    摘要： A twisting machine (100) for producing artificial grass starting from a tape (BND).
    The twisting machine (100) comprises:
    (c1) a control unit (110) which exchanges information among the various appliances;
    (c2) an extrusion apparatus (120), suitable to produce a tape (BND) ;
    (c3) a storing unit (130) of the tape (BND) ; and
    (c4) a twisting unit (140) of the tape (BND) for producing the desired synthetic grass. The twisting machine (100) is characterized in that the storing unit (130) is able to store the tape (BND) coming directly from the extrusion apparatus (120), and is also able to feed, directly and at the same time, the tape (BND) to the twisting unit (140).

    摘要： A new fiber-forming method, and related apparatus, are taught in which extruded filaments of fiber-forming material are directed through a processing chamber that is defined by two parallel walls, at least one of which is instantaneously movable toward and away from the other wall; preferably both walls are instantaneously movable toward and away from one another. Movement means are connected to the at least one movable wall to provide instantaneous movement. In one embodiment, the movement means comprises biasing means for resiliently biasing the wall toward the other wall. Movement of the wall toward and away from the other wall is sufficiently easy and rapid that the wall will move away from the other wall in response to increases in pressure within the chamber but will be quickly returned to its original position by the biasing means upon resumption of the original pressure within the chamber. In another embodiment the movement means comprises oscillating means for oscillating the wall at a rapid rate. The invention also provides new nonwoven webs, which comprise a collected mass of fibers that includes fibers randomly interrupted by isolated fiber segments that comprise oriented polymer chains but differ in morphology from the main portion of the fiber.

    摘要： This invention pertains to variable denier filaments prepared from synthetic polymers having a glass transition temperature of at least 30°C and yarns made therefrom. The filaments have longer length slubs, which results in their use in fabrics desiring a variable texture and dyeing effects. The filaments are prepared by drawing at ambient temperature a feeder yarn having sufficient molecular orientation at carefully controlled draw ratios and in draw zones having a specified length.
