    • 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。

    • A cellulose sponge cloth based containing a net or grid as internal reinforcement is provided, with the sponge cloth further including a uniform distribution of fibers and/or durably softening polymers that are not water-leachable. The sponge cloth is produced by the viscose process by mixing with the fibers and/or the softening polymers and the pore former with cellulose xanthate and forming the resulting sponge cloth raw material into a thin layer. The grid or net is placed onto this layer, followed by a further layer of the sponge cloth raw material. Alkaline or acidic coagulation and regeneration baths and optional wash baths are used to dissolve the pore former out of the sponge cloth and regenerate the cellulose from the cellulose xanthate. The sponge cloth is bend-resistant, it does not break in the dry state. The sponge cloth is envisioned for cleaning and decontamination in industry and the home.
    • 提供了一种含有作为内部加强件的网或网格的纤维素海绵布,其中海绵布还包括均匀分布的纤维和/或耐久地软化不可水浸的聚合物。 通过与纤维和/或软化聚合物和成孔剂与纤维素黄原酸酯混合并将所得海绵布原料混合成薄层,通过粘胶工艺生产海绵布。 将网格或网放置在该层上,然后再铺设一层海绵布原料。 使用碱性或酸性凝固和再生浴以及任选的洗涤浴将海绵布中的成孔剂溶解并从纤维素黄原酸中再生纤维素。 海绵布是抗弯曲的,在干燥状态下不会破裂。 海绵布被设想用于工业和家庭的清洁和去污。
