(54) DUBBLED RUBBER-TEXTILE MATERIAL

Iboretenve relates to new layered materials, specifically to tanned material, including low aul cellular rubber and high stretch knit fabric, and can be used to create hydrostatic sports and tourist products. I have no medical purpose. A layered material is known that contains high-tensile oriented oriented nipon junction coupled with sing rubber. In the space between the layers of nylon and rubber, an adhesive is introduced that ensures the adhesion of the material 1 J However, this material does not have high stretchability either in the transverse direction in the longitudinal direction and cannot be used for the manufacture of wetsuits, sports and tourist products, or medical equipment. does not provide free movement of the limbs and the human body. The closest to the proposed duplicated material is a laminated rubber-textile material, including a layer of nonsmountable chevou rubber and a base — a knitted high stretch fabric, in a ratio by weight respectively 0, 6-O, 75: O, 25- 0, 4O, while the knitwear is made up; polyamide yarns - nylon. C23 However, this material also does not possess high extensibility in the longitudinal and transverse directions51X1 In addition to Toroj, it has low physicomechanical indicators. The aim of the invention is to increase the extensibility of the material in the transverse and longitudinal directions; Delivered gel is achieved by the fact that in a duplicated rubber-textile material, including a layer of low-modular cellular rubber and a basis-knitted high-growth fabric in the ratio by weight, respectively, О, 6-0.75: О, 25-О, 4, knitted fabric

You can shortly insert the spandex on the basis of polyurethane into the threads selected from the brackets: elastic m based on textured polyamide; cotton, modkf1shv | th vavvyh polyamide-based

copolymers of polyamide with even vertical polydimethylaminoethyl methacrylate, with a ratio of 1: 2-3 in the canvas

Examples 1--4. To obtain the proposed duplicated material, high-stretch knit fabric based on ivite spandex and elastic or cotton yarn, or yarn based on modified polyamine fiber is applied by a two-phase spraying method followed by heat treatment at 120 ° C for 2 rubber mixture based on chlroprene rubber type KR-50 and a pore-forming agent - Easter P1b-55 (dinitrosopentamethylenetetrammine) As a mixture using chloroprene-based mixture

Item 2714ОЗ is a nylon-based knitted fabric used for the manufacture of duplicate material used in industry.

High-growth knitted fabrics are made on the basis of two-contour kulir weaves of the following vtsdov: eraser 1: 2, eraser 1: 3, pc on the round-fang mask Multikolor. The process increases the cupping depth (loop length) by the amount of reverse deformation of the elastomeric fiber spandex and changes the tension of its tension when fed to the knitting machine. that provides good adhesion to the rubber during the subsequent application of a layer of cellular low modulus rubber to the knitted fabric. The properties of knitted fabrics and duplicate materials obtained on their basis are given in Table. 1 and 2.

Article 27403, dubbed material .. ’Claims. ' A rial based on such a knitted fabric manufactured in industry is selected as the basis for comparison. As can be seen from the data given in table. 1 and 2, the duplicated material obtained according to the invention, surpasses all known samples in elastic properties. <o Elongation in length is more than 80% compared with industrial samples of duplicated material. In width, this indicator is higher for known samples by 50-60%, i.e. the resulting material has large values of elongation in the longitudinal and transverse directions. : Improving the properties of the duplicated material is achieved when the ratio of rubber and canvas 0.6-0.75: 0.25-0.40. If these ratios are not observed, the extensibility of the duplicated materials deteriorates either in width or in length. The use of this material for the creation of wetsuits, sportswear, medical supplies can improve the working and rest conditions of lindens associated with work in contact with water. Duplicated rubber-textile material, including a layer of low-meshed cellular rubber and a base - knitted highly extensible fabric in the ratio by weight, respectively (0.6—0.75): (0.25-0.4), characterized in that, in order to increase the elongation of the material in the longitudinal and transverse directions, the knitted fabric is made of spandex yarns based on polyurethane and yarns selected from the group: elastic based on textured polyamide, cotton, modified polyamide based on grafted copolymers of polyamide with black - 'vertichnymi polidimetilaminoetylmetakrilata salts, at a ratio in the web 1, respectively: (2-3).
