Abstract:
A process for the simultaneous dyeing and crease-proof finishing of textile material consisting of cellulose fibers or blends of cellulose fibers and polyester fibers by impregnating the textile material with an aqueous bath containing a reactive or vat dyestuff or a disperse dyestuff and a reactive or vat dyestuff, N-methylol-acrylamide or N,N-dimethylol-methyl-bis-acrylamide or an ether thereof with an alkanol containing 1 to 3 carbon atoms as well as an acid catalyst, dry heating the material to condense the N-methylol group of the synthetic resin and optionally fixing the disperse dyestuff at the same time, and in a second fixation step simultaneously fixing the reactive or vat dyestuff and the ambivalent cross-linking agent in an alkaline medium, and then after-treating the material by washing operations.
Abstract:
HOE 91/F 328 of the disclosure: Biodegradable spin finishes The invention relates to spin finishes which contain compounds of the formula HO(CH2CH20)x-RO-(CH2CH2O)yH I in which R is an alkylene radical which is mono- or polysubstituted by alkyl, has 2 to 4 carbon atoms in the alkylene chain and contains methyl, ethyl, propyl or isopropyl as the alkyl substituent, and the sum of x and y is 10 to 20, x and y being different from zero, and to a process for the spin finishing of fibers.

Abstract:
of the disclosure The novel urethanes correspond to the formula I below in which a denotes a number from 5 to 17 and b denotes a number from 1 to 7. These urethanes are prepared by reacting the corresponding perfluoroalkylethanol/epichlorohydrin adducts with toluelene diisocyanates. The novel aqueous dispersions are essentially composed of the novel urethanes, cationic or betaine emulsifiers and non-ionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic acid esters and alkanediols or polyalkanediols which can be etherified on one or both sides, in water. The novel urethanes and the novel aqueous dispersions are used to impart an oleophobic and hydrophobic finish to textiles, leather and furs. They are also suitable for the treatment of unpainted timber, for example unpainted furniture.

Abstract:
The novel urethanes are synthesised from aliphatic fluoroalcohol, isocyanate and a specific substituted phenol or aniline compound. They are prepared by reaction of an aliphatic fluoroalcohol with a di- or triisocyanate to form a fluoroalcohol/isocyanate adduct and by reaction of this adduct with a specific substituted phenol or aniline to give the desired urethanes. The urethanes are preferably used for the oleophobic and hydrophobic finishing of textiles and leather.
Abstract:
The novel urethanes, in addition to at least one perfluoroalkyl group, also contain epichlorohydrin groups and dialcohol radicals in the molecule. They are prepared by reacting a fluorine-containing alcohol with epichlorohydrin to give the perfluoroalkyl-epichlorohydrin adduct, reacting this adduct with a di- or triisocyanate to give the perfluoroalkyl-epichlorohydrin-isocyanate adduct and by reacting this adduct with a dialcohol or a monoetherified dialcohol to give the desired urethanes having a perfluoroalkyl group and having epichlorohydrin groups and dialcohol radicals, and by reacting a suitable urethane compound of this type with a perfluoroalkyl-containing di- or triisocyanate to give the desired urethanes having a plurality of perfluoroalkyl groups and having epichlorohydrin groups and dialcoholradicals. The novel urethanes are preferably used for the oleophobic and hydrophobic finishing of textiles.
