Filament Spinning: After heating the polymer, the
melt is spun to endless yarn (filament) via spin packs.
The yarn is drawn and taken up. Saurer Brands:
Barmag, Neumag
Texturing: Mechanical or thermal processing of
filament to achieve properties similar to those of natural
fibers; mainly for textile applications. Saurer Brand:
Barmag.
Twisting: Twisting of one or several yarns into a ply
yarn. This can be done with filament as well as with
staple yarns. Saurer Brands: Allma, Volkmann
Ring spinning: By drafting and twisting, staples are
spun into ring yarn. Process is always followed by
winding. Saurer Brand: Zinser
Winding: The ring yarn is winded from the cops to
large bobbins. Thereby is quality check is executed.
Saurer Brand: Schlafhorst
Rotor spinning: Also called open-end spinning; with
suction, the staples are drawn to a rotor and thereby
spun to a rotor yarn. Saurer Brand: Schlafhorst
Chemical staple fiber plants: Process analog to
filament spinning, but after the spinning, staples of
defined length are cut. These staple serve as input
material for the ring or rotor spinning process. Saurer
Brand: Neumag
Nonwovens: The filaments or staples which build the
fabric are bonded with thermal, chemical, or mechanical
forces. There is no weaving/knitting process. Saurer
Brand: Neumag
