    Abstract: A nonwoven fabric is produced from a batt of staple fibers by passing the unneedled batt of staple fibers to at least two needling zones, each needling zone having a plurality of needles which move in a reciprocating motion having a first needling direction and a second needling direction, the needles in a first needling zone having barbs which catch staple fibers of the batt primarily when the needles move only in the first needling direction and the needles in a second needling zone having barbs which catch staple fibers of the batt when the needles move in both the first needling direction and the second needling direction.

    Abstract: A nonwoven textile fabric comprising a batt of nonwoven filaments and having at least a portion of the filaments extending outwardly from one face of the batt to form a raised pile. In one embodiment at least a portion of the filaments are fused together on one side of the batt forming a fused face, and the raised pile extends outwardly from the fused face. In another embodiment, the batt has a fused face on each side thereof and the raised pile extends outwardly from one of these fused faces. In still another embodiment, the batt has a single fused face and the raised pile extends outwardly from the side of the batt opposite the fused face. The textile fabrics are also disclosed with an adhesive and/or a backcoating layer on the side opposite the raised pile. Method and apparatus for the production of the nonwoven textile fabrics are also disclosed which employ needle punching the nonwoven batt with forked needles to provide the raised pile.

    Abstract translation: 一种非织造织物织物，其包含非织造长丝的毛层并且具有至少一部分长丝从所述絮垫的一个面向外延伸以形成隆起的绒头。 在一个实施例中，长丝的至少一部分在絮状物的一侧上熔合在一起形成熔化面，并且凸起的绒头从熔融的面向外延伸。 在另一个实施例中，絮垫在其每侧具有熔融面，并且凸起的绒头从这些熔接面之一向外延伸。 在另一个实施例中，絮垫具有单个熔化面，并且凸起的绒头从与熔融面相对的棉絮侧向外延伸。 纺织织物还在与隆起物相对的一侧上具有粘合剂和/或背涂层。 还公开了用于生产非织造织物织物的方法和设备，其采用针刺非织造絮垫用叉形针来提供凸起的绒头。

    Abstract: A nonwoven fabric is produced by forming a batt of fibers which are oriented primarily transverse relative to the direction of movement of the batt, stretching said batt longitudinally relative to the direction of movement of the batt, and needling the stretched batt. Also apparatus suitable for the production of the novel fabric is disclosed.

    Abstract: Nonwoven fabric is fed at a first rate into the bite between a first shredding element and a stationary working surface. The first shredding element has a plurality of projections which penetrate the fabric and at least substantially shred the fabric as the first shredding element is moved past the working surface at a second rate substantially greater than said first rate. The at least substantially shredded fabric then passes between the first shredding element and a second shredding element, the latter being driven at a third rate substantially different from said second rate to effect additional shredding and to separate the resulting staple fibers. A forced draft fan pulls air past the fabric as the fabric is being worked, to maintain the fabric temperature below the fusion temperature of the fibers.
