Title:
CELLULOSE-BASE FIBROUS MATERIAL
Document Type and Number:
WIPO Patent Application WO/2007/123229
Kind Code:
A1
Abstract:
The invention provides a cellulose-base fibrous material for the production
of high-opacity paper and sheeting which have low density and excellent surface
characteristics and exhibit excellent dimensional stability in spite of their
having high strength. A fibrous material made mainly of a cellulose having a scaly
outer fibril made of a microfibril aggregate exhibits a higher fiber stiffness
than that of a fibrous material having a yarn-type outer fibril at the same freeness
level and has a lower water retention and a larger specific surface area than those
of the latter material. Use of the fibrous material of the invention brings about
paper and sheeting which have low density, excellent surface characteristics,
excellent dimensional stability, and high opacity.
