Definitions
- This invention relates to a process for anticrease finishing textile fabrics consisting of cellulose fibers and mixed fabrics containing cellulose fibers. More particularly, t relates to an anticrease finish for these fabrics with d1- methylol uron and a lower dialkyl ether thereof.
- the fabrics are 1mpregnated with solutions of the N-methylol compounds that further contain an acid donator, such as ammonium chloride, subsequently dried and cured at an elevated temperature for a certain period of time, e.g., 3 minutes at 150 C.
- an acid donator such as ammonium chloride
- the textiles impregnated with the finishing agents in an acidic liquor are, immediately after their impregnation batched up and allowed to react whilst still wet.
- a so-called wet cross-linking crosslinking under wet conditions
- this crosslinking process under wet conditions is termed wet crosslinking process.
- the moisture content of the textile material after the incomplete intermediate drying prior to storage is of decisive influence on the obtainable effects.
- the wet-crease angles are only little dependent on the residual moisture, the dry-crease angles increases according as residual moisture decreases, which is accompanied by a diminution of the tensile strength.
- High wet-crease angles and adequate dry-crease angles with little losses in tensile strength are obtained when maintaining, according to the present invention, a residual moisture content of between 5 and 25 preferably 8 to 15%.
- mineral acids may be employed, such as hydrochloric acid, sulfuric acid and phosphoric acid or also organic acids, such as formic acid or trichloroacetic acid.
- Drying of the impregnated material so as to reach the desired residual moisture content may be done at room temperature (about 20 C.) but higher temperatures, e.g. 100 C., may also be used.
- the most advantageous storage time for the moist textiles depends on the pH-value of the impregnation liquor and the temperature during storage; the storage time may vary from 1 to 24 hours.
- the dimethylol uron utilizable under the present invention is, for example, obtained by saponification of the dimethylol uron dialkyl ethers at a pH-value of 3-2 and temperatures of preferably 5090 C.
- Dimethylol uron dialkyl ethers are prepared in the known manner by short-term heating of urea with formaldehyde under certain conditions and by subsequent etherification of the dried reaction mixture with an alcohol, in the presence of an acid.
- the pH-conditions (pH 3) of the finishing process under the present invention are vastly in accord with those of the above-mentioned saponification process (pH 32). Therefore, on principle, the ethers of the dimethylol uron may also be employed in place of the dimethylol uron itself, because they are saponified in the prepared liquor. Employing, however, dimethylol uron ether instead of dimethylol uron, somewhat poorer effects are always observed, which might be due to an incomplete saponification.
- EXAMPLE 1 A bleached and mercerized fabric consisting of a cotton poplin mixed fabric was impregnated on the padding machine with an aqueous solution containing 150 grams/ liter dimethylol uron (in the form of a 60% solution), and 17 grams/liter hydrochloric acid (37% by weight), the pick-up of liquor being based on the weight of the air-dried fabric. Subsequently, the impregnated fabric was dried at a temperature of about so as to reach a residual moisture content of 10%, batched free from creases and wrapped in a plastic sheet, stored for 20 hours, at 20. At the end of this period, the fabric was rinsed with water, treated with a solution of 2 grams/liter sodium carbonate at 50, then rinsed again with water, and finally dried at 70.
- a bleached and mercerized fabric consisting of a cotton poplin mixed fabric was impregnated on a padding machine with an aqueous solution that contained, 176 grams/ liter dimethylol uron dimethyl ether, and the pH-value of which had been adjusted to 1.3 with hydrochloric acid; the squeezing effect was 74% based on the weight of the air dried fabric. Subsequently, the fabric was dried. at 100 to give a residual moisture content of 8%, batched free from creases, and wrapped in a plastic sheet, stored for 16 hours at 20. It was further treated as described in Example 1.
- a cotton fabric consisting of a cotton poplin mixed fabric was impregnated on the padding machine with a finishing liquor containing 150 grams/liter dimethylol uron in the form of a solution and 40 cc./liter 12 N-sulfuric acid.
- the impregnated fabric was batched up immediately afterwards, and wrapped in a plastic sheet, stored for 3 hours at 20. These conditions correspond to the wet cross-linking process.
- a process for imparting an anticrease finish to a cellulose fiber textile which comprises impregnating said textile with a solution of dimethylol uron at a pH of below 3, drying the impregnated textile to a residual moisture content of between 5 and 25% by weight, based on the weight of the completely dried fabric, then wrapping the thusly dried impregnated textile in a plastic sheet, storing the wrapped fabric for between 1 and 24 hours, subsequently neutralizing excess acid in said fabric and rinsing and drying the thusly treated fabric.
