ABSTRACT:
A synthetic pulp comprising a pulp fiber of a thermoplastic resin and, adhering to the surface thereof, a polypropylene glycol having a molecular weight of 200 to 10,000, preferably together with a phenolic antioxidant and/or a phosphorous acid ester type antioxidant, has an excellent hydrophilic property even in the dry state and a good wettability or rewettability. This pulp forms a good slurry without bubbling when thrown in water. When a mixture of this synthetic pulp and other hydrophilic short fiber is subjected to a heat-fusion treatment, a fibrous molded articles having an excellent hydrophilic property, a good wettability or rewettability and a high wet strength is obtained, and this fibrous molded article is especially valuable as an absorbent.
