<p>PURPOSE:To obtain treated wool having excellent chemical reactivity, free from color and odor, and suitable as an adsorbent for heavy metals, etc., by immersing wool, etc. in an aqueous solution containing oxidizing agent, etc., heating under pressure in a pressure vessel, and discharging into low-pressure atmosphere thereby effecting the expansion of the wool. CONSTITUTION:Wool, etc. are immersed in an aqueous solution containing an oxidizing agent (e.g. performic acid), a reducing agent (e.g. thioglycolic acid), a surface-active agent (e.g. sodium laurylsulfate), an alcohol, an acid or an alkali. The treated wook, etc. are dehydrated, optionally washed with water, and heat-treated under pressure (>=2kg/cm<2>G, pref. 4-6kg/cm<2>G) with saturated steam in a pressure vessel, and discharged rapidly into a low-pressure atmosphere to effect the expansion of the wool, etc.</p> |
