepov OS, Structure and design of fabrics. M: Legprombytizdat, 1988, p. 42).

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 both in width and length 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 both in width and length of the fabric. As a result of this, a diamond-shaped pattern of relief strips running in different directions is obtained on the surface of the fabric. Such diagonal weaves can be called diamond-shaped diagonals.

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 by changing the sign of the vertical shift of the floors to the opposite after a given number of warp threads and along the length of the fabric by changing the sign of the horizontal shift of the floors to the opposite after a given number of weft 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 + 3/2 + 1/2 + 2/1;

- shift value So = 2;

- rapport based on Ro = 8;

- duck rapport Rу = 16.

2. Set the number of warp yarns - Ko = 19 and weft yarns - Ku = 19, after which the sign of the corresponding shift is reversed.

3. The sizes of the rapports of the new diagonal weave are determined:

the rapport on the basis is determined by the number of warp threads, after which the shear direction is changed - Ro = 2 · Ko-2 = 36, and the duck rapport is determined by the number of weft threads, after which the shear direction is changed - Ru = 2 · Ku-2 = 36.

4. The new diagonal weave, shown in figure 2, is built in the following order:

- build the base diagonal;

- continue to build the base diagonal on the main threads up to the nineteenth (Ko) thread, inclusive, and then, starting with the twentieth (Ko + 1) thread, the construction is carried out in the reverse order, that is, the twenty-first thread repeats the eighteenth main thread, the twenty second - seventeenth etc;

- continue to weave the weft yarns, repeating the weft yarns built earlier, starting from the first, until we get nineteen (Ku) yarns, and then, starting from the twentieth (Ku + 1) yarn, the construction is carried out in the reverse order, then there is twenty-first thread repeats the eighteenth weft thread, twenty second - seventeenth and so on;

- check the constructed weave on the basis of equality of the last and second rapport threads.

The sizes of patterns on the surface of the fabric, formed by relief strips directed in different directions, can be varied by changing the number of warp threads — Ko and weft threads — Ku, which may not be equal to each other.

So, using the initial basic weave, when Ko = 19 and Ku = 12, a diagonal weave is obtained with a weft repeat 22 of the yarn having a smaller size of the fabric as shown in FIG. 3.

Since the given number of yarns Ku = 12 is less than the rapport along the weft of the base diagonal, only twelve (Ku) weft yarns are constructed from the previously obtained weave at the third construction stage, and then in the reverse order.

A multiple change in the direction of the relief strips on the surface of the fabric is achieved by successively changing the sign of the corresponding shifts (horizontal and vertical) several times, for this, the diagonal weave that was received earlier is used as the basic weave.

So, using as the basic weaves the diagonal weaves depicted in FIG. 2 and FIG. 3, we obtain at Ko = 30 and Ku = 30, respectively, the diagonal weaves shown in FIG. 4 and FIG. 5 forming on the surface of the fabric more complex rhomboid patterns from relief strips.

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.
