Preparation and characterization of an eco-friendly emulsion thickener with ultralow solid content

In order to improve the stiff hand feeling of pigment printing and overcome the oil pollution of traditional kerosene emulsion thickeners and electrolyte sensitivity of synthetic thickeners,novel O /W and W /O emulsion thickeners with ultralow solid content were prepared with special eco-friendly nonionic chemical MCSO-510 and a certain proportion of water.The impacts of different emulsifiers or emulsifier combinations on emulsion type,and viscosity,rheological property,storage stability and chemical compatibility of the novel emulsion thickeners were investigated.The experimental results showed that the emulsion thickener prepared with emulsifier combinations had higher viscosity than others,and the O /W emulsion thickener prepared with pure nonionic emulsifier had the best storage stability and chemical compatibility.The O /W emulsion thickener showed excellent application performance,with which,pigment printed silk displayed super-soft hand feeling and good color fastness.
