The invention relates to a method for producing, amongst other things, amino-acid and/or hydroxycarboxylic-acid metal chelates, a solvent-free mixture of at least one metal oxide, metal hydroxide, metal carbonate or oxalate, and the solid organic acid is subjected to intensive mechanical stress. According to the invention, this is done in that the reaction partners are introduced in particle form into a fluid stream of a fluid-bed countercurrent mill operating without grinding elements, wherein mechanical activation of at least one of the reaction partners is effected by collision processes within a reaction chamber formed in a region of the fluid stream, and a solid body reaction to form the metal chelate is triggered. The novel method operates very energy-efficiently and with a high specific yield. It leads to a product having compact particles in the small, single-digit micrometer range having a comparatively narrow particle sizc distribution and a large surface. The product is homogenous and very pure. Thermal loading or decomposition of the organic chelate ligands, in particular of the amino acids, is likewise avoided, as are contaminants from milling and grinding element abrasion.

An object of the present invention is to make it possible that a pyridine antibacterial/antifungal agent is dispersed stably in a liquid for appropriate impartation of the pyridine antibacterial/antifungal agent to fibers, and that when fibers are processed with the agent which is mixed with various other treating agents such as dyes and softeners, there is no negative influences on the process of the fibers for imparting antibacterial/antifungal properties. An antibacterial/antifungal properties-imparting agent contains a pyridine antibacterial/antifungal agent; a modified polysaccharide having reduced hydroxyl groups; and a wetting agent; but does not contain a surfactant. After applying the antibacterial/antifungal properties-imparting agent to fibers, the fibers undergo a heating process.
