Pulp that has been specially refined chemically. Pulp refined using the sulfite process is called dissolved sulfite pulp, and that refined using the kraft process is called dissolved kraft pulp. It is mainly used by dissolving it in chemicals, and is an important raw material for chemical products such as chemical fibers, cellophane, and CMC. It was formerly called rayon pulp because its main use was viscose rayon (→ viscose fiber).

化学的に特別に精製されたパルプ。亜硫酸法によりパルプを精製したものを溶解サルファイトパルプと呼び,クラフト法によるものを溶解クラフトパルプと呼ぶ。おもに薬品に溶解して使用され,化学繊維,セロファン,CMCなどの化学製品の重要な原料である。その用途がビスコースレーヨン (→ビスコース繊維 ) を主体としたため,以前はレーヨンパルプと呼ばれた。
