Description

The utility model relates to the production of textile materials and can be used as a reinforcing layer of polymer coating - tent material for cars, light buildings, shelters.

Known fabric - the basis for coatings, formed by weaving (weaving) polyester textured warp and weft yarns 9.2 ... 38.2 tex, surface density 79 ... 225 g / m [1].

However, this fabric cannot be used as the basis for the production of lightweight awnings and shelters due to the high material consumption, stiffness, low tensile strength of tents and shelters.

A harsh polyester fabric used as the basis for polymer coatings containing the main and weft plain weave threads made from textured yarns 25 tex (warp) and 9.2 tex (weft) with a surface density of 78 g / m ² [2] .

- The disadvantage of this basis is the unevenness of the breaking loads on the base and weft - 800 and 100 N / 5 cm (the ratio is 8.0), which unsatisfactorily affects the quality characteristics of the base.

The technical result of the claimed utility model is to improve the technical characteristics of the fabric and its products due to the alignment of the breaking loads on the base and weft to 530 ... 470 and 380 ... 410 N (ratio 1.18 ... 1.36), respectively.

The specified technical result is achieved by the fact that in the woven basis for coatings formed by plain weaving of the main and weft polyester textured yarns, according to the utility model, pneumatically connected threads are used as the main and weft threads, the main threads have a linear density of 18.5 ... 16, 7 tex in the amount of 220 ... 248 threads per 10 cm, and the weft threads are made with a linear density of 18.5 ... 24.5 in the amount of 170 ... 120 threads per 10 cm, while the surface density of the fabric is 70 .. .77 g / m ^2, and the ratio of discontinuous loads Ba s codend - 1.18 ... 1.36.

The large material consumption of 78 ... 225 g / M, and therefore the rigidity of the polymer coating (awnings, etc.) and the low tear strength of the fabric and its products are eliminated in the claimed utility model through the use of the main and weft threads pneumatically connected, moreover, to achieve equal tensile strength, the product of the linear density of the filaments by their number is selected equal both on the basis and on the weft, and the tear strength is achieved by increasing the linear density of the weft yarns.

The table shows the physical and mechanical properties of both the inventive woven warp and similar woven warp.
