Application filed July 13, 1929, Serial No.
The invention relates to thetwisting and reeling of artificial silk or the like and more particularly to artificial silk which is already wound on twisting spools in a damp condition.
In the production of artificial silk in accordance with the reeling process the filaments expressed through fine openings out of a thick liquid substance such as viscoseare led direct into a coagulating liquid. The cellulose tissues which result are wound on rotatin spools, bobbins, or similar devices and su sequently undergo a long washing process in orderto remove the adhering acids and salts. The washed spools are dried, the
artificial silk filament is twisted off and .finally reeled.
This process is inconvenient, tedious, and requires a, large number of bobbins and go further, on account of the diverse and separate operations which are necessary a large e enditure of operating power is necessary.
11 certain cases the freshly spun unwashed viscose filament is twisted ofli' direct from the bobbins and is guided on to reels,the filament on its passage from the bobbins to the reels being passed through the washing liquid in order to remove the adherent impurities.v
During such a processthe rotating bobbin is continuously subjected to the action of water spray and the twisted filament is guided on to the reels by means of filament guides located in the atmosphere.
Duringthe twisting processby virtue of the centrifugal movement the damp filament drawn ofi the twisting bobbins loses a part of its moisture-and becomes sticky so that on its passage through the filament guides certain parts of the filament more easily adhere the filament and rendering the artificial silk of poor quality.
One object of the invention is to provide a method of twisting and reeling spooled damp artificial silk which avoids the adherence of the individual filaments to one another.
A further object of the invention is to provide a method of twisting and reeling spooled damp artificial silk wherein the silk .is subto the guides thus producing breakages of 377,956, and in Germany March 15, 1928.
mitted to a washing and protective action prior to reeling.
The method of thepresent invention consists in drawing off the filament from a twisting spool, allowing the drawn 01f twisted filaspinning process precipitants which, as far as gossible, do not crystalize out.
s the artificial silk when'damp is especially sensitive to mechanical treatment it is preferred to add to the liquid through which the filament passes substances adapted to form protective layers on the filament during its passage therethrough such as wax-oil emulsions.
The invention is more particularly described with reference to-the accompanying diagrammatic drawing.
Referring to the drawing (1 denotes the twisting bobbin which is located at the lower end of a rotating shaft driven by means of a belt or the like. The filament is drawn off the bobbin a over the head thereof and is drawn down'by means of the rotating reel d at the same time being. correspondingly twisted. The filament falls freely into a steeping bath 0, passes through a filament guide or guides b in the liquid over the guide 6' and is wound up on the reel 05 in the form of a skein. l
The damp artificial silk hank thus wound on the reel is unbound, removed from the reel, washed and prepared in the usual manner.
What I claim is p 1. A method of treating a spooled damp artificial silk filament which comprises removing the damp filament from the spool while rotating the spool to impart twist to the filament, winding the filament on a reel,
A guiding the filament between the reel and the 'spool byn'leans of a. guide immersed in a liquid body and providing unconstrained movement of the filamentfrom the spool to. the liquid bodyr '2. A methodof treating a spooled damp artificial silk filament whichicomprises removing the damp filament-from the spool while rotating the spool to impart twist to the filament and disengaging moisture from the filament .due to centrifugal action, winding the filament on a reel, guiding the -filament between the reel and the spool by guides including a firstguide immersed in a body of liquid adapted to. form a protective layer on said filament and providingunconstrained movement of the filament from the spool to the; liquid body. j I
