Definitions
- NAAMLOOZE VENOOTSCHAP NEDERLANDSCHE 'KUNSTZIJDEFABRIEH. OF ARNHEM. NETHERLANDS.
- ()ur invention relates to a process and apparatus for the manufacture of artificial silk and other artificial textile products from cellulose solutions by the dry or evaporw tive method.
- cellulose solutions whenever used in this specification and the claims is intended to cover solutions of cellulose compounds, such as cellulose nitrate, cellulose acetate, alkyl, aryl, and aralkyl cellulose and other mixed or single esters and ethers of cellulose, in ether, acetone, alcohol-ether,
- the air in the casing was heated, for instance by arranging heating spirals in the lower part of the casing or metiel'x
- the heated air ascended'and was removed, together with the vapours of the volatile solvent, in the uppermost part of the casing. Further it. has been proposed to apply no heating in the casing and to carry out the 60 Winding of the spun material in a second,
- this second casing being heated and serving for further leading off the evaporated solvent to a regenerative apparatus for this solvent.
- the process according to our invention shows the characteristic that the cellulose solutions are extruded through fine appertures in a downward direction into a slowly ascendingmedium, whose temperature increases gradually in an upward direction.
- the process according to'our invention may be carried out also in a casing which is open at. the lower part thereof.
- the slow' as rent of the medium in the casing is preferably regulated or controlled by means of an outlet arranged at the upper part of the casing.
- our invention comprises an apparatus for carrying out the novel process consisting in a vertical or practically vertical casing which is wholly or practically whooly surrounded by heating means, and which contains an outlet at the upper part in proximity to the outlet openings for the cellulose solution.
- the casing is preferably open at the bottom.
- This casing 1 is a vertical metal casing of about 2 metres length and a cross section of about 25 centimetres.
- This casing 1 has 'at the upper part an opening through which leads a. supply pipe 2 for the spinning solution.
- a known spinning pump 3 is arranged, which leads the spinning solution with controllable velocity through the pipe 2 to the spinning nozzle 4.
- the spinning liquid leaves the spinneret 4 and descends through the slowly ascending atmosphere in-the casing 1; the spun material 5 is wound up by winding device 6 and may be twisted at once. If desired the spun material 5 may be led away by means of a guide 7..
- a jacket 8 in which circulates a liquid or other heating medium entering at 9, and flowing off at 10. By regulating the temperature of this heating medium in connection with its velocity a temperature gradually decreasing from the top in a downward direction is obtained.
- a suitable range of the temperature is for instance that at the upper part of the casing a temperature of about 50 and at the lower part of the casing a temperature of about 20 C. prevails.
- Our invention in the first place provides a simple apparatus which is easy to handle and easily accessible.
- the second place it is possible to wind up in a place perpendicular beneath the spinneret, a moving thread guide being even superfluous, this forming a further advantage of our invention.
- ⁇ Vhen we refer to a casing open at its lower end we mean a casing having a large hole at its lower end, as distinct from an orifice e. g. a casing having the form of an inverted closed cylinder.
- Apparatus for carrying out the process of manufacturing artificial silk and other artificial textile products from cellulose solutions according to the dry or evaporative method consisting in a practically vertical casing which is at least for the greater part of its length and particularly toward its upper end, surrounded by a heating means the temperature of which increases from the bottom to the top, the casing having an outlet for the ascending medium provided with a regulating or controlling means and in proximity to the apertures for the cellulose solution.
- An apparatus for carrying out the process of manufacturing artificial silk and other artificial textile products from cellulose solutions according to the dry or evaporated method consisting in a' practically vertical casing which is at least for the greater part surrounded by a heating jacket having an inlet at the top and an outlet "-near the bottom, the casing having an outlet for the ascending medium provided with a regulating or controlling means and method; consisting in a practically vertical v casing which is for the greater part at least surrounded by a heating jacket having an inlet at the top end and an outlet near the bottom end, the casing having an outlet for the ascending medium provided with a regulating or controlling means and in proximity to the apertures for the cellulose solution and being open at its bottom end.
