Definitions
- a preferred method of drying spun cooled fibers consists in drawing off the spun and water cooled fiber or fiber bundle respectively from the take up roller or rollers by means of an ejector with an extended difiusor, said ejector being driven by hot air or gas, streaming with such a speed, that the fiber bundle is easily separated from the surface of the last take up roller without being oriented by stretching.
- the temperature of air or gas respectively introduced into the said ejector is preferably chosen so high, that the fiber is dried in a very short period of time, durin which the fiber The fiber bundle is then coiled up in usual way and subsequently treated by cold drawing, twisting etc., which operations may be carried out in any desired succession.
- the fiber bundle is led from the spinneret over a grooved cylinder 2, concurrently with water running on its surface and then through a system of take up rollers 3 into the ejector 4.
- the inlet 5 is fed with nitrogen, preheated up to 200 C. under a starting pressure of 5 kg./cm. so that the gas speed in the diffusor 5 reaches several hundreds of m./sec. and gives to the fiber bundle the tension necessary for separating it from the take up rollers 3 without stretching it up to the linear orientation.
- the fiber bundle is then coiled up or treated in any other unshown way.
- the tensile strength of fibers e. g. of those from polymerized G-caprolactam, scribed treatment from 5 g. up to 6.8 g./ den.
- the drying may be carried out in any other suitable way, e. g. by using radiant heat and, if desired, by simultaneously using reduced pressure.
- a method for producing artificial filaments from molten high molecular fiber-forming materials which are capable of being oriented by cold drawing comprising the steps of spinning said material; cooling the thus spun material by bringing a. liquid into contact therewith; drying the thus cooled material; and cold drawing the thus dried material.

- a method for producing artificial filaments from molten high molecular fiber-forming materials which are capable of being oriented by cold drawing comprising the steps of spinning said material; cooling the thus spun material; drying the thus cooled material by means of an ejector provided with a long diffusor and fed with a heated gaseous medium, said gaseous medium streaming with such a speed that the material is moved through the ejector without being linearly oriented; and cold drawing the thus dried material.
