Title:
セルロース分散体
Document Type and Number:
Japanese Patent JP4255619
Kind Code:
B2
Abstract:
A cellulose dispersion which is a dispersion comprising a dispersing medium and a cellulose having a fraction of cellulose I type crystal component of not more than 0.1 and a fraction of cellulose II type crystal component of not more than 0.4 and in which the average particle diameter of the constitutive cellulose is not more than 5 mu m. A cellulose particulate and a cellulose composite particulate which have an average particle diameter of 0.2 to 20 mu m, a ratio of long diameter (L) to short diameter (D) observed through a scanning electron microscope (L/D) of not more than 1.2 and a coefficient of aggregation of 1.0 to 3.0. The present invention provides a cellulose dispersion which has an excellent effect such as dispersion stability or the like and is high in transparency. Moreover, it provides a cellulose particulate and a cellulose composite particulate which have such performances as no rough feel, excellent rolling properties, high dispersibility and the like.
