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 and nitrogen catalyst under conditions sufficient to incorporate additive and catalyst in the article, followed by heating the treated article to obtain the desired fiber characteristics.
