摘要： The spinneret according to the invention is especially suitable for spinning cellulose solutions and has a die body which is essentially rotationally symmetrical having an inlet in its centre for cooling gas, an inlet for cellulose solutions, an annular deep-drawn spinning insert of precious metal with spinning holes wherein the spinning insert is designed pan-shaped in cross-section, and a baffle plate to deflect the cooling gas stream through the cellulose filaments which are extruded from the spinning holes, so that the cooling gas stream strikes the extruded cellulose filaments essentially at right angles. The spinning holes in the spinning insert are uniformly spaced from one another.

摘要： A process is disclosed for the preparation of a shapeable solution of cellulose in an aqueous tertiary amine-oxide from comminuted cellulose. The process includes introducing previously comminuted cellulose material into an aqueous solution of a tertiary amine-oxide to prepare an initial suspension, subjecting the initial suspension to high-consistency milling to further break-up the cellulose material to obtain a second suspension, and converting the second suspension into a shapeable solution of cellulose by heating under reduced pressure.

摘要： To produce a monoaxially stretched shaped article of polytetrafluoroethylene (PTFE), a pasty mass containing PTFE powder is continuously shaped to a shaped body, which is fed over a plurality of rollers or rolls, heated and stretched. The shaped body is heated to a temperature of between 327.degree. and 450.degree. C. prior to stretching strain, it is sintered simultaneously and is then stretched. This process allows for the production of a monoaxially stretched shaped article of PTFE which has strength values in the stretching direction of at least 500 N/mm.sup.2 and a delivery of between 1.80 and 2.30 g/cm.sup.3.

摘要： For the removal of water from dilute aqueous solution of NMMO, N-methylmorpholine or morpholine or mixtures thereof, the solution is subjected to reverse osmosis at a pressure in excess of the osmotic pressure and probably around 40 bar and a temperature of 25.degree. C. to 75.degree. C. to form a retentate containing the amines and a permeate which is practically free from the amines. The permeate can be used as process water while the retentate can be worked up to NMMO for reuse in the cellulose solubilization process.

摘要： For the production of a tubular woven fabric having a floats-including weave, by using a circular loom, at least two shuttles are moved through sheds formed by warp threads. The warp threads are guided through thread eyes of thread guiding organs and are lifted and lowered by the thread guiding organs to form the shed. In order to be able to produce tubular woven fabrics of different types of floats-including weaves, free warp threads, i.e., warp threads that are loosely guided through between thread guiding organs carrying neighboring warp threads, additionally run between warp threads guided by the thread guiding organs. These loose warp threads cross the opened shed approximately in the middle thereof and are lifted by a guide means arranged on at least one shuttle and, as the method proceeds, are lowered by a guide means arranged on at least one shuttle.

摘要： A method and processing facility for producing regenerated cellulosic fibers includes extruding a spinning solution into a coagulation bath which contains a salt and preferably an alkali to produce the fibers. The spinning solution may include cellulose dissolved in an aqueous solvent comprising NaOH and ZnO. The coagulation bath may have a pH-value of at least seven. The method may also include a continuous process of applying to the fibers in a never-dried state a crosslinking agent with two or more reactive groups and heating the fibers to a curing temperature while maintaining the never-dried condition to produce a reaction between the crosslinking agent and the cellulose of the fiber.
