FIELD: textile industry. SUBSTANCE: method involving extruding cellulose dissolved in a tert- amine oxide through spinneret holes and transferring stretched extruded elementary threads through air channel into precipitation bath is distinguished by that method is carried out such as to obtain 10 from solving the following expression: 51.4+0.033D+1937 M 2 -7.18T- 0.094L-2.50F+0.045 F 2 , where D is hole diameter, mm; M displacement of spinning mass per one hole, g/min; T titer of single thread, dtex; L width of air slot, mm; and F humidity of air in air slot, g of water per 1 kg of air, on condition that width of air slot exceeds 30 mm. EFFECT: enabled fabrication of fiber with insignificant propensity to fibrillation. 6 cl, 4 tbl, 54 ex |
