ALTERNATIVE PULPING PROCESS FOR PRODUCING DISSOLVING PULP FROM JUTE

open access: yesBioResources, 2008
Dissolving pulps are the raw materials of cellulose derivatives and of many other cellulosic products. Jute is a very good source of cellulose and worthy of consideration for the production of dissolving pulp.

Tcf Bleaching Of Eucalyptus Kraft Pulp: The Selection Of The Sequence And The Best Conditions

open access: yes, 2015
Bleaching was conducted with conventionally oxygen-delignified pulp. The residual lignin was lowered either with an OAqZO or an OAqPeracidO treatment. Kappa numbers between 3 and 5 were achieved without any viscosity penalty. The bleachability was better

DESORPTION OF METAL IONS FROM KRAFT PULPS. PART 1. CHELATION OF HARDWOOD AND SOFTWOOD KRAFT PULP WITH EDTA

open access: yesBioResources, 2010
Chelation of unbleached and oxygen bleached hardwood and softwood kraft pulps with EDTA was studied. The main focus was on the desorption of magnesium, manganese, and iron due to their impact in TCF-bleaching.

TCF Short-Sequence Bleaching of Pinus Kesiya Pulp Made by Low-Temperature Kraft Pulping

open access: yes, 2011
In this paper, the TCF short-sequence bleaching (OQPaP) of pinus kesiya pulp from low-temperature kraft pulping with kappa number of 21.32 and viscosity of 1194mL•g-1 (the maximum pulping temperature was only 150°C) was optimized.
