摘要： The invention relates to a method and a device for producing substantially endless fine threads from polymer solutions, especially spinning material for lyocell, wherein the spinning material is spun from at least one spinning hole or a spinning slot. The spun thread or film is drawn by high-speed accelerated gas flows using a Laval nozzle whose narrowest cross-section is located beneath the point where the spinning material exists. The threads are arranged on a strip in the form of a non-woven or are taken up in the form of a yarn and are subsequently separated in spinning baths by means of solvents.

摘要： An apparatus for delivering and depositing groups of continuous threads or filaments, which are conveyed by means of a gas flow and which are introduced substantially parallel into a passage having a corresponding cross-section is proposed, the gas flow accompanying the threads upon entering the upper part of the passage is accelerated to high speed and is then decelerated and the threads are deposited on a moving depositing surface. The gas flow delivering the threads flows at high speed through the passage preferably provided with parallel walls and then is decelerated by the suction of part of the gas in the lower passage area laterally through openings in the passage walls.

摘要： A reactor for highly viscous media with a horizontally oriented reactor casing having an inlet and an outlet in which a cage-like rotor is mounted in a rotary manner by means of stub shafts. To the cage-like rotor are fixed elements, e.g., rings, which are immersed in and thoroughly mix the media. A stripping rotor is provided coaxially with the cage-like rotor. Both rotors rotate within one another and mix and deliver the media and thereby form free surfaces. In addition, they also clean one another through a scraping action.

摘要： This invention relates to a process for carrying out continuous demonomerization and postpolymerization of Polyamide 6 melts and a reactor for carrying out this process. The reactor of this invention has a cylinder with a horizontal axis around which an interior rotor shaped like a cage rotates. The reactor can be partially filled with polymer melt. There is a multitude of elements along the periphery of the rotor which partly dip into the melt and serve to convey the melt through the reactor, generate new surfaces and mix and homogenize the melt as the polymer melt undergoes demonomerization and postpolymerization under vacuum.

摘要： Described are a process and an apparatus for the aftercondensation of polycondensates, wherein moist and amorphous polymer in a granular or powderous form is continuously introduced from above into a single reactor. The granulate flows downward under gravity, with a hot gas being caused to flow in counter-current relation thereto. The reactor is formed as a continuous shaft or column which has positioned in the upper portion thereof an agitating element acting to prevent agglutination of the granulate. The granulate is crystallized and pre-dried in the upper portion of the shaft or column. In a further (subsequent) portion of the shaft or column, drying and aftercondensation take place without separation from the remainder of the shaft or column.

摘要： The invention relates to a method and a devise for pulversing liquids using gas flows. According to the invention, the liquid is guided through an outlet into a pulverisation chamber and is pulverised in fine droplets. The liquid jet leaving the outlet of a liquid channel is accelerated by a laminar gas flow which is continuously accelerated by means of a Laval nozzle, until the increasing pressure inside the liquid jet and the decreasing pressure in the gas flow leads to the explosion of the liquid jet and to the formation of droplets.

摘要： An apparatus comprises a spinning head connected to a feeder for the melt, a spinneret assembly which is held in the spinning head and comprises a spinning bore and which spins a melt monofilament, a plate which is located below the spinning head and which comprises a Laval nozzle arranged in a fixed geometrical relationship. Between plate and spinning head a closed first space is formed provided with a supply of gas and below the plate a second space is provided. The throughput of the melt per spinning bore, the temperature of the melt and the pressure in the first and second spaces are adjusted in such a way that the spun melt monofilament after leaving the Laval nozzle before solidification thereof attains a hydrostatic pressure which is greater than the gas pressure surrounding it, such that the thread bursts and splits into a plurality of fine threads.

摘要： The invention relates to a spinneret for spinning threads from a spinning mass—in the form of a melt or solution of natural or synthetic origin—comprising a rotationally symmetrical spinneret. The rotationally symmetrical spinneret inner part is surrounded at least partially by a rotationally symmetrical outer part, wherein in the longitudinal direction between the spinneret inner part and outer part an insulating chamber is formed, in which a gas, preferably air, is received in order to form an insulating gas layer. The invention further relates to a spinning device for spinning threads from a spinning mass, comprising a spinneret part and a gas nozzle part arranged at a distance from the spinneret part. A plurality of spinnerets according to the invention are inserted in the spinneret part and project from the spinneret part, facing the gas nozzle part, and the gas nozzle part comprises a plurality of gas nozzles associated with the spinnerets. The gas nozzles are designed as acceleration nozzles for a gas flow that is conducted through the respective gas nozzle and encompasses the monofilaments. Said spinnerets are used in a method for producing spunbonded materials or yarns from polymers of natural or synthetic origin, in order to build up said materials or yarns from extremely fine threads having an average thread diameter of less than 1 μm. The threads from the individual spinnerets can also be collected using conventional winding mechanisms to form yarns on bobbins.
