| abstract |
The present invention concerns a Binder (comprising sulfamic acid, ammonium sulfamate and ammonium sulfate) and process of production of fabrics containing cyclodextrins fixed to the binder. More precisely, the present invention allows to fix a binder to natural, synthetic or artificial fibers, and, by means of thermal processes, to fix cyclodextrins to the same binder, giving rise to fabrics suitable to incorporate active principles and to release them along with time. Peculiar characteristics of said binder are its abilities to interact with several types of fabric, independently of their composition, and with several types of cyclodextrin. Other peculiarities of the invention are: the ability to produce functionalized fabrics, adapted to be weighted with desired molecules and release them gradually along time, with a process that does not alter the original characteristics of the fabric; the possibility of repeating several times the weighting of such molecules, so as to be able to define such fabrics as "reloadable" or "rechargeable". |
