摘要
Method for spinning fancy yarns (16) comprising the steps of: a) injecting continuously a bundle (3) of base fibres to a drafting train (1) of said bundle (3) of base fibres, b) when said bundle (3) of base fibres is continuously injected, injecting intermittently a bundle (10) of effect fibres to said same drafting train (1) to add intermittently said bundle (10) of effect fibres to said bundle (3) of base fibres, and each intermittent injection of effect fibres of step b) includes the steps of: bi) advancing a stretch of said bundle (10) of effect fibres to the drafting train (1) of said bundle (3) of base fibres, and bii) then, moving backwardly said stretch a preset length, said backward movement permitting the forced cutting or separation of a fragment of bundle (10) of effect fibres to be added to the bundle (3) of base fibres in said drafting train (1). The fancy yarn (16) manufactured by the method comprises a plurality of fragments of a bundle (10) of effect fibres added in a discontinuous way to a bundle (3) of base fibres. The formation of said fragments permits the fibres to be added as more compact groups to the bundle of base fibres, which enhances the effect of added fibres and also the quality of the obtained yarn.
