Abstract:

A process to produce fibres from bio-modified cellulose pulp has been developed. The spinning process was investigated on a large laboratory scale. Alkaline spinning solutions were first prepared from enzyme-processed cellulose, followed by wet spinning. In the course of this research, the physical-chemical properties of the bio-modified cellulose (including its solutions), were estimated. We studied the dependence of the mechanical properties of the obtained cellulosic fibres on the composition of the coagulation bath, and on process conditions such as spinning speed. Cellulosic fibres could be manufactured which were characterised by tenacity in the range of 17-19 cN/tex and an elongation of 12-13%.
