Description

UNiTn STATES PATENT OFFICE.
HEINRICH LINNEKOGEL, OF STUTTGART, GERMANY.
METHOD OF TREATING RAMIE FIBER.
SPECIFICATION forming part of Letters Patent No. 679,508, dated July 30, 1901.
Application filed August 25, 1899- Selial No. 728,498- (No specimens.)
To aZZ whom it may concern.-
Be it known that I, HEINRICH LINNEKOGEL, physician, a subject of the King of Wiirtemberg, residing at 48 Kronenstrasse III, Stuttgart, in the Kingdom of VViirtemberg, Germany, have invented certain new and useful Improvements in Methods of Treating Ramie Fibers, of which the following is a specification.
My invention relates to improvements in the treating of ramie fiber in order to render it fit for the manufacture of shirts and other articles of wearing-apparel. By this treating of the fiber it is deprived of gummy matter and loses its brittleness.
For this purpose the ramie fiber is treated in the vacuum by means of soap, soda, (Na Go J glycerin, and pumice until all brittle substances are removed. The amounts of the ingredients are about as follows: one hundred kilograms of the dried ramie fiber; ten kilograms of soap, twenty kilograms of soda, (Na Oo ten kilograms of glycerin, and one kilogram of pumice. These substances are mixed with a sufficient quantity of water free of lime, and the mixture is boiled about twelve to sixteen hours. After that time the fiberis dried and then again drawn through a five-per-cent. solution of soap, while any particles of wood are removed by means of a fiveper-cent. solution of sulfuric acid. The object of the pumice at this procedure is to loosen the fibers by direct friction. By treating the ramie fiber this way the fibernow free from gummy matter becomes very hygroscopic, the shirts made of it gaining a high hygenic quality.
Having now described my invention, what I claim, and desire to secure by Letters Patent, is-
The method of treating ramie fiber for deprivin g it of gummy matter, consistingin mixing dried ramie fiber (about one hundred parts), soap (about ten parts), soda=Na Oo (about twenty parts), glycerin -(about ten parts), and pumice (about one part) with a sufficient quantity of water free of lime, boiling this mixture about twelve to sixteen hours, again drawing the fiber through an about fivepercent. solution of soap and removing any particles of wood by means of an about fiveper-"cent. solution of sulfuric acid.
In witness whereof Ihave hereunto set my hand in presence of two witnesses.
HEINRICH LINNEKOGEL. Witnesses:
WM. HAHN, H. WAGNER.
