- a multifilament yarn is used to twist a short-fiber staple fiber yarn or a second multi-filament yarn.
- air blasting texturing multiple multifilament yarns are connected to form a multi-component loop yarn, or staple fibers are mixed into a multifilament yarn and a mixed yarn is obtained.
- a single smooth multifilament yarn can also be turned into loop yarn by air-blast texturing. In all cases, the air techniques are only applied to multifilament yarns made from synthetic and natural man-made fibers.
- multifilament yarns consist of a plurality of individual continuous fibers or filaments.
- Air-treated multi-component yarns are made exclusively from multifilament yarns built up because one assumes that a reliable connection of the components, ie the multifilament yarns, can only be achieved if each component is opened by the air flow and the individual filaments of all components intertwine or intertwine.
