Abstract
The present invention provides durable and regenerable antimicrobial fibers and methods for preparing the same. These fibers have excellent colorfastness and washfastness, and are environmentally friendly. The antimicrobial fibers of this invention are suitable for a variety of purposes, including medical uses, sportswear, and uniforms.
Claims27
A fibrous composition, said fibrous composition comprising:
- a fiber;
- and
- a peroxycarboxylic acid functional group covalently attached to said fiber wherein said peroxycarboxylic acid functional group is derived from an organic acid having at least two carboxyl groups.
A process for preparing an antimicrobial fiber, said process comprising:
- (a) immersing a fiber in an aqueous treating solution comprising an organic acid, wherein said organic acid has at least two carboxyl groups;
- and
- (b) treating said fiber with an oxidizing agent to produce a peroxycarboxylic acid function, thereby preparing an antimicrobial fiber.
