A novel microlatex of styrene/2‐ethylhexylacrylate (2‐EHA)/2‐hydroxyethyl methacrylate (2‐HEMA)/N‐(isobutoxy methyl) acrylamide (IBMA) copolymer was synthesized and mixed in sublimation inks to be inkjet printed on the cotton fabric to provide soft hand feel and good color fastness after heat‐press. In the optimized microemulsion composition with highest monomer mixture amount, polymerizable maleate surfactants with moderate EO value attained smaller microemulsion droplet size in mono distribution and lower dosage than conventional POE surfactants in combination with anionic surfactants. With adopted semicontinuous process in microemulsion copolymerization at 65°C, the polymerizable surfactants stabilized the growth of microlatex particle size within 70 nm in 240 min and attained 100% of monomer conversion rate with two initiator systems, 2‐2‐azobis(2‐methlypropionamidine dihydrochloride (AAPH) and tert‐butylhydroperoxide (TBHP)/sodium formaldehyde sulfoxylate (SFS). The microlatex particle size of two surfactant systems increased with higher conversion rate and reaction temperature, which synchronized with initiator concentration. High polymer solid content was contributed mainly by IBMA monomer ratio requiring higher amounts of anionic surfactants and 2‐HEMA as a cosurfactant in particle stabilization. Although the optimum ink containing high IBMA microemulsion exhibited small variation in viscosity, pH value and surface tension, disperse dyes in four colors had different interaction with the microlatex to demonstrate distinct printing durability and color performance. The resulted cotton fabric attained high K/S value for color strength, great AATCC grade for color fastness, and nearly zero color difference for negative dye particle diffusion or migration. © 2011 Wiley Periodicals, Inc.

When plastic film packaging is processed for reuse, residual ink colors the polymer and makes the polymer less stiff, weaker,
and denser than the original material. These problems can be avoided if the printing is removed from the plastic film surface.
In this study, a commercial polyethylene film with water-based ink printing was deinked (the ink was removed) using nonionic
surfactants under a variety of conditions, and the effect of some parameters related to the deinking process were quantified
and optimized. Nonylphenol polyethoxylate, ethoxylated alcohol at a pH of 10, and ethoxylated amine at either acidic, neutral,
or basic pH level were identified to be effective at deinking. The hydrophiliclipophilic balance (HLB) value and the cloud
point are useful parameters for characterizing the effectiveness of nonionic surfactants. For optimal deinking, the HLB of
the nonionic surfactants should be as small as possible or the cloud point as low as possible without the deinking temperature
substantially exceeding the cloud point. Information related to scaleup of the process was also developed. Soaking plastic
film in surfactant solution prior to mechanical agitation significantly decreased the needed agitation time to achieve a given
level of deinking. Deinking decreases as the plastic/solution ratio (consistency) increases, and cutting plastic film into
smaller pieces improves the deinking at moderate consistency. Increasing agitation speed also enhances the deinking. Experiments
performed with pilot-sized paper deinking apparatuses demonstrated that deinking of plastic film using surfactants is technically
feasible.
