Abstract
(EN)
A composite yarn (2), an apparatus and a method preparing thereof. The composite yarn includes wrapping fibers (19) and a central yarn (18) that is formed by a first body yarn (16a) and a second body yarn (16b), wherein a portion of the wrapping fibers(19) are combined with the central yarn (18) in at least one of the following states: a first state, a portion of the wrapping fibers (19) wrap around the first body yarn (16a) or the second body yarn (16b); a second state, a portion of the wrapping fibers (19) wrap around the first body yarn (16a) and the second body yarn (16b) respectively at the same time; a third state, a portion of the wrapping fibers (19) wrap around the central yarn (18). The composite yarn disclosure has low twist factor and high strength, which solves the problem of severe strength loss associated with low twist factors existing in conventional low-twist techniques.
(FR)
L'invention concerne un fil composite (2), un appareil et un procédé de préparation associé. Le fil composite comprend des fibres d'enveloppement (19) et un fil central (18) qui est formé par un premier fil de corps (16a) et un second fil de corps (16b), une partie des fibres d'enveloppement (19) étant associées au fil central (18) dans au moins l'un des états suivants : un premier état, une partie des fibres d'enveloppement (19) s'enroulent autour du premier fil de corps (16a) ou du second fil de corps (16b) ; un second état, une partie des fibres d'enveloppement (19) s'enroulent autour du premier fil de corps (16a) et du second fil de corps (16b) respectivement en même temps ; un troisième état, une partie des fibres d'enveloppement (19) s'enroulent autour du fil central (18). La présente invention relative au fil composite présente un faible facteur de torsion et une résistance élevée, ce qui résout le problème de perte de résistance grave associée à de faibles facteurs de torsion existant dans des techniques classiques à faible torsion.
