    摘要: A paper product and a method of making a paper product with a glabrous surface and adapted for use either dry or for use in a manually pre-moistened condition. The paper product having temporary wet strength exhibiting an initial normalized CD wet tensile strength of at least about 75 g/3 inch strip, preferably 105 g/3 inch strip as measured by the Finch Cup Test 5 seconds after immersion and a subsequent CD wet strength of less than 1/2 as measured 10 minutes after immersion. A temporary wet strength agent comprising uncharged chemical moieties such as aldehydes, and aldehydes containing polymers, polyols and cyclic ureas or mixtures thereof in the range of from about 2 pounds per ton to about 30 pounds per ton is added to the web. Optionally starch and a cationic nitrogenous softener/debonder is added. The starch and softener/debonder are added to assist in tailor making the desired paper product having temporary wet strength. The dry CD tensile strength of the paper product is from at least about 399 g/3 inches up to about 801 g/3 inches, and the tensile modulus is from about 10 to about 32 g/% strain while the GM MMD friction is from about 0.26 to about 0.10. When rubbed against a skin-like surface in a moistened condition, the paper product remains substantially free of pilling.
