The compounds of the formula (1) are as a rule used
on their o~m as active substance.
These compounds are known or are produced by known
methods, such as by bromination or etherification of -
acid esters or of their methylolamide derivatives.
The usual dispersing agents, e.g. those customary
in the dyestuff and textile industries, are suitable as
constituent (b). The followin.g may be mentioned as
examples: lignin sulphonates, aromatic sulphonic acids,
saturated-aliphatic dicarboxylic acids substituted with
longer alkyl radicals, condensation products from aromatic
sulphonic acids and formaldehyde, optionally sulphonated
al.kylphenol-, fatty acid-, fatty amine- or fatty alcohol-
ethylene oxide adducts or ammonium salts thereof, sulphated
substituted benzimidazoles and sulphonated fatty acid
amides. Good results are obtained, in particular, with
substituted benzimidazoles, and especially with ligni.n
sulphonates, with optionally sulphonated ethylene oxide
adducts from alkylphenols, fatty amines, fatty alcohols
or fatty acids, with the ammonium salts of these adducts
and with condensation products from aromatic sulphonic
acids and formaldehyde.

Dispersing agents preferably employed are those which
produce at elevated temperature, e.g. at 180C to 220C,
no yellowing of the treated substrate, or at most a
yellowing that is removable on subsequent washing. In
other words, the dispersing agents either should not
decompose at elevated temperature or should merely form
soluble or volatile decomposition products. The amount of
dispersing agent used is preferably between 1 and 60 per
cent by weight, relative to the halogen compound of the
formula (1). Particularly good results are obtained with
1 to 50, especially with 1 to 20 and in particular with
1 to 4, per cent by weight of dispersing agent, relative
to the halogen compound.
In order to increase storage stability, the aqueous
suspensions or dispersions can also contain a protective
colloid as constituent (c). The protective colloids normally
employed in industry are suitable, such as polyvinyl
alcohol, polyvinylpyrrolidone, methylcellulose, carboxy-
methylcellulose, hydroxyethyl- or hydroxypropylcellulose, -~
gelatine, acid casein, starch paste or polymers of
monomers of the acrylic acid series, such as polyacrylic
acid, e~hyl acrylate copolymers or methyl methacrylate
copolymers. Good results are obtained, in particular,
- 13 -
', ; ............................ '
.
.

1~8~8~6
with polyvinyl alcohol, hydroxyethyl.cellulose and
esp~cially with carboxymethylcellulose.
The aqueous preparations contain as a rule 50 to
700 g/kg, preferably 200 to 700 g/kg, particularly 200
to 500 g/kg, of halogen compound as constituent (a);
0.1 to 300 g/kg, preferably 0.2 to 200 g/kg, especially
5 to 40 g/kg, of dispersing agent as constituent (b);
and 0 to 30 g/kg, preferably 0 to 10 g/kg, of protective
colloid as constituent (c). In each case the amount is :
made up with water to 1 kg.
The constituent (a) is advantageously ground as an
aqueous dispersion in the presence of a dispersing agent :
in such a manner that the particles have a mean diameter
of 1 to 30 ~, preferably 1 to 20~u. Good results are
. .
obtained, in particular, with dispersions having a particle
size of 1 to lO~u, especially 1 to 5 ~u. The particle size
in itself has no effect on the attainable fireproofing
effects, but it does have an effect on the stability of
the dispersions.
The halogen compounds (constituent a)) have only poor :
wettability, so that they are advantageously suspended or
emulsified not just immediately before appli.cation but
- 14 -
. .
.- . ..... . .

1081876
some time previous to this. Pure suspensions, i.e. those
without an ad~ition of dispersing agent, are however
unstable, and ~he constituent (a) rapidly settles out,
an effect rendering impossible an application to fibre
materials. There is therefore according to the invention
always added to the aqueous preparation a dispersing
agent, since this prevents a rapid settling out of the
constituent (a). This sedimentation can, if necessary,
be prevented almost completely by the addition of a
protective colloid. The protective colloids can be incor-
porated into the dispersion either before or after grinding.
Stable dispersions of this kind càn, if required, be con-
verted by drying in a manner known per se, e.g. in a spray
dryer or in a normal paddle dryer, into solid commercial
preparations which can be redispersed at any time.
The grinding of the constituent (a), which is prefer-
ably in the solid state, is performed in conventional
apparatus suitable for such purposes, e.g. in a glass-ball
mill or in a sand mill or in a corundum disc mill.
The invention relates also to a process for the fire-
proofing of synthetic fibre materials consisting of polyester
or polyamide with the aid of a halogen compound of the
- 15 -
. :- . ' ' '
'

~081876
formula (1), in which process these materials are treated
with the aqueous fireproofing composition of the invention
and are subjected to a heat treatment, the procedure
being such that the deposit of the constituen~ (a) after
heat treatment, relative to the fibre material treated,
amounts to 0.5 to 19 per cent by weight.
The fireproofing composition, wllich is in the form of
a concentrated aqueous emulsion, particularly however in
the form of a concentrated aqueous suspension, is to
such an extent diluted with water to a liquor that, with
account being taken of the liquor uptake by the fibre
material to be treated, the required deposit of the
constituent (a) is ensured.
The process according to the invention comprises a
method whereby the fibre material, after treatment with
the aqueous fireproofing composition, is dried and,
optionally, subjected to a heat treatment at elevated
temperature. One suitable method consists in drying the
treated material at a temperature of up to 100C, e.g. at
70 to 100C, and then subjecting it to a heat treatment at
above 100C, e.g. at 100 to 220C, or especially at 150
to 220C, i.e. subjecting it to the thermosol treatment.
The thermosol treatment is preferably performed at
- 16 -

~L081876
175 to 220C and takes as a rule 10 to 200 seconds,
preferably 20 to 100 seconds. Particularly good results
are obt~ined with 10 to 60 seconds.
The procedure according to the invention is preferably
S carried out in such a manner that the deposit of constituent
(a) relative to the treated fibre material, obta;ned by
suitable dilution of the fireproofing composition with
water, is 1 to 12 per cent by weight, depending on the
nature of the fibre material and on the weight per unit
area thereof.
The polyes~er and polyamide fibre materials to which
is imparted according to the invention a fireproof finish,
can be in any desired stage of processing, i.e. they can
be treated in the form of staple or continuous filaments,
or in the form of fabrics or knitwear, dyed or undyed, or
in the form of textiles that have been further processed.
Preferably, however, the material to be treated is textile
fibre material.
The fireproofing composition containing the constituent
(a) can be applied to the fibre material by conventional
methods, e.g. by rinsing, printing or, preferably, by
absorption onto the material, or especially by padding.
. ~ .

.~ : . ... .

~081876
The materials to which the fireproof finish is
preferably imparted are polyester fibre materials. They
are preferably those derived from terephthalic acid, e.g.
poly(ethylene glycol terephthalate) or poly(l,4-cyclo-
hexylenedimethyleneterephthalate). Polyester fibres towhich an effective fireproof finish can be imparted
according to the invention are described, e.g.S in the
US Patent Specifications Nos. 2,465,319 or 2,901~446.
Suitable polyamide fibres are, e.g., those made frorn
poly-2-caprolactam, polyhexylmethylenediamine-adipate or
poly- W-aminoundecanoic acid.
There are obtained according to the invention on
polyester fibre materials and on polyamide fibre materials
permanent fireproofing effects which are retained even
after several washings or dry cleanin~s. The finishes
obtained have moreover the advantage that the handle of the
fireproofed fibre materials is not found to be oily in the way
that it often is when they are treated with known compositions.
Furthermore, the proneness of the fabrics to become soiled
in ~he dry state and in the wet state is not increased.
The fastness to light and to rubbing of dyeings is scarcely
affected.
- 18 -
.
- , , , - . : ~

~081876
A particular advantage of the process according to
the invention is that better fireproofing effects are
obtained with deposited amounts that are smaller than
those required in the case of known processes.
As a result of the present fireproof finishing, the
textile-mechanical properties of the treated fibre
materials are moreover not disadvantageously affected.
By virtue of the small amount deposited, there is -
furthermore scarcely any impairment of, in particular,
the good handle properties of the fabrics treated. The
same applies with regard to the low flexural stifness and
to the high resistance to tearing of the finished fibre
materials. Even printed fabrics can be treated according to
the invention without the quality of the printing in any
way becoming impaired.
The present fireproofing compositions can also be used
simultaneously with dyestuffs or with optical brighteners,
so that dyeing or brightening and fireproofing can be
performed in one process.
Good results are obtained even with the use of small
amounts of dispersing agent, e.g. 0.1 to 3 per cent by
weight relative to the liquor, so that subsequent washing
can, if required, be dispensed with.
