STATES FRITZ ARLED TER, on PERLEN, SWITZERLAND;
MANUFACTURE OF RESINOUS SOAP.
SPECIFICATION forming part of Letters Patent No. 627,287, dated uii 20, 1899.
Application filed December 211 1897. Serial No. 662 889. (No specimens.) i
To all whom it may concern: I
Be it known that I, FRITZ ARLEDTER, en gineer, a citizen of Switzerland, and a resident of Per1en,near Lucerne, Switzerland, have invented certain new and useful Improvements in Manufacture of Resinous Soap, of which the following is a specification.
This invention has been patented to me in Norway under date of November 22, 1897, and in Germany under date of November 18, 1897, No. 95,416.
My invention relates to the manufacture of resinous soap containing unsaponaceous resin and which is particularly adapted for use as paper-size in the manufacture of paper.
According to my invention I boil the mass under pressure While continually stirring the same, the contents being thereby substantially converted into liberated resinthat is to say, for the boiling of the soap according to my invention only seven to ten per cent. of alkali is necessary as against ten to fifteen per cent. by the methods hitherto known. The chemically-free or so-called liberated resin may amount to forty-five per cent. of the resinous soap as against twenty-five per cent, which has hitherto been the maximum. Acting on the theory of Dr. Wiirsterviz., that only liberated resin sizes paperI have succeeded in sizing paper with one and a half to two per cent.- of resin-that is to say, one and a half to two kilograms of resin to one hundred kilograms of paper. The main feature of my invention consists, therefore, in
the large proportion of liberated resin and in the microscopically-fine distribution of this resin, wherebya considerable saving over the sizingmethods hitherto known is effected.
Among the advantages of my method of manufacture may be specially mentioned: Oonsiderably shorter duration of the boiling. The quantity of liberated resin may be raised tofifty per cent. without causing inconvenience by the dissolution of such resinous soap, such as deposit of undissolved resin, obstruction of the piping, and of the papermachine. By steady boiling uniform sizing is obtained, and I am enabled to size paper with one and a half to two per cent. of resin. A condsideralole saving is therefore obtained over the hitherto-known methods.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The herein-described method of producing aresinous soap containing unsaponaceous resin serviceable in the manufacture of paper as paper-size consisting in boiling under great pressure resin and a quantity of alkali not sufficient for the complete saponification of the resin, substantially as described.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two Witnesses, this 23d day of November, 1897.
