Abstract
A fluid set can include an ink composition having a pH from pH 7 to pH 10 and a crosslinker composition having a basic pH from pH 8 to pH 10. The ink composition can include from 60 wt % to 90 wt % water, from 5 wt % to 30 wt % organic co-solvent, from 1 wt % to 6 wt % pigment, and a latex polymer including an aromatic (meth)acrylate moiety. The crosslinker composition can include from 70 wt % to 95 wt % water, from 1 wt % to 25 wt % organic co-solvent, and from 1 wt % to 10 wt % polycarbodiimide.
Claims16
A fluid set, comprising:
- an ink composition having a pH from pH 7 to pH 10, the ink composition, comprising:
- from 60 wt % to 90 wt % water,
- from 5 wt % to 30 wt % organic co-solvent,
- from 1 wt % to 6 wt % pigment,
- a polymer dispersant having a weight average molecular weight from 8,000 MW to 28,000 MW and an acid number from 100 to 350, and
- a latex polymer including an aromatic (meth)acrylate moiety and including from 0 mol % to 4 mol % styrene;
- and
- a crosslinker composition having a basic pH from pH 8 to pH 10, comprising:
- from 70 wt % to 95 wt % water,
- from 1 wt % to 25 wt % organic co-solvent, and
- from 1 wt % to 10 wt % polycarbodiimide.
A textile printing system, comprising:
- an ink composition having a pH from pH 7 to pH 10, the ink composition, comprising:
- from 60 wt % to 90 wt % water,
- from 5 wt % to 30 wt % organic co-solvent;
- from 1 wt % to 6 wt % pigment,
- a polymer dispersant having a weight average molecular weight from 8,000 MW to 28,000 MW and an acid number from 100 to 350, and
- a latex polymer including an aromatic (meth)acrylate moiety and including from 0 mol % to 4 mol % styrene;
- a crosslinker composition having a basic pH from pH 8 to pH 10, comprising:
- from 70 wt % to 95 wt % water,
- from 1 wt % to 25 wt % organic co-solvent, and
- from 1 wt % to 10 wt % polycarbodiimide;
- and
- a fabric substrate.
A method of textile printing, comprising:
- ejecting an ink composition having a pH from pH 7 to pH 10 on a fabric substrate, the ink composition comprising from 60 wt % to 90 wt % water, from 5 wt % to 30 wt % organic co-solvent, from 1 wt % to 6 wt % pigment, a polymer dispersant having a weight average molecular weight from 8,000 MW to 28,000 MW and an acid number from 100 to 350 and a latex polymer including an aromatic (meth)acrylate moiety and including from 0 mol % to 4 mol % styrene;
- separately ejecting a crosslinker composition having a basic pH from pH 8 to pH 10 onto the fabric substrate, the crosslinker composition comprising from 70 wt % to 95 wt % water, from 1 wt % to 25 wt % organic co-solvent, and from 1 wt % to 10 wt % polycarbodiimide, and
- reacting a (meth)acrylic acid surface group of the latex polymer with the polycarbodiimide of the crosslinker composition on the fabric substrate.
