Abstract: 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; R1, R2, and R3 are jointly or independently selected from H or one of the following groups: wherein R4 is selected from CH3 or H; m is an integer from 2 to 10; p is an integer from 9 to 15; q is an integer from 2 to 10. A second component includes one or more crosslinkers and/or one or more catalysts. A third component includes one or more transition metal salts.

Abstract: 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.

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.

Abstract: The present invention discloses a cross-linked nanoporous saccharide-based material comprising saccharides as building blocks, also referred as nanoporous Nanosponge materials. The reaction of saccharides with cross-linkers at different saccharides to cross-linker ratios in one-pot shall allow formation of nanoporous Nanosponge material. This method further allows introduction of new functional groups on this material by the use of suitable cross-linkers and surface grafting agents, and these functional groups shall be able to provide different interaction forces with water, volatile organic vapors (VOCs) and metal ions. Along with larger inner surface area owing to the presence of nanopores or nanocavities in comparison to porous materials, saccharide-based nanoporous Nanosponge materials shall find broad applications in thermal insulation, water retention, hydrophobic finishes, odor removal properties, and metal ions exchange or absorption from water or soil.
