Abstract
In the production of multicolored yarn from differently colored filament bundles, the individual bundles may be texturized collectively. Then they are separated again into crimped part-threads 11.3 through 11.5 and are compacted individually in after-compacting means 8 before these part-threads are jointly compacted in a collective compacting means 9 and subsequently are wound up as a yarn 12 in a winding device 10.
Claims34
A method for producing a yarn from a plurality of part-threads wherein at least one physical characteristic of the part-threads is different so as to produce a desired visual effect in the produced yarn, comprising individually conveying each of the part-threads into a common texturizing device;
- conveying each of the individual part-threads separated from each other at least partially through the common texturizing device;
- joining the individual part-threads after said step of conveying the individual part-threads separated from each other;
- and jointly texturizing the joined part-threads with a texturizing element in the texturizing device.
An apparatus for producing a yarn from a plurality of individual part-threads wherein at least one physical characteristic of the part-threads is different so as to produce a desired visual effect in the produced yarn, said apparatus comprising a texturizing device having individual inlets defined therein for receiving the respective individual part-threads and individual heating and conveying ducts configured for conveying the individual part-threads separate from each other at least partially through said texturizing device, said texturizing device further comprising a texturizing element disposed to receive the part threads from said heating and conveying ducts and to jointly texturize the part-threads.
A continuous filament yarn comprising a plurality of part-threads wherein at least one physical characteristic of the part-threads is different so as to produce a desired visual effect in said yarn, said part-threads having been conveyed individually into a texturizing device and jointly texturized in a process wherein said part-threads were conveyed separated from each other through individual ducts in said texturizing device prior to being joined and jointly texturized by a texturizing element.
