Abstract: Methods for producing cellulose articles having controlled release of active ingredient include dispersing pulp in aqueous direct solvent for cellulose to form a slurry. Organically modified or ion-exchange-activated phyllosilicate is homogenized in a direct solvent for cellulose with exfoliation by shearing, then mixed with the slurried pulp. A mixture of active ingredient and a lipophilic matrix material or a water-in-oil (“W/O”) emulsion containing active ingredient is stabilized with thickener, converted into a gel-like paste, and mixed with the slurried pulp. Water is stripped from the mixture until all cellulose is dissolved, the mixture is formed into shaped articles, and dried. Exemplary active ingredients include cosmetic active ingredients, fat-soluble vitamins or apolar plant extracts. Domains of active ingredient and matrix material or emulsion containing active ingredient are present as fine divisions within the inventive articles.

Abstract: The invention describes electrically conductive shaped bodies with an inherent positive temperature coefficient (PTC), produced from a composition which contains at least one organic matrix polymer (compound component A), at least one submicroscale or nanoscale, electrically conductive additive (compound component B) and at least one phase-change material with a phase-transition temperature in the range from ?42° C. to +150° C. (compound component D). The phase-change material is incorporated into an organic network (compound component C). The electrically conductive shaped body with an inherent PTC effect is, in particular, a filament, a fibre, a spun-bonded web, a foam, a film, a foil or an injection-moulded article. The switching point for the PTC behavior is dependent on the type and also the phase-conversion temperature of the phase-change material. By way of example, a self-regulating surface heater in the form of a film, foil and/or textile can be realized in this way.

Abstract: The invention relates to molded cellulose bodies, in particular fibers, filaments, directly spun nonwovens, films, or foams which have flame-resistant properties. The fibers and filaments can be further processed as textiles into yarns, wovens, knitted fabrics, and nonwovens. The molded bodies are produced from solutions of cellulose and melamine cyanurate or cellulose and crosslinked or partially crosslinked melamine resin particles in an organic solvent. The melamine cyanurate or the melamine resin particles provide the molded cellulose bodies with flame-retardant properties. The molded cellulose bodies made of cellulose and melamine cyanurate or melamine resin particles can further contain flame retardants, in particular flame retardants which act synergistically, in a particulate form. The obtained textile fibers and nonwoven materials have a soft touch and can be processed or finished as filaments or yarns on conventional textile machines.

Abstract: What is described is a shaped cellulose body having physiologically active mineral substance compounds distributed therein, which are bound within the cellulose matrix of the shaped body and are distributed homogeneously over the cross section thereof. The mineral substance compound is soluble in water, and contains at least one element selected from the group comprising sodium, potassium, magnesium, calcium, iron, copper, manganese and zinc. Even after repeated washing, the shaped cellulose body still contains a high proportion of the mineral substance. It preferably takes the form of fibers, filaments, films or spunbonded webs formed from these fibers. It is especially intended for topical purposes on the human skin, specifically for cosmetic or dermatological purposes. These shaped bodies can be processed to give sheetlike structures, laminates, composite materials and webs, alone or in a mixture with other shaped bodies and fibers.
