摘要

The use of hydrothermally treated cellulose pulp for the manufacture of cellulose fibres is described. Hydrothermal treatment allows for the preparation of cellulosepulp characterised by a polymerisation degree, DP, within the range of 290 - 405 and a low polydispersity Pd of 2.0- 3.0. A method of preparing alkaline solutions with a 7.45% content of cellulose, and alkali ratio of 1.05 is described. The impact of sulfuric acid concentration, the temperature of the coagulation bath, the as-spun draw of the fibre, the total draw ratio and drying conditions upon the mechanical properties of the fibres obtained was investigated. Trials at a high laboratory scale were conducted to spin multifilament cellulose fibres with a tenacity of 20 - 22.5 cN/tex and an elongation at break of 10 - 15%.
