Textile printing

Abstract

A textile printing system can include an ink composition and a fabric substrate. The ink composition can include water, organic co-solvent, from 0.5 wt % to 10 wt % pigment, wherein the pigment has a dispersant associated with a surface thereof, and from 0.5 wt % to 20 wt % latex particles including styrene (meth)acrylic polymer having an acid number from 0 mg KOH/g to 60 mg KOH/g and a glass transition temperature from −30° C. to 50° C. The latex particles are uncrosslinked.

         5 . The textile printing system of  claim 1 , wherein the styrene (meth)acrylic polymer includes, based on a total weight of the latex particles, from 10 wt % to 35 wt % styrene moieties, and from 65 wt % to 90 wt % of (meth)acrylic moieties. 
     
     
         6 . The textile printing system of  claim 5 , wherein the (meth)acrylic moieties includes two or more of 2-ethylhexyl acrylate, acrylic acid, methyl methacrylate, n-butyl acrylate, iso-butyl acrylate, and tert-butyl acrylate. 
     
     
         7 . The textile printing system of  claim 5 , wherein the (meth)acrylic moieties include 2-ethylhexyl acrylate at a total 2-ethylhexyl acrylate to styrene weight ratio of 2:1 to 1:2. 
     
     
         8 . The textile printing system of  claim 5 , wherein the (meth)acrylic moieties includes one or more isomer of butyl acrylate at a total butyl acrylate to styrene weight ratio of 2:1 to 1:2. 
     
     
         9 . The textile printing system of  claim 1 , wherein the fabric substrate includes cotton, polyester, nylon, silk, or a blend thereof. 
     
     
         10 . A method of textile printing, comprising ejecting an ink composition onto a fabric substrate, wherein the ink composition comprises:
 water,   organic co-solvent,   from 0.5 wt % to 10 wt % pigment, wherein the pigment has a dispersant associated with a surface thereof, and   from 0.5 wt % to 20 wt % latex particles including styrene (meth)acrylic polymer having an acid number from 0 mg KOH/g to 60 mg KOH/g and a glass transition temperature from −30° C. to 50° C., wherein the latex particles are uncrosslinked.   
     
     
         11 . The method of  claim 10 , wherein the styrene (meth)acrylic polymer has an acid number from about 20 mg KOH/g to about 55 mg KOH/g and an average particle size from 75 nm to 350 nm. 
     
     
         12 . The method of  claim 10 , wherein the styrene (meth)acrylic polymer includes, based on a total weight of the latex particles, from 10 wt % to 35 wt % styrene moieties, and from 65 wt % to 90 wt % of (meth)acrylic moieties. 
     
     
         13 . The method of  claim 10 , further comprising curing the ink composition on the fabric substrate at a temperature from 100° C. to 200° C. for from 30 seconds to 5 minutes. 
     
     
         14 . A textile printing system, comprising:
 a fabric substrate;   an inkjet printer to eject an ink composition on the fabric substrate, the ink composition, comprising:
