High density polyethylene (HDPE) special resin for polyethylene (PE) /polypropylene (PP) bicomponent fiber, grade 1508S, was developed with high content of 1-butene as a comonomer. The resin had relatively low density and crystallinity and flexible molecular chain, and consequently the good flexibility of its non-woven fiber products. The grade 1508S, as the skin layer of PE/PP fibers, had a relatively low initial melting temperature, which could reduce fiber thermal bonding processing temperature, and therefore reduce energy consumption. The non-woven fabric produced with 1508S/PP composite fiber had primary skin contact irritation index of zero, which met the hygienic requirements.
