Description

The invention relates to multi-layered textile technical materials and may, in particular, be used in the manufacture of a trampoline mesh.

The purpose of the invention is to improve performance by increasing tensile strength in the longitudinal and transverse directions, breathability and reducing material intensity.

FIG. 1 shows the structure of the material; FIG. 2 is the same longitudinal section; on fig.Z - the same cross section.

Multi-layered textile material contains filling weft threads 1-4, having different interlacing patterns.

in areas A and B, In section A, threads 1 and 3 form long decks 5 of the front surface of the material, and threads 2 and 4 on the wrong surface.

The skeleton warp yarns 6, bound with the binding yarns 7, form a longitudinal insulated layer A.

In another section B, weft filler yarns 1–4 form a single-layer fabric, interlaced with the basic filler yarns 8–11 with a plain weave. As seen in FIG. 3, sections A and B alternate.

In the structure of the material there are two groups of basic filler threads.

The even filling filaments 9 and 11 in sections C are interlaced with the frame weft threads 12 and form a transversal separation layer (Fig. 2).

The odd filler threads 8 and 10 in these sections C form long decks 13 above and below the frame weft threads.

The main filler yarns 9-11 in other parts of the D fabric (Fig. 1) are interwoven with the filling weft yarns 1-4 and form a single-layer fabric. In the fabric there are alternating in the direction of the base areas C and D of different structure (figure 2).

At the intersections of the longitudinal A and transverse C of the frame layers (Fig. 1), the weft frame weft threads 12 are located above and below the frame longitudinal insulated layers.

The linear density of the frame weft yarns 12 is greater than the linear density of the complementary weft yarns 1-4. The linear density of the skeletal base yarns 6 is also greater than the linear density of the filler main yarns 8-11.

In Fig. 1, it can be seen that the longitudinal insulated frame layer A is woven, since the skeleton main threads 6 are interwoven with the connecting threads 7 according to the law of weave. The longitudinal insulated layer can also be made of woven ribbon, from knit strips, and the skeleton main threads themselves can be made from wire or monofilament.

Thus, the proposed material contains areas where all the threads are interlaced, and hollow sections, in which high-strength frame threads 6 and 12 are earned. Threads 1-4 ducks and threads 8-11 bases. The filament yarns have a lower linear density as compared to the skeleton ones and form tissue with increased airtightness.

Such a material allows to combine the requirements for high strength and airtightness with less material intensity.

Frame and filler warp and weft threads vary in strength, appearance or thickness, density in the material.

The formation of the proposed structure on a loom is carried out as follows.

To produce material is necessary

rapier machine with a duck changer. According to a given program, weft threads are introduced into the throat, either frame or filling. For the main yarn, two are required: filling one

0 main threads, on the other - skeleton main threads, which are made in the form of finished woven tapes or monofilaments. Otherwise, the process of making tissue does not differ from the traditional.

5 The presence of tissue sections consisting only of filler threads interlacing between them significantly reduces the material consumption and the filling of the material, increases the breathability,

0 and also provides fixation of the material. These requirements are imposed on many technical materials, such as fabrics for the manufacture of trampolines, bags for transporting oats, etc. The proposed fabric satisfies such requirements.
