Synthesis of soap free adhesive emulsion and its application in static flocking

The presence of some free surfactants in the adhesive prepared by trad itional emulsion polymerization will affect the bond ing force of the adhesive.To overcome this shortcom ing,soap-free acrylate adhesive was synthesized with polymerizable surfactants of sod ium monoalkylpolyoxyethylene maleates.The polymerization process of the soap-free adhesive emulsion was optim ized,and the product was characterized by FT-IR,particle size analyzer,TEM and DSC.The results ind icated that the resulting adhesive emulsion has uniform d istribution of particle size,good electrolyte resistance,and enhanced water repellency of the emulsion film.The emulsion was applied to static flocking,and the relationship between technological factors and flocking fastness was stud ied.The results showed that the soap-free adhesive had good bond ing force and the flocking fabric with this adhesive emulsion had good rubbing fastness(over 2 000 times),meeting the requirements of flocking fabric for garments.
