Title: Method for binding compounds to textiles

Abstract: A method to bind compounds (e.g., antibiotics) to natural or synthetic yarn or fabric, involving reacting the compounds with cyanuric chloride, a hydroxide base (e.g., NaOH), and deionized water to form reactive compounds; forming a dyebath composed of the reactive compounds, at least one nonioinic, cationic or anionic surfactant, salt (e.g., sodium sulfate), deionized water, and natural or synthetic yarn or fabric; heating the dyebath (generally for about 1 to about 100 minutes at a temperature of about 25.degree. to about 100.degree. C.); adding a hydroxide base (e.g., NaOH) to the dyebath and heating (generally for about 1 to about 100 at a temperature of about 80.degree. to about 100.degree. C.); rinsing the natural or synthetic yarn or fabric; placing the natural or synthetic yarn or fabric in deionized water and heating (generally for about 1 to about 100 minutes at a temperature of about 25.degree. to about 100.degree. C.); rinsing the natural or synthetic yarn or fabric; and drying the natural or synthetic yarn or fabric. Also natural or synthetic yarn or fabric bound to antibiotics prepared by the method are disclosed herein.
