    • A colored long-fiber-reinforced polyolefin structure with a length ≧3 mm, which comprises from 0.1 to 90% by weight of at least one polyolefin, from 0.1 to 50% by weight of at least one polyamide, from 0.1 to 15% by weight of at least one modified polyolefin, from 5.0 to 75% by weight of at least one reinforcing fiber, and from 0.1 to 5.0% by weight of at least one dye and/or pigment. The present invention further relates to a process for producing a colored long-fiber-reinforced polyolefin structure, wherein fiber bundles are passed throught a flat die which has been charged with a melt made from polyolefin, polyamide, modified polyolefin and dye and/or pigment, the immersed fiber bundles are passed through a shaping die, the fiber bundles are cooled, and the fiber bundles are cut perpendicular to their running direction to give the length of the structure. The present invention relates to a molded product made from a colored long-fiber-reinforced polyolefin structure and produced by injection molding, extrusion, blow molding or plastic compression molding. The present invention also relates to the use of a colored long-fiber-reinforced polyolefin structure for producing colored moldings for the interior or exterior of motor vehicles.
    • 长度> = 3mm的有色长纤维增强聚烯烃结构,其包含0.1-90重量%的至少一种聚烯烃,0.1-50重量%的至少一种聚酰胺,0.1- 15重量% 的至少一种改性聚烯烃,5.0-75重量%的至少一种增强纤维和0.1-5.0重量%的至少一种染料和/或颜料。 本发明还涉及一种生产着色长纤维增强聚烯烃结构体的方法,其中纤维束通过一个扁平模具,该平板模具装有由聚烯烃,聚酰胺,改性聚烯烃和染料和/或颜料制成的熔体 将浸渍的纤维束通过成形模,将纤维束冷却,将纤维束垂直于其运行方向切割,得到结构的长度。 本发明涉及一种由彩色长纤维增强聚烯烃结构制成并通过注射成型,挤出,吹塑或塑性压缩成型制成的成型品。 本发明还涉及着色长纤维增强聚烯烃结构用于制造汽车内部或外部的着色模制品的用途。
