Abstract

FIELD: textile industry. SUBSTANCE: fabric has base warp threads and weft threads and is executed in weft interweave provided by using additional forming warp threads and interweaving weft threads. Interweaving weft thread is initially arranged forward of base weft threads in fabric manufacture course and is further laid in diagonal orientation so that it overlaps base warp threads and weft threads, with further laying under forming warp thread or several forming threads and repeatedly directed in diagonal orientation so that it overlaps base warp and weft threads, with following returning to its initial level and formation of zigzag line. EFFECT: improved physical and mechanical properties and increased consumer qualities. 13 dwg

Description

The invention relates to weaving the textile industry and relates to the improvement of the weaving of threads in fabric. Shilov weave fabric can be used for all types and classes of fabrics.

Currently, there are a large number of interweaving threads in the fabric, which is used in all areas of human activity. A large number of fabrics (more than 50%) are used for technical purposes, where specific properties are required from them: strength, abrasion resistance, uniformity of structure, etc. So, for example, in the manufacture of car tires, woven cord is used. As an element carrying a load, there are the main threads that have leno weaving [1, p.186]. However, due to the low density of the weft (7-9 n / dm), the main threads have the ability to arbitrarily move along the weft. In this case, the formation of sites with different densities on the basis is possible. The position of the threads in the cord during the rubberizing process is not controlled, which ultimately can affect the final quality of the products.

It is known that in fabrics obtained from STB and ATPR machines, the embedded edge is 3-4 times wider than fabrics obtained by shuttle machines and reaches 2 cm, and this is a large loss of raw materials. Although recently leno weaving has been used for edge formation [1, p.186], which allows reducing the edge width, but its quality does not correspond to further technological processes that the fabric passes in the decoration. The edge creeps, gives a large fringe, worsening the quality of the finished product, and, as a result, reducing the cost of fabric.

The technical result of the invention is to improve the physico-mechanical and consumer properties of tissues.

The specified technical result is achieved by the fact that in a fabric with Shilov weaving containing root warp and weft, according to the invention, the fabric has a weft-leno weave (Shilov weave), for the formation of which there are additionally forming warp and weft weft. Moreover, the leno weft thread is located first in front of the root weft threads along the fabric production, after which the leno weft thread is placed diagonally with the overlapping of the main and weft threads, then under the forming main thread and again diagonally with the overlapping of the main and weft threads, returning to its initial level with the formation of a zigzag.

The weft leno rigidly fixes the warp threads and prevents them from moving along the weft. Using weft-leno weaving with other complex weaves (pile, loop, etc.), we can obtain fabrics with new external effects, improving their consumer properties.

Figure 1 presents a view of fabric with weft-leno weave. The fabric has a basic plain weave and contains warp yarns 1 forming the warp yarns 2, root weft yarns 3 *, 3 ** and leno weft yarns 4. Figures 2 through 7 show a sequence diagram of the formation of weft leno weaving, where FIG. 2 - the initial position, FIG. 3 - the initial phase of loop formation, FIG. 4 - the middle phase of loop formation, FIG. 5 - the final phase of loop formation, FIG. 6 - the laying of the leno weft thread, FIG. 7 - the final phase of the loop formation leno weave. Positions 1, 2, 3 *, 3 ** and 4 in FIG. from 2 to 7 correspond to the designation in figure 1, 5 - reed, 6 - hook special design. In FIG. From 8 to 13 a photo of various fabrics with weft-leno weaving is presented. In Fig. 8 (face) and Fig. 9 (wrong side) - fabric corresponding to the pattern shown in Fig. 1, Fig. 10 (face) and Fig. 11 (wrong side) - fabric in which the weft is formed by two forming warp threads and intercepts three root weft threads, Fig. 12 (face) and Fig. 13 (wrong side) is the fabric where the weft-leno weave is formed by three forming warp threads and intercepts four root weft threads.

Obtaining weft-leno weave (Shilov weave) for weaving, depicted in figure 1, is carried out for three turns of the main shaft of the loom on traditional equipment with two weaving Navoi (as receiving leno from the main threads).

Figure 2 presents the initial position, conventionally taken as the beginning of the first revolution of the main shaft of the loom. Birdo 5 is in the back position (standing phase), at this time, the root and forming the main threads due to galev remises (not shown) form a pharynx in the traditional way. At the same time, the hook 6 captures the forming main thread 2. The number of hooks depends on the number of forming warp threads and is located across the width of the fabric. A 3 * root weft thread is laid in the pharynx. After laying the weft, Fig. 3, the pharynx is closed by the root and forming ones that are not currently taking part in the formation of the weft-leno weave by the warp threads and the surf of the root weft thread to the edge of the fabric. At the same time, compensators (not shown) release the tension of the forming main threads (the threads are loosened to the required length). The forming main thread 2 hook 6 is fed forward (towards the chest). This is necessary so that the hook 6 does not interfere with the surf and in the future, due to its special design, could form a loop from it.

The second revolution of the main shaft of the loom. After the surf, the reed 5 retreats to its rear position. A pharynx is formed from the main threads, a view of this pharynx is shown in Fig. 4. A second root weft thread 3 ** is laid in the ABC triangle, formed on one side by a bird, on the other sides, by the lower branch of the forming base 2 and the upper branch of the root base 1.

There is no relationship in quantity between the warp and forming warp threads and the warp and leno threads of the weft. The pattern of the fabric depends on the requirements for the fabric, or on the creativity of the desinator. Therefore, the main warp threads 1 can be located in the lower branch of the pharynx, as shown in Fig.4.

After laying the second root weft thread, surf occurs, while the forming main thread takes the form of a loop (figure 5). The loop (in the form of a drop or other other form) is obtained due to the fact that on both sides the ends of the thread emerging from the fabric of the elongated forming main thread are located between two root weft threads 3 * and 3 **, and the central part is formed by a hook 6.

The third revolution of the main shaft of the loom. After the surf, the reeds retreat. A pharynx is formed from the root warp threads. At the same time, a loop from the forming basis of thread 2 is inserted into the pharynx by hook 6 (Fig. 6). A weft thread 4 is laid in the formed pharynx and always inside the loop, which will become leno. After laying the leno duck 4, the hook 6 is released from the forming main thread. Birdo begins to surf the leno weft thread. Simultaneously with the movement of the reed 5 to the edge of the fabric, the compensators select from the fabric formation zone the incremental length of the forming thread, which was necessary for the formation of a loop. The forming main thread is pulled between the root weft threads 3 * and 3 **. Compensators should create such a tension forming the main thread, which will allow it to take the same phase of the structure (bending), which have the main warp threads. The formation of a weft-leno weave begins. This is due to dragging the leno weft yarn forward of the root weft yarn.

This happens in those places where the forming main thread acts on the leno weft thread. For its part, the main warp yarns 1 (see FIG. 1), located to the left and right of the forming thread, prevent the leno duck from moving forward, leaving it behind the root weft thread. When the phases of the structure (bending) of the root and forming base are approximately the same, the formation of the weft-leno weave will end (see Fig. 8).

Birdo should not approach the front position before the formation of the weft grafting is completed. In FIG. Figure 7 shows the position of the main threads (at the time of surf), when the formation of a weft-leno weave is completed.
