Abstract
This invention is directed towards fibers of fabric or other fibrous substrates coated with amine-containing polymers. These polymers impart durable anti-microbial activity, renewable control of certain odors, and the capacity to bind certain materials to the substrate surface.
Claims18
A finish for a fibrous substrate comprising an amine-containing polymer with reactive groups, a cross-linker, and a volatile solvent, and wherein the finish is durable to cleaning procedures.
A fibrous substrate comprising amine-containing polymers crosslinked on the fiber surface of the fibrous substrate to form a resinous coating durable to cleaning procedures.
A method for providing anti-microbial properties to a fibrous substrate, the method comprising:
- exposing the fibrous substrate to a treatment composition comprising an amine-containing polymer with reactive groups, a cross-linker, and a volatile solvent;
- and
- curing the fibrous substrate;
- to give a fibrous substrate exhibiting durable anti-microbial properties.
A method for providing a fibrous substrate with the ability to eliminate or greatly diminish offensive body odor, the method comprising:
- exposing the fibrous substrate to a treatment composition comprising an amine-containing polymer with reactive groups, a cross-linker, and a volatile solvent;
- and
- curing the fibrous substrate;
- to give a treated fibrous substrate which exhibits the ability to durably eliminate or greatly diminish offensive body odor.
A method for treating a synthetic fibrous substrate to provide durable finishes on the synthetic fibrous substrate, the method comprising:
- exposing the fibrous substrate to a first finish comprising an amine-containing polymer with reactive groups, a cross-linker, and a volatile solvent to give a treated fibrous substrate with reactive groups on its surface;
- curing the treated fibrous substrate;
- and
- exposing the treated fibrous substrate to a second finish containing groups that react with the reactive groups on the treated fibrous substrate;
- to give a synthetic fibrous substrate wherein the second finish is durable to cleaning procedures.
