Patent number: 4592757Abstract: Undyed or dyed wool with an antifelting finish is produced by a method in which the wool is chlorinated at a pH of less than 4 and then an aqueous solution of a quaternary product is applied onto the wool, this product being obtained by condensation of(a) piperazine and piperazine derivatives with(b) crosslinking agents, such as epichlorohydrin and ethylene chloride, in a molar ratio of from 1:0.9 to 1:1, and quaternization of the condensate with benzyl chloride, for 0.15 to 1.0 mole of benzyl chloride being employed per equivalent of nitrogen in component (a) in the quaternization.To produce dyed wool with an antifelting finish, dyeing is carried out after the wool has been chlorinated.Type: GrantFiled: May 1, 1985Date of Patent: June 3, 1986Assignee: BASF AktiengesellschaftInventors: Rolf Fikentscher, Heinrich Mertens, Klaus Reincke

Patent number: 4592758Abstract: Textile materials of natural polyamides or nylons, dyed with a dye containing acid groups, are after-treated with a dilute aqueous solution of a cationic condensate which is obtained by reaction of (a) piperazine or a derivative of piperazine with (b) a bifunctional crosslinking agent, such as an epihalohydrin, in a molar ratio of from 1:0.5 to 1:1.1, and quaternization of the condensate with benzyl chloride, from 0.15 to 1.0 mole of benzyl chloride being employed per equivalent of nitrogen in the component (a) during the quaternization. This after-treatment improves the wetfastness of the dye.Type: GrantFiled: May 1, 1985Date of Patent: June 3, 1986Assignee: BASF AktiengesellschaftInventors: Rolf Fikentscher, Heinrich Mertens, Klaus Reincke, Michele Vescia

Patent number: 4488879Abstract: This invention relates to dyeing textile materials of polyacrylonitrile or copolymers containing acrylonitrile in polymerized form with basic dyestuffs in aqueous dyeing liquors using the exhaust method employing retarders. The retarders are obtained by condensing (a) piperazine and piperazine derivatives with (b) ethylene chloride, epihalohydrin, propylene chloride, 1,3-dichloro-2-hydroxypropane, bis-epoxybutane, 1,4-dichlorobutene or their mixtures in mole ratios of 1:0.9 to 1:1.1. The condensation products are then quaternized with benzyl chloride using 0.8 to 1.5 moles of benzyl chloride per mole of component (a) for the quaternization. The aqueous solutions of the retarders either do not foam or show a very low foaming tendency.Type: GrantFiled: July 5, 1983Date of Patent: December 18, 1984Assignee: BASF AktiengesellschaftInventors: Rolf Fikentscher, Herbert Fleischer, Sigismund Heimann, Heinrich Mertens
