Abstract
The present invention provides a modified cellulosic fiber having reduced hydrogen bonding capabilities. The modified fiber formed in accordance with the present invention may be useful in the production of tissue products having improved bulk and softness. More importantly, the modified fiber is adaptable to current tissue making processes and may be incorporated into a tissue product to improve bulk and softness without an unsatisfactory reduction in tensile.
Claims6
A tissue web comprising unmodified and modified wood pulp fibers, the modified wood pulp fibers consisting of wood pulp fibers reacted only with a reagent consisting essentially of a water soluble cyanuric halide having the general Formula (I):
- where R1 equals F, Cl, Br, or I and R2 equals (CH2)n—OH (n=1-3), (CH2)n—COOH (n=1-3), C6H5—COOH, or HSO3X where X equals (CH2)n (n=1-3) or C6H4, the modified wood pulp fibers having a nitrogen content greater than about 0.2 weight percent, the tissue web having a basis weight from about 10 to about 60 gsm and a sheet bulk greater than about 10 cc/g.
