Water‐Based Pigment Digital Inkjet Dyeing of Cotton Fabric Using of Self‐Cross‐Linking Grafted Silicone Polyacrylate Emulsions

ABSTRACT “Spraying instead of dyeing” is a new clean dyeing technology that can achieve low/no water washing and shorter processes for cotton fabrics, which is conducive to the transformation, upgrading and sustainable development of textile printing and dyeing. In this paper, a self‐cross‐linking grafted silicone polyacrylate (SGSP) latexes were first prepared as a binder. Then, the pigment digital inkjet was used on cotton fabrics without washing, achieving energy saving, emission reduction, and carbon reduction. The effects of the mass of methacryloyl‐terminated polydimethylsiloxane (PDMS‐MA) and glycidyl methacrylate (GMA) on the hydrophobicity, thermodynamics, and mechanical properties of latex films were investigated, and the influences of pigment digital inkjet dyeing process on the wearability of spray‐dyed cotton fabrics (SDCF) were studied. Results indicated that when the mass of PDMS‐MA was 30 wt% and the GMA was 3%, the SGSP latex film had excellent hydrophobicity and mechanical properties. Meanwhile, under the process conditions of binder dosage of 30%, baking temperature of 160°C, and baking time of 4 min, SDCF had low hardness, good air permeability, and the color fastness to rubbing to the level of commercially available binders. This study presents clean dyeing technology and provides a valuable outlook into the future of binder production and application.
