Production method for a filament yarn and corresponding device

Abstract

Method for the manufacture of filament yarns ( 10 ), with first capillaries ( 25 a ) in the centre of a spinning unit, whereby in each yarn type an identical make-up of the yarns from different material components pertains, for preference with several extruders, from which different materials ( 10 a , 10 b ) can be conducted to several spinning packages ( 1,2,3 ), with a distribution system ( 1,2 ) with a distribution plate and spinning nozzles ( 32 ) with indentations ( 12 c and 12 a respectively) in the spinning package for accommodating the materials, characterised by at least one first material ( 10 c ) for a first component of a first yarn type, which can be conducted into indentations which extend only over a part of a spinning package, and by a further material ( 10 b ) for further yarn types, capable of being introduced into at least one further indentation ( 12 b ), from where this material can be distributed over a larger or the whole extension of a distribution system ( 1,2,3 ) in order to pass to the spinning nozzles ( 32 ) concerned.

1 . A method for the manufacture of a filament yarn ( 10 ), or a fibril for a filament yarn respectively, by means of a spinning device, whereby at least two different liquified components or materials ( 10   a ,  10   b ) are conducted through several capillaries to a spinning capillary ( 25   a ,  25   c ) or spinning nozzle, and whereby at least two liquified components of materials ( 10   a ,  10   b ), from at least one first and one second source ( 14 - 16 ,  14 ′- 16 ″), are conducted to a distribution system with through passages, and further to a nozzle system ( 3 ), characterized in that at least two flows are combined from the material flows ( 10   a ,  10   b ) from n sources ( 14 - 16 / 14 ′- 16 ″), which are conducted to a distribution system, and are conducted to at least one through passage ( 12   a ,  13 ), while at least one further material flow ( 10   b ) from a further source ( 14 ″- 16 ″) is conducted separately to the distribution system ( 1 ), so that n material flows ( 10   a ,  10   b ) from n sources ( 14 - 16 ,  14 ″- 16 ″,  14 ′- 16 ′) are brought together in such a way that in the further processing only n−x different material flows are spun in through passages ( 12   a ,  12   c ) communicating with one another of a distribution system ( 2 ) and nozzle system to form filaments, and the filaments are in the final analysis composed only of n−x different materials or material mixtures respectively, with 1≦x<n−1 and n≧3, whereby n, x are whole numbers ( FIG. 1   d ).
