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/m, an antibacterial activity value of at least 3.0, and/or antiviral activity value of at least 2.5.

Bactericidal and virucidal fabric

A launderable bactericidal and virucidal fabric finish formulation. The first component is a bactericidal and virucidal agent represented by formula (I): wherein n is 7; R, R, and Rare jointly or independently selected from H or one of the following groups:

Launderable bactericidal and virucidal fabric finish

The present invention provides an anti-pilling wool fabric with a coating having pilling resistance and resistance to fiber loss from fabric surface. The coating is formed by a coating formulation including at least two diisocyanates, at least two catalyst, a water dispersing agent, a buffer and water, which provides a polycarbodiimide crosslinker reactive to the relative less reactive groups on polypeptide of the wool fabric and promotes crosslinking between polypeptides of the wool fabric under relatively mild processing conditions so as to enhance mechanical strength of the wool fabric whilst no significant effect of the original finish merino wool fabric and/or garment and fiber loss from fabric surface are observed, compared to conventional treatment methods on wool fabric. A corresponding coating formulation and method of fabricating the anti-pilling wool fabric are also provided. The present invention is applicable to finished wool fabric which fibers are already with colorant(s), and/or dye(s), and/or reactive dye(s).
