Claim 1
Independent Claim
144 words
A PROCESS FOR SETTING TEXTILE MATERIAL FORMED OF ANIMAL HAIR WHICH COMPRISES: ARRANGING SAID TEXTILE MATERIAL IN A PREDETERMINED CONFIGURATION AND WHILE MAINTAINING SAID CONFIGURATION, FIRST TREATING THE ANIMAL HAIR GOODS WITH AN AQUEOUS SOLUTION CONSISTING ESSENTIALLY OF AT LEAST ON OF ALKALINE SUBSTANCES SELECTED FROM THE GROUP CONSISTING OF HYDROXIDE, CARBONATE AND BICARBONATE OF SODIUM, POTASSIUM AND AMMONIUM, AND LOWER ALKANOL AMINES IN A CONCENTRATION OF THE RANGE FROM 0.1 TO 5% BY WEIGHT, SAID SOLUTION BEING ADJUSTED TO A PH OF THE RANGE FROM 9.0 TO 10.5, IN THE FIRST STAGE TREATMENT; AND THEN TREATING THE THUS TREATED ANIMAL HAIR GOODS WITH A AQUEOUS SOLUTION CONSISTING ESSENTIALLY OF A WATER SOLUBLE SALT WITH AN ORGANIC OR CARBOXYLIC ACID OF A HEAVY METAL SELECTED FROM THE GROUP CONSISTING OF CALCIUM, ALUMINUM, TIN, LANTHANIUM AND ZIRCONIUM FORMING A COLORLESS COMPLEX WITH SAID ANIMAL HAIR.
