FIELD: cellulose industry.
SUBSTANCE: invention relates to a spinneret pack and to a method for the production of lyocell, in which such a spinneret pack is used. The spinneret pack is made of a rectangular shape, with the ratio of sides of more than 2, and it contains at least a cover, a case of the spinneret pack, a distribution lattice, and, optionally, separate spinneret plates in the case of the spinneret pack. Moreover, at least the cover and/or the case of the spinneret pack are heated using vapor with a temperature in the range from 105 to 138°C and pressure from 1.0 to 4 bar, and the distribution lattice is made of material with specific heat conductivity of more than 50 W/(m*K), preferably 80 W/(m*K).
EFFECT: specified spinneret pack, especially with high throughput capacity and high speed, provides proper uniformity of elementary threads.
