Fluff pulp (also called communication pulp or fluffy pulp) is a type of chemical pulpmade from long fiber softwoods. Important parameters for fluff pulp are bulk and water absorbency.
More than 90% of the fluff pulps are fully bleached chemical softwood pulps, ofwhich more than 90% are pulps.
The most common raw material source for fluff pulps are southern bleached softwood Kraft(SBSK) from slash pine. SBSK from other species and NBSK are also used to make fluff pulp..
Thicker fibers are preferred to improve the bulk. The pulp may be impregnated with debonders before drying to ease defiration. Fluff pulp is normally made rolls(reels) on a drying machine (a simplified four drinier machine). The world wide production of fluff pulps amounts to about 3.5 million tons.

Fluff pulp for air-laid. products are defibrized in a hammer mill.defibration is the process of freeing the fibers from each other before entering the paper machine. Important parameters for dry defibration are shredding energy and knot content.
