Abstract
The present invention relates to tissue products comprising high yieldfiber having improved wet performance, such as improved absorbency, CD Wet/Dry Ratio and CD Wet Durability. The addition of high yieldpulp fibers surprisingly improves the CD Wet/Dry ratio without negatively affecting the absorbency of the tissue product. For example, tissue products of the present invention generally have an Absorbent Capacity greater than about 6.0 g/g, such as from about 6.0 to 8.0 g/g. As such the tissue products are durable when wet, but are still sufficiently absorbent. This balance of absorbency and wet strength is not found in the prior art without resorting to adding latex binders or the like to the tissue product.
