The study of conditions for the impregnation of microparticles, produced by complex coacervation, in textile fibers is the main step to confer new properties to fabrics via microtechnology. Aspects of durability of the new function and preservation of the properties of active cores may be ensured in the impregnation process. The purpose of this study is to evaluate the impregnation of microcapsules in different textile fibers, using binders and natural alternatives to improve their fixation.
