<p>Vegetable fibres are treated in loose form with chlorine during mercerization, whereby they are curled. The chlorine may be introduced from an extraneous source, or may be derived from hypochlorous acid or sodium hypochlorite. In an example, jute fibres are stapled and treated with caustic soda solution, and chlorine is passed in slowly; the fibre is removed, hydro-extracted, neutralized with dilute acid and washed. The fibres may subsequently be treated with ammonium phosphate for fireproofing, and with softening or emulsifying agents and mineral oil, and with bleaching-agents.</p> |
