Abstract

FIELD: textile, cotton.

SUBSTANCE: this method refers to the production of the two-layer fabrics produced at the looms. The method of production of the two-layer fabric with the design created by the colour of the shot wires provides the formation of the third colour effect, i.e. the mixed colour caused by the location of the wires of different colours on the fabric surface. The mixed colour is achieved by the transfer only of the part of the shot wires of the same colour layer by layer, and the rest of the shot wires of this colour remain in the first layers.

EFFECT: expansion of the range of the fabrics of this construction.

Description

The invention relates to the production of textile materials and for the manufacture of two-layer fabrics produced on looms.

The closest method of the same purpose to the claimed invention according to the totality of features is a method for producing two-layer fabrics with the passage of weft yarns from layer to layer (see Kutepov O.S. Structure and design of fabrics. M .: Legprombytizdat, 1988, p. 127), in which all the weft threads of one color, participating in the formation of the fabric, pass from one layer to another layer along the contour of the pattern at the same time, changing places with all the weft threads of a different color.

This method is adopted as a prototype.

For reasons that impede the achievement of the following technical result when using the known method adopted for the prototype, is that in the known method in the fabric pattern receive only two pure colors, due to the color used weft yarn.

The essence of the invention is to expand the assortment capabilities of two-layer fabrics due to the fact that part of the weft threads of one color passes from one layer to another layer, and the remaining threads of this color remain in the formed layer. Threads of a different color work similarly, with which threads of the first color change places.

The technical result of the proposed method for producing two-layer fabrics is to expand the assortment of fabrics of this structure by obtaining in the pattern created by the color of the weft threads, the third color effect is a mixed color, due to the location on the surface of the fabric next to the thread of different colors.

The specified technical result in the implementation of the invention is achieved by the fact that in the known method for producing two-layer fabrics, all the weft threads of one color pass from layer to layer along the contour of the pattern at the same time, changing places with all the weft threads of a different color.

The peculiarity lies in the fact that only a part of the weft threads of one color passes from layer to layer, changing places with the same number of weft threads of a different color, and the rest of the weft threads of the corresponding color remain in the original layers.

The drawings show: in Fig. 1 shows the interweaving of a two-layer fabric obtained in a known manner: (1) - interweaving of the front surface of the fabric formed in the first section by a white weft, and in the second section by a red weft; (2) —weave pattern of two-layer fabric for each section; (3) - transverse section of the fabric. Figure 2 presents the weaving of two-layer fabric obtained by the claimed method.

Information confirming the possibility of carrying out the invention to obtain the above technical result is disclosed by the example of constructing the weave of a two-layer fabric of the claimed method (figure 2).

The construction is carried out in the following order:

The initial weave is set, which is used as weaves with a weft effect, since the weft threads are a pattern-forming system. For example, four-edged satin.

Two base systems are involved in the formation of the fabric: the upper (indicated by Arabic numerals) and the lower (indicated by Roman numerals) and two weft systems, which vary in color: white ducks and red ducks.

In the first section (1), white ducks, interwoven with the upper base, forms the upper layer of fabric, and red ducks, interwoven with the lower base, forms the lower layer of fabric.

These layers are produced independently of each other. The layers join at the boundary of the sections due to the transition of the weft threads to another layer. So, even threads of a white duck change with the corresponding threads of a red duck. In the second section (4), even white weft threads are interwoven with the lower base to form the lower fabric layer, and even red weft threads are intertwined with the upper fabric, forming the upper fabric layer.

The odd threads of both white and red weft in the second section remain in their layers, intertwining, respectively, with the upper and lower warp (3). This ensures that a mixed color is obtained in the second section, due to the location on the fabric surface of a series of white and red threads (1).

To achieve the specified technical result, alternation of weft yarns is used in fabric repeat in the second section - 2: 2, and in the first section - 1: 1, as shown in figure 2 - weaving of two-layer fabric (2).

Claims (1)

A method of producing two-layer fabrics in which all the weft threads of one color pass from layer to layer along the contour of the pattern at the same time, changing places with all the weft threads of a different color, characterized in that only a part of the weft threads of one color passes from layer to layer, changing places with the same number of weft threads of a different color, and the remaining weft threads of the corresponding color remain in the original layers.
