A new method has been developed for applying microcapsules in the spinning process, in all yarns made on ring spinning machines, whether short fiber or long fiber. The mircocapsules were placed in the interstices of the yarn, before twisting. This solves the problem of permanence of the effect provided by the active ingredients contained in the mircrocapsule, for functionality and use of textile garments, against repeated washing. The method is technically and industrially feasible. This has been demonstrated by the interest shown by an important manufacturer of spinning machinery. The proposed method is valid for all types of fibers that are processed by the systems of carded cotton, worsted, semi-worsted, woolen and high bulk (HB) yarns when obtained in ring spinning machines. The new method of application is suitable for all types of microcapsules which are currently developed for use on textiles
