Synergistic mixt. for treating textiles before dyeing, foularding, etc - comprises poly epihalohydrin and poly:alkylene-poly:amine amine, derived from an allyl amine, and textile auxiliary
Compsns. of formula (I) contain as active components (1) polymer (P1) obtd. by reacting epihalohydrin of formula (II) or precursor of (II) with a polyalkylenepolyamine of formula R3R3aN-(CH2)2-3-NH2 (III); (2) specified type of water-sol. homo- or co-polymer (P2); and (3) textile auxiliary (T) which is reaction mixt., opt. neutralised with acid, obtd. by (i) reacting (II) with ammonia then post-reacting with (II), or (ii) reacting (II) with methylamine or dimethylamine to form polymer of mol. wt. (as base) 500-10,000. (P2) is (a) homopolymer of a monoallylamine whose N atom(s) can form acid addn. sa (b) homopolymer of a monoallylamine whose N atoms occur as quat. ammonium gps.; (c) homopolymer of a diallylamine whose N atom(s) can form acid addn. sa (d) homopolymer of a diallylamine whose N atoms occur as quat. ammonium gps.; (e) copolymer of monomer of (a) and/or (b) with (c) and/or (d) and/or (g) triallylamine whose N atom(s) can form acid addn. salt and/or (h) triallylamine whose N atom(s) occur as quat. ammonium gps.; or (f) copolymer of monomer (a) and/or (b) and/or (c) and/or (d) and/or (g) and/or (h) with other copolymerisable. USE/ADVANTAGE - Pretreatment of substrates (claimed), partic. textile materials, esp. cotton, opt. mixed with other fibres. (I) permit shorter dyeing times and greater dyestuff pickup; even dyeing, foularding, and printing is obtd. with mixts. of fibres such as cellulose and small proportion of polyester, better fastness is obtd. on printing.
