It is known that textiles whicll have been washed, es-
pecially in an automatic washer~ and particularly thoqe
made from cellulose fibers, are in a disagreeable har-
dened state after drying. This undesirably hardened feel
can be overcome by treating the textiles aftcr washing
in a rinsing bath with cationic subqtance~ which contain
at least two long-chain aliphatic radicals in the mole-
cule. Especially the dialkyl-dimethylammonium salts dis-
persible in water have proved in the practice to be
suitable for this application. However, on overdosage,
these product~ have the disadvantage of making the treated
fabric too hydrophobic, thus retarding rewetting. More-
over, it is very difficult to combine ~uch long-chain
dialkyl-dimethylammonium salts with short-chain dialkyl-
quats, for example in order to prepare fabric softener
formulations having a bactericidal activity. Furthermore,
these dispersions have the disadvantage of a milky, turbid
appearance, while nowadays fabric softeners in the form of
transparent aqueou~ solutions are in demand.
It has now been found that these disadvantages are
overcome by combining the quaternary ammonium compounds
used as fabric softeners with a fatty acid alkylol-
amidoxethylate. Subject of the invention are therefore
fabric softeners in the form of an agueous solution or
dispersion which contain from 3 to 15, preferably 3 to 8,
weight % of one or more compounds of the formulae I to IV

in which R4 i~ alXyl having from 8 to 30, preferably 10

and optionally from 3 to 5 weight % of a bactericidal
quaternary ammonium compound, and further usual auxi-
liaries and additives.
This combination of the compounds I to V impart~ an
pleasant and soft feel to any textile material, es-
pecially those made from natural or regenerated cellu-
lose, wool, cellulose acetate, cellulose triacetate,
polyamide, polyacrylonitrile, polyesters or polypropylene.
Especially advantageous is its use for the after-treat-
ment of terry fabrics and underwear. The fabric softeners
of the invention are prepared by simply mixing or dis-
., .

per~ing the individual components in water. They may con-
tain one compound each of the formula I to IV, or a mix-
ture of two or more compounds of these formulae within
the ranges a~ indicated. In the case of a mixture of two
or more compo~nd~ of the formulae I to IV, the mixing
ratio thereof with one another is not at all critical
and may have any value.
In addition to the compounds of the formulae I to V,
the softeners of the invention may contain from 3 to 5
weight % of a bactericidal compound, especially selected
from the group of compounds of the following formulae

R7/ R2
in which R1, R2 and A are as defined above and R7 is an
aliphatic radical having from 6 to 12, preferably 10,
carbon atoms.
The fabric softeners of the invention may also con-
tain further substances and auxiliaries which are either
mixed already with the concentrate of the fabric softener
or are ad~ed ~epa~ate~y~ to the ready-to-use , dilute
composition. These are substances or auxiliaries which
are conventionally used in softening compositions; they
-

include, for example, cationic and nonionic surface-
active substances, electrolytes, neutralizing a~ents,
organic complexing agent~, optical brighteners and ~olu-
bilizers, as well as dye~tuffs and perfumes. Additives
of this kind serve, for example, to further influence the
feel of the fabric or other properties of the textile
goods to be treated, or the ~djustment of the visco~ity
or pH or further promote the stability of the solution~
at low temperatures.
The fabric softeners are applied as usual, that i8
they are added to the last rinsing water after the
washing operations are complete. The textiles so treated
are subsequently dried.
The above fabric softeners are absolutely trans-
parent and have the advantage of providing a considerablyimproved rewettability of cotton as compared to commer-
cial products. It is furthermore surprising to ob~erve
that even those compounds of the formulae I to IV have
~ good softening effect in combination with a compound
of the formula V which contain more than 50 % of alkyl
groups containing only 12 carbon atoms, although it is
known that such compounds per se have only a moderate
~oftening effect as compared to di-tallow fatty alkyl-
dimethylammonium chloride. The fatty acid alkylolamidox-
ethylates per se have no softening activity.
The following example~ describe some softeners ofthe invention; percentages being by weight in all cases.
All these softeners are prepared by simply mixing aqueous
solutions of the individual components with agitation
30 at low temperature.

These fabric ~ofteners were tested according to
German Indu4trial Standard DIN 53924 with respect to
their influence on the rewettability. Smooth cotton and
polyester fabrics (satin blouse cloth) were treated with
the mixture of the invention. A commercial softener
~E~ample 7) wa~ used for a compari~on. According to this
test method, the results listed in the following Tables
were obtained for the mixtures of Examples 1 to 7. The
