Fencing fabric

 

Fabric refers to the textile industry and can be used for the manufacture of special products, mainly for apparel, sports jackets for fencing electrofoils and Electrocable. Fencing fabric made melkozubchatymi weave and contains two systems of main and weft threads, each of which includes strands of fibers, forming the background, and a tinsel strands forming the conductive grid. Rapport tissue on the basis contains 8-10 threads, including 2 chromium-plated, with tinsel main threads are in pairs, each of which is within rapport interwoven with the weft threads by the following mathematical relationships:

(0,5 Ry+1)/0,5(Ry-1)

with a shift relative to each other, equal to 0.5 Rywhere Ry- rapport fabric on a duck. Rapport tissue duck contains from 4 to 8 threads, including single glitz 1 or 2, located every 2 or 3 background the weft yarn so that within the entire repeat of the weave each tinsel weft thread overlaps one of the two chromium-plated main thread and overlaps the second glitz main thread. The fabric has a low bending stiffness when registering>sabreena relates to the textile industry and can be used for the manufacture of special products, mainly for apparel, sports jackets for fencing electrofoils and Electrocable.

Fabrics for apparel, sports jackets for fencing electrofoils and Electrocable must have the following operational characteristics: sufficient surface conductivity (not more than 5.0 Ohms) at the optimum content of the conductive tinsel threads (not more than 30%), the minimum surface density (200±10 g/m2and low bending stiffness (not more than 4 g/cm).

Famous cloth “Armor” used for protective clothing fencers. The fabric is compacted to 120-170% filling made melkozubchatymi weave with destinationin repeats in the basis and duck. At the same time within the rapport each thread of the warp and weft has one long trinitatem overlapping and three short single overlap. Each using a three-rail overlapping continue - three short and Vice versa, after three short single-strand slab should be one long using a three-rail overlap, each time forming a sequence of overlapping, equal to 3/1+1/1 or 1/3+1/roodney grid makes it unsuitable for apparel, sports jackets for fencing electrofoils and Electrocable.

Closest to the technical essence and the achieved result is fencing fabric made melkozubchatymi weave with repeats 18/6 and contains two major system and weft threads, each of which includes a chemical (rayon) yarn linear density of 18.5 Tex x 2, forming a background fabric (60%), and chromium-plated yarns with a linear density of 45.4 Tex, forming a conductive grid (40%). The density of the fabric in the warp is in the range of 25.8-26.8 km n/cm, duck 26,7 was 28.3 n/a see Every 18-thread rapport tissue on the basis contains 10 tinsel strands, glitz and weft threads are arranged in pairs, each of which is repeated every 5 repeats on a duck, forming a conductive cell diagonal to 7.32 mm and an area of 5.53 mm2. The surface density of the fabric is equal to 231±12 g/m2[USSR author's certificate No. 1656020 in class. D 03 D 15/00, 15/02, 1/00, And 63 In 69/02. Publ. 15.06.91, bull. No. 22].

The main disadvantages of this fencing fabrics are a high percentage of metallic tinsel threads (40%) and the resulting high tissue stiffness in bending (up to 4.5 g/cm) and high surface density (231±12 g/m2).

Technical result achieved in the present invention, is achieved by the proposed fencing fabric made melkozubchatymi weave and contains two systems of main and weft threads, each of which includes strands of fibers, forming the background, and a tinsel strands forming the conductive grid.

Rapport tissue on the basis contains from 8 to 10 threads, including 2 tinsel thread, and rapport on a duck contains from 4 to 8 threads, including 1 or 2 tinsel strands, spaced every 2 or 3 background the weft yarn.

Glitz main threads are in pairs, each of which is within rapport interwoven with the weft threads by the following mathematical relationships:

(0,5 Ry+1)/0,5(Ry-1),

with a shift relative to each other, equal to 0.5 Rywhere Ry- rapport fabric on a duck.

Within the entire repeat of the weave every single glitz weft thread overlaps one of the two main tinsel threads and overlaps the second main tinsel thread. Equity investment tinsel thread is 20-30% of the surface density equal to 200±10 g/m2. The main glitz and weft threads is formed on the front surface of the fabric conductive cell area of 4.3-5.2 mm2and the size of the diagonal of 4.3-5,2 mm

The surface is ur fabric allows you to get the fencing fabric, with significantly lower bending stiffness (not more than 4.0 g/cm) and a minimum surface density (200±10 g/m2), while maintaining sufficient surface conductivity (not more than 5.0 Ohms).

The offered fabric is made from helices the Ah type STB, equipped with a two-tone feeder duck.

To confirm the technical result of the invention were produced experimental tissue of the proposed design. The main characteristics of fabrics made in comparison with the characteristics of the fencing fabric of the prototype are shown in table 1. The data in table 1 show that the inventive tissue compared to tissue-a prototype for the equality of the surface electric resistance of not higher than 5.0 Ohms, has the following advantages in terms of operational properties: smaller surface density (210±10 g/m2against 231±12 g/m2the fabric of the prototype), a low content of conductive tinsel threads (not more than 30% against 40% in tissue-prototype) and low bending stiffness (not more than 4.0 g/cm at 4.5 g/cm in the prototype).

Sports jacket, made of a patented fabric, lighter, softer and more comfortable than the jacket of the fabric of the prototype.
