PROCESS AND DEVICE FOR THE TRANSPORT OF CONTINUOUS MOLDINGS WITHOUT TENSILE STRESS |
摘要 |
The invention relates to a method for producing extruded, cellulosic continuous shaped bodies from an extrusion solution containing cellulose, water and tertiary amino-oxide. In order to improve the textile properties o f the extruded continuous shaped bodies with regard to the prior art, the invention provides that the continuous shaped body (5) is conveyed, with essentially no tensile stress, on a conveying device (11) between an extrusi on nozzle opening and a take-off unit (24). To this end, the speed of conveyanc e of the interconnected conveying device (11) is preferably less than the extrusion rate and less than the take-off rate of the take-off unit (24). By employing these measures, the textile properties such as loop strength and tendency to fibrillate can be considerably improved.
