Abstract
The present invention provides a bactericidal and virucidal fabric selected from cotton or non-woven fabric prepared by formulations and methods described herein. The formulations include a beta-cyclodextrin-containing compound associated with one or more metal ions including at least zinc ions and water for providing bactericidal and virucidal properties to the fabric dip-coated with the formulations according to various embodiments of the present invention. The as-prepared fabric has an increment in Grams per Square Meter (GSM) value of approximately 13.0 to 20.0 g/m2, an antibacterial activity value of at least 3.0, and/or antiviral activity value of at least 2.5.
Claims8
A dip-coating, antibacterial and antiviral formulation for preparing a bactericidal and virucidal fabric, the formulation comprising:
