MANUFACTURE 01E ARTIFICIAL SILK.
acogrsi.
No Drawing.
Specification of Letters Patent.
Patented June a, rare Application filed January 24;, 1910. Serial No. 539,738.
To all whom it may concern:
Be it known that I, HENRY BERNSTEIN, a
' citizen of the United- States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and use ful Process for Washing Cellulose Filaments, of which the following is a specification.
My invention relates to a new and useful process for washing cellulose filaments and consists in subjecting the same to a bath of water from 25 to 50? 0., whereby the after washing is avoided.
,by the compounds of cellulose are so opened up that'the after-washing with acidified water becomes unnecessary.
Inplace of sprinkling the cylinders containing the cellulose filamentswith acidified water I subject these revolving cylinders to warm water at'25 to 50 in the form of vapor or fine spray under pressure of air which is brought close above the surface of the material on the cylinders.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
1. In the manufacture of artificial silk, the process of washing out the remnant of solvent from the cellulose filaments which have been formed b s' inning the cuprammonium solution ce lulose into an acid which consists in winding the filaments on cylinders in suitable vessels and moving the said cylinders in a bath of warm water at to 50 0., whereby the cellulose compound is opened up and lastly washing the same in plain water.
2. In the manufacture of artificial silk, the process of washing out the residuevof metallic salt from the cellulose filaments spun from cuprammonium solution of cellulose which consists in winding the cellulose filaments on spools, moving said spools,
and then subjecting the said filaments to a vapor or fine spray of water at 25 to 50 C.
under pressure.
