Abstract
The present invention discloses a novel system for preparing fabrics with antibacterial properties by sonochemically impregnating the fabrics with proteinaceous microspheres loaded with antibiotic. Antibacterial fabrics are widely used for production of outdoor clothes, under-wear, bed-linen, bandages, etc.
Claims38
A method useful for ultrasonically impregnating textiles with microspheres which may or may not be loaded with an effective measure of at least one predefined agent, said method comprising steps of
- a. preparing an aqueous solution containing a protein;
- b. layering an organic solvent above said aqueous solution;
- c. immersing a textile in said aqueous solution;
- d. adding a predetermined agent to said aqueous solution;
- e. irradiating said mixture with high-intensity ultrasonic power;
- f. controlling the temperature of said mixture during said irradiation;
- and,
- g. washing said textile to remove the residue of unbound microspheres and pristine protein molecules;
- wherein the reaction creating the microspheres and impregnating the fabric with them occurs in a two-phase system during step e.
Textiles imparted with improved properties by means of ultrasonic irradiation of said textiles in said mixture, thereby attaining uniform impregnation of said properties in said textiles.
