摘要：
A process for preparing a sheet with improved stiffness by mixing a fiber, a latex having minimum film-forming conditions greater than the conditions the sheet reaches during drying and a fugitive coalescing agent. The mixture is collected and dried under conditions less than the minimum film-forming conditions of the latex. The process enables hard latexes to be employed which do not form films under the drying conditions of the sheet whereby the hard latexes can contribute to the stiffness of the final sheet. A sheet prepared by the process is also provided.
摘要（中）：
通过混合纤维，具有大于干燥期间片材达到的条件的成膜条件的胶乳和短暂的聚结剂，制备具有改善刚度的片材的方法。 收集混合物并在小于胶乳的最低成膜条件的条件下干燥。 该方法使得能够在片材的干燥条件下不形成膜的硬胶乳，由此硬胶乳可以有助于最终片材的刚度。 还提供了通过该方法制备的片材。
