The present invention provides a durable tissue product produced from a tissue web that has been manufactured by applying a binder, such as by printing, to one side of the web and then contacting the binder applied side to a rotating dryer and creping the web therefrom. The side of the web opposite of the binder applied side is generally not treated with a binder, or the like, and is not subjected to creping. Further, the opposite side is generally formed from a layer of short, low coarseness cellulosic fibers, such as hardwood kraft fibers, and may be substantially free from long cellulosic fibers, such as softwood fibers. Despite forming the untreated surface from short fibers, the tissue product has good durability, such as a slough from about 6.0 to about 9.0 mg.

An absorbent material, such as a non-woven web or a tissue paper, includes continuous filaments and short fibers, the short fibers including natural and/or synthetic fibers or staple fibers. The absorbent material exhibits an absorbency speed of equal to or less than 2 s and a weight loss when washed of equal to or less than 5%. The absorbent material can be incorporated into a wipe.

A method of making paper is described. The method includes providing a calcium bicarbonate solution an providing a cellulosic fibrous material, the cellulosic fibrous material comprising a plurality of elongated fibers having a fiber wall surrounding a hollow interior, the fibrous material having a moisture content. The method also includes adding the calcium bicarbonate solution to the cellulosic fibrous material to form a pulp mixture, the calcium bicarbonate solution containing from 0.5% to about 16% solids of calcium bicarbonate by weight. Further, the method includes dewatering the pulp slurry using a wet press device such that the solids of the calcium bicarbonate by weight is pulsed above and below 16% solids by weight, finally ending above 16% calcium bicarbonate by weight and refining the pulp mixture such that at least some of the calcium ions become associated with the reactive sites in the fiber walls. Further still, the method includes forming a web from the pulp mixture and wet pressing the web.
