摘要： Maleic anhydride-grafted HDPE fibers are disclosed. The processing of LLDPE and fibers is enhanced by including HDPE or LLDPE which has been grafted with maleic anhydride to obtain succinic acid or anhydride groups along the linear polyethylene chain in the fiber feed stock. The fibers are formed by extruding molten LLDPE containing the grafted HDPE or LLDPE through an orifice to form a thin fluid stream, melt drawing the thin fluid stream, and quenching the melt drawn thin fluid stream to form a fine denier strand. Biconstituent fibers of LLDPE and grafted HDPE or LLDPE, mixtures of such fibers with other fibers such as polyester, and woven and non-woven fabrics made from such fibers and fiber blends are also disclosed.
摘要翻译： 公开了马来酸酐接枝的HDPE纤维。 通过包括用马来酸酐接枝的HDPE或LLDPE来提高LLDPE和纤维的加工，以获得沿着纤维原料中的线性聚乙烯链的琥珀酸或酸酐基团。 纤维通过通过孔口挤出含有接枝的HDPE或LLDPE的熔融LLDPE而形成，以形成薄的流体流，熔化拉伸薄的流体流，并淬火熔融拉伸的薄流体流以形成细旦尼尔链。 还公开了LLDPE和接枝HDPE或LLDPE的双成分纤维，这种纤维与其它纤维如聚酯的混合物，以及由这种纤维和纤维共混物制成的织造和非织造织物。

摘要： Maleic anhydride-grafted HDPE fibers are disclosed. The processing of LLDPE and fibers is enchanced by including HDPE or LLDPE which has been grafted with maleic anhydride to obtain succinic acid or anhydride groups along the linear polyethylene chain in the fiber feed stock. The fibers are formed by extruding molten LLDPE containing the grafted HDPE or LLDPE through an orifice to form a thin fluid stream, melt drawing the thin fluid stream, and quenching the melt drawn thin fluid stream to form a fine denier strand. Biconstituent fibers of LLDPE and grafted HDPE or LLDPE, mixtures of such fibers with other fibers such as polyester, and woven and non-woven fabrics made from such fibers and fiber blends are also disclosed.
