Estimating the term…
The present invention relates to tissue products comprising high yield hesperaloe fiber having improved wet performance, such as improved absorbency, CD Wet/Dry Ratio and CD Wet Durability. The addition of high yield hesperaloe pulp 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.
A tissue product comprising wood pulp fibers and from about 5 to about 50 weight percent high yield hesperaloe pulp fibers, the tissue product having a CD Wet/Dry ratio greater than about 0.30 and a Wet CD Durability greater than about 1.75.
A single-ply through-air dried tissue product comprising wood pulp fibers and from about 5 to about 50 weight percent high yield hesperaloe pulp fibers, the tissue product having a basis weight from about 30 to about 60 gsm, a GMT greater than about 1,200 g/3″, a CD Wet/Dry ratio greater than about 0.30 and a Wet CD Durability greater than about 1.75.
