ABSTRACT:
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 discovered.
