Abstract
A tissue product having superior properties of softness, handfeel, and strength is disclosed. The product may show a reduced degree of sloughing, that is, a reduction in the amount of paper particles or flakes that are generated from the product upon the abrasion of the tissue product. In one embodiment, a two furnish process is employed. In some applications, both hardwood fibers and softwood fiber sources may be employed. At least one fiber furnish is fractionated or separated into short and long fiber fractions. The resulting product exhibits reasonably good strength and softness, with reduced sloughing.
