FIELD: textile, paper. ^ SUBSTANCE: bundles of fibres with a total denier of 10000 to 500000 dtex is obtained by binding thermoplastic, conjugate, continuous fibres, which have an individual fibre denier of 0.5 to 100 dtex/f and whose center of gravity of conjugate components varies between the conjugated components in the cross section of fibre. Thermoplastic, conjugate, continuous fibres composing a bundle of fibres have existing coils from 8 to 30 threads per 2.54 cm. Density of bundles of fibres ranges from 100 to 2000 dtex/mm2 and is determined according to dependence of the D1/(W1xL1), where D1 is a total denier, W1 is width of bundle of fibres and L1 is a thickness of bundle of fibres. The ratio of canvas density after stretching the bundle to the bundle density is equal to 0.10 or less. The method of producing fabrics comprises the step of pulling the said bundle of fibres with an extraction coefficient from 1.4 to 3.0. Canvas with a total denier from 10000 to 1000000 dtex contains thermoplastic, conjugate, continuous fibres aligned in one direction and have an individual filament denier of 0.5 to 100 dtex/f and whose center of gravity of conjugate components varies between the conjugated components in fibre cross-section. Thermoplastic, conjugate, continuous fibres have spiral circuits from 10 to 100 circuits per 2.54 cm. Density of canvas ranges from 5 to 80 dtex/mm2 and is determined from the dependence of D2 / (W2xL2), where D2 is total denier, W2 is a canvas width, and L2 is canvas thickness. Presence on the fibres of more than 100 spiral circuits per 2.54 cm at a canvas density from 10 to 100 dtex/mm2 is possible The item is made of canvas. In the product the canvas is combined with the help of a set of partial sections of thermal bonding with another canvas or coating without spiral circuits, or with other canvas or coating with less spiral circuits. Loop from which a different fabric or coating extrudes is formed between the partial areas of thermo-attachment. The product can contain many components with fibre length from 3 to 50 mm, thermally attached with the parts to canvas or covering that serves as the base. With the use of a part or a product the final product is received. ^ EFFECT: obtaining the bundles which is capable of wrapping in the structure with a high density of fibres and which has properties ensuring uniformity of canvas, its high volume and soft tactile properties. ^ 9 cl, 2 tbl |
