Verfahren zum Entbasten der Seide durch Behandeln mit Wasser unter Druck.
Um der Seide den ihr eigenen Glanz und Griff zu geben, entfernt man bekanntlich ihren natürlichen Bast.
Diese Behandlung-Entbasten oder Entschälen, auch Abkochen genannt-geschieht allgemein in schwach alkalisch wirkenden Seifenbädern. Hierzu sind sehr grosse Mengen Seife, durchschnittlich 30 bis 35%, auf das Gewicht der Seide berechnet, erforderlich.
Es wurde nun die Beobachtung gemacht, dass Rohseide ohne jeden Seifenzusatz in sehr befriedigender Weise dadurch entbastet werden kann, dass man sie einige Zeit mit Wasser unter Druck behandelt, das Spuren alkalisch wirkender Stoffe, wie Ammoniak, Soda, Natronlauge, phosphorsaures Natron. Borax usw. enthält. Dieses Verfahren hat vor einem bekannten, bei welchem ohne alkalisch wirkende Stoffe gearbeitet wird, den Vorteil, besser zu entbasten und normale Flottenverhältnisse zu ermöglichen.
Die so behandelte Seide zeigt Glanz und Griff der nach den bisher üblichen Verfahren entbasteten Seiden.
Beispiel.

Process for deboning the silk by treating it with water under pressure.
In order to give the silk its own shine and feel, it is well known that the natural bast is removed.
This treatment - deboning or peeling, also called decoction - is generally done in mildly alkaline soap baths. This requires very large amounts of soap, on average 30 to 35% based on the weight of the silk.
The observation has now been made that raw silk can be deburred in a very satisfactory way without any addition of soap by treating it with water under pressure for some time, leaving traces of alkaline substances such as ammonia, soda, caustic soda, sodium phosphate. Contains borax, etc. This process has the advantage over a known process, in which no alkaline substances are used, of better deboning and enabling normal liquor ratios.
The silk treated in this way shows the luster and feel of the silks which have been debaffed by the methods customary up to now.
Example.
