    摘要： The present invention is directed to a fibrous substrate made of chemically bonded fibers, where the fibers are bound with a polymeric binder in an amount which is sufficient to bind the fibers together to form a self-sustaining web, and where the binder is characterized as having a wet tensile strength of greater than 4500 grams per inch (g/in) when measured at a 20 percent add-on on Whatman #4 CHR chromatography paper which is drum dried for 90 seconds at 210 to 215° F. and cured for 2 minutes at 300 to 325° F. Preferably the level of free formaldehyde in the fibrous substrate is less than 15 ppm. The emulsion binders of the invention may be used to bind fibers together in a substrate; may be used to bind pigment, colors or other substances to a substrate; may be used as a backing material; or may be used to finish or surface-treat a substrate. Because of the high level of crosslinking, substrates bound, or treated with the emulsion polymer have excellent wet strength and good durability/weatherability and water/solvent resistance.

    摘要翻译： 本发明涉及一种由化学键合的纤维制成的纤维基材，其中纤维与聚合物粘合剂结合，其量足以将纤维粘合在一起以形成自持式纤维网，并且其中粘合剂的特征在于 当在Whatman＃4 CHR色谱纸上的20％附加物上测量时，其湿拉伸强度大于4500克/英寸（g / in），其在210-215°F下滚筒干燥90秒并固化 在300至325°F下2分钟。优选纤维底物中游离甲醛的含量低于15ppm。 本发明的乳液粘合剂可用于将纤维在基材中结合在一起; 可以将颜料，颜色或其他物质结合到基材上; 可用作背衬材料; 或可用于完成或表面处理底物。 由于交联程度高，所以与乳液聚合物结合或处理的基材具有优异的湿强度和良好的耐久性/耐候性和耐水/耐溶剂性。
