No Drawing.
To all whom it may concern:
Be it known that I, PETER SoHMm, a citizen of the Swiss Republic and resident of Basel, Switzerland, have invented a new Process for Producin Foam or Froth Bat s for Ungumming Silk and Silk-Wastes, of which the following is a full, clear, and exact specification.
It 1 known that the ungumming' of silk and silk wastes in all forms, as raw goods, spuns or tissues, was heretofore obtained b holding the goods for a certain time in boi ing soap water or in lather bath produced by heating soap water or soap water containin chrysalids.
f have now found an even cheaper process for producing a foam or froth bath for ungumming silk and silk wastes, which consists in heating, to the boiling oint, a weakly alkaline water bath containing only sericin as the foam producing substance.
Such an ungummlng bath can, for instance, be prepared by adding a little alkali to the sericin water obtained by washing silk previously treated with soap lather bath, so that an alkiline bath is obtained, containing Specification of Letters late'nt.
for instance for 100 kg. water, 25 gr. sodium carbonate and 200 gr. sericin. constitutes, when transformed into froth or foam without addition of soap, a very efl'ective and extraordinarily cheap unigumming bath wherein the sericin froth or 0am carries the alkali.
What I claim is:
1. A process for producing a 'foam or froth bath for ungumming silk and silk wastes, consisting in heating to ebullition a weakly alkaline water bath containing only sericin as a foam producing substance.
2. A process for producing a foam or froth bath for ungumming silk and silk wastes, consisting in heating to eb-ullition a feeble watery solution of sodium carbonate containing only sericin as a foam producing substance.
In witness whereof I have hereunto signed my name this 12th day of May, 1917, in the presence of two subscribing witnesses.
