METHOD 0R PROCESS OF TREATING PAPER FOR TOUGHENlNG AND RENDERING IT IMPERVIOUS.
SIPECIFICIA'JIION'v forming part of Letters Patent No. 740,006, dated September 29, 1903.
Application filed September 13, 1902.
Be it 0 known that I, UHARLEs IGNATIUS GOESsMANN, a citizen of the United States of America, residing in Worcester, in the county of Worcester and State ,of Massachusetts, have invented new and useful Improvements in Processes or Methods of Treating Paper to Toughen and Render it More Impervious, whereby the same is rendered substantially waterproof, grease-proof, &c., and is greatly strengthened,of which the following is a speci-' fication. g
The object of my invention is to provide an improved method or process whereby the absorption of the glutinous material will be rapid and thorough and wherein the absorp tion will not be prevented or retarded by the when the paper or fabric is entirely and continuously immersed in the glutinous material during its passage through the glutin-bath,
and whereby'the absorption or taking up of the glutinous material will be rendered more complete by permitting the air and gases to escape freely instead of being retained or retarded. I accomplish this object by the exposure of the paper or analogous fabric to the glutinous material on one side only during the prim ary application of. the glutinous material. The glutinous bath should be heated to a comparatively high degree of temperature in orderto bring about the best results.
I find that when the; paper is entirely surrounded by the glutinous material the air and gases then emanating from the paper seem to prevent the absorption or taking up of the glutinous material by the paper to the desired extent, and to overcome this objectionable feature I subject the paper to a combined solution and air treatment or exposure, preferably by primarily floating it upon the surface of the glutinous material, so that the air and gases are free to escape from the upper surface of the paper. It is then desirable to apply the glutinous material to the upper surface of the paper and this is most conveniently accomplished by completely immersing the paper prior to its passing to the Serial N0-1Z3|Z12- (No specimens.)
move the surplus glutinous material from the,
surfaces of the paper.
whereby the fabric rests uponthe surface of said solution, the air and gases pass off from the upper surface of the fabric and appear to draw the glutinous material into the fabric from underneath. This insures a more rapid, thorough, and even distribution of the glutinous material throughout the whole sheet. The fabric is now in a condition for further treatment, and after passing the mechanical appliances used to remove the surplus glutinous material from the surfaces it is subjected, preferably by immersion, to a bath of formaldehyde, which renders the glutinous material which has been absorbed by the paper insoluble. In order that this second treatment shall be efficacious to the desired or highest degree, it is necessary that proper saturation with the glutinous mate rial be brought about, and this I am able to do in the manner hereinbefore described. The fabric is next dried and then immersed in a bath of water, preferably hot, after which it is again dried and passed through a calender or subjected to other treatment for the purpose of smoothing, polishing, or otherwise materials will nevertheless take up a cer-v tain amount of water, which enters permanently into its structure and effects a change,
which may be of a chemical or mechanical nature, or both. At all events the water-bath increases the Weight, strength, pliability, and 4 imperviousness of the fabric and cleanses it as a matter of course.
process consisting in freeing the fabric from air and gases and saturating it with the glutinous material by joint exposure to the heated liquid glutinous material and air, then subjecting the material so saturated to a fixing-bath as formaldehyde and then drying.
2. In the process of treating paper to strengthen and render the same more impervious, the step to produce quick and thoroughv absorption consisting in freeing the fabric from air and gases and saturating it with the glutinous material by joint exposure to the glutinous material and air and then applying the glutinous material to the surface first exposed to the air.
3. The process of treating paper for the herein-specified purpose, consisting in prolonged exposure of the paper to a glutinous material and air followed by complete immersion, and then in treating the fabric with formaldehyde.
4. The process of treating paper for the herein-specified purpose, consisting in simultaneous exposure of the fabric to a glutinous material and air, followed by exposure of the surface first exposed to the air to the glutinous material, then in treating the fabric with formaldehyde, then drying, and then treating with water.
5. The process of treating paper to toughen and render it more impervious, consisting in (1st) applying the glutinous material to one side only while exposing the other side to air; (2nd) exposing the opposite side to the glutinous material; (3rd) removing the excess of glutinous material from the surfaces; (4th) subjecting to the'action of formaldehyde; (5th) removing the excess of formaldehyde from the surfaces; (6th) drying; (7th) subjecting to Water and (8th) drying.
(3. In the art of treating paper to strengthen and render it more impervious, the process consisting of subjecting one side only of the sheet to a heated solution of glutinous material whereby the sheet is saturated from the side so exposed while the air and gases escape from the other side, then subjecting the sheet to a fixing material as formaldehyde and then drying.
