A fabric freshening composition includes from about from about 1×10.sup.2 to about 1×10.sup.9CFU/g of the composition, of bacterial spores; and cyclodextrins.

The invention relates to a ball game racket frame (12) including a head portion (14), a shaft portion (18) and a grip portion (20). The ball game racket frame (12) comprises a fiber composite material having fibers embedded in a matrix. At least 5% of the fibers are natural fibers in at least one cross-section (28, 28a, 28b, 28c, 28d, 28e) of a portion of the ball game racket frame (12).

The invention further relates to a ball game racket frame (12) in which the proportion of natural fibers in at least one cross-section (28b, 28c, 28d, 28e) of the shaft portion (18) and/or the grip portion (20), respectively, is greater than the proportion of natural fibers in at least one cross-section (28, 28a) of the head portion (14).

The invention further relates to a method for manufacturing such ball game racket frames (12).

A liquid bioactive composition is provided that includes an enzyme 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 the enzyme in the liquid bioactive coating material is capable of enzymatically degrading of one or more components of the biological stain to facilitate biological stain removal from a substrate.

Bioactive coatings that include a base and a protein associated with the base for actively promoting the removal of organic stains are provided. In aspects, bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.

The invention provides fabrics that incorporate a cold-adapted trypsin derived from a fish or a crustacean, which trypsin inactivates viruses. The fabrics of the invention may be used in the production of various items of self-sterilizing protective equipment including gowns, sheets, curtains, surgical hats, surgical booties and protective facemasks.

This invention relates to the Chemical Composition for impregnation via spraying on disposal surgical masks and sleeved gowns made from hydrophilic and hydrophobic materials to inactivate bacteria and viruses, comprising of colloidal silver nanoparticles, Isopropanol Alcohol/Ethanol Alcohol Chlorhexidine/Quaternary Ammonium Compound, Peppermint/Spearmint Essential oils and water.

An activated cotton material and a method for processing cotton to form the activated cotton material are provided. The activated cotton material includes a layer of natural wax that is locked to the surface of cotton fibers by a wax lock.

A protective pad or garment portion, garments, and individual layers, being a moisture wicking layer, a core moisture absorbing layer and a moisture impermeable layer, and combinations thereof are disclosed.

A method of treating a surface including treating the surface with bacterial spores and Saccharomyces supernatant.

The disclosure provides a method for improving the strength and dyeing of wool fibers, and belongs to the technical field of modification of textile materials. By using the feature that protein fiber macromolecules contain a large number of active groups such as hydroxyl groups, amino groups and carboxyl groups, which easily react with polyphenolic pigments formed by a phenolic compound catalyzed by an enzyme to form covalent bonding, the disclosure realizes low temperature dyeing of wool fibers while improving the fiber strength. The disclosure has mild operating conditions easy to control, and in view of increasingly emphasis on environmental protection nowadays, the use of the biological enzyme for dyeing wool fibers is safe, environmentally friendly and efficient, and has a long-term development prospect.
