FIELD: textile, paper. ^ SUBSTANCE: this invention refers to method and device for manufacture of polymeric fibres and textile products in a closed system. System for manufacture of non-woven cloth from fibres includes a spinning beam unit configured for processing and supply of many flows of polymers for extrusion through the spinning nozzle holes. At that, spinning beam unit includes many supply passages interconnected as to fluid medium with the spinning nozzle holes where at least two supply passages are configured so that they can supply separate flows of polymers with various polymeric components to the spinning nozzle holes. Besides spinning beam unit includes many collectors for separation and independent keeping of various temperatures for various flows of polymers with various polymeric components. Each collector provides homogeneous heating of polymer flow flowing inside discharge pipe of polymer inside each collector, each discharge pipe is enveloped with heat exchange pipe in fact at homogeneous temperature, quick cooling chamber for receiving and quick cooling of extruded fibres from spinning nozzle holes. At that, quick cooling chamber includes gas supply source for direction of gas flow to extruded fibres. Also the system includes an exhaust chamber interconnected with quick cooling chamber and configured for receipt and release of quick cooled fibres, and a forming surface for receipt of extruded fibres leaving the exhaust chamber and forming of non-woven fibrous cloth on the forming surface. At that, system supports extruded fibres in closed space between the spinning nozzle holes and exhaust chamber so that contact of fibres to uncontrolled gas flows can be prevented. ^ EFFECT: simplifying the fabrication of wide range of fibres from variety of polymeric components and textile products having the required linear density of fibre (denier) and degree of homogeneity. ^ 8 cl, 9 dwg |
