VARIATIONS IN STRENGTH AND BONDING PROPERTIES OF FINES FROM FILLER, FIBER, AND THEIR AGGREGATES

Fines from bamboo-hardwood pulp, talc, and aggregates from mill white water solids were blended in 36 different compositions. General proper ties of the sheets made from each composition, such as bulk, burst fac tor, breaking length, tear factor, and double fold, are reported Fiber strength (FS) and bond factor (BF) were measured using a Pulmac troub le shooter Variations in strength and bonding properties of the four d ifferent fines studies are discussed. In order to explain the filling and bonding mechanisms of the fines, schema were drawn based on optica l microscopy and SEM studies.
