Description

The invention relates to a composition for textile treatment, in particular a composition to improve the grip and rewettability properties is determined by textiles.

The washing of soiled textiles is nowadays done with the help of synthetic detergents generally anionic type in more satisfactory Wines made. Ho get cleaned textiles however, often a rough handle, which in particular; annoying with textiles worn directly on the skin itit. To overcome this disadvantage, the White detergent introduced, which was added to the rinse water and the textiles wj eder their original Give softness. Most of these compounds are quaternary ammonium derivatives, in particular

Chlorides. Although the softening effect is beneficial is, it was found that at the same time a reduction in the rewettability of the with it treated tissue occurs: the resulting reinforcement of the hydrophobic character causes yellowing and the fabrics become dirty with them, rendering them unusable over time. More complicated Nitrogen derivatives such as imidazoline derivatives have also been used to treat textiles suggested; however, the products do not give good results than the quaternary ammonium derivatives, both in terms of the plasticizing effect and in terms of rewettability.

The invention relates to a composition which improves the rewettability with preservation allows a satisfactory softening effect. The composition is different Fabric types based on artificial or natural fibers can be used, but is particularly suitable for Textiles made from natural materials such as cotton alone or in a mixture with other fibers are recommended.

in which R, R 'and R. have the above meaning and B represents an acid.

The anions A include, for example, the halide ions, sulfate ions, ethyl sulfate ions or methyl sulfate ions; B represents an acid such as hydrochloric acid, sulfuric acid, ethyl or methyl sulfuric acid.

The imidazolinium derivatives which can be used according to the invention include, for example, the 2-stearyl-l-stearyl- (or 1-lauryl- or 1-oleyl-) amidoethyl-1-methylinddazcuinium chloride and methyl sulfate, the 2-01eyl-lstearyl- (or 1-oleyl-) -amidoethyl-1-methyl-imidazoline chloride or methyl sulfate, 2-lauryl-1-stearyl- (or 1-lauryl) -amidoethyl-1-methyl-imidazolirdnm-chloride and methyl sulfate, the 2-stearyl-1-stearyl- (or 1-oleyl- or 1-lauryl) -amidoethyl-1-ethyl-imidazolinium-ethyl sulfate or the 2-oleyl-1-stearyl- (or 1-lauryl- or 1-oleyl) -amidoethyl-1-ethyl-imidazolinium-αfchylsulfat

as well as 2-lauryl-1-stearyl- (or 1-oleyl- or 1-lauryl) - -amidoethyl-1-ethyl-imidazolinium ethyl sulfate. A preferred compound consists of the 1-methyl-imidnzoHniLiTi-methyl sulfate derivative hydrogenated Talc fatty acids (i.e. a mixture of fatty acids in which stearic acid predominates), the as 2-stearyl-1-stearyl-amidoa'thyl-1-methyl-imidazolinium methyl sulfate to designate · «is.

The salt of diamidoamine is the second component of the composition according to the invention " as a preferred nelspiel is the methyl bis, (ät.hyleiii5tearnmid) -amin-met.hyl: to name juirnt. Other inventions.gemril.? usable compounds of these Class are the methyl sulfates and chlorides of methyl-bis-ethylene-oleylamide (or laurylamide) - -amine, the methyl sulfates of Methyläthylenstearamidä'thylen-oleylamid- (or Ethylene-stearamide-ethylene-laurylamide- or ethylene-oleylamide-ethylene-lauryl- ' amide) - -amine, which correspond to the methyl methyl sulfates Ethyl-ethylsulfate, the methyl-bis-

Ethylene stearamide amine ethyl sulfate.

The compositions according to the invention contain 10-40 ow, -% of the diamidone amine salt, ^ preferably .. 1 ^r > - 25% by weight. It was found ¹ that if the content is below 10%, the degree of rewettability is practically not improved in comparison with the imidazolinium salt alone. At contents above ^ 0 % , the diamidoamine has a negative effect on the softening effect of the imidazolinium salt, and the treated fabrics no longer have a satisfactory feel.

509881/1074

The compounds are produced in a known manner. For example, the imidazolinium salts are obtained by condensation of fatty acids with polyamines, which is then followed by cyclization and quaternization. The condensation and cyclization require several hours of heating at elevated temperatures, for example 12 hours at 225 ⁰ C. The quaternization of Amidoimidazolins thus obtainable is preferably carried out in an alcoholic medium under cooling, keeping the temperature 90 ° does not exceed; the reaction is virtually instantaneous. To produce the diamidoamine salt, for example, the amidoimidazoline can be hydrolyzed in an alkaline medium, whereupon it is separated off by decanting; the amidoamine thus obtained is then subjected to an alkylation reaction to obtain the desired salt.

The preferred method for preparing the composition of the invention is based on the direct preparation of the mixture of imidazolinium and diamidoamine salt. Since the preparation of the imidazolinium salt in the cyclization step, as mentioned above, requires rather long heating at relatively high temperatures, it has been found that the use of less high temperatures for shorter reaction times only leads to partial cyclization and thus allows the desired mixture to be prepared directly . The shorter the reaction time and the lower the temperature increase, the higher the percentage of the amidoamine obtained. For example, allows only for 8 hours heating at 200 ⁰ C the production of a mixture of 40% diamido
