Abstract: | Conclusions -- Two lots of cellulose, from pine wood and from larch, have been developed; these were treated in the first stage of bleaching with oxygen in alkaline medium instead of by chlorination, under experimental conditions.-- From a preliminary evaluation, the process of viscose preparation and preparation of the viscose for spinning under experimental conditions took place without significant deviations from the accepted technological regime. Higher technological indices of the viscose from pine cellulose were noted.-- The process of spinning viscose fibre from experimental lots of viscose from larch wood and from pine took place in a stable fashion; no clogging of the spinnerets was observed.Translated from Khimicheskie Volokna, No. 5, pp. 17–19, September–October, 1990. |
