Definitions
- the spinning solution e. g. the viscose solution
- the chemicals used form a homo- 1geneous mixture with the regenerated celluose.
- the normally prepared spinning solution is spun andthe silk obtained is submitted to a subsequent treatment which causes a precipitate to settle on the fibre, causing the silk to look dull.
- This precipitate may consist of an insoluble salt, e. g. an inorganic salt like barium sulphate or an organic salt, such as fatty acid salts of aluminium.
- the fibre is submitted to aswelling process by means ofconcentrated sulphuric or phosphoric acid, chloride of zinc, and such like substances.
- a lasting aftertreatment which, like the method mentioned sub 4 is based on ahydrolysis, may be obtained by treating the silk with a solution of suitable silicofluorides in water which are capable of separating silicic acid when heated.
- a very suitable silicofluoride for this purpose is magnesiumsilicofluoride (MgSiF tSH O). This silicofluoride is easily soluble in cold water (1:1.5) and gradually separates silicic acid when heated, the silicic acid being dissolved again after cooling.
- this process is based on the principle that the silicic acidseparated by heating is partly incorporated into the silk, in such a. way that it cannot be washed away, when the silk is rinsed with water, or treated with diluted acids or soap solutions.
- the silk to be treated is introduced into a cold solution of the silicofluoride; then the temperature of the bath is gradually raised.
- the silk is taken from the bath, and thoroughly rinsedLwith water.
- the resulting silk can immedlately be dyed or dried.
- the product obtained in this way is a dull, milky white silk, which may easily be moistened, and submitted to a further treatment.
- the dull silk obtained according to themvention is, however, not quite proof agalnst a hypochlorite solution, as by a treatment oi: the silk with such a solution the lustre is partly restored.
- the lprocess of providing artificial silk with a du l lustre which comprises introducing the finished silk into a, solution containing magnesium silico fluoride and heating the said solution.
