资源简介：
The invention relates to fibrous structures having desirable physical properties， such as good tensile strength， low stiffness and high bulk， manufactured using a fiber furnish comprising cellulosic fibers having a pH of 5.0 or less and at least one strength resin. Not only do structures prepared with acidic fibers have desirable physical properties， they may also be manufactured in an energy efficient manner. To achieve the greatest energy savings it is generally desirable that acidic fibers not be subjected to mechanical treatment， such as by refining， prior to forming the fiber into a fibrous structure. Further， it may be desirable to subject the remainder of the fiber furnish to a minimal degree of mechanical treatment， such as by refining， so as to produce a furnish having a freeness greater than about 550 mL.
