Abstract

FIELD: textile, paper.

SUBSTANCE: in proposed method of combined weave fabrics production, initial weaves are simultaneously matched. At the same time view of resulting overlap is specified by view of its larger number of weaves that participate in matching. In case numbers of weft and warp overlaps are equal, one of the following domination principles is used: weft, warp or even, when each odd overlap is warp, and each even overlap is weft.

EFFECT: expanded assortment of combined weaves fabrics.

Description

The invention relates to the production of textile materials and for the manufacture of fabrics of combined weaves produced on weaving machines with remodel carriages.

The closest method of the same purpose to the claimed invention according to the totality of features is the method of obtaining crepe weave fabrics by combining several weaves (see Kutepov O.S. Structure and design of fabrics. M: Legprombytizdat, 1988, p. 51), adopted as an analogue. In this method, all the original weaves are sequentially built on the crepe weave repeat area. Since the initial weaves are combined sequentially, they always combine two weaves regardless of the number of initial weaves: the first weave and the second weave, the resulting weave and the third weave, the resulting weave and the fourth weave, and so on. The combination of weaves is carried out on the floors. When using the method adopted for the prototype (see O. Druzhinskaya, Development of automated methods for constructing filling patterns of fabrics of combined weaves. // Thesis for the degree of candidate of technical sciences - M .: MGTU named after A.N. Kosygin , 2007, p.52), the combination of the initial weaves is also performed sequentially, but the type of the resulting overlap obtained by combining two overlaps is determined by the applied principle of combining weaves. There are two known principles of combining: "addition" and "subtraction", differing in the form of the resulting overlap when combining two main floors (figure 1). The main overlaps are represented by filled cells, and the weft overlaps are represented by unfilled cells.

The disadvantages of the known method, adopted for the prototype, is that in the known method, the number of source weaves does not actually affect the type of the resulting overlap. So, when using the “addition” principle, combining at least one main overlap with any number of weft overlaps always gives the main overlap, which often makes it impossible to construct the weave in this way. The principle of "subtraction" is more productive, because it allows you to get the resulting weft overlap with an even number of initial main overlaps (figure 2).

The technical result of the claimed invention is to expand the assortment of fabrics by creating new combined weaves, in which the type of overlap in the rapport is determined not only by the type of overlap of the original weave involved in the combination, but also by their number. If the number of main floors is greater than weft overlaps, then the resulting overlap will be the main, otherwise, weft, as shown in Fig. 3. If the initial overlap of different types is equal, three types of the resulting overlap are possible, which we propose to determine by the applicable principle of dominance:

- weft dominance gives weft overlap;

- the main dominance is the main overlap;

- uniform dominance: each odd overlap is the main, and each even overlap is the weft.

The specified technical result in the implementation of the invention is achieved by combining the original weaves, while combining the original weaves is done simultaneously, while the type of the resulting overlap is set by the type of a larger number of overlaps involved in the combination, in case of equal number of corresponding overlaps of different types, use one of the following principles of dominance: weft, or basic, or uniform, in which each odd overlap is the main, and each even new overlap - weft.

The drawings show: in Fig.1 shows the resulting resulting overlap in a known manner with different principles of combination; figure 2 shows the effect of the number of source weaves on the type of the resulting overlap when building in a known manner; figure 3 shows the effect of the number of source weaves on the type of the resulting overlap when building the claimed method; figure 4 presents the combined weave obtained by combining the three original weave: in a known manner (1) and (2), as well as the claimed method (3); figure 5 shows the combined weaves obtained by the known (1) and claimed (2) - (4) methods when combining the four original weaves.

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

1. The initial weaves are specified, which are used as either regular weaves or fragments thereof in any quantity. For example, the three weaves shown in FIG. 4.

2. Rapport is determined based on the warp and weft of the combined weave as the smallest common multiple of the corresponding rapports of the original weaves - the value of the rapport on the warp and weft is 12 threads.

3. The construction of the weave (3) are on the floors, starting from the first weft thread. The appearance of each overlap is determined by the type of the corresponding overlaps of the original weaves: the first overlap is the main one, since in the initial weaves all the first overlaps are basic. The second overlap is weft, since the second overlap is weft for the canvas and twill, and the main one for matting. The third overlap is the main one, since the initial weaves of the three corresponding overlappings have two main overlaps, and so on.

When combining an even number of the original weaves indicated in FIG. 5 in a known manner, construction is possible only using the principle of “subtraction” (1), using the claimed method, three variants of combined weaving can be obtained, shown at positions (2) - (4) and differing in the form of the resulting overlap in case of equality of the corresponding overlappings of different types in the initial weaves. So, when combining the first overlaps of the initial weaves, they have two main and two weft overlaps, therefore, when weaving is constructed (2), weft dominance is used, making the resulting overlap weft. When using the main dominance, this overlap and the like will be the main overlaps - as a result, weave is obtained (3). The interweaving (4) is constructed on the principle of uniform dominance: each odd overlap is the main, and each even overlap is the weft.

Claims (1)

A method of producing fabrics of combined weaves, in which the initial weaves are combined, characterized in that the initial weaves are combined at the same time, while the type of the resulting overlap is set by the form of a larger number of overlaps involved in the combination, in case of equality of the number of corresponding overlaps of different types, use one of the following principles of dominance: weft, or basic, or uniform, in which every odd overlap is basic, and every even overlap rytie - weft.
