摘要:
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.

A backwash filter, in particular for highly viscous media, comprising a filter body (2) provided in a casing (1) and forming a cylinder jacket, wherein the casing (1) and the filter body (2) are rotatable about the axis of the filter body (2) relative to one another and wherein the filter body (2) separates a medium inflow space (14) from a medium outflow space (16), and comprising a flushing agent discharge channel (10) extending along a generatrix of the filter body (2), which flushing agent discharge channel (10) is movable relative to the filter body (2) and can be brought into flow connection with the filter body (2) across the entire length thereof and across the entire circumference thereof, with the formation of a stream of flushing agent flowing into the flushing agent discharge channel (10), is characterized, for increasing the efficiency of backwashing and of the throughput as well as for protection of the filter material, in that the flow connection always occurs only across a portion of the longitudinal extension (20) of a generatrix of the filter body (2).
摘要:
The objective of this invention is to enable the production of colored shaped flame retardant cellulosic articles such as fibers and to use them to produce fabrics and similar items simply and at lower cost than if they were colored by dyeing after production. A product has been invented that is a fiber which is colored using an included pigment during its manufacture.

摘要:
A device for producing Lyocell fibers which are extruded from a cellulose solution of water, cellulose and tertiary amine oxide in a spinning head (25). The cellulose solution is obtained in a number of process steps directly from the cellulose (3, 4) or with the formation of a cellulose suspension. Since the degree of polymerization decreases in the course of processing the cellulose through to its extrusion in the cellulose solution, with the processing of celluloses with a low degree of polymerization there is the risk that the endless molded bodies (2) extruded in the spinning head (25) exhibit defective quality. In order to also be able to process celluloses (3, 4) with a low degree of polymerization without having to accept reduced quality, according to the invention, the residence time of the cellulose from its introduction into the device (1) through to the extrusion of the cellulose (3, 4) in the cellulose solution is set in dependence of the degree of polymerization of the cellulose, of the cellulose suspension and/or of the cellulose solution.
摘要:
A moisture wicking fabric has one side comprised substantially entirely of inherently hydrophobic fibers such as polyester or polypropylene and the other side comprised of a mixture of hydrophobic fibers such as polyester or polypropylene and hydrophilic fibers, particularly cellulosic fibers such as cotton, lyocell and viscose rayon. A garment can be formed from such a moisture wicking fabric, for example by the whole garment knitting method, the side comprised of the mixture of fibers being the external side of the garment.
摘要:
The invention concerns a Lyocell fiber, containing a material selected from the group consisting of pearl powder, ground nacre and mixtures thereof. For the manufacture of the fiber according to the invention, a process is used comprising the steps of manufacturing a spinning solution of cellulose in an aqueous tertiary amine oxide, preferably N-methylmorpholine-N-oxide (NMMO) spinning the spinning solution to fibers, and being characterized in that a material selected from the group consisting of pearl powder, ground nacre and mixtures thereof is admixed to the spinning solution and/or to a precursor thereof.
摘要:
The present invention relates to polyolefin compositions comprising man-made cellulose fibers of very high modulus to improve the mechanical performance of said compositions while retaining a low density. The present invention further relates to a melt mixing process with controlled shear intensity and energy input especially suitable for the production of said compositions.
摘要:
The invention relates to a process for producing xylo-oligosaccharides, comprising the steps of cold caustic extraction (CCE) of a pulp obtained by a cooking process; purifying at least a portion of the press liquor forming in the cold caustic extraction stage using a membrane separation process, preferably nano- or ultrafiltration; obtaining the xylans from at least a portion of the retentate of the membrane separation process; processing at least a portion of the xylans obtained into xylo-oligosaccharides.
摘要:
The present invention relates to Lyocell staple fiber consisting of a plurality of cut filaments, which is characterized in that at least part of said cut filaments exhibit an overall cross-sectional shape which is a bi- or multi-filar cross-sectional shape resulting from notionally partially overlapping two or more fiber cross-sectional shapes.
