Abstract

529,050. Artificial filaments. COURTAULDS, Ltd., and AVERNS, H. M. May 10, 1939, No. 13969. [Class 2 (ii)] Curled monofil is obtained by extruding a solution of a cellulose derivative downwards through an orifice into an evaporative atmosphere, directing a steady continuous current of evaporative medium on to one side of the extruded solution just below the orifice and allowing the resulting filamentary product to fall under its own weight, without subjecting it to any other tension, on to a collecting device. The cellulose derivative may be cellulose acetate and a solution of 25 per cent. strength may be used. Each jet may have one or more orifices through which the solution is extruded to form one or more curled monofils. When there are several orifices they are spaced so that the issuing streams of solution do not contact before a substantial proportion of solvent has evaporated. Warm air at 30‹-65‹C. may be used as the evaporative medium. The evaporative medium directed on to one side of the extruded solution may be at a higher temperature than that of the main bodyof evaporative medium. The cross current may be obtained by introducing air through a tube, the outlet of which is on one side of the extruded solution, or by applying suction to a tube situated on the opposite side of the solution. The monofil may be collected on a plate, box, platform, table, or transport belt. The collecting device may be heated. As shown, cellulose acetate solution is extruded through jet 2 provided with a single orifice 3 into air at a temperature of about 30‹C. circulated by means of inlet and outlet pipes 4, 5, through a cell 6. The falling monofil is collected on a slowly moving band 8. Air at 65‹C. is introduced through tube 9 and is directed against one side of the extruded solution.
