Abstract: The process for the visible marking of carrierless polymeric membranes for filtration purposes and for the reverse osmosis is characterized in that the marking symbols are first of all printed onto the casting support, onto which subsequently the casting mass is poured which serves for the production of the membrane. During the removing of the pre-solidified, solidified or finished membrane from the casting support, the printing dye which has an outline corresponding to the marking symbols, is taken up by the membrane and is taken along by the latter from the casting support. Preferably, the printing dye which had been imprinted onto the casting support when the membrane casting mass is poured on, has at least dried in a wipe-proof manner and, in this state, is soluble in the solvent-system of the membrane casting mass.

Abstract: A process for producing agglomerates of water-soluble dyes by adding a granulating auxiliary to at least one water-soluble dye, which is in pulverulent form, and converting the mixture, while it is being subjected to a tumbling and/or mixing action, by particle enlargement into a granular form, in which process there is used as a granulating auxiliary:(a) at least one compound of the formula IA--(CH.sub.2 CH.sub.2 O).sub.n --H (I)in which A is the group R--O-- or ##STR1## R is an aliphatic or alicyclic hydrocarbon radical containing 8 to 22 carbon atoms, R' is an aliphatic hydrocarbon radical containing 8 to 22 carbon atoms, and n is 10 to 200, or(b) a mixture of a compound of the formula II ##STR2## in which m is 50 to 500, and x is 3 to 5, with a compound of the formula IIIR.sub.1 --NH--CO--NH--R.sub.1 (III)in which each R.sub.

Abstract: Aqueous fabric softening compositions containing cationic softeners, amines, and certain 3-isothiazolones as antimicrobial agents are formulated at a pH below about 6 to improve the stability of the antimicrobial agent in the presence of the amine.

Abstract: A method for treating a fabric by the combined use of a permanent water repellent and softening agent and at least one of a sterilizing compound and a mould retardation compound so that the fabric is imparted washfast and antibiosis thereto which are maintained even after a number of washings.

Abstract: An agent for improving the color fastness of dyed cotton fibers and textiles to chlorinated water which comprises a specific diamine compound. The combination of the diamine and hydrolyzable tannin further increases the color fastness to chlorinated water. The tannin can be more strongly fixed to the fibers by further treating with a metal salt, whereby an excellent color fastness to chlorinated water can be maintained for a prolonged period of time.
