PURPOSE: To obtain the subject non-woven fabric radiating far IR light in a low temperature range and having a heat-insulating effect for human bodies by using a mixture of a polymer with particles having far IR light-radiating characteristics as a raw material. CONSTITUTION: This method for producing a far infrared light-radiating non- woven fabric comprises mixing a polymer as a base material with particles (preferably the particles of one or more inorganic compounds selected from alumina, zirconia and magnesia, having a purity of >=95% and an average particle diameter of 0.2-1.5 μm) having a far IR light-radiating characteristic comprising an average far IR light radiation rate of >=65% in a wavelength region of 4.5-30 μm, pelletizing the obtained raw material by the use of an extruder, processing the pelletized raw material into a film by the use of a processing machine, cutting the film with a shredder, and finally processing the obtained staple fibers into the non-woven fabric. The polymer is preferably PE, polystyrene, PP or a nylon. |
