摘要： This invention relates to processes for the production of mono- and multifilaments and also staple fibers of multifilaments based on polyarylene sulfides, preferably substantially linear polyarylene sulfides and, more preferably, substantially linear poly-p-phenylene sulfide by melt spinning, multistage stretching and optionally crimping and setting.As a result of the treatment by blowing of air onto the stabilized spun filaments in the first stretching stages at temperatures .ltoreq.100.degree. C. (preferably in stretching baths, more particularly in boiling water), the chain molecules are oriented; the orientation and crystallinity required for high strengths is achieved by afterstretching (in hot air) at elevated temperature. The residence times in the first stage required for effective stretching in accordance with the invention can only be varied within relatively narrow limits in order subsequently to achieve the calculated orientations and effects, particularly high strengths, crystallinities and densities. Overly long residence times at temperatures above 100.degree. C. result in elongation of the material with no additional orientation and hence with an inadequate increase in strength.To increase crystallinity and strength in the production of mono- and multifilaments, multistage stretching may be followed by a thermal aftertreatment; in the staple fiber process, the material is additionally crimped, set (in the absence of tension) and cut. Where an aerodynamic crimping nozzle is used, as is preferably the case, stretching has to be carried out in accordance with the invention in such a way that the fibers are left with sufficiently high shrinkage which is important for crimping and subsequent processing. Crimping is improved by setting in the absence of tension. Relatively high-tensile fibers with sufficiently high residual crimping for subsequent processing are obtained.Textile-denier fibers (up to about 20 dtex) having hitherto unknown strengths of >6 cN/dtex, preferably >6.2 cN/dtex and, more preferably, >6.4 cN/dtex are claimed.

摘要： The polymer granular melt (1) is whirled out of a rotating nozzle head (6) through a plurality of exit holes (24) with fibre formation (32) and the fibres formed (9) are deposited on a collecting surface (12) in web form (15). This polymer melt is introduced into the nozzle head (6) under a preliminary pressure of 1 bar to 200 bar, preferably 1 bar to 50 bar. Furthermore, the fibres (32) are deflected by a high-speed gas stream (7, 8) in a radial direction at a radial distance of 10 mm to 200 mm from the exit holes (24) and, in the course of being deflected, are simultaneously drawn and stretched. The melt streams (32) exiting from the exit holes (24) can be additionally drawn by gas streams (26, 34) exiting in the vicinity of the exit holes (24) at the nozzle head (6) with a predominantly radial component before coming under the influence of the axial deflecting gas stream (7, 8).

摘要： Filaments of a molten material issue from a plurality of openings in a heated melt crucible and are further fiberized in a draw nozzle by means of a blowing medium. The diameter of the outlet openings (3) at the base of the melt crucible (1) is very small and is 0.2 to 1.5 mm, so that very fine primary filaments (12) are already formed at this point. These primary filaments are grasped by a very turbulent current at the entrance of the draw nozzle (5). The transverse component of the current decreasing in favor of the longitudinal component as the axial distance from the outlet openings (3) increases. The draw nozzle also has an inlet portion, which has a sharp outer edge and widens in the direction of flow, so that air blows against the primary filaments at a high speed and they are exposed to a strong pressure gradient in the longitudinal direction before entering the inlet portion. In the draw nozzle the primary filaments which are themselves already very thin are drawn out further until they have the required final diameter. For this purpose a zone is provided in the interior of the nozzle, following the inlet portion, in which zone the rate of flow of the blowing medium is 400 m/s to 600 m/s at a pressure of between 0.1 and 0.4 bar. By means of this device very fine mineral fibres with a substantially uniform fibre diameter of between 0.1 .mu.m and 5 .mu.m can be produced.

摘要： The streams of melt issuing from the melt outlet apertures (18) at the bottom of a melting crucible (14) are broken up into fibers in a drawing nozzle by means of a blast medium directed substantially parallel to the streams of melt. The blast medium is produced by a pressure gradient in the drawing nozzle and sucked in at the drawing nozzle inlet (7). In the drawing nozzle (16), the flow velocity is reduced in a downstream diffuser after the drawing process. The blast medium is supplied in the form of a hot gas between the underside of the crucible and the top edge (15) of the drawing nozzle from opposite broadsides of the melt distributor (14) in excess to the total quantity of gas stream sucked in at the drawing nozzle inlet (7). The hot gas consists of a mixture of combustion gases and air and is at a temperature from 600.degree. C. to 1500.degree. C., preferably from 800.degree. C. to 1400.degree. C. The flow velocity of the hot gas is adjusted to a value below 100 m/s, preferably 50 m/s, in the region (13) between the drawing nozzle (16) and the melt distributor (14). Gas burners (1) provided for producing the hot gas are arranged with their combustion chambers (3) situated laterally between the melt distributor (14) and the top edge (15) of the debiteuse. The combustion chambers (3) are connected by bores (6) to air chambers which are under an excess pressure. In the combustion chambers (3), the combustion gases are homogeneously mixed with the air introduced.
