    摘要: A porous fiber having sufficient chemical resistance to a variety of substances to be adsorbed, and having a large specific surface area and a large void percentage. The porous fiber provided by the present invention features a main fiber body formed of a high-density polyethylene having a melt flow rate of 0.3 to 20 g/10 minutes and numerous pores. The pores are formed by mixing the high-density polyethylene with a paraffin wax while they are melted, melt-spinning a fiber with an extruder at a draft ratio of 200 or less, stretching the fiber, heat-treating the stretched fiber, mechanically crimping it and then removing the paraffin wax. In the porous fiber, the main fiber body has a specific surface area of 20 m.sup.2 /g or more, the ratio of the pores to the main fiber body is 20% or more and the main fiber body has a size of not more than 50 denier.

    摘要: The rope of this invention comprises a plurality of strands each having a twisted reinforcing fiber bundle, thermosetting resin applied to the fiber bundle, and a thermoplastic resin cover enclosing the fiber bundle. Each strand in the rope is kept to substantially a round sectional shape by the twisted fiber bundle.The method for forming the rope comprises the steps of twisting the reinforcing fibers in such a manner that the tensile strength of the twisted fibers is not reduced to less than 50% of the fibers not twisted, applying an uncured thermosetting resin to the twisted fibers, covering the fibers with a molten thermoplastic resin, cooling the thermoplastic resin to cover the fibers with solidified thermoplastic resin and thereby forming a strand, forming a rope structure from a plurality of the strands, and heating the rope structure to cure the thermosetting resin applied on the fibers.
