Conclusions
Wrinkle resistance in cellulosic
fabrics can be achieved with ionic crosslinks. Carboxymethylated woven cotton
fabric treated with cationized chitosan showed significant increases in wrinkle
angle recovery without strength loss. This process allows for enhanced wrinkle
resistance without the chance of formaldehyde release.
