Patent
Lenzing Ag | Date: 2016-11-10

The present invention relates to a dispersible nonwoven fabric comprising pulp and solvent spun cellulosic fibers, characterized in that the solvent spun cellulosic fibers are fibrillated. Furthermore the invention concerns the use of the fabric in dry wipes and wet wipes.


Patent
Lenzing Ag | Date: 2015-02-12

The present invention relates to a high-tenacity cellulosic regenerated fiber with an individual fiber titer of between 0.6 and 0.9 dtex and yarns and planar textile structures which contain regenerated fibers of this kind.


The present invention relates to a regenerated cellulosic fiber which contains an incorporated dye pigment and a fluorescent dye applied by overdying, the use of this fiber for the production of yarns and fabrics and a process for the production of these fibers. This fiber satisfies the demands of EN 471 in relation to luminance factor, the chromaticity coordinates and color fastness and possesses a light fastness (ISO 105-B02, process 2) of more than 5.


The present invention relates to a three-dimensional cellulosic molded body that has an optically detectable core/shell structure, the shell having a higher density and a lower crystallinity than the core, and the core having a sponge-like structure. The invention further relates to a method for producing this molded body as well as to its use, especially in the cosmetics and pharmaceutical industries.


The present invention relates to a phase-stable suspension of cellulose II in water, having a high water retention capacity and a cellulose concentration between 0.1 and 5.0% by weight, a method of its preparation, and its use.


The present invention relates to cellulose fibers with an enhanced metering capability, a process for the production of these and the use of these for the reinforcement of compound materials, in particular thermoplastic polymers.


Patent
Lenzing Ag | Date: 2014-06-13

The present invention relates to a method for the production of highly absorbent polysaccharide fibers which contain a mixture of cellulose and (13)-glucan as a fiber-forming substance, as well as to the highly absorbent fibers made thereby, and to their use.


Patent
Lenzing AG | Date: 2014-06-13

The present invention relates to a direct dissolving process for the production of polysaccharide fibers which contain (13)-glucan as a fiber-forming substance, with aqueous sodium hydroxide solution as a solvent, as well as to the fibers made thereby, and to their use.


The present invention relates to a method for the production of polysaccharide fibers which, as a fiber-forming substance, comprise a mixture of cellulose and (13)-glucan, as well as to the fibers made thereof and to their use.


Patent
Lenzing Ag | Date: 2014-04-10

The present invention relates to a method for the production of films made of polysaccharides which, as a fiber-forming substance, contain (13)-glucan, as well as to the films made thereof and to their use.
