 O Introduction cotton fabric traditional 2D resin finishing, with good wrinkle resistance, but there are serious strength loss, reduce wear, feel hard, yellowing, and formaldehyde release. In recent years, more foreign ionic crosslinking method for durable press finishing of cotton fabrics, and the domestic rarely reported. Ionic crosslinking method can improve the the finished fabrics wrinkle resistance, and lower fabric strength loss, good whiteness, has antibacterial properties, and can improve the dyeability. Cotton fabrics ionic crosslinking methods are mainly four categories: (1) cotton fabric anion and a polycation electrolyte ionic crosslinking; (2) cotton fabric cationized with a polyanion electrolyte ionic crosslinking; (3) Cotton after the fabric is treated with the ion species to pre-polycondensation, with oppositely charged polyelectrolyte ionic crosslinking; (4) the cotton fabric in the presence of the female, the solution of the ionic crosslinking of the cationic substance. Used in this assay method (1), CAA (trichloroacetic acid) on cotton fabric anion, and then crosslinked with cationic glycerol (CG) to study the impact of the cotton fabric wrinkle resistance and other properties.
