Abstract: The present invention relates to a process for the manufacturing of composite materials from natural fibers and thermoplastic polymers. Examples of fibers are wood fibers originating from pulping processes known as refiner pulp (RMP),thermomechanical pulp (TMP) or chemi-thermomechanical pulp (CTMP),but the process can also be applied to other kinds of natural fiber containing raw materials. In the process according to the present invention, fibers are introduced from the blowline or the housing of a refiner into a flash tube dryer, separated from humid air in a cyclone, introduced into a compounder and mixed with at least one thermoplastic polymer and the product is subsequently pelletized. The process according to the present invention is advantageously run as a continuous process.
Abstract translation: 本发明涉及由天然纤维和热塑性聚合物制造复合材料的方法。 纤维的实例是源自称为精制浆（RMP），热机械浆（TMP）或化学热机械浆（CTMP）的制浆工艺的木质纤维，但是该工艺也可以应用于其他种类的含天然纤维的原材料。 在根据本发明的方法中，将纤维从吹管或精炼机的壳体引入到闪蒸管干燥器中，与旋风分离器中的潮湿空气分离，引入到混合器中并与至少一种热塑性聚合物混合，并将产物 随后造粒。 根据本发明的方法有利地作为连续过程来运行。
