Abstract
Bir geri kazanılan lifli besleme stoğundan çözünen kâğıt hamurunun üretilmesine yönelik bir yöntem. Selüloz, lignin ve hemiselüloz içeren bir lifli malzemenin sağlanması, söz konusu lif kaynağı ayrıca %0.1 ila 7 oranında lignin ve en fazla %3 oranında kül içeriğine sahiptir; bir azalmış içeriğe sahip liflerin üretilmesi için yaklaşık 0 ila 25°C sıcaklığında lifli malzemenin bir alkali ekstraksiyonuna maruz bırakılması, liflerin lignin içeriğinin azaltılması için oksidatif kimyasal reaktifler ile yürütülen bir ağartma işlemine böylelikle elde edilen liflerin maruz bırakılması; ve böylelikle elde edilen liflerin geri alınması. Yöntem aracılığıyla, çözünen kâğıt hamuru, geri kazanılan kâğıt ve karton ürünlerden üretilebilmektedir.
