PROBLEM TO BE SOLVED: To obtain an inorganic fine particle-containing yarn having fiber physical properties sufficient for processing, containing various inorganic fine particles, excellent in development ability of various functions of inorganic fine particles and to provide a method for producing the yarn. SOLUTION: This inorganic fine particle-containing yarn comprises inorganic fine particles having <=10μm average particle diameter and a fiber-forming polymer containing >=0.01 milliequivalent of any of polar groups of sulfonic group, carboxyl group and phosphate group. The yarn is produced by mixing the fiber-forming polymer containing >=0.01 milliequivalent/g with the inorganic fine particles having <=10μm average particle diameter and spinning. The yarn and a processed material of yarn in which the inorganic fine particles are uniformly dispersed in high concentration, excellent in developing ability of functions of inorganic fine particles and mechanical properties are provided. |
