摘要： 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.

摘要： To produce a mock yarn which is similar in appearance to a true yarn with respect to the ability to discern the components of the mock yarn after the twist has been imparted to the mock yarn, the rovings or slubbings forming the mock yarn, after drafting separately but parallel to one another in a drafting frame, are subjected separately to condensing and compaction by suction rollers or belts provided with rows of perforations. Thus compacted and condensed rovings are then combined, twisted and wound up as mock yarns. A core thread can be introduced into each roving or into at least one of the rovings upstream of the last pair of drafting rolls or immediately upstream of the condensing unit for a core mock yarn.

摘要： A spinning machine having a drafting frame, a condensing unit at the downstream side of the drafting frame and a spinning station for winding up the yarn and imparting twist to the roving in forming the yarn. The condensing unit comprises a disk-shaped suction rotor oriented in a plane tangent to the output rollers of the drafting frame. A limited compaction zone is formed by a shield within a suction rotor and designed to apply suction only to a limited portion of the perforated periphery thereof. The pressing roller bears against the suction rotor at the downstream side of the compaction zone.

摘要： A process for using recycled waste cotton material to produce a textile product is provided. The process can include collecting different categories of waste cotton material from a variety of textile formation processes. The process can also include selecting specific categories of waste cotton material to be blended together depending on the textile product to be produced. In the process, sequence of cleaning, opening and blending processing steps can be selected to be used in making a yarn depending on the textile product to be produced. The selected specific categories of waste cotton material can be cleaned, opened and blended into blended cotton fibers. The blended cotton fibers can then be processed into the textile product to be produced. Thus, a textile product can be provided that includes yarn that can have at least three different categories of waste cotton material that are from textile formation processes.
