Definitions
- the subject of this invention is a process for metal Salt, of Commercial CuSOi tol 1 collecting artificial silk in the usual spinning litre of water, or? g. of commercial MgSO4 to 1 pots.
- the process consists in weighting the fine litre of water, interacts with the substances still 25v filaments in a suitable manner before introducremaining behind from the precipitation the tion into the spinning pot. Even in the case of products whereof are insoluble salts which pre extreme fineness, such weightedfilaments are cipitate on the filament and are only dissolved drawn smoothly into the spinning pot and are out again in the spinning pot, intothetop'of wound to a'perfectly satisfactory cake. I which acid is introduced.
- the weighting is best efiected by producing For forming the precipitate those quantities of a precipitate on the fibre, the freshly-spun filasalt solutions are preferably usedwhich are necment being treated with solutions of substances eSSary r interacting Wi h everytrace of the which react with the substances derived from Sub a p sent in the filament.

- Those compounds which can interact to dIOXid-B Present i theyfilalment fl d ng. t0 the form comparatively heavy compounds are parfo w equations! a 1 I ticularly suitable.
- spun cakes to be made in spinning pots of much choose those solutions which react with the sub- 50 diminished rotational speed when spinning artistances on the filament and precipitate insoluble 7 ficial silk filamentsof the usual titre.
- the speed substancespn the latter, thereby weighting the of rotation is smaller so that the spinning pot is filament, which insoluble substances are removed considerably protected. Also the power required only subsequently, after they have performed:
