Abstract
The present invention provides, inter alia, durable and regenerable microbiocidal textiles and methods for preparing same. Such textiles can be readily prepared using a wet finishing process to covalently attach a hetercyclic N-halamine to a cellulose based material or other polymeric material. Once prepared, the textiles of the present invention have a broad spectrum of biocidal activity against pathogenic microorganisms. Moreover, the biocidal activity of such textiles can be regenerated by washing with a halogenated solution.
Claims8
A textile composition comprising:
- a textile material, wherein said textile material is a member selected from the group consisting of cellulosic, cellulosic-polyester and polyester material;
- and
- a heterocyclic N-halamine covalently attached to said textile material.
