Abstract
La presente invención proporciona una fibra celulósica modificada que tiene capacidades reducidas de enlace de hidrógeno. La fibra modificada formada de acuerdo con la presente invención puede ser útil en la producción de productos de papel tisú que tienen volumen y suavidad mejorados. De forma más importante, la fibra modificada es adaptable para los procesos actuales de elaboración de papel tisú y puede incorporarse dentro de un producto de papel tisú para mejorar el volumen y la suavidad sin una reducción no satisfactoria en la tracción.
