mentioned atomic grouping are compounds o In order to prepare the dispersions to be used the formulae in the invention, the partial esters of higher fatty 0 acids and a glycol may be introduced, advantageously in the molten state in the case of comy pounds which are solid at room temperature, into concentrated solutions or pastes of the above or{ mentioned dispersing agents while rapidly stiract aces ring, advantageously at a temperature above the melting point of the substance to be dispersed.
The dispersions of the present invention may be described as compositions of matter producing a softening eiiect on textiles which compositions of matter comprise an aqueous dispersion of a partial ester of a higher fatty acid and a glycol, said dispersion containing a water-soluble salt of a condensation product of an N-methylolamide of a higher fatty acid with a mercapto-carboxylic acid.
The softening process of the invention may be carried out by impregnating the material at room temperature or a moderately raised temperature with an aqueous liquor containing a small quantity of a dispersion of the kind described above, for example, i to grams per liter, and then Squeezing or centrifuging the material and drying it.
Among the fibrous materials which can be softened by the process of the invention there may be mentioned: Animal fibers such as wool or si cellulosic materials such as cotton, linen, cellulose, paper, and also regenerated cellulose including staple fibers of regenerated cellulose: cel-= lulose acetate artificial silk; synthetic materials produced, for example, by polymerisation or condensation, for example, polyamide fibers; and also leather.
The following examples illustrate the invention. the parts being by weight unless otherwise stated, and the relationship of parts by weight to parts by volume being the same as that of the kilogram to the liter:
Example 1 Chlorinated wool is softened in the following manner:
A bath is prepared which contains, per liter, 1 gram of a mixture of 25 parts of diethylene glycol monostearate. 14 parts of the sodium salt of a. carboxylic acid obtainable by the condensation of stearic acid-N-methylolamide with thioglycollic acid and also 11 parts of the disodium salt of N benzvl- -hepta decyl-benzimid azole disul onic acid. The wool is worked in the bath at a liquor ratio of 1:10 for /4 hour at room temperature and centrifuged and dried. The wool so obtained is distinctly softer than the untreated material.
The dispersion used above is prepared in the following manner:
T68 parts of the sodium salt of the carboxylic acid obtainable by condensing stearic acid-N- methylolamide with thioglycollic acid, and '72 parts of the disodium salt of N-benzyl- -heotadecyl-benzimidazole disulfonic acid are added in portions while stirring to 100 parts by volume of water at 95 C. Then a further 60 parts of the disodium salt of N-benzylr-heotadecvl-benzimidazole disulfonic acid are introduced while stirring, advantageously with the introduction of steam heated to 100 C. In the course of about 30 minutes 300 parts of diethylene-glycol monostearate heated at 90 C. will have been stirred into the homogeneous paste so obtained. The stirring is continued for a short time, then the temperature is allowed to drop to 60 C., and its weight is made u to 1200 parts, and the whole is then allowed to cool while stirring. In order to prepare the treatment bath the concentrated dispersion is boiled with times its weight of water and then further diluted.
The condensation product of stearic acid-N- methylolamide and thioglycollic acid as used above corresponds to the formula ZCHzS-CHz-C and is obtained by condensing one molecular proportion of the methylolamide of commercial stearic acid with A9, molecular proportion of thioglycolllc acid.
A similar efiect can be obtained by using, instead of diethylene glycol monostearate, the cor responding oleic acid ester and in other respects working exactly in the manner described above.
Example 21 Wool is softened in the following manner: A bath is prepared which contains, per liter, 1.25 grams of a stearic acid polyglycol ester obtained by condensing 1 molecular proportion of com mercial stearic acid with 3.8 molecular propor-= tions of ethylene oxide, and also 0.875 gram of the sodium salt of the carboxylic acid obtainable by the condensation of stearic acid-N-methylol=- amide with thioglycollic acid and 0.375 gram of the disodium salt of N-benzyl-;l-heptadecyl-ben-= rimidazole disulfonic acid. The wool is worked in the bath at a liquor ratio of 1:10 for /4 hour at room temperature and centrifuged and dried. The wool so obtained is distinctly softer than the untreated material.
The stearic acid polyglycol ester used above can be obtained by forcing 247.5 parts of ethylene oxide under a, pressure of 6 to 10 atmospheres at l50-l55 C. into 400 parts of commercial stearic acid and 15.1 parts of finely ground sodium acetate.
The dispersion used above may be prepared as follows: 525 parts of the sodium salt of the carboxylic acid obtainable by the condensation of stearlc acid N-methylolamide with thio-glycollic acid and 225 parts of the disodium salt of N- benzyl ,u heptadecyl benzimidazole disulfonic acid are heated at the boil with 3'75 parts of water, while stirring. In this manner a homogeneous paste is obtained. 750 parts of the above described stearic acid polyglycol ester heated to C. are then introduced in small portions in the course of 30 minutes while rapidly stirring. The resulting homogeneous paste is stirred cold and made up to a weight of 3000 parts by the addition of water.
A similar effect can be obtained by using, instead of the above mentioned stearic acid polyglycol ester, the oleic acid polyglycol ester ob= tainable from 1 molecular proportion of oleic acid and 6 molecular proportions of ethylene oxide.
