Abstract

PURPOSE:To obtain the titled fiber having high adsorbing ability, by blending an aqueous solution of an alkali metallic salt of alginic acid with a powdery adsorbent, precipitating the blend in an alcohol/water mixed solvent in a fibrous state and immersing the fibrous substance in an aqueous solution of a specific metallic salt. CONSTITUTION:An alkali metallic salt of alginic acid such as sodium alginate is dissolved in water to give a viscous aqueous solution. Then the aqueous solution is blended with a powdery adsorbent such as active carbon or zeolite to form a uniform mixture and further the mixture is precipitated in a fibrous state in a mixed solvent having a composition consisting of 50-95vol.% alcohol and 50-5vol.% water in an amount corresponding that of the alcohol. Then the precipitated fibrous substance is immersed in an aqueous solution containing a metallic salt such as calcium chloride of two or more valence and the alkali metallic salt of alginic acid is converted into a water-insoluble metallic salt of alginic acid to give the aimed fiber containing a powdery adsorbent.
