Abstract
It has now been discovered that the sheet bulk of a tissue web may be increased, with little or no degradation in tensile strength, by forming the web with at least a portion of cellulosic fiber that has been reacted with a water soluble cellulose reactive agent such as a cyanuric halide or a vinyl sulfone and then reacting the fiber with monochloroacetic acid, or salts thereof, in the presence of a caustic.
