Abstract (en)
[origin: US4592757A] 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.
