Abstract
Fibras celulosicas modificadas que tienen un índice traccional con extension cero en seco, que es considerablemente menor que el índicetraccional con extension cero en seco de las correspondientes fibras celulosicas no modificadas. Las fibras que tienen traccional con extension ceroen seco pueden proporcionar estructuras fibrosas que tengan mejor sensacion en la mano, en comparacion con las fibras preparadas a partir de fibras nomodificadas. En particular, tales fibras modificadas proporcionan estructuras fibrosas con mayor flexibilidad, lo que se percibe como una mayor suavidad.La traccional con extension cero en seco reducida se alcanza, de preferencia, haciendo reaccionar las fibras con una enzima celulasa, ocon más de una, ycon un desligante, o con más de uno. El presente invento también se relaciona con una estructura fibrosa que tiene una densidad de no más que alrededorde 0,4 g/cm3, donde la estructura fibrosa comprende fibras celulosicasmodificadas que tienen un índice traccional con extension cero en seco que es,como mínimo, alrededor de 15% menor que el índice traccional con extension cero en seco de las correspondientes fibras celulosicas no modificadas; y dondela estructurafibrosa tiene un modulo de flexion por unidad tensional en seco que es, como mínimo, alrededor de 30% menor que el modulo de flexion porunidad traccional en seco de una estructura fibrosa preparada a partir de las correspondientes fibras no modificadas.Modified cellulosic fibers having a dry zero extension tractional index, which is considerably less than the dry zero extension tractional index of the corresponding unmodified cellulosic fibers. Fibers that have tractional with dry zero extension can provide fibrous structures that have a better feeling in the hand, compared to fibers prepared from nomodified fibers. In particular, such modified fibers provide fibrous structures with greater flexibility, which is perceived as greater softness. Traction with reduced dry zero extension is preferably achieved by reacting the fibers with a cellulase enzyme, or with more than one, and with a detachment, or with more than one. The present invention also relates to a fibrous structure having a density of not more than about 0.4 g / cm3, where the fibrous structure comprises modified cellulosic fibers having a dry zero extension tensile index which is at least about 15% less than the traction index with dry zero extension of the corresponding unmodified cellulosic fibers; and where the fiber structure has a flexural modulus per dry stress unit that is at least about 30% less than the flexural modulus per dry traction unit of a fibrous structure prepared from the corresponding unmodified fibers.
