The study demonstrated that chemically modified wheat gluten reduces formaldehyde emissions from pigment print pastes on fabrics. Gluten was chemically modified by three methods. Deamidation of gluten was performed with sodium hydroxide, and methyl acrylate and ethyl alcohol groups were grafted on gluten. Print paste formulations were prepared with each type of chemically modified gluten, a commercial ethylene urea scavenger and no formaldehyde scavenger. Two types of auxiliary resins (i.e., melamine‐formaldehyde and hexamethoxymelamine‐formaldehyde resins) and four types of binders (i.e., acrylic, butadiene‐acrylic, butadiene‐styrene, and vinyl acetate) were used in conjunction with each of the scavengers. The print paste formulations were applied to cotton polyester poplin fabric and the abilities of the gluten and ethylene urea scavengers to reduce formaldehyde emissions were evaluated. Chemically modified gluten scavengers absorbed as much formaldehyde as the ethylene urea scavengers that are presently used in industry.
