Mesh fabric under polymer coating

 

Fabric refers to the textile industry and can be used as a reinforcing traction frame technical products with elastomeric coating. Mesh fabric under the polymer coating contains a synthetic core and weft threads made rubinowy weave with a fixed twill 2/1 main pastrami. Rapport on the basis contains an even number of yarns, at least 6 at intervals of 4, forming two identical threads of pauropoda - front and back with an odd number of threads, at least 3, and within each pauropoda front warp threads are interwoven with the weft threads by the following mathematical relationships: 0,5 Ry/l+2/l(0,5 Ry-l)/3, where Ry- rapport weave on a duck. The corresponding warp threads front and back of paulapatton intertwined in antiphase to each other, forming on a duck reverse “mirror” symmetry axis relative to the longitudinal axis. Each pauropoda on the basis of there are two groups alternating one equally interwoven warp threads, shifted relative to each other along the base on the number of threads equal to half of rapport on a duck, and the number of equally intertwined rapport weave in the warp. Each weft rapport along a warp contains 2 full plain rapport, (0,5 Ry-1) the same paulapatton filling reps 0,5 Ry/0,5 Ryand (0,5 Ry-3) linen paulapatton located between rapsovye polyrepertory. Relationship linear density of warp and weft threads are in the range of 1.8 to 4.1. The fabric is highly durable. 1 C.p. f-crystals, 12 tab., table 2.

The invention relates to the textile industry and can be used as a reinforcing traction frame technical products with a polymer coating, mainly mnogoproletnyh conveyor belts for transportation of rocks, flat belts and chassis trucks (caterpillars) snowmobiles.

The basic technical requirements to the tissues beneath the polymer coating is used as a reinforcing traction frame mnogoproletnyh conveyor belts, flat belts and caterpillars snowmobiles are: high breaking load (from 65 to 300 kgf/cm) on the basis of the minimum (not more than 4.5%) deformation elongation in the range of operating loads (10% of the breaking), and vitiagivaet tape should not exceed rim material, exclusive bundle of strips of reinforcing frame.

Known fabric TC-200-2, used as a reinforcing traction frame mnogoproletnyh rubber conveyor belts, flat belts and caterpillars snowmobile “Buran”, “Lynx”, “Taiga”. Fabric TC-200-2 is formed by a plain weave woven synthetic yarns, the filling on the basis of equal 93.7-97.4%, the padding duck 34.9-38.59, the ratio of the linear density of warp and weft threads is equal to 0.95-1.0, the ratio of technological densities in the warp and weft is 2.43-2.79, robotka warp equal to 16.6-19.4%, the elongation of the fabric in a range of working loads (10% of the breaking load) 6.0±1.0 and technological shrinkage in the warp in a hot air equal to 9.0±2.0%. The adhesion of the fabric to the rubber is 4.0-4.2 kgf/cm [“polyamide Fabric for conveyor belts and flat belts” GOST 18215-87].

The disadvantage of this woven strip conveyor belts are significant deformation elongation zone workloads (5.0-7.0%) due to high orebody warp (16.6-19.4%), which leads to vitiagivaet technical products by an amount greater than the stroke of the tensioning devices. In addition, nedostatochnaya conveyor belts, flat belts and tracks of snowmobiles on it.

Also known fabric used as a traction frame mnogoproletnyh conveyor belts, flat belts and tracks of snowmobiles made polutorapolnymi weave synthetic filaments formed by the connection of two 4-thread front and back satin weaves by alternating front and back of the main beams, United by a common weft [the Federal Republic of Germany Patent No. 2436922 on CL 29 D 29/00, D 03 D 1/00, 65 G 15/30, publ. 03.03.1977,].

This fabric is mainly suitable for its intended purpose according to the main indicators, however, has a significant drawback - the distance between the threads in process due to the lack of secure long beams and low coupling coefficient equal to 1.01.

In addition, the known tissue surface weave with a fixed key or weft long decks, overlapping consecutive several, not less than 4, filaments opposite system to form on one (front) side convex scars with longitudinal or transverse direction, and on the other (wrong) side of the main or filling decks, sakralen arepretty) according to the law plain (1/1) or twill (2/1 or 1/2) weave. Each repeat of the weave consists of two scars located on the one face side of the fabric, number of threads in which multiple rapport establishing the weave. The basic rules for constructing tissue surface weave shown in table 1 [see the book Kutepov O. S. “the Structure and design of fabrics”, - M.: Legprombytizdat, 1988. P.74-76].

However, the heterogeneity of the adhesion of the front and the reverse sides of the surface are known tissue surface to weave elastomeric coating, due to one-sided location of scars on the surface of these fabrics, i.e., different in appearance and texture of the support surfaces, making them unusable as a reinforcing woven frame under plastic covering.

The most similar in structure and effect is achieved is cellular tissue factor density 0.24-1.0, made of plain or twill 1/2, or matting 2/2, or matting 4/4, or translucent synthetic weave of warp and weft threads with the formation of cells with a size of 0.01-3.5 mm [RF Patent for the invention №2085636, D 03 D 15/00, 1/00, publ. 27.08.1999,, 27.07.1997].

This mesh fabric cannot be used as a reinforcing t is chiroki rock mass, flat belts and chassis trucks (caterpillars) snowmobiles, because it has a breaking load of not more than 60 kgf/cm when the desired amount of from 65 to 300 kgf/see

An object of the invention is the creation of high-strength fabric under polymer coating for reinforcing traction rubber frame mnogoproletnyh conveyor belts, flat belts and caterpillars snowmobile having a high breaking load (from 65 to 300 kgf/cm) on the basis of the minimum (not more than 4.5%) deformation by elongation in the range of operating loads, sufficient (not less than 5.0 kgf/cm) bonding strength to the surface of the fabric with an elastomeric material.

This problem is solved by the fact that the cellular tissue beneath the polymer coating with a coefficient of compaction from 0.24 to 1.0 contains a comprehensive synthetic basic and weft threads, mutually arranged with the formation of cells made rubinowy weave with a fixed twill 2/1 main pastrami. Rapport on the basis contains an even number of yarns, at least 6 at intervals of 4, forming two identical threads of pauropoda - front and back with an odd number of threads, not less than 3. Within each pauropoda face warp ub>-1)/3,

where Ry- rapport weave on a duck, equal to from 8 to 20 with an interval of 6. The corresponding warp threads front and back of paulapatton intertwined in antiphase to each other, forming on a duck reverse "mirror" symmetry axis relative to the longitudinal axis. Each pauropoda on the basis of there are two groups alternating one equally interwoven warp threads, shifted relative to each other along the base on the number of threads equal to half of rapport on a duck, and the number of equally interwoven warp threads in each group of pauropoda respectively is:

0,25 Ro+0.5 and 0.25 Ro-0,5,

where Ro- rapport weave in the warp.

Each weft rapport along a warp contains 2 full plain rapport, (0,5 Ry-l) same paulapatton filling reps 0,5 Ry/0,5 Ryand (0,5 Ry-3) linen paulapatton located between rapsovye polyrepertory.

Alternating front and back main polarity cellular tissue are separated from each other with a gap of 1 to 5 mm

The ratio of the linear density of warp and weft should be within 1.8-4.1.

These distinctive features, the p>The inventive arrangement of the warp and weft threads in the repeat of the weave allows the fabric, having a minimum (not more than 4.0%) deformation by elongation in the range of operating loads (10% of the breaking), sufficient (not less than 4.5 kg/cm) bonding strength to the surface of the fabric with an elastomeric material, a high coefficient of coupling fabric with an elastomeric material, a high coefficient of coupling threads (not less than 5.0).

To improve the bond strength between the surface of the proposed fabric with elastomer - rubber between each paulapatton on the basis of the installed gap equal to from 1 to 5 mm

In Fig.1-12 shows the possible variations of the motif weave offer fabrics with repeats on the basis of from 6 to 18 threads at intervals of 4 and rapport on a duck from 8 to 20 threads at intervals of 6.

In Fig.1-4 above figures weave offer fabrics with design patterns in the warp and weft, is equal to: 68; 108; 148; 188.

In Fig.5-8 above figures weave offer fabrics with design patterns in the warp and weft, is equal to: 614; 1014; 1414; 1814.20; 1020; 1420; 1820.

The offered fabric is made from synthetic (polyester or polyamide) yarn on the Shuttle, microcentric or rapier weaving machines equipped samoobrazovanie carriage 4 or more shafts with repeats on a duck from 8 to 20. When filling fabric on looms in each tooth Byrd sneaks half of rapport (3, 5, 7 or 9 threads on the base).

The fabric is formed with gaps between polyrepertory. For this PROPARCO in the reeds produce polarpro in the tooth Byrd, skipping from one to 3 teeth, forming gaps between the front and back rubikovej polyrepertory.

To confirm the technical result of the invention were produced experimental tissue of the proposed design. Main technical characteristics of the tissue analogues and tissues of the proposed structures are shown in table 2.
