To investigate effect of sericite on pilot Fourdrinier paper making for loading, with respectively 15% additive sericite on talc, we made newprint with TMP, and then tested sericite on talc, we made newprint with TMP, and then tested sericite and talc abrasion, physical and strength properites of the paper. Consequently, as a loading materials, sericite had outstanding properties different from talc from the result of this paper; 1. Sericite was a good loading materials because the quantity of abrasion was small. 2. Sericite had a good physical properties of Foudrinier paper because brightness. ash content and water absorption were high. 3. Newsprint paper strengthes of additive talc were nigher than those of additive sericite.
