摘要： Anti-microbial lyocell fibres incorporate an anti-microbial composition which comprises a silver compound deposited on a support material in the form of porous particles having an extended surface area and comprising an oxidic material which is essentially insoluble in water and incapable of forming hydrates. A preferred composition is silver chloride on titanium dioxide particles. The anti-microbial effect is durable to processing and the fibres are not adversely discoloured. Low concentrations of the anti-microbial composition of below 0.1 percent by weight on weight of cellulose may be used. In the process of making the fibres, the anti-microbial composition preferably is added to the pasty pre-mix of the spinning solution.
摘要翻译：抗微生物溶胞酶纤维包含抗微生物组合物，其包含以多孔颗粒形式沉积在支撑材料上的银化合物，其具有延伸的表面积并且包含基本上不溶于水并且不能形成水合物的氧化物质。优选的组合物是二氧化钛颗粒上的氯化银。抗微生物效果对于加工是耐用的，并且纤维不会被不利地变色。可以使用低浓度的抗微生物组合物低于纤维素重量的0.1重量％。在制造纤维的过程中，优选将抗微生物组合物加入到纺丝溶液的糊状预混物中。
