Problems solved by technology

However, in the case of a defined running surface of the still deformable yarn material, specific shape-changing operations can only be implemented by means of shear stresses
Therefore, when producing very fine yarns in the range of about and below 1 μm, the yield is substantially lower

Embodiment Construction

[0022] figure 1 with 2 The represented spinning device has a spinning nozzle part 28 in which a plurality of melt channels 14 are arranged, the above-mentioned melt channels being provided by means of a filter 25 and a perforated plate 26 for dispensing in the melt or In the case of a solution, the supplied melt or solution is purified. The melt channels continue into spinning nozzles or spinning nozzle sockets 23 , only three rows of spinning nozzle sockets 23 are shown here. A plurality of spinning nozzle connectors 23 can be arranged very perfectly one behind the other in the direction of progression of the arrow 50 .

[0023] The lower plate-shaped region of the spinning nozzle section is accommodated in a gas nozzle section 27 comprising a frame-like piping 34 and a plate-like section 35 in which three rows of respectively offset Laval nozzles 36 are arranged , the three rows of Laval nozzles 36 correspond to the rows of spinning nozzle pipe joints 23 . The piping por...

Abstract

A spinning apparatus for producing fine threads by splicing, which comprises a plurality of protruding spinneret jets disposed in a spinneret jet portion and having spinning orifices from which the spinning dopes exit as monofils and having a plurality of acceleration jets, in particular Laval jets, whose cross section reduces, only to widen downstream of the smallest cross section, which are assigned to the spinning orifices is proposed to be provided with means for feeding gas streams which surround the monofils and are accelerated by the acceleration jets. The acceleration jet, in an at least partially plate-shaped gas jet portion, is constructed as a funnel-shaped depression into which the spinneret jet reaches to form gas flow channels. Means for relative displacement of the gas jet part and of the spinneret jet part relative to one another are provided such that the flow cross section of the gas flow channels is alterable and / or the position of the smallest cross section of the acceleration jets is adjustable in relation to the spinning orifices.

Description

[0001] The present invention is a divisional application with the application number 200680054531.2 with the application date of October 23, 2006 and the name "spinning device for producing spun yarn by splitting method". technical field [0002] The invention relates to a spinning device for producing spun yarns by splitting according to the preamble of the main claim. Background technique [0003] Fine yarns in the range below 1 micrometer (μm) can be produced by splitting a fiber-forming fluid stream as a melt, a solution or generally as a liquid which substantially solidifies, as in DE 199 29 709 and DE 199 29 709 and DE 100 65 859 as described. The mechanism of yarn formation differs substantially from all currently known spinning methods in which the spinning material is taken up from a spinning nozzle by means of a winding device to form a yarn, or in spinning In the case of the viscose method, a force is exerted on the yarn by means of an accompanying air flow, and ...
