Abstract (en)

[origin: DE19736542A1] Wool with an anti-felting finish is obtained by subjecting dyed or undyed combed top wool to pretreatment with a low-pressure plasma and then treating it with an aqueous dispersion of self-dispersing isocyanate. The self-dispersing isocyanates have an isocyanate content of 1-25% and are obtained by reacting (A) polyisocyanates with an average NCO functionality of 1.8-4.2 with (B) polyalkylene oxide-alcohols, -amines and/or -thiols of formula R<1>R<2>N-(CHX-CHY-O)n-CHX-CHY-ZH (I) and optionally (C) other NCO- reactive compounds with actual or potential anionic or cationic groups, in which n = 3-70; X, Y = H or methyl (if X or Y is methyl, the other must be H); R<1>, R<2> = 1-6C alkyl or acyl (if R<1> = acyl, R<2> may also be H), and R<1> + R<2> may be tetra-, penta- or hexa-methylene, optionally with one or two CH2 groups replaced by O and/or NH and/or with 1 or 2 CH2 groups substituted with methyl; Z = O, S or NH . An Independent claim is also included for self-dispersing isocyanates as described above.
