    • The invention relates to a sponge cloth based on cellulose and having an internal reinforcement, obtainable by the amine oxide process. In the process, a solution of cellulose in an aqueous amine oxide is first produced, which is then mixed with at least one pore former and fibers. The mixture is spread on a conveyor belt which is then guided through a coagulating bath comprised of a diluted aqueous amine oxide solution whose temperature is high enough such that the pore former melts and is dissolved out. Remaining amine oxide is washed out. After subsequent drying the sponge cloth layer is end-itemed. Contrary to the viscose process polymer degradation does not occur in the inventive process which results in a sponge cloth having an improved mechanical stability. A plastic net can replace the fiber reinforcement. The process is especially ecological and economical. The sponge cloth is highly water-absorbent and can be used for household or industrial purposes, especially for cleaning and decontaminating purposes.
    • 本发明涉及一种基于纤维素并具有可通过氧化胺方法获得的内部增强物的海绵布。 在此过程中,首先制备纤维素在氧化胺水溶液中的溶液,然后将其与至少一种成孔剂和纤维混合。 将混合物铺展在传送带上,然后将其引导通过由温度足够高的稀释的氧化胺水溶液组成的凝固浴,使得成孔剂熔化并溶出。 剩余的氧化胺被洗掉。 随后干燥之后,海绵布层是最终制成的。 与粘胶工艺相反,本发明方法中不会发生聚合物降解,这导致海绵布具有改进的机械稳定性。 塑料网可以代替纤维增强。 这个过程特别生态经济。 海绵布是高吸水性的,可用于家庭或工业用途,特别是用于清洁和净化目的。

    • Antimicrobial film based on biopolymers, in particular cellulose and/or protein, or uncoated or coated textile material, and also an antimicrobial sponge or an antimicrobial sponge cloth based on regenerated or precipitated cellulose are provided. The film, the sponge or the sponge cloth is impregnated or coated with at least one α-amino acid ester, the α-amino group of which is acylated with a fatty acid, or the corresponding hydrochloride, and the α-amino acid ester is bound covalently, optionally also ionically, to the film, the sponge or the sponge cloth. The acylated α-amino acid ester is preferably N-lauroyl-L-arginine ethyl ester monohydrochloride (LAECI), N-lauroyl-L-arginine methyl ester monohydrochloride (LAMCI) or N-lauroyl-L-lysine ethyl ester hydrochloride (LLECI). The film is preferably in the form of a flexible tube and is provided as casing for foods, especially sausage products.
