Abstract

A halogen group solvent comprising a mixed solvent consisting essentially of bromochloromethane and/or 1,2-dichloroethylene and a co-solvent, wherein the co-solvent is at least one member selected from the group consisting of carbon dioxide, sulfur hexafluoride, difluorochloromethane, 1,1,1,2-tetrafluoroethane, etc., and the content of said co-solvent in the mixed solvent is 3 to 65% by weight; a polyolefin solution using the solvent; and a process for producing a three-dimensional fiber of a polyolefin using the solution.
