| 摘要 |
The invention relates to hydroxyethyl carbamate and/or a hydroxypropyl carbamate modified low molecular polymer compound obtained by cross-linking a conversion product of a polycationic amine, obtained by condensation of a primary and/or secondary polyamine with dicyandiamide and by reacting this conversion product with ethylene carbonate or propylene carbonate. The invention also relates to the use of said polymer compounds as after-treatment agents to improve fastness properties, specially wet fastness, of cellulose-containing textile materials dyed or printed using substantive dyes or reactive dyes, wherein colorations or prints exhibiting excellent wet fastness can be obtained. |
