    • In a method for producing a bristle from thermoplastic polymers through injection molding, the molten polymer mass is injected under pressure into a bristle-molding channel of predetermined length having a predetermined cross-section along this length and the channel is vented during injection molding. To produce injection-molded bristles with excellent bending behavior, the magnitude of the injection pressure is adjusted in dependence on the cross-sectional extension of the bristle-molding channel such that a shear flow is generated with high core speed in the center of the molten polymer mass flow and large shearing effect due to wall friction of the molten polymer mass under distinct longitudinal orientation of the polymer molecules at least in the region of the molten polymer mass close to the wall, which is maintained along the channel wherein the channel is simultaneously vented along its length to support maintenance of the shear flow. A device for carrying out the method is also described.
    • 在通过注射成型从热塑性聚合物生产刷毛的方法中,将熔融聚合物物料在压力下注入具有沿着该长度具有预定横截面的预定长度的刷毛模制通道,并且在注塑期间通道通道。 为了生产具有优异弯曲行为的注射成型的刷毛,注射压力的大小根据刷毛模制通道的横截面伸长来调节,使得在熔融的中心处产生具有高芯速度的剪切流动 聚合物质量流动和由于熔融聚合物物质在聚合物分子的不同纵向取向下的壁摩擦的大剪切效应,至少在熔融聚合物物质接近壁的区域中,其沿通道同时保持 沿其长度排放以支持剪切流的维持。 还描述了用于执行该方法的装置。
