Description

GIUSEPPE GIANOLI, OF MILAN, ITALY.
PROCESS OF CHARGING SILK.
Specification of Letters Patent.
Patented May 8, 1906.
Application filed January 4,1905. Serial No. 239.654.
To all whmn it may concern:
Be it known that I, GrUsEPPE GIANoLI, a subject of the King of Italy, residing at Milan, in the Kingdom of Italy, have invented certain new and useful Improvements in Processes for Dyeing or Charging Silks with Tin Compounds, of which the following is a specification.
It is well known and has even been the cause of complaint that silks charged with salts of tinwhich is the material usually em loyed for this purpose-are subject to suc alteration in their physical and mechanical properties that after a very short space of time they will tear even upon a slight pull. More especially is this the case when such silks are exposed to light. The importance of this loss of resistive power has been demonstrated by the researches made in the laboratory of the Socita Anonima Cooperativa per la stagionatura e lassaggio delle Sete ed affini in connection with silk (see Ammo/ire of the S ocitd Chimica of Milan, sitting of the December 4, 1897) and by the researches of Professor Gnehm and Dr. Banziger. (See Fc'irber Zeitung of 1897.) As it was the intention to study the causes of these alterations produced insilk charged with the abovementioned compounds, various forms of tin combinations were tested, and it is found that by using sulfo-cyanic acid and its salts and derivatives the silk fiber retains its dynamometric qualities almost unchanged.
The application of the sulfo-cyanic acid and of its salts is effected during the operations of charging, dyeing, or clearing by means of a diluted solution, (varying from 0,5 to three per cent. and more.) Having exposed to the action of light for ten days some small skeins of silk (organzin) charged with thirty per cent. in excess of its original weight, a portion of which had been subjected after dyeing to clearing by the aid of one per cent. of sulfo-cyanate of ammonia rendered acid by means of sulfuric acid, whilethe other portion had been cleared or brightened by the ordinary method in an acid bath by means of 1:1,000 (one per thousand) of sulfuric acid, the following results were obtained:
Tenacity. Elasticity.
G'rams. Millimeters. Skein charged without the addition 43,32 57 of sulfo-cyanate. Skein charged with the addition of 63,88 135 sulfo-cyanate.
It will be understood that either the sulfocyanic acid, its salts, or its derivatives may be used.
Having now particularly described and as certained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is In the process of mordanting or dyeing silk, acting on the silk with an alkaline sulfocyanid and an acid in solution of approximately one to three per cent, substantially as described.
In witness whereof I have hereunto set my hand in presence of two witnesses.
GIUSEPPE GIANOLI.
