Abstract
Hydrophilic additives are provided which may be introduced into fibrous articles to provide improved water absorbency and charge dissipation properties which resist abrasion and laundering. The fibrous articles are treated by contacting the articles with at least one hydrophilic additive, polyfunctional reactant and nitrogen catalyst under conditions sufficient to incorporate hydrophilic additive, polyfunctional reactant and nitrogen catalyst in the articles, followed by heating the fibrous articles to obtain the desired fiber characteristics.
