PURPOSE:To provide the subject composition compounded with silica particles and inactive inorganic particles having specific particle sizes, respectively, and capable of being used for the production of films or fibers having lubricity, shaving resistance, winding characteristics, etc. CONSTITUTION:The objective composition compounded with (A) silica particles having a D1/D2 ratio of >=2 between a particle diameter (D1mmu) measured by a dynamic light-scattering method and a particle diameter (D2 mmu) measured by a nitrogen gas adsorption method, having the D1 of 60-600mmu. having a thickness of 41-100mmu on the observation using an electron microscope, and having a linear or branched shape, and (B) inactive inorganic particles such as silicon oxide, kaolin, calcium carbonate or titanium oxide particles having an average particle diameter of 10-500mmu. |
