| abstract |
A water-soluble, triazine-based, non-dye, cellulose cross-linking agent that has a highly flexible linking group between at least two, mono-reactive cross-linking moieties and further hydrophilic or non-hydrophilic substituents, being preferrably represented by the general formula (I): (R1)(X1)T-L1-B-T(X2)(R2) wherein: R1 et R2 are cellulose-unreactive substituent groups on the s-triazine (T) and may be the same or different, X1 and X2 are leaving groups on the s-triazine which are lost on reaction with cellulose and may be the same or different, L1 et L2 are linking groups, an may be the same or different or absent, B is the bridging group comprising or consisting of at least one aliphatic polyoalkylene chain. |
