Definitions
- Patented May 21, 1935 2 002 105 UNITED STATES PATENT OFFICE PROCESS FOR TREATING VEGETABLE mans Albert 'Bodmer and Ernst Weiss, Wattwll,
- Valuable efiects can be produced on vegetable that the proc i greatly p v r 1Ihe fibers by the action of cuprammonium solution viewpoint f e n my n P fi and caustic alkali solution in accordance with the
- the novel m od f h pr n invention is 15 procedure of applicants copending application useful for all kinds of vegetable fibrous structures which has now matmed into Patent #1,896,620 as Well as 10058 fi Vegetable fibrous matedated February '7, 1933.
- That process r t upon rial may be submitted to treatment inthe bleached the production of a swelling effect initially prostate or in any other pre-treated condition as well go pokerd in a certain manner upon the fibers with as mercerized- Fibrous Structures consisting of a following treatment thereof whereby alteration Vegetable fibers of Various O s 0 mi d w of the properties of the fibrous structure is proother natural or artificial fibers, can be ennobled cuted. It has now been discovered in accordinthis manner- By the aid of Suitable apparatus ance with thi inv ti th t very'sman mm.
- the same*process can be carried out so that by tion of free lk li sharp1yihoreases t swelling the action of the swelling material the fibrous 25 of the material and cessation of swelling structureis not altered throughout, but the swell- (Entquellung) may be arranged so t the ing occurs only on one side and superficially. nobling effect on t fiber is considerably The action not only of the cuprammonium but proved, 1 ha found also in accordance with also of the alkali lye may be carried on while the thi i ti t t t addition and m fibers are ineither loose or tensioned condition.
- caustic soda is employed as alkali alslble employ dn'ect application by Printing 40 though caustic potash and the hydroxides of the spraying or smattering with or without the use 40 of thickeners as well as to use resist printing accompanied by subsequent dipping in to the swell-
- the cuprammonium solution thus made is ca mg agent
- durable patterns can be pable by itself of ennobhng vegetable fibers and produced by subjecting a previously mercenzed to produce efiects of the kind described in the f b to 1 81 h t d th copendin a lication Ser No 321505 0 P t no o pressmg an en su Jec mg 45 g pp i n w a it to the action of swelling agents in accordance out No.
- solutions of this kind are not capable be obtained with water, dilute acid or dilute alof producing the ennobling efiects above referred kali lye, whereby generally the efiect produced by to because they cause a noticeable solvent action the dilute alkali is stifier, that with dilute acid on the cellulose subjected to swelling so that the 55 rare earth metals are also useful.
- 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.
- Card sliver made of ramie fibers is impregnated with a, solution of cuprammonium containing .14 grams of copper and 4 grams of sodium hydroxide per liter and after a reaction time of 30 seconds then subjected to mercerizing with. soda lye and is de-coppered in the usual manner. After drying there results a lustrous stifi fiber of agglutinated ramie fibers or filaments.
- a method of producing permanent finish effects on vegetable cellulose material which comprises preparing a bath containing cuprammonium and a free alkali metal hydroxide in which the percentage of free alkali does not exceed 1.5%
- 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.
