Method for providing an anti-microbial and an anti-pilling effect and for improving dye uptake to textiles, novel co-polymers and textiles

A method for providing an anti-microbial and an anti-pilling effect and for improving dye uptake to a textile, said method comprising

• (i) treating said textile with an aqueous solution comprising
• a) at least one co-polymer made of a monomer of general formula (I)
• or mixture thereof,
• and a monomer of general formula (II)
• or mixture thereof,
• wherein
• X is, each independently selected from the following (A) or (B) chains
• the stars indicate the bonds linked to the oxygen and nitrogen atoms in the monomers of formula (I) and formula (II);
• n is, each independently, an integer from 1 to 10;
• and
• Alk is a C1-C4 alkyl group;
• and wherein the tertiary amino groups in formula (I) are partially quaternized with halo-long chain alkyl groups;
• and
• b) at least one aliphatic or cycloaliphatic diisocyanate;
• and
• (ii) optionally drying and/or fixing said textile.
