Abstract

A fluid set for textile printing can include an ink composition including an ink vehicle, pigment, and from 1 wt % to 15 wt % epoxide-reactive polymer. The fluid set can also include a fixer fluid including a fixer vehicle, and from 0.5 wt % to 12 wt % of a multiepoxide-containing resin.

First claim

What is claimed is:

1 . A fluid set for textile printing, comprising:
an ink composition including:
an ink vehicle,
pigment, and
from 1 wt % to 15 wt % epoxide-reactive polymer; and
a fixer fluid including:
a fixer vehicle, and
from 0.5 wt % to 12 wt % of a multiepoxide-containing resin.

2 . The fluid set of claim 1 , wherein the multiepoxide-containing resin is an oligomer or polymer having the structure:

where n is from 0 to 30, A is independently C m H 2m+1 , and m is from 0 to 5.

3 . The fluid set of claim 1 , wherein the pigment includes a surface with an epoxide-reactive group.

4 . The fluid set of claim 1 , wherein the epoxide-reactive polymer includes reactive groups selected from amine, carboxyl, hydroxyl, acid anhydride, phenol, thiol, or a combination thereof.

5 . The fluid set of claim 1 , wherein the epoxide-reactive polymer is a polyurethane binder.

6 . The fluid set of claim 5 , wherein the polyurethane binder is an anionic aliphatic polyester-polyurethane.

7 . The fluid set of claim 1 , wherein the fixer vehicle comprises water and an organic co-solvent, the water being present in the fixer composition in an amount from 65 wt % to 96 wt % and the organic co-solvent being present in the fixer composition in an amount from 1.5 wt % to 32.5 wt %.

8 . A textile printing system, comprising:
a fabric substrate; an ink composition including:
an ink vehicle,
pigment, and
from 1 wt % to 15 wt % epoxide-reactive polymer; and
a fixer fluid including:
a fixer vehicle, and
from 0.5 wt % to 12 wt % of a multiepoxide-containing resin.

9 . The textile printing system of claim 8 , wherein the fabric substrate includes cotton, polyester, nylon, wool, or a blend thereof.

10 . The textile printing system of claim 8 , wherein the fabric substrate includes a surface with an epoxide-reactive groups located to react with the multiepoxide-containing resin after contact therewith to affix the epoxide-reactive polymer to the fabric substrate through the multiepoxide-containing resin.

11 . The textile printing system of claim 8 , wherein the epoxide-reactive polymer includes reactive groups selected from amine, hydroxyl, acid anhydride, phenol, thiol, or a combination thereof.

12 . The textile printing system of claim 8 , wherein the epoxide-reactive polymer is a polyurethane binder with amine surface groups.

13 . A method of printing, comprising:
jetting a fixer fluid onto a fabric substrate, wherein the fixer fluid includes a fixer vehicle and from 0.5 wt % to 12 wt % of a multiepoxide-containing resin; jetting an ink composition onto the fabric substrate, wherein the ink composition includes an ink vehicle, pigment, and from 1 wt % to 15 wt % epoxide-reactive polymer; and reacting the multiepoxide-containing resin with the epoxide reactive polymer on the fabric substrate.

14 . The method of claim 13 , wherein the multiepoxide-containing resin and the epoxide-reactive polymer are jetted onto the print media substrate at a resin to polymer weight ratio from 0.05:1 to 3:1.

15 . The method of claim 13 , wherein reacting includes heating the fabric substrate having the fixer fluid and the ink composition in contact thereon to a temperature of from 80° C. to 200° C. for a period of from 5 seconds to 30 minutes.
