is occluded and fixed in the matrix uniformly both inside and outside and even among the fibers the compound alkaline copper sulphate occluded and fixed to the matrix is an insoluble precipitate in the presence of humidity ambient humidity and that of the microorganisms which are in contact with it leaves free ions which rearranged again into the form of soluble dissociated copper sulfate process that occurs slowly under control said soluble dissociated cuso 4 due to the characteristic of high solubility leaves immediately cupric ions available in the humid environment which finally exert the biocidal effect of high activity which manifests itself in time in a gradual and controlled manner this property of insolubility of the precipitated alkaline copper sulphate doses ions in the medium in the presence of moisture this dosage is minimal in mass ratio of copper occluded in the matrix and which ensures durability and permanence in time even when multiple washes were performed the greatest losses will be given by the possible washing of the matrix but these are minimal in relation to the mass of the fixed and occluded compound because of the antimicrobial properties particularly antibacterial and antifungal properties that acquires the matrix it is possible a variety of uses as the biological properties of the parent applications are combined prominent among these uses but not limited to fabrics paper cardboard leather among others with.
