A UNITED STATES ATENT OFFICE.
ARTHUR FIELDING, OF SALFQRD, ENGLAND.
. MANUFACTURE OF VISCOSE.
SPECIFICATION formingpart of Letters Patent No. 708,760, dated September 9, 1902.
Application filed November 5, 1901.
T0 00% whom it may concern: ,7
Be it known that I, ARTHUR FIELDING, man ufacturing chemist, a subject of the King of Great Britain, residing at George street, Sal- 'ford, in the county of Lancaster, England,
have invented certain new and useful Improvements in or Relating to the Manufacture of Viscose, (Cellulose Sulfocarbonate,) of which the following is a specification.
My invention relates to improvements in or relating to the manufacture of viscose (cellulose sulfocarbonate) prepared according to the specification of United States Letters Patent granted to Cross, Bevan, and Beadle, N 0. 520,770, dated June 5, 18,94; and the object of my invention is to manufacture a colorless or approximately colorless viscose.
At the present time viscose is employed in the manufactureof certain kinds or qualities of paper; but its application has been limited to a great extent by its com arativel da shadewmai hgi s in the manufacture of white paper or certain light and delicate shades of paper.
According to my invention I make a soluticu of bisulfite of sg da or other suitable bisulfitesf'andTlnrfi a qeftainproportion of the solution with the'viscose'in'or- 'erto neutrali'ze its color and malii't'suitable fo themanufacture of White paper from wood-pulp or fibrous pulp from other suitable material.
It is obvious that the bisulfite of soda or other bisulfite in solution may be added to any mixture of fibrous pulp, &o., wiurviscose g table is lifiitetsn hashisulfitiifiihindsa,
Serial No. 81,250. (No specimens.)
for the purpose named. After treatment solution.) These quantities are suitable for adding I9 1 beater containing the equivalent of six huhdredflunds of dry pulp. The bisulfite may be added to the fibrous pulp before or after the viscose has been put into the beater insteadof beingmixeibefomhand. Instead'of bisulfite of soda any other may be used or a mixtuile gf bgthi What I claim as my ihvention, and desire to secure by LettersPatent of the United States, is-
The herein-described process consisting of 55 the admixturepf a suitablebisulfitewith vis coselcell'ulose sulfocarbjonate) and the incorporatipn of th ixture with'fibrous pulp in the maniifa'tii o f pafff'and subsequent drying and steaming to complete the decolcrizationand fixation of the viscose- In Witness whereof I have hereunto set my hand in presence of two witnesses.
ARTHUR FIELDING.
