A method for preparing a cosmetic component is provided which includes applying a layer of a dry cosmetic ingredient between a pair of fibrous sheets obtained by electrospinning one or more polymeric materials at least one of which is capable of cold flow under pressure. Sufficient pressure is then applied to the layers of fibrous sheets to cause cold flow of at least some of the polymeric material such that at least parts of the fibrous sheets bond with each other and entrap the cosmetic ingredient in position between them and prevent it from migrating between the sheets during further processing or handling.

The present invention relates generally to compositions comprising polyelectrolytes complexes (PECs) of anionic and cationic biopolymers capable of forming barriers on fiber based materials. Also disclosed is a fibre based material with a barrier coating against oil and water, wherein the material is provided with a barrier from at least two layers formed from at least one composition comprising a polyelectrolyte complex (PEC) of a cationic biopolymer and an anionic biopolymer, The two layers result in improvements in both oil resistance and water resistance compared to the same material provided with a single layer of said at least one composition.

A functional cashmere fiber includes a cashmere fiber, a boron-doped TiO.sub.2 layer and a carboxymethyl cellulose (CMC) binder. The CMC binder binds the boron-doped TiO.sub.2 layer on the cashmere fiber such that the boron-doped TiO.sub.2 layer at least partially covers the cashmere fiber. The functional cashmere fiber provides self-cleaning function under visible light and high washing stability.

A treated cellulosic material comprising a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising a polymer comprising a modified cellulose polymer; and a modifying agent comprising a hydrophobic amine, a metal ion, or a quat. The present disclosure further describes a method for preparing a treated cellulosic material comprising (a) providing a cellulosic material; (b) a first treatment protocol comprising impregnating the cellulosic material with a dispersion comprising a polymer, the polymer comprising a modified cellulose polymer; and (c) a second treatment protocol comprising impregnating the cellulosic material with a modifying agent, the modifying agent comprising a hydrophobic amine, a metal ion, or a quat.

An object of the present invention is to make it possible that a pyridine antibacterial/antifungal agent is dispersed stably in a liquid for appropriate impartation of the pyridine antibacterial/antifungal agent to fibers, and that when fibers are processed with the agent which is mixed with various other treating agents such as dyes and softeners, there is no negative influences on the process of the fibers for imparting antibacterial/antifungal properties. An antibacterial/antifungal properties-imparting agent contains a pyridine antibacterial/antifungal agent; a modified polysaccharide having reduced hydroxyl groups; and a wetting agent; but does not contain a surfactant. After applying the antibacterial/antifungal properties-imparting agent to fibers, the fibers undergo a heating process.
