Development of green waterborne UV-curable vegetable oil-based urethane acrylate pigment prints adhesive: Preparation and application

The energy consumption and environment pollution play an important role to the sustainable development in the dyeing and finishing industry. The aim of this study is to synthesize a series of acrylated epoxidized soybean oil based UV-curable polyurethane pigment adhesives and to reduce the consumption of energy and environment pollution in pigment printing process. The chemical composition was evaluated using fourier transform infrared spectra and nuclear magnetic resonance hydrogen spectroscopy. The thermal properties of UV-cured films were discussed by thermalgravimetric analysis (TGA) and differential scanning calorimetry (DSC). In addition, the effects of AESO content on particle size, water swelling properties and contact angles of the emulsions and films were investigated. Furthermore, the color yield, the rubbing fastness and washing fastness of the printed fabrics with acrylated epoxidized soybean oil based UV-curable polyurethane as adhesive were evaluated. The application of vegetable oil-based urethane acrylate pigments of cotton fabrics is a cleaner method that can reduce the consumption of energy and environment pollution. Compared to conventional thermally curable coatings, the UV-curable vegetable oil-based urethane acrylate pigment prints adhesive does not require a large amount of water and energy, indicating that vegetable oil-based urethane acrylate pigments have potential application in the cleaner production of textile industry.
