UNITED STATE S PATENT OFFICE.
PETER SCHMID,'OF BASEL, SWITZERLAND.
PROCESS OF RENDERING JUTE AND LIKE FIBROUS MATERIAL 'WOOLLY.
No Drawing.
To all whom it may concern:
Be it known that I, PETER Scin'no, a citizen of the Swiss Republic, and resident of Basel, Switzerland,-have invented new and useful Improvements in Processes for Rem dcring Jute and Like Fibrous Material \Voolly, of which the following is a full, clear, and exact specification.
It is known to render woolly jute and like fibrous material by means of caustic lyes. On the other hand, it is known to treat jute fibers thus previously prepared after washing with concentrated emulsions obtained by a more or less complete saponilication of olive-oil with potash lye.
The subject of the present invention is a process for rendering woolly jute and like fibrous material, which rests upon the obser vation that by the substitution for said emulsion baths, of soap foam baths the librous material thus treated by the latter gets a finer, more wool-like touch or gripping. 'lhefollowin examples illustrate the process for treating in this way decorticatctl jute or like fibrous materials;
Example 1: The jute is treated according to its nature and to the desired degree of bleaching with a solution of hypochlorite of 5 degrees 136., or more during 10 minutes till up to 4: hours. It is then pressed out to eliminate as well as possible the hypochlorite out of the material. Then the material is laid during 5 minutes or more in caustic lye of 30 degrees and pressed out again.
Thereupon, it is treated during 5 minutes or moreor less in a soap foam bath, which is prepared with 10 grams soap or more or less for every liter of water. After this treatment. the material is washed in warm water of about degrees centigradc, wrung out and dried. There will thus be obtained a bleached. woolly jute, the touch or gripping of which comes very near to that of wool as regards the fineness or softness.
Example 2: The jute is treated as in Example 1, with the ditl'crcnce, however, that the treatment with hypoehloritc is etl'ccted after that with caustic lye.
Example 3: The treatment of the jute takes place as under 1, but in such a way, that the jute is first treated with caustic lye,

then boiled in soap foam and finally submitted to the action of the hypochlorite.
Example 4: The process is conducted as in. Example 1. without, however, using a bleaching bath of hypochlorite.
Example 5: The jute is treated with a solution of caustic lye of about 36 degrees B. during 5 minutes or longer, then wrungput, washed in water and dried. Afterward it is treated in soap foam during 5 minutes or more, washed again and dried.
In all the examples the washing may be cll'ectcd with acidulated water instead of pure water in order to give also to the material a crashin touch or grip. The treatment in a soap or improved by use of a suitable electric eurreut, as this is already known for the degumming of silk by means of soap foam. Instead of hypochlorite, other bleaching agents may be employed. In an analo ous manner, the caustic lye may be replacet by similarly acting agents. Instead of pressing out the material between presser plates for example, I may use for this purpose a centrifugal. drum or the like.
What I claim is: j
1. The herein described process of render-- ing fibrous material of a vegetable origin woolly, which comprises the subjection of said material to the action of caustic lye, the suitable removal of said lye, and the subjection of said material to the action of a soap t'oam bath to impart said woolly quality. substantially as described.
2. The herein described process of rendering fibrous material of a vegetable origin woolly, which consists in subjecting said material to the action of a bleaching agent, then to the action of caustic lye, removing said lye and subjecting said material to the action of a soap foam bath, substantially as described. I
In witness whcreol l have hereunto signed my name this l-tth day of July 1910, in the presence of two subscribing witnesses.
PETER SCI-IMID.
