Title: Improvements in the treatment of cellulose and the obtainment of an improved product
IPC: D06M11/09
Filed: 1923-03-29
Abstract: Artificial silk is rendered more resistant to the wetting action of water by treatment with dry chlorine whilst avoiding the presence of moisture; the chlorine may be employed as a gas or dissolved in an organic solvent such as benzene.  The water-resisting properties of the material are increased by treatment with wax, and this treatment may take place subsequently to or simultaneously with the treatment with dry chlorine; the wax may be dissolved in the solvent for the chlorine.  In the examples the material to be treated is subjected to a more or less prolonged preliminary drying operation.
