Definitions
- the proportions in which the above mentioned ammonium salts are to be added per litre of liquor may vary within wide limits. An addition of about 0.5 to about 2 grams per litre of liquor generally suffices. For reasons of economy a proportion within the range of about 0.6 to 1 gram may be used, although proportions smaller'or larger than those mentioned above, for example, 0.3 or 5.0 grams, may be added.
- the proportions of the sulphonic acid and/or carboxylic acid, or the salts thereof, containing an aliphatic radical of high molecular Weight interrupted by a carboxylic acid amide or carboxylic acid ester group may also vary within wide limits. It is possible to add quantities equal to, inferior to or larger than the quantity of ammonium salt used. In many cases it is sufiicient to use about one fourth of the amount of ammonium salt. Normally, quantities will be used amounting to one fourth up to the equal amount by weightof ammonium salt used. In
- tities of the surface-active substances claimed Somemethyl-amino acetic acid, hydroxymethaneor hydroxytimes, it is also suflicient to add inferior quantities; in some cases the amount can be reduced to about 3& of the quantity of ammonia salt used.
- the additions customarily used for adjusting the pH-value for example, hydrochloric acid, formic acid, acetic acid, oxalic acid, phosphoric acid, nitric acid, bisulphates such as sodium bi-' sulfate, acid ortho-phosphates, pyrophosphates, acid polymeric phosphates or mixtures of these acid compounds, and the like.
- reaction products as are obtained for instance by causing fatty acids ofhigh molecular Weight i.e. such containing more than 8 carbon atoms on amino-sulphonic or aminocarboxylic acids of low molecular weight or on protein decomposition produts.
- fatty acids ofhigh molecular Weight i.e. such containing more than 8 carbon atoms on amino-sulphonic or aminocarboxylic acids of low molecular weight or on protein decomposition produts.
- condensation products of the salts from the above-mentionedfatty acids and halogen-sulphonic acids or halogen-carboxylic acids can also be obtained by causing fatty acid derivatives to act upon aliphatic hydroxycarboxylic acids of low molecular weight.
- Such 'compounds are disclosed, for instance, by Schwartz-Perry Surface Active Agents, 1949, pages 34-39, 94-97 and 102l03.
- reaction products of fatty acids particularly in the form of their chlorides, containing more than 8 carbon atoms, especial- 1y those containing 12-18 carbon atoms, as, for instance, lauric acid, myristic acid, palmitic acid, stearic acid, or oleic acid with amino acetic acid, taurine, methyltaurine,
- ethane-sulfonic acid tartaric'acid and the like, for instance lauryl-methyl-tauride, oleyl-methyl-tauride, myristyland palmityl-tauride, stearyl tauride, stearoxy-methane and stearoxy-ethane-sulphonic acid, laurylsarcoside,'
- stearylsarcoside stearate of tartaric acid obtained by reaction of stearic acid chloride in dry pyridine on tartaric acid, etc.
- the invention also includes a solid composition suitable for diminishing the formation of chlorine dioxide in' group or a salt of such acid of high molecular weight:
- composition is stable, and provides a mixture of the ingredients in the appropriate relative proportions
- a salt of an acidof an oxide of nitrogen advantageously sodium nitrate, may also be incorporated in the above composition.
- Such compositions are very stable.
- Example 5 A fabric of staple fibers of viscose was treated for 40 minutes at 75 C. at a goods-to-liquor ratio of 1:20 with a solution containing, per liter, 1 gram of sodium chlorite, 2 grams of ammonium nitrate, 5 grams of ammonium sulphate and 0.2 gram of oleyl-methyl-tauride and having a pH value of 3.5, adjusted by addition of mono-sodium phosphate and then rinsed.
- the material thus bleached had a whiteness of 79.8 percent.
- the consumption of sodium chlorite was not more than 0.18 percent. No liberation of chlorine dioxide occurred.
- the same quantity of ammonium chloride or ammonium acetate may be used.
- Example 6 A fabric of staple fibers of viscose was treated for 40 minutes at 75 C, at a goods-to-liquor ratio of 1:20 with a solution containing, per liter, 1 gram of sodium chlorite, 0.3 gram of ammonium chloride and 3 grams of lauryl-methyltauride and having a pH value of 3.5 adjusted by addition of formic acid, and then rinsed.
- the material thus bleached had a whiteness of 80.2 percent.
- the consumption of sodium chloride did not exceed 0.21 percent. No chlorine dioxide escaped during the bleaching process.
- the same quantity of ammonium sulphate, ammonium chlorate or ammonium acetate may be used.
- Example 7 Knit goods of staple fibers of cellulose acetate were treated for 20 minutes at 70 C., at a goods-to-liquor ratio of 1:25, with a solution containing per liter 1.5 grams of calcium chlorite, 0.4 gram of ammonium chloride and 2 grams of lauric acid methyl tauride, as well as 1 gram of stearic acid sarcoside.
- the pH value of ,the bleaching bath was adjusted to 3.0 by means of a (mixture consisting of sodium acetate and hydrochloric acid in a proportion of 1:1.
- Example 8 Yellowed yarn of polyamide fibers consisting of hexamethylene diarnine and adipic acid were treated for 1 7
- Example 9 A fabricof polyester fibers from polyethylene glycol terephthalate was treated in a goods-to liquor ratio of 1:30 with a solution containing per liter 2 grams of sodium chlorite, 3 grams of ammonium phosphate, 2 grams of a condensation product of fatty acids of tallow and hydrolized protein and 1 gram of acid sodium hexa- -methaphosphate and adjusted to a pH value of 2 .5 by
