• Bleached cretonne fabric of cotton is impreg nated with a cuprammonium solution containing 15 grams of copper and 5 grams of sodium hydroxide per liter and after a short action time of 15 seconds is precipitated by sulfuric acid of 2 B. at 15 C. coincidentally with the acid precipitation the elimination from the fiber of the copper is assured. After calendering the finished fabric exhibits a supple elastic feel resembling linen.
• Mercerized cotton yarn is briefly treated during 15 seconds with a solution of cuprammonium containing 12 grams of copper and 8 grams of potassium hydroxide per liter and immediately thereafter washed with water at 18 C. Elimination of copper is accomplished in the usual way with dilute acid. The finished yarn resembles linen yarn.
• Pre-treated calico fabric is passed for a short time through a cuprammonium solution containing 10 grams of copper and 3 grams of sodium hydroxide per liter, after an air passage of 40 seconds, followed by precipitation by the aid of dilute caustic soda at 4 B. at 20 C. Elimination of copper after the latter treatment is effected in the usual manner. Theresult of the ennobling effect is similar to that in Example 1 except that an increased stiffness is noted.
• Cuprammonium solution comprising 13 grams of copper and 10 grams of sodium hydroxide per liter is caused to act upon a heavy cotton fabric for 20 seconds at 10 0. Immediately thereafter the swollen unwashed fabric is mercerized in the mercerizing machine with the use of concentrated soda lye, followed by-elimination of copper by acidulation and washing. For finishing intense calendering and mangling are applied with the result that the fabric assumes the characteristics of heavy linens.
• a resist-printed fabric is treated according to the procedure in Example 4.
• the fabric exhibits patterning of damask-like nature; the reserve portions of the fabric show unaltered properties, and thus contrast with the other parts that have been subjected to the action of cuprammonium solution.

After drying there results a lustrous stifi fiber of agglutinated ramie fibers or filaments.

• Steps in the method of producing permanent finish efiects on vegetable cellulose material consist in preparing a cuprammonium solution containing a free alkali metal hydroxide in which the percentage of free alkali does not exceed 1.5% of the weight of the solution, and subjecting the vegetable cellulose material to said solution.
