A substrate or coating is provided that includes a protease with enzymatic activity toward a component of a biological stain. Also provided is a process for facilitating the removal of a biological stain is provided wherein an inventive substrate or coating including a protease is capable of enzymatically degrading of one or more components of the biological stain to facilitate biological stain removal from the substrate or said coating.

This invention relates to odor control molecules comprised of polyethyleneimine compounds containing N-halamine and derivatives thereof.

A textile includes a substrate and a coating applied to a surface of the substrate. The coating includes a plurality of bilayers positioned one on top of the other. Each bilayer includes a first layer including a cationic polymer and a second layer comprising an anionic polymer. The cationic polymer in the first layer includes a polyethyleneimine (PEI), a poly(vinyl amine) (PVAm), a poly(allyl amine) (PAAm), a polydiallyldimethylammonium chloride (PDDA), or a chitosan (CH). The anionic polymer in the second layer includes a poly(acrylic acid) (PAA), a poly(styrene sulfonate) (PSS), a poly(methacrylic acid) (PMAA), a poly(sodium phosphate) (PSP), or a poly(vinyl sulfate) (PVS).

A nano-zinc oxide-supported bacterial cellulose microfiber-alginate fiber composite is described. The composite is obtained by absorbing nano-zinc oxide-supported bacterial cellulose microfibers on an alginate fiber spunlace non-woven fabric; the nano-zinc oxide is uniformly distributed on the surface of the bacterial cellulose microfibers. This composite has good biocompatibility, mechanical properties and water absorption properties, and has a great application prospect in biomedical fields, such as wound dressings, human body repair materials, tissue engineering materials, etc.

The present invention relates to an anti-microbial finish on the fabrics. The present invention particularly relates to an antimicrobial microencapsulated fabric finish composition comprising Neem extract and Azadirachta derived from flower and fruits of Azadirachta indica. The invention relates an antimicrobial finish coat on fabrics, particularly Terry towels. Further the invention relates to method of finishing of fabric with antimicrobial composition of Azadiracta indica, to provide a durable and anti-microbial fabric, wherein the fabric is preferably terry towel and woven plain fabrics like sheetings and bed linen.
