Definitions
- the setting of the thread from the viscose solution can be effected-in known.manner, by the use of any of the commonly used setting baths.
- the viscose used can be of any age (or stage of ripeness), or can be fresh (1. e. directly after its original preparation).
- a art of the sulfur is set free, during the setting operation, in a very finely divided state, perhaps colloidal, on the surface of (and to some extent within) the threads or filaments. This ma exist as elemental sulfur, or as precipitate sulfur-containing byproducts, in-
- the silk is not, as is usually done, desulfurized before the bleaching, but (after washin out soluble acids and salts, if
- the dull, silk-like appearance of the fibre obtained in this manner is permanent and does not disappear even when the artificialsilk is dyed.
- the action of the adhering salts for the to formation of colloidal precipltations or deositions, on or in the silk fibres may be her increased by passage of the raw artificial silk through a suitable salt solution before the reviving '(scrooping, or toning), op-
- the bleaching may be performed with other bleaching agents that do not dissolve elemental sulfur, e. g. H 0 or numerous others. In some cases, as where the silk is to be (1 ed a dark color, the bleaching operation may e omitted.
- salts of these metals are of especial interest because the salts themselves and any insoluble com ounds thereof, formed in the process, are w its, and hence do not discolor the silk.
- the amount of salts is (in said bath, or a siparate bath if acid is not used) om 1 to 2% with respect to the bath.
- one effect of the salts in this bath is to prevent excessive action of the acid of this bath upon the silk, and in the present instance the salts in this bath react with the undesulfurized fibre to form white colloidal precipitations upon or in the silk fibres.
- K The silk is then treated in the usual toning (scroo in bath (say soap solution) until the silk sfiein just shows a. weakly acld reaction.
