Description

ARNO LEI-IMANN, OF RHEYDT, GERMANY.
BLEAGHING SOLUTION.
No Drawing.
To all whom it may concern Be it known that I, ARNo LEHMANN, a citizen of the German Empire, and residing at Rheydt, Prussia, German Empire, have invented certain new and useful Improvements in Bleaching Solutions, of which the following is a full, clear, and exact description.
Textile fibers have hitherto been bleached with solutions of chlorid of lime of 0.1-3 B., which was allowed to act on the material for 1-7 hours. According to the nature of the material to be bleached, a weaker or stronger solution of chlorid of lime and a shorter or longer action thereof is necessary. After the bleaching process, the material is Washed, soured and washed again.
The present invention consists in adding to the bleaching bath malt or malt preparations and especially kromocon. Kromocon is a malt product, containing the constituents of malt, particularly active diastase and other soluble or colloidal albumen substances, in unaltered, natural form. By this addition, the activity of the chlorin in these solutions and also the bleaching action thereof are considerably increased. One is thereby not only in a position to bleach twice as quickly as hitherto but one need also only add one half of the previously employed quantities of chlorid of lime.
The advantage of the invention resides not only in the economy of bleaching agents and the increase of the production but also in the fact that owing to the employment of much less quantities of chlorid of lime, a correspondingly less quantity of salts of lime is left behind in the bleaching material, which is of great value for the further treat- Specification of Letters Patent.

ment of the textile fibers (spinning, dressing and finishing mills) as well as for the cotton wool industry and for the manufacture of powder. The Washing process is also shorter and the danger of corrosion is ess.
It may be stated that the present invention by no means embodies the well-known starch saccharifying or starch dissolving property of the malt or malt preparations (diastafor) which is utilized when taking the dressing or stiffening out of textile fibers. Only the hitherto unknown chlorinaction property of malt and malt preparations is utilized.
Example: 1000 kilos cross-spools bucked in the usual manner are treated with bleaching liquor of chlorid of lime of 05 B., to which are added 700 gr. kromocon mixed in cold water. The bleaching action lasts 2 hours, whereupon the material is washed, soured and washed again. The same quantity formerly required a solution of chlorid of lime of 1 B, and a bleaching action of five hours duration.
I claim as my invention:
1. A bleaching solution containing kromocon.
2. A bleaching solution comprising chlorid of lime and malt.
3. A bleaching solution comprising chlorid of lime and kromocon.
In testimony whereof I aflix my signature in the presence of two witnesses.
ARNO LEHMANN.
