| titleOfInvention | Procedure and device for the formation of cellulosic networks formed directly |
| abstract | A process for making cellulose-based nets that are formed directly from a lyocell spinning solution comprising: a. an extrusion step using an extrusion device (1) capable of extruding a plurality of lyocell solution strands, in particular arranged in one or more rows to form a curtain, and also capable of spreading the solution strands, b. a first washing step carried out in a first washing zone with means (7) for supplying washing waters to the strands of the solution directly after extension and before the formation of the network, whereby filaments are formed partially coagulated cellulose, c. a net-forming step carried out in a net-forming zone with a net-forming device (4) on which the partially coagulated filaments are placed to form a net (11), wherein the net-forming device formation of the network (4) has sufficient porosity to allow the gas stream and washing waters to be extracted through it, d. a second washing stage carried out in a second washing zone with a washing device (5) that includes multiple modular washing modules (2), where e. each washing module (2) comprises a means (9) to apply washing liquid to the network (11) uniformly as a curtain of water closed over the entire width of the network with respect to the network at a controlled rate and temperature and with a sufficiently low force such that it does not damage the structure of the network and the coagulated filaments and the dewatering device (10) to at least partially dehydrate the network (11), and f. a means (6) for collecting the washed net (11) or for transferring the net (11) directly to the subsequent processing stages, and g. that the process can be operated at line production speeds of the formed network (11) from 5 m/min to 1,000 m/min and h. that the wash liquors are water, a water/amine oxide mixture or other suitable liquid to remove the solvent. |
