    • A method of making an electrochemical cell electrode substrate includes creating an aqueous or dry mixture of chopped carbon fibers, chopped cross-linkable resin fibers that are still fuseable after being formed into a felt, such as novolac, a temporary binder, such as polyvinyl alcohol fiber or powder, forming a non-woven felt from either an aqueous suspension of the aqueous mixture or an air suspension of the dry mixture, by a non-woven, wet-lay or dry-lay, respectively, felt forming process, a resin cupng agent, such as hexamethylene tetramine may be included in the mixture, or it may be coated onto the formed felt, pressing one or more layers of the formed felt for 1-5 minutes to a controlled thickness and a controlled porosity at a temperature at which the resin melts, cross- links and then cures, such as 150°C - 200°C, and heat treating the pressed felt in a substantially inert atmosphere.

    • The invention relates to security paper and in particular to a method for the manufacture of security paper which is provided with high-quality watermarks. In particular such a method comprises forming a papermaking suspension comprising cellulosic fibres and polyvinyl alcohol fibres, which polyvinyl alcohol fibres are soluble in water at temperatures of from 95 DEG to 100 DEG C, dewatering the papermaking suspension through an embossed wire mesh or other embossed means, wherein the embossing creates a profile of peaks and troughs corresponding to the light and dark areas of the watermark, and the formed paper after dewatering with the watermark feature is thereafter dried to provide the resulting security paper.
    • 本发明涉及安全纸,特别涉及一种制造提供高品质水印的安全纸的方法。 特别地,这种方法包括形成包含纤维素纤维和聚乙烯醇纤维的造纸悬浮液,该聚乙烯醇纤维在95℃至100℃的温度下可溶于水,通过压纹丝网或其它压花装置将造纸悬浮液脱水 其中,压花产生对应于水印的明暗区域的峰和谷的轮廓,然后干燥具有水印特征的脱水后的成形纸,以提供所得的安全纸。
