  • Patent number: 11508504
    Abstract: The invention relates to an electric winding body which has improved performance characteristics as a result of being impregnated with a thermoplastic material filled with phase change material. These performance characteristics relate to improved heat dissipation, vibration damping, fixing of the coils, and improved protection against overheating by utilizing the sensitive and latent heat storage properties when the polymer units transition from the semi-crystalline state into the amorphous state.

  • Publication number: 20220341061
    Abstract: The invention relates to a cellulosic fibre loaded with a biologically active substance formed by the steps of: a) producing a cellulosic fibre loaded with ion exchanger, b) after-treating the fibre thus produced with an aqueous solution of a metal salt which exhibits antibacterial activity and/or antiviral activity, and c) after-treating the loaded fibre with an aqueous fixing solution to convert the metal salt into a water-insoluble form. The cellulosic fibres thus produced can be used to form textile fabrics, wound dressings, sanitary products, specialty papers, packaging or filter materials.

  • Patent number: 10905645
    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.

  • Patent number: 10800130
    Abstract: The invention relates to flexible PCM sheet materials having a high latent thermal energy storage density for the purpose of heat management. The flexible PCM sheet material includes a flexible supporting structure and phase-change-material elements arranged thereon separately in a specific geometry. The phase-change-material elements are geometrically defined structures composed of polymer-bound phase-change material. The flexible PCM sheet materials are characterized by a high latent heat storage capacity and optimized thermal conductivity, are dimensionally stable even in the event of temperature changes and after phase transitions, can be rolled, folded, wound, or cut to size without problems, and can be transported, stored, processed, or used in a single layer or in multiple layers.

  • Patent number: 10443153
    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.

  • Patent number: 10323138
    Abstract: The invention relates to a process for producing cellulosic shaped articles with stabilized inclusions in the form of a microfine dispersion of nonpolar organic compounds and mixtures by a dry-wet extrusion process. The shaped articles produced in this way exhibit by comparison with unmodified cellulose fibers a substantially increased storage capacity for nonpolar active substances. They are suitable in particular for use in textiles for clothing, industrial textiles, leisure, medicine and cosmetics. Potential functional effects imparted include the physical effect of heat storage and/or the uniform and finely meterable storage and release of nonpolar active substances and plant extracts from the interior of the fibers of the shaped articles. It is possible through a suitable choice of the nonpolar portion to produce by this process also fibers capable of absorbing liquid or gaseous nonpolar substances.

  • Patent number: 9243349
    Abstract: The invention relates to cellulosic moldings having very finely distributed zinc pigments after the dry-wet extrusion method. Cellulosic moldings formed in accordance with the inventive methods, compared to unmodified cellulose fibers, have a high degree of whiteness combined with greatly increased UV light absorption and a wash-resistant bactericidal effect, while at the same time having unrestricted textile processability. The cellulosic functional moldings produced according to the invention are particularly suited for use in textiles for clothing, technical textiles, recreation, medicine, and cosmetics.
