Method for manufacturing of electrolysis bag and electrolysis bag / 2369667
Invention is related to method for manufacturing of electrolysis bag, inside of which an electrode may be placed. Electrolysis bag is made by method of cloth formation with hollow core at single loom. Bag has hollow section with two separate layers of cloth. Further, at bag edges, layers of cloth are fixed together with the help of weaving sections. Bags are cut from cloth after formation. Open upper part provides for the possibility of electrode insertion inside bag.

Double-layer shaping mesh with high resistance in central plane / 2354764
Double-layer shaping meshes are woven according to general repeating weaving pattern that requires at least 8 sheds in loom. Transverse binding pairs of threads follow single combined line of motion, being woven with layer on paper side and layer on machine side with long internal displacement, at least, under four threads of layer on paper side between points of overlapping and interweaving in layer on machine side. Elements of pairs of threads are displaced to the side relative to each other along single combined line of motion. Mesh has complete filling of base after heat shrinkage by at least 100% of layer drainage area on paper side and layer on machine side - between 25% and 50%, and area of central plane drainage between 8% and 20%.

Multilayer moulding fabric with packed fibres / 2347018
Invention relates to moulding fabric for the moulding part of the paper-making machine. Fabric has an upper layer of weft threads and a lower layer of weft threads, passing in a direction perpendicular to the direction of the movement of the fabric in the machine. Upper (moulding) layer and lower (side of wear and tear) layer are joined forming a multilayered fabric. Compacting threads, passing in a direction perpendicular to the direction of movement of fabric in the machine, set between adjacent weft threads on the side of wear and tear. Compacting threads reduce the volume of emptiness on the side of wear and tear of the fabric without a considerable disruption to the air permeability and increasing the thickness of the fabric. This arrangement of compacting threads also leads to the increase in transverse strength and seam strength and reduces transverse movement of weft threads on the side of wear and tear.

Two-layer fabric production method / 2374366
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.

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

The closest way to the same destination to the claimed invention by a combination of traits is a method of obtaining a two-layer fabrics with the transition of the weft threads of the layer in the layer (see Kutepov O.S Structure and design of fabrics. M: Legprombytizdat, 1988, s), in which the weft threads of the same color involved in the formation of the fabric, pass from one layer to another layer on the circuit pattern at the same time, changing places with all the weft threads of a different color.

This method is adopted for the prototype.

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

The invention consists in expanding the assortment features a two-layer tissue due to the fact that part of the weft threads of one color is transferred from one layer to another layer, and other threads of this color remain in the formed layer. Similarly, there are threads of a different color, with which the threads of the first color are swapped.

The technical result of the claimed SPO is both obtain a two-layer tissue is expanding range of fabrics of this structure by obtaining the pattern, the generated color weft threads, the third color effect - mixed color due to the location on the surface of the fabric adjacent threads of different colors.

This technical result in the implementation of the invention is achieved in that in the known method of obtaining a two-layer fabrics are weft threads of one color is transferred 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 part of the weft threads of one color is transferred from layer to layer, changing places with the same number of weft threads of different colors, and the remaining weft threads of the respective color remain in the original layers.

The drawings show: 1 shows the intertwining of the two-layer fabric obtained in a known manner: (1) to weave the front surface of the fabric formed on the first segment white weft, and the second part of the red weft; (2) the pattern of the weave of a double layer of fabric for each site; (3) - cross section of tissue. Figure 2 presents the double-layer weave fabric obtained the claimed method.

Information confirming the ability of the invention to provide the above technical result is disclosed for constructing double-layer weave fabric savlon the m method (figure 2).

The building is produced in the following order:

Define the initial entanglement, which are used as weave with weft effect, since the pattern forming system are weft threads. For example, chetyrehyarusny satin.

In the formation of tissue involves two system basics: top (indicated by Arabic numerals) and the bottom (indicated by Roman numerals) and two systems duck, distinguished by color: white ducks and red ducks.

On the first segment (1) white ducks, together with the upper base, forms the top layer of fabric, and red ducks, interwoven with the bottom base, the bottom layer of fabric.

These layers develop independently from each other. Bonding occurs on the boundary by moving the weft yarns in the other layer. So, even strands of white duck vary with the corresponding threads of the red duck. The second part of (4) even strands of white weft interweaves with the bottom, form the bottom layer of fabric, and even strands of red weft are interwoven with the upper base forming the top layer of fabric.

Odd thread as white, and red duck on the second site remain in their layers, interacting, respectively, with the upper and with the lower base (3). It provides on the second site, mixed color, due to the location on the surface of the fabric adjacent threads Bel is go and red (1).

To achieve the technical result used alternating weft threads in rapport tissue at the second site 2:2 and on the first section - 1:1, as shown in figure 2 - double-layer weave fabric (2).

A method of obtaining a two-layer tissue, in which all the weft yarn of the same color are transferred 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, wherein only a part of the weft threads of one color is transferred from layer to layer, changing places with the same number of weft threads of different colors, and the remaining weft threads of the respective color remain in the original layers.
