    • A mat containing highly machine direction oriented (90% or greater), discontinuous reinforcement fibers, is produced on inclined wire or rotary paper making machinery. Fibers are first uniformly dispersed in an aqueous medium containing thickeners and wetting agents. In one embodiment, antifoaming agents are also added to prevent floating fibers which entangle and reduce orientation. Thermoplastic fibers or particles may also be included. Stock is brought into an open headbox in a flow pattern which allows the fibers to decelerate before approaching the porous suction belt (wire). As the fibers approach the suction belt, the fibers begin to turn and align in the streamline so as to present one end toward the suction wire. The leading ends of the fibers are gripped by the moving belt which drags the fibers out of the dispersion stock in a straight line. The porous mat produced may be dried and bonded through hot air, heat and/or pressure, or chemical binders. Stacks of such mats may be compressed partially to produce porous structures, or fully to produce
    • 在倾斜的线材或旋转造纸机械上生产包含高机械方向取向(90%或更大)的不连续增强纤维的垫。 纤维首先均匀分散在含有增稠剂和润湿剂的水性介质中。 在一个实施方案中,还加入消泡剂以防止缠结并降低取向的漂浮纤维。 也可以包括热塑性纤维或颗粒。 库存被带入流动模式的开放式流浆箱,其允许纤维在接近多孔吸入带(线)之前减速。 当纤维接近抽吸带时,纤维开始在流线中转动并对齐,以便将一端朝向吸力线。 纤维的前端被移动的带抓住,该带将纤维从分散料中直线拖出。 生产的多孔垫可以通过热空气,热和/或压力或化学粘合剂进行干燥和粘合。 这种垫的堆叠可以被部分压缩以产生多孔结构,或完全产生
