BIOCIDE-FREE, PREWETTED SPONGE CLOTH

A biocide-free sponge cloth prewetted with a hygroscopically acting inorganic salt is provided. The spone cloth is based on regenerated cellulose which is mechanically reinforced with fibres and/or a web and includes a hygroscopically acting salt. The sponge cloth has an aw value of less than 0.80. On account of the low aw value, the sponge cloth has an antibacterial, bacteriostatic, fungicidal and/or fungistatic effect. The hygroscopically acting salt is preferably magnesium chloride. It can be combined with further inorganic salts, with low molecular weight, mono- or polyhydric alcohols, with sugars, sugar esters, mono- or polybasic carboxylic acids, esters of mono- or polybasic carboxylic acids and/or with hydrophilic polymers. The sponge cloth is preferably produced by the viscose process. 本发明描述了一种用吸湿作用的无机盐预润湿的基于再生纤维素的无杀菌剂的海绵布，其用纤维和/或网机械增强，并且包含吸湿活性盐，特征在于所述海绵布具有少于0.80的a值.由于低a值，该海绵布具有杀菌作用、抑菌作用、杀真菌作用和/或抑制真菌作用.该吸湿活性盐优选为氯化镁.其可以与其它的无机盐组合，与低分子量单-或多羟基醇组合，与糖，糖酯，单-或多元羧酸，单-或多元羧酸酯组合和/或与亲水聚合物组合。该海绵布优选通过粘胶法制备。
