Abstract: A process for producing a cellulosic functional fiber having high ion exchange capacity, a cellulosic functional fiber produced by said process, a textile product comprising said cellulosic functional fiber, and a garment or piece of furniture comprising said cellulosic functional fiber and/or said textile product. The cellulosic functional fiber produced is characterized in that it comprises an extracted plant material with polymer-bound uronic acids contained therein.

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.

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.

Abstract: The invention relates to a method for the production of cellulose shaped bodies according to the dry-wet extrusion method (Lyocell method) with high degree of whiteness and bioactive action for use in the textile sector and paper production. In the context of the invention, the term “bioactive” refers to antimicrobial efficacy, based on the antibacterial action of the element silver, which is used as nanoscale reagent for increasing the efficacy thereof. The chemically inert and, at the same time, bactericidal effect is used in the production of sports and leisure clothing with a high degree of whiteness and papers with a long shelf life. Use is possible in the medical sector, for example, for wound dressings, textiles for hospitals, and in the filter and packaging industry.

Abstract: The invention relates to a process for chemical marking and identification of information in polymers and additives, such as ageing additives, thermal stabilizer additives, light stabilizer additives, plasticizer additives or flame retardant additives and dyes and other high-value additives. The marking is effected by the use of defined atomic masses in the form of isotopes of suitable elements in chemical compounds which are incorporated into the polymer matrix and anchored during the production. The result is a chemical code which can be recalled over the entire product life without adversely affecting the properties of the polymer through high concentrations of extraneous substances. It is possible by this process to trace back the origin of a polymer, to detect possible mixtures with chemically identical products from other manufacturers, or to clarify at a later stage whether an additive has been added in the concentration specified.

Abstract: The invention stabilizes spinning solutions used to produce cellulose composite molded bodies incorporating functional materials by the dry-wet extrusion method. The invention incorporates active materials detrimentally affecting the spinning process and materials which are unstable in the cellulose spinning solution, using separate active material and cellulose streams. The active material stream is produced, stabilized and stored separately and mixed with the cellulose stream directly before the forming apparatus, for example, a spinning bar. The active material stream includes amine oxide, functional materials, additives and water. The cellulose stream includes cellulose in amine oxide. The inventive method avoids heat build-up in the moulding or spinning solution, produces cellulose molded bodies with an adequately high degree of polymerisation and excellent functional properties and restricts the decomposition of the amine oxide.

Abstract: Textiles and also dishes and other household implements which are cleaned in laundry machines or dish washing machines can be afforded protection from an increasing colonization by bacteria when the textiles or the dishes are washed together with a microbicidal repository including a solid fiber composite of ion-exchanger particles loaded with silver ions, and a cellulose matrix.
