Abstract

The present invention relates to a composition and method for preparing a color stable and wash durable treated fabric with more even distribution of silver across the length of the treated textile.

First claim

We claim:

1 . A polymer bath composition comprising:
a) a first polymer comprising:
i) 60-90 wt % polymerized units of a monomer X selected from the group consisting of vinylimidazoles, vinylimidazolines, vinylpyridines, vinylpyrroles, derivatives thereof and combinations thereof; and
ii) 10-40 wt % polymerized units of a monomer Y which is an ethylenically unsaturated compound;
b) a second polymer comprising:
i) polymerized units of a heterocyclic monomer X; and
ii) polymerized units of monomer Y is a non-heterocyclic saturated compound selected from acrylic acid, (meth)acrylic acid, ethyl acrylate, and butyl acrylate and combinations thereof; and
c) silver.

2 . The composition of claim 1 wherein the silver is silver ion.

3 . A treated article comprising:
providing a fabric comprising the polymer bath composition of claim 1 .

4 . The treated article of claim 3 wherein the polymer bath composition when applied to the fabric has an average error less than 1.

5 . The treated article of claim 3 wherein the polymer bath composition when applied to the fabric has an average error less than 0.8.

6 . The treated article of claim 3 wherein the fabric is cotton.

7 . The treated article of claim 3 wherein the fabric is a blend polyester and lycra.

8 . The treated article of claim 3 wherein the fabric is polyester.
