    • A saturated hydroentangled fibrous web which includes a fibrous web having a plurality of entanglement loci as a consequence of subjecting the fibrous web to high pressure liquid jets and a saturant which is present in the hydroentangled fibrous web at a level of from about 10 to about 100 percent, based on the dry weight of the fibers. The saturant is adapted to render the saturated paper durable and ink jet printable. The fibrous web is composed of fibers, in which from about 20 to 100 percent by weight, based on the total weight of the fibers, are cellulosic fibers; from 0 to about 70 percent by weight, based on the total weight of the fibers, are mercerized cellulosic fibers; and from about 80 to 0 percent by weight of the fibers, based on the total weight of the fibers, are synthetic polymer fibers. The saturant includes from about 98 to about 70 percent, on a dry weight basis, of a latex reinforcing polymer having a glass transition temperature of from about -40.degree. C. to about 25.degree. C.; and from about 5 to about 70 percent, on a dry weight basis, of a cationic polymer. Either or both of the latex reinforcing polymer and the cationic polymer have crosslinkable functional groups. In addition to the fibrous web, a bonded nonwoven may be present.
    • 饱和水刺纤维网,其包括具有多个缠结位点的纤维网,其结果是将纤维网经受高压液体射流和在水力缠结纤维网中以约10至约100的水平存在的饱和物 基于纤维的干重。 饱和度适于使饱和纸耐用和喷墨打印。 纤维网由纤维组成,其中基于纤维总重量的约20至100重量%是纤维素纤维; 0至约70重量%,基于纤维的总重量,是丝光纤维素纤维; 和约80至0重量%的纤维,基于纤维的总重量,为合成聚合物纤维。 饱和剂包括基于干重约98%至约70%的玻璃化转变温度为约-40℃至约25℃的胶乳增强聚合物; 和约5-约70重量%的阳离子聚合物。 胶乳增强聚合物和阳离子聚合物中的任一种或两者具有可交联官能团。 除了纤维网之外,可以存在粘合的非织造布。
