Description

DLUQQL BAHON F mums a I'IULHIS,
ITED STATES PATENT OFFIQE.
ANDREW POULSON, OF WIDNES, ENGLAND.
BLEACHING, SCOURING, AND DECORTICATING FABRICS 0R FIBROUS MATTER.
No Drawing.
To all whom it may concern:
Be it known that 1, ANDREW POULsON, a subject of the King of Great Britain, residing at Springfield Villa, Hough Green,
VVidnes, England, have invented certain new and useful Improvements in Bleaching,
N i i scouring, and Decorticating Fabrics or Fi- F brous Matter, of which the following is a specification.
This invention relates to an improved process and composition for bleaching textile fabrics or other material, such as waste paper, straw board, or the like, and for scouring or decorticating wool or other fibrous material and is designed to provide a more economical process than those at present obtaining for such purposes. The present usual process of bleaching consists in immersing the material to be bleached in a tank or the like containing a solution of sodium hypochlorite, or bleaching powder,
together with some suitable acid the solution being kept at boiling point for from eight to twelve hours, after which the mate rial is removed and washed, in some cases with a solution of weak acid or soap and water.
According to this invention the material to be bleached is boiled in a tank or the like receptacle for from one to two hours, in a solution of a special powder, consisting of about equal parts of ordinary commercial n Sada.aniotsediunbicarbonate, the solution being made up approximately in the proportions of one ounce of such powder per gallon of water. After the material has been boiled for the period mentioned and while the solution is still boiling a small portion, say, about three per cent. of a solution of sodium hypochlorite is addedTo the solution in tie receptacle, and the combined solution boiled for another one to two hours. The bleaching operation is then completed and the material may be removed and dried or treated in any suitable manner. If desired the sodium hypochlorite instead of %\being made up as a separate solution, may 5* be incorporated with the washing soda and sodium bicarbonate in the first instance.
Such a process results in a considerable economy in the time requisite for eifecting the bleaching operation, and is found to be Specification of Letters Patent.
Application filed February 12, 1917.
Patented Jan. 29, 1918.
Serial No. 148,291.
in no wise detrimental to the fibrous character of the material being treated. Further, the one operation of boiling serves to Wash as well as bleach the fabric or other material, and the additional expense necessitated by having separate washing baths, as in the usual process, is avoided. The process is found to be quite effective for bleaching ordinary brown paper, for removing printers ink from old newspapers, and for the ordinary bleaching requirements of the textile industries.
The powder consisting of equal parts of commercial washing soda or soda ash and of sodium bicarbonate may be used in weak solution for ordinary washing purposes or as a cleanser for paint or varnish. By making the powder up into a very strong solution, flax, hemp, jute and other fibers may be decorticated or retted in. a few hours, thus securing a considerable saving over the present methods of dealing with such fibrous material which require them to be left for a considerable time to rot, thus necessarily weakening the fibers.
The powder is also of great value as a purifier and preservative for fish, hams and other foods, which have become high or 80 rancid, while as a meat preservative in hot weather it has been foundsuperior to borax or boracic acid. For scouring raw Wool in bulk and for cleaning it of its impurities, a solution of the powder is found very efi'ective, the wool besides being cleaned and scoured having all the fats removed and rendered down.
I claim- The improved process for bleaching tex- 90 tile fabric or other material, which consists in boiling the material to be bleached in a solution of commercialrwashing soda and sodium bicarbonate so--- as to soften the gummy material therein, and subsequently 95 addinga small quantity of sodium hypo; chl gri tertothe solution contaminant fabric. and a continuation of the boiling.
In testimony whereof I aifix my signature .in presence of two witnesses.
