Abstract (en)
[origin: ES8601343A1] A sliver (102), is drafted to yarn count in a drafting system (101) and fed to a false-twist unit (106) at a width of 10-19 mm. As a result of this width the sliver leaving the output rollers (105) is divided into a yarn core (119) twisted by the false-twist unit (117) and peripheral fibres which are picked up by (119) in the sunction channel (115). The leading ends of these fibres are enqagedin the narrowest part of (115) by the rotating yarn core (119) and wrapped around (119) in the same direction, but at a considerably greater pitch, until the trailing ends of the peripheral fibres are tied into (119) in the spinning triangle. On leaving the false-twist unit (108) the twist in (119) is neutralised and the twist in the sheath fibres is changed from S to Z, as a result of which EPAB- EP-131170 B A sliver (102), is drafted to yarn count in a drafting system (101) and fed to a false-twist unit (106) at a width of 10-19 mm. As a result of this width the sliver leaving the output rollers (105) is divided into a yarn core (119) twisted by the false-twist unit (117) and peripheral fibres which are picked up by (119) in the sunction channel (115). The leading ends of these fibres are enqagedin the narrowest part of (115) by the rotatinq yarn core (119) and wrapped around (119) in the same direction, but at a considerably greater pitch, until the trailing ends of the peripheral fibres are tied into (119) in the spinning trianqle. On leaving the false-twist unit (108) the stwist in (119) is neutralised and the twist in the sheath fibres is changed from S to Z, as a result of which (119) is held together.
