    • A method of producing cellulose fibres impregnated with metal nanoparticles, particularly silver nanoparticles. The method comprises swelling cellulose fibres in an aqueous alkali solution (e.g. NaOH (aq)). The swollen cellulose fibres are removed from the aqueous alkali solution and mixed with an aqueous solution of a metal salt (e.g. AgNO3) and a polymer solution so as to impregnate the fibres with metal nanoparticles. The swollen cellulose fibres impregnated with metal nanoparticles are then removed from the solution. The invention further relates to the composition of cellulose fibres impregnated with metal nanoparticles and an absorbent material (e.g. wound dressing) comprising a blend of cellulose fibres impregnated with metal nanoparticles with at least one other type of fibre.
    • 一种生产浸渍有金属纳米颗粒,特别是银纳米颗粒的纤维素纤维的方法。 该方法包括在碱性水溶液(例如NaOH(水溶液))中溶胀纤维素纤维。 将溶胀的纤维素纤维从碱性水溶液中除去并与金属盐(例如AgNO 3)和聚合物溶液的水溶液混合,以便用金属纳米颗粒浸渍纤维。 然后从溶液中除去浸渍有金属纳米颗粒的溶胀纤维素纤维。 本发明还涉及浸渍有金属纳米颗粒的纤维素纤维的组合物和包含浸渍有金属纳米颗粒与至少一种其它类型纤维的纤维素纤维的共混物的吸收材料(例如伤口敷料)。
