Abstract
A method for ring-spinning with pneumatic guiding and capturing includes steps of: respectively fixing a pneumatic guiding and capturing apparatus in front of each drawing system of a ring frame; twisting the ribbon-like strand outputted through a front roller nip to form a spinning strand, moving the spinning strand into a holder groove of a capturing holder; guiding ribbon-like strand edge fibers to closely contact with a spinning strand main body by negative pressure airflow in the holder groove; before the ribbon-like strand edge fibers enter an in-take opening, cohering the edge fibers with the spinning strand for being partly captured by the spinning strand stem; other un-captured edge fibers become spinning strand hairiness, which is then stretched and tightly wrapped onto the spinning strand stem by a negative pressure; the spinning strand is outputted from the holder groove outlet to get a high qualified spun yarn.
