    • A nonwoven fabric, particularly composed by long-stock synthetic resin yarns such as polyethylene and polypropylene is provided at one or both surfaces thereof with an ink-setting layer formed by coating, drying and curing a resin composition containing some of acrylic resins, synthetic rubbers and polyester resins. The ink-setting layer is excellent in the transfer property and fixing ability to an oil ink which is ordinarily used for offset printing, and prevents the nonwoven fabric from being swelled or transformed by a petroleum high-boiling-point solvent contained in the oil ink. Preferably, a low-temperature cross-linking agent is incorporated with the resin composition of the ink-setting layer so as to complete cross-linking of the resin composition at a low temperature at which heat shrinkage or heat damage of the nonwoven fabric will not be caused, in a shortened period of time. Moreover, when 10 to 40% by weight of non-calcined clay, 1 to 15% by weight of titanium dioxide and 1 to 10% by weight of calcium carbonate or calcined clay are incorporated as fillers in the resin composition of the ink-setting layer, the ink-setting layer has improved absorbability, drying ability and fixing ability to a printing ink. A preferable construction of the nonwoven fabric has a first layer containing the low-temperature cross-linking agent and a second layer containing the specific filler ingredients.
    • 在其一个或两个表面上,通过涂布,干燥和固化含有一些丙烯酸树脂,合成橡胶的树脂组合物形成的油墨凝固层,提供特别是由长股合成树脂丝如聚乙烯和聚丙烯构成的无纺布 和聚酯树脂。 油墨设置层通常用于胶版印刷的油墨的转印性能和定影能力优异,并且防止非织造织物被包含在油墨中的石油高沸点溶剂膨胀或转化 。 优选地,将低温交联剂与油墨凝固层的树脂组合物结合,以在无纺织物的热收缩或热损伤不会在低温下完成树脂组合物的交联 在缩短的时间内被引起。 此外,当将10至40重量%的未煅烧粘土,1至15重量%的二氧化钛和1至10重量%的碳酸钙或煅烧的粘土作为填料加入到油墨固化树脂组合物中 油墨凝固层对印刷油墨具有改进的吸收性,干燥能力和定影能力。 非织造布的优选结构具有包含低温交联剂的第一层和含有特定填料成分的第二层。

    • A sheet-shaped heat-generating body comprising a sheet-­shaped substrate comprising irregularly arranged fibers and having a multiplicity of gaps among the fibers, an oxidizable metal powder dispersed in and supported by the substrate, and an inorganic electrolyte solution containing activated carbon mixed and suspended therein with which the substrate supporting the oxidizable metal powder dispersed therein is impregnated. Since the entire structure of the sheet-shaped heat-generating body is integrated, with the fibrous and porous sheet-shaped substrate assuring uniform distribution and firm support of the oxidizable metal powder or the heat-generating substance, the body is flexible, is free from one-sided distribution of the heat-generating substance, and has excellent heat generating capability.
