    Abstract: Glass fibres are dyed or printed with pigments using as a binder a film-forming polymer which becomes cross-linked under the influence of a proton-acceptor and using an amino-silane or a hydrocarbon wax as an agent having hydrophobic action to promote adhesion between the binder and the glass surface, the process being carried out in the presence of a proton-acceptor, and the treated fibres being finally dried and heated. The polymers are those having groups, for example amino or hydroxy groups, which by means of proton acceptors can enter into covalent bonds with themselves or other groups. The preferred polymers are copolymers bearing hydrocarbon radicals as side chains in which a halogen atom and a hydroxyl group are attached to two adjacent carbon atoms, particularly a polymer obtained by co-polymerising 2-hydroxy-3-chloropropyl acrylate with other monomers. The proton-acceptor may be an alkali metal hydroxide, carbonate or bicarbonate, amonia or an organic amine; it may be provided as the alkali present in the glass. The glass fibres may be treated as such, mixed with other fibres or in the form of fabric. In the treatment, the various components can be applied separately or in combination. Examples illustrate the use of copper phthalocyanine, azo dyes and carbon black as the pigments.

    Abstract: Dyeings with reactive dyes on cellulose fiber materials are after-treated with an aqueous solution of a condensate which is obtainable by reacting (a) bisbenzylpiperzine with (b) ethylene chloride, an epihalohydrin, propylene chloride, 1,3-dichloro-2-hydroxypropane, bisepoxybutane or 1,4-dichlorobutane or a mixture of these, in a molar ratio of from 1:0.5 to 1:1.1, or by reacting (c) piperazine, bis-1,4-aminopropylpiperazine, 1-aminoethylpiperazine, 2-hydroxyethylpiperazine or 1-methylpiperazine, or a mixture of these, with a compound according to (b) in a molar ratio of from 1:0.5 to 1:1.1 and benzylating the condensate, the benzylation being carried out using 0.15-1.0 mole of benzyl chloride per equivalent of nitrogen in component (c). The cellulose fiber materials after-treated in this manner possess very good wetfastness.

    Abstract: A water-dispersible powder or paste preparation of a water-insoluble dye contains at least one sodium salt of a water-soluble condensation product of (I) a naphthalene monosulphonic acid or derivative thereof and formaldehyde or (II) a mononuclear aromatic compound capable of reacting with 2 moles of formaldehyde, a napthol sulphonic acid, formaldehyde and optionally sodium sulphite, the content of inorganic salt in said preparation being less than 5%, preferably 0.5% by weight of compound (I) or (II). Products (I) and (II) may be prepared free from salts from the start by a conventional method or the conventional industrial product may be freed from salts by dialysis, ion exchange, electrolysis or precipitation with organic liquids. The preparations may also contain urea or thiourea as dispersion assistants. Suitable dyes are vat or disperse dyes. The preparations may be prepared by grinding, kneading or spray drying. Suitable products (I) and (II) are specified and examples are given.
