Factors Affecting Kraft Pulp Yield

open access: yes, 2012
Kraft method, as a chemical pulping method, is commonly used in the worldwide. Pulps producing by using this method have a lower pulp yield compared to semi-chemical and mechanical pulping methods. However, strength properties of kraft pulp are higher than those of pulps producing from other pulping methods.

DEVELOPING NANOCELLULOSE-BASED BIOFILMS FROM KRAFT AND NaBH4 - MODIFIED KRAFT PULP

open access: yes, 2018
In this study, both kraft pulp and NaBH4-modified kraft pulp produced from the red gum tree (Eucalyptus camaldulensis) were used to generate nanofibrillated cellulose (CNF) and microfibrillated cellulose (CMF). These were then characterized by HPLC, FTIR, DSC and C-13-NMR.

Policy vs. Consumer Pressure: Innovation and Diffusion of Alternative Bleaching Technologies in the Pulp Industry [PDF]

open access: yes
In the late 1980s and early 1990s, concern over dioxin in both paper products and wastewater led to the development of techniques that reduced the use of chlorine in the pulp industry. Both regulatory and consumer pressure motivated this change.

Delignification, Yield, Defibreability, and Brightness of Pine Wood (Pinus sylvestris) Pulped Using the Alkaline Sulphite Method with the Addition of DDA and Ethylene Glycol

open access: yesBioResources
Sodium sulfite (Na2SO3) is known as a selective chemical agent for wood delignification. In this work, Scots pine (Pinus sylvestris) wood was pulped using alkaline sulfite (AS) with the addition of 1,4-dihydro-9,10-dihydroxy anthracene (DDA) [called also
