MULTILAYERED TISSUE HAVING REDUCED HYDROGEN BONDING

The disclosure provides a multilayered tissue web comprising treated cellulosic fibers selectively disposed in one or more layers, wherein the tissue layer comprising treated fibers is adjacent to a layer comprising untreated fiber and which is substantially free from untreated fiber. Generally the treated fibers have a rate of substitution of about 0.02 to 0.07. In this manner, the disclosure provides a multi-layered tissue web having treated fiber selectively incorporated therein, where the tissue web has basis weight greater than about 10 grams per square meter (gsm), such as from about 10 to about 50 gsm, a sheet bulk greater than about 8 cc/g, such as from about 8 to about 15 cc/g and Stiffness Index less than about 15, such as from about 8 to about 12. La descripción proporciona una trama de papel tisú de múltiples capas que comprende fibras celulósicas tratadas dispuestas selectivamente en una o más capas, en donde la capa de papel tisú que comprende las fibras tratadas es adyacente a una capa que comprende la fibra no tratada y la cual está sustancialmente libre de fibra no tratada. Generalmente, las fibras tratadas tienen una tasa de sustitución de aproximadamente 0.02 a 0.07. De esta manera, la descripción proporciona una trama de papel tisú de múltiples capas que tiene fibra tratada incorporada selectivamente en esta, donde la trama de papel tisú tiene un peso base mayor que aproximadamente 10 gramos por metro cuadrado (gsm), tal como de aproximadamente 10 a aproximadamente 50 gsm, un volumen de la lámina mayor que aproximadamente 8 cc/g, tal como de aproximadamente 8 a aproximadamente 15 cc/g y un índice de rigidez menor que aproximadamente15, tal como de aproximadamente 8 a aproximadamente 12.
