Description

UNITED STATES PATENT OFFICE.
EMILE BRONNER'I', or mumrousn, Alsace-LORRAINE, Eamon.
MANUFACTURE OF ARTIFICIAL VISCOSE 8111K.
1T0 Drawing.
To all whom it may concern:
Be it known that I, EMILE BRoNNnnT, a
' citizen of the Republic of France, residing the spinning bath, it is preferable and more at 1 Quai du Barrage, Mulhouse, Alsace- Lorraine, France, have invented certain new and useful Improvements in. the Manufacture of Artificial Viscose Silk, of which the following is a specification.
A process for spinning very. fine threads from viscose solutions has been proposed, in which spinning baths containing aldehyde bisulfites or the reduction products thereof, ketone bisulfites or soluble condensation products of phenols with aldehydes and sodium-sulfitesare employed.
Now it has been found that instead of adding these water soluble combinations to economical to add the various condensation products of phenols and aldehydes soluble in alkali, to the viscose itself, preferably prior-to the ripening process, and to force the suitably ripened mixture into bisulfitebaths for example. 25
Example.
10 kg. artificial resin produced from phenol and formaldehyde are dissolved in about 3.6 kg. caustic soda and 43 kg. water and-then 1000 kg. freshly prepared raw viscoseare added.
A homogeneousmixture of the above constituents is subjected to the usual ri ening and then worked up into threads in the usual manner, use being made of a warm concentrated bisulfite bath. The feed of material is at the same time regulated to correspond to the desired fineness of the single threads and to the corresponding necessary drawing ofl' speed. Apertures say of 0.10 mm. can be used, but also finer or larger onesrnay be employed, in taking in consideration the chosen viscosity of the viscose. i
The concentration of the spinning baths must be the greater the finer the titre of the thread is desired. For ordinary threads of Specification of Letters Patent. Application filed September a, 1920. Serial No. 468,967.
filed August 31, 1920.
Patented Apr. 12, 1921.
' same dyes or coloring materials-darker than the products obtained from raw viscose and without addition of other materials. A pos sible explanation is that the residue of the products precipitated out by the acid act as a mordant. Also theresistance to water is somewhat higher than with viscose threads spun from viscose alone without the additions in question.
. The broad idea of precipitating viscose in bisulfite baths, the concentration of "which isjnversely proportional to the thread fineness tobe produced, is not herein claimed, as said matter is claimed broadl in my copending application, Serial I claim:
The process of producing artificial viscose silk threads up to 1 denier in fineness, consisting in that raw viscose with alkaline condensation products of phenols and aldehydes [are spun in bisulfite baths, theconcentration of the baths being inversely proportional to the threadfineness to be produced.
In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses. l
EMILE BRONNERT.
