Description

 The invention relates to weaving technology and can be used in the manufacture of leno fabrics.

 A known method of producing fabric on a loom, which consists in sifting the main threads in heaps and in the grafting of each of the main threads with several adjacent main threads by raising and lowering the threads and moving them in opposite directions in the plane of the fabric / 1 /.

 In the known method, the connection of weft yarns with warp is carried out only by grafting the warp yarns, as a result of which, due to the small number of bonds of the warp and weft yarns, a fabric with reduced strength and wear resistance is obtained.

 The purpose of the invention is to increase the strength and durability of the fabric.

 To achieve this goal, the connection of each weft thread with the main threads is carried out by weaving. The main threads make their way into two heaps.

 In FIG. 1 presents an example diagram of the formation of tissue according to the proposed method; in FIG. 2 arrangement of the main and weft threads in the fabric; in FIG. 3 fabric structure.

 Clips 1a and 1a 'for the main threads 0-6 and 0'-6' are made in the form of strips 7 and 7 ', on which the galev 8 and 8' with holes 9 and 9 'are rigidly fixed. The main threads 0, 1, 2, 3, 4, 5, 6 and 0 ', 1', 2 ', 3', 4 ', 5', 6 ', respectively, are threaded into the holes 9 and 9'.

The movement of warp threads, for example, in a vertical plane, for the formation of the pharynx is as follows. Assume that for the first revolution of the main shaft of the machine, FIG. 1/1 /, the main threads 0, 1, 2, 3, 4, 5, 6, punched into the holes 9 galev 8, are moved upwards in the vertical plane due to the upward movement of the strap 7 of the heald 1a, and the main threads 0 ', 1' , 2 ', 3', 4 ', 5', 6 ', punched into the holes 9' of galev 8 ', move down due to the downward movement in the vertical plane of the strap 7' of the heald 1a '. In this case, the motion paths of the holes 9 and 9 'should not coincide. In the yarn formed from warp threads 0, 1, 2, 3, 4, 5, 6 and 0 ', 1', 2 ', 3', 4 ', 5', 6 ', the weft is laid with a weft thread 1u, which is then closed nailed to the edge of the fabric. In this case, the path of movement, for example, of the hole 9 with thread 2 will pass between the paths of the holes 9 'with threads 1' and 2 '. The arrangement of the main threads between each other and the weft 1u in the fabric is shown in FIG. 2. A hatched cell with a number indicates that the main threads 0, 1, 2, 3, 4, 5, 6 are on top of the weft thread 1y. Cells with the designation Y _1B show that the weft thread 1y is located on top of the main threads 0 ', 1', 2 ', 3', 4 ', 5', 6 '.

For the second revolution of the main shaft of the machine, FIG. 1 / II /, the strap 7 of the heald 1a moves down. The warp threads 0, 1, 2, 3, 4, 5, 6, threaded into holes 9 of galev 8, form the lower branch of the throat. During this time, the strap 7 'of the heald 1a' moves up, and the warp threads 0 ', 1', 2 ', 3', 4 ', 5', 6 ', threaded into the holes 9' of galev 8 ', form the upper branch of the throat. A second weft thread 2y is laid in the formed pharynx, which is then nailed to the weft thread 1u at the edge of the fabric. The arrangement in the fabric of the main threads between each other and the weft 2y is shown in FIG. 2. Cells with crosses and numbers show that the main threads 0 ', 1', 2 ', 3', 4 ', 5', 6 'are located on top of the weft thread 2y, the cells with the designations Y _2c show that the main threads 0, 1, 2, 3, 4, 5, 6 are located below the weft thread 2y.

For the third revolution of the main shaft of the machine, FIG. 1 / III /, the strap 7 of the heald 1a moves up, and the strap 7 'of the heald 1a' down. In this case, the main threads 0, 1, 2, 3, 4, 5, 6 form the upper branch of the throat, and the warp threads 0 ', 1', 2 ', 3', 4 ', 5', 6 ', respectively, the lower branch of the throat. The upper bar 7 moves to the right according to the figure, the lower one by the same amount to the left so that when closing the pharynx, the path of movement of the hole 9 with thread 2 passes between the paths of the holes 9 'with threads 3' and 2 '. A third weft thread 3u is laid in the formed pharynx, which is nailed at the edge of the fabric to the weft thread 2u. The mutual arrangement in the fabric of the main threads between themselves and the weft thread 3y is shown in FIG. 2. Shaded cells with numbers show that the main threads 0, 1, 2, 3, 4, 5, 6 are located on top of the weft thread 3y, and cells with the designations Y _3c show that the weft thread 3u is on top of the main threads 0 ', 1 ', 2', 3 ', 4', 5 ', 6'. In this case, from the displacement of the warp threads to the right and left, the warp thread 0 is interwoven with the warp thread 0 ', 1 s 1', 2 s 2 ', 3 s 3', 4 s 4 ', 5 s 5', 6 s 6 '. Thus, for the third revolution of the main shaft of the machine when surfacing the weft thread 3y in the edge of the fabric to the weft thread 2y, the main threads are intertwined with each other and with the weft thread 3y. (The interweaving of warp threads among themselves in Fig. 2 is not shown).

 For the fourth revolution of the main shaft of the machine, the lower bar 7 'of the heald 1a', FIG. 1 (IV), moves up, and the upper bar 7 of the heald 1a moves down to form the next throat, in which the fourth weft thread 4u is laid. Then, the weft thread 4y is nailed at the edge of the fabric to the weft thread 3y.

The weaving of warp yarns with weft thread 4y is shown in FIG. 2. Cells with a cross and numbers correspond to the fact that the main threads 0 ', 1', 2 ', 3', 4 ', 5', 6 'are located on top of the weft thread 4u, and the cells with the designations Y _4c show that the weft thread 4y is located on top of the main threads 0, 1, 2, 3, 4, 5, 6.

During the fifth revolution of the main shaft of the machine, the upper plate of the healder 1a moves up and to the right in the figure, and the lower plate of the healder 1a 'moves down and to the right so that the path of movement, for example, of the hole 9 with the main thread 2 passes between FIG. 1 (VI), the trajectories of the holes 9 'with warp threads 3' and 4 '. A weft thread 5u is laid in the formed pharynx. After surfing the weft thread 5y at the edge of the fabric to the weft thread 4u, it is interwoven with warp threads. In turn, the warp threads are intertwined. So the main thread 0 is intertwined with the warp thread 1 ', 1 s 2', 2 s 3 ', 3 s 4', 4 s 5 ', 5 s 6'. The location of the weft yarn 5u in the fabric relative to the warp and warp yarns is shown in FIG. 2. Cells shaded with numbers correspond to the fact that the warp threads 0, 1, 2, 3, 4, 5 in the fabric are on top of the weft thread 5y. Cells with the designations Y _5y indicate that the weft thread 5y is located in the fabric on top of the remaining main threads.

For the sixth revolution of the main shaft of the machine, the strap 7 of the heald 1a of FIG. 1 (VI) moves through the galev 8 holes with warp threads 0, 1, 2, 3, 4, 5, 6 down, and the strap 7 'heald 1a' through galev 8 'holes 9' with warp threads 0 ', 1', 2 ', 3', 4 ', 5', 6 'respectively up. A weft thread 6u is laid in the formed pharynx, which is then nailed at the edge of the fabric to a weft thread 5u. The location of the weft yarn 6y in the fabric relative to the warp yarn is shown in FIG. 2. Cells with crosses correspond to the fact that the main threads 1 ', 2', 3 ', 4', 5 ', 6' are located on top of the weft thread 6u, and the cells with the designations Y _6c show that the remaining warp threads are located below the weft 6u .

During the seventh revolution of the main shaft of the machine, the strap 7 of the heald 1a, FIG. 1 (VII), moves up and to the left according to the figure, and the strap 7 'heald 1a' moves down and to the right. The amount of movement of the strap 7 of the heald 1a to the left, and the strap 7 'of the hedge 1a' to the right should be such that the path of movement, for example, holes 9 with the main thread 2 when closing the pharynx passed between the paths of the holes 9 'with warp threads 2' and 3 ' headers 1a '. A weft thread 7u is laid in the throat formed from warp threads, which is then nailed at the edge of the fabric to the weft thread 6u. In this case, the warp threads are intertwined with each other and the weft thread 7u. So, warp thread 0 is intertwined with 1 ', 1 s 2', 2 s 3 ', 3 s 4', 4 s 5 ', 5 s 6'. The location of the weft yarn in the fabric relative to the warp and warp yarns is shown in FIG. 2. Shaded cells show that the main threads 0, 1, 2, 3, 4, 5, 6 are located on top of the weft thread 7y. Cells with the designations Y _7c show that the weft thread 7y is located on top of the remaining main threads under consideration.

During the eighth revolution of the main shaft of the machine, the strap 7 'of the heald 1a', FIG. 1 (VIII), moves up, and the strap 7 of the heald 1a moves down the figure. In the formed pharynx, another weft thread 8u is laid, which is nailed at the edge of the fabric to the weft thread 7u. The location of the weft yarn 8y with warp yarns is shown in FIG. 2. Cells with crosses and numbers show that the main threads 0 ', 1', 2 ', 3', 4 ', 5', 6 'are on top of the weft thread 8y, and the cells with the designations Y _8c show that the weft thread 8y located on top of the remaining main threads.

 During the ninth revolution of the main shaft of the machine, the upper bar 7 of the heald 1a moves up and to the left, and the lower bar 7 'of the hedge 1a' moves respectively down and to the right. The magnitude of the movement of the strap 7 and strap 7 'should be such that the path of movement, for example, of the hole 9 with the base 2 of the heald 1a when closing the pharynx was between the paths of the holes 9' with the warp threads 1 'and 2' of the heald 1a '. Such an arrangement of heaps 1a 1a ′ is shown in FIG. eleven/. A weft thread 9y is laid in the throat formed from warp threads, which is then nailed to the edge of the fabric to the weft thread 8y. In the process of surfing, the main threads are intertwined with each other and a weft thread 9y. In this case, the main thread 0 is intertwined with the main thread 0 ', 1 s 1', 2 s 2 ', 3 s 3', 4 s 4 ', 5 s 5' and 6 s 6 '. The arrangement of the main threads between each other and the weft thread 9u in the fabric is shown in FIG. 2.

 Galeva remise 8 and 8 'are rigidly fixed respectively on the strap 7 of the remise 1a and the strap 7' of the remise 1a 'strictly at a distance equal to Δl Halev from the galev.

 Moving the strips 7 of the remix 1a to the right, and the strips 7 'of the remix 1a to the left or the strips 7 of the remix 1a to the left, and the strips 7' of the remix 1a 'to the right in the horizontal plane can be carried out only at such a moment when the remiz 1a moves up, and Header 1a 'moves down. The holes 9 with warp threads 0, 1, 2, 3, 4, 5, 6 will be above the holes 9 'with warp threads 0', 1 ', 2', 3 ', 4', 5 ', 6'. Thus, healds 1a and 1a 'can be moved in a horizontal plane through each revolution of the main shaft of the machine, when heald 1a moves up, and the lower 1a' - down. The total amount of movement of the remises 1a and 1a 'in the horizontal plane should be equal to Δl. Therefore, when opening the next pharynx in every second revolution of the main shaft of the machine, the heald 1a and hedge 1a 'must move in the horizontal plane by Δl / 2. Moreover, if the heel 1a according to the weave pattern moves to the left in the horizontal plane, then the heel 1a 'moves to the right, and vice versa.

 The movement of the remises 1a and 1a 'in the horizontal plane can be carried out according to a special program, and the movement of these remises in the vertical plane for the formation of a pharynx from the warp threads can be carried out using the existing cam shedding mechanism.

 Increasing the strength of the fabric obtained by the proposed method occurs due to the interweaving of warp threads between each other and with weft threads.

 In the conventional method of forming plain weave fabric using two heaps, the rapport on the basis is equal to the rapport on the weft and equal to two. Therefore, if two adjacent yarns of different colors were used in the basis, then a colored strip will pass along the fabric.

When forming the fabric according to the method we proposed using two remises, in our case, the duck rapport R _y is
R _y = R $\genfrac{}{}{0ex}{}{\text{′}}{\text{y}}$ • R _n.o
Where
R $\genfrac{}{}{0ex}{}{\text{′}}{\text{y}}$ - weft repeat weft with the usual method;
R _n.o. repeat pattern of interweaving of two adjacent warp yarns within the repeat pattern of interweaving R _y .

In our case, R $\genfrac{}{}{0ex}{}{\text{′}}{\text{<figure-callout id="2" label="y" filenames="00000002.png" state="{{state}}">y</figure-callout>}}$ 2, R _n.a. 4, R _at 8.

In turn, the rapport is equal to
R _o = R $\genfrac{}{}{0ex}{}{\text{′}}{\text{o}}$ • m,
Where
R $\genfrac{}{}{0ex}{}{\text{′}}{\text{o}}$ - rapport weave on the basis of the conventional method;
m is the number of warp threads interwoven with each other.

In our case, R $\genfrac{}{}{0ex}{}{\text{′}}{\text{<figure-callout id="2" label="o" filenames="00000002.png" state="{{state}}">o</figure-callout>}}$ 2, m 2, R _about 4.

According to our proposed method for producing fabric in the case of using two adjacent main yarns of different colors as the basis, FIG. 2, warp threads 2 and 2 ', colored patterns will be located along the fabric with a width of R _о 4 and a length equal to R _at 8. The width and length of the pattern in the fabric can be changed due to the order of changing the weaving of the warp threads together and the repetition of weaving in the fabric when the usual way of forming tissue.
