The invention relates to the production of multi-layer covering awning polymeric materials and can be used in the manufacture of tent materials and other reinforced materials used in the construction of prefabricated structures and shelters automotive transport operated in different climatic zones, including in the Far North.

Known awning materials based on polyester fabrics with double-sided imposition of polyvinylchloride composition (EN 585094A) have a high linear density of yarn, which makes them great weight, complicating their use.

Also known tarpaulin materials with double-sided coating for vehicles (GOST 29151-91)derived from polyester fabric with a plain weave with a linear density - 27,7-111 Tex with the number of filaments in a complex 48-192 and the number of turns 160-280 cu/m (art; 56303; 56235 according to GOST 26369-84, 27507-87, 27507-89 and THE 17-04-15-248-90). However, they also have the aforementioned disadvantages.

Known awning materials according to GOST 29151-91 and EN 2139963C1, EN-S performed on polyester fabric with a plain weave, made of filament yarn with a low number of filaments in the complex (about 48 filaments) and high twist 160-280 kr/m with double-sided PVC is th floor, not quite frost resistant (not higher than -45°C), which significantly reduces the efficiency of the finished material in static and dynamic conditions and do not meet the requirements of the Ministry of defense of the Russian Federation (table 3).

The objective of this invention is to provide a multi-layer covering, awning polymeric material suitable for use in the construction of prefabricated structures and shelters means of road transport in accordance with the requirements of the Ministry of defense of the Russian Federation.

The essence of the invention lies in the fact that as the basis for the multi-layered material consisting of polyester plackowatego canvas with double-sided coating, use polyester complex thread 100-111 dtex, number of filaments (filaments)=1) in the complex 200-400 and the number of turns 85-100 cu/m, while the mass ratio of the layers is personal: intermediate: wrong - 1,1:1:1,6 respectively, while the mass ratio of the polyester fabric and PVC coating is 1:2,7.

To achieve static and dynamic hardiness polymer-based coating suspension PVC with a constant of Fikentscher 70-72 additionally contains a mixture of plasticizer is dioctylphthalate (DOP) and dioctylsebacate (DOC); thermopl the partial polyurethane brand Vitart;

on BNR rubber stamps BNX-28; a copolymer of methyl methacrylate, butadiene and styrene brand KANE ACE WA in the ratio of 1:1,3:1,7:0,7:0,6 respectively. As the stabilizer is complex barium-cadmium-zinc stabilizer brand Vegetab BKC. Antivirusa Supplement is made in the form of a mixture of antimony trioxide and chlorinated paraffin stamps CP-1100 in the ratio of 1:1,fungicide-anilide salicylic acid.

The invention ensures cost effectiveness of the process, consisting in the selection of the most optimal operations of manufacture and inspection of the web proper, in the process of application of the coatings and the ultraviolet lacquer, the process of web tension synchronisation in various periods of its processing, the operations of linoleum web cooling, and other operations related to careful treatment of the covering, for example, during web rotation using the air cushion.

EFFECT: increased cost effectiveness of floor covering manufacture process.

FIELD: personal demand items.

SUBSTANCE: colour match is provided for the items containing various materials of bases. Composition of the coating is chosen so that it can be applied to various materials of bases thus in general maintaining equal visual characteristics of the item. Bases can contain flexible materials such as natural leather, synthetic leather, vinyl, foam, cloth and the like. The item includes the first base having the first flexible material, the second base having the second material different from the first material, the coating with colour match, which is made on the basis of solvent or on the basis of water dispersion of polymeric material, which contains polyurethane, and covers at least the section of the first base and at least the section of the second base. Examples of the items are footwear, automobile upholstery and automobile interiors. Manufacturing method of the item including the first and the second flexible bases made from various materials includes the following: the coating of at least the section of the first flexible base by the composition of the coating with colour match as per item 1 of the formula; and the coating of at least the section of the second flexible base by the composition of the coating with colour match as per item 1 of the formula.

EFFECT: there shall preferably be provided the composition of the coating capable of covering various types of bases of the item, and at the same time excluding the necessity of levelling colours.
