Enhancing Antimicrobial Activity in Unbleached Kraft Pulp using Laccase and Phenolic Compounds
Unbleached kraft pulp fibers were reacted with laccase in the presence of different phenolic compounds (isoeugenol, butyl p-hydroxybenzoate, p-coumaric acid, and ferulic acid) in order to confer them with new properties. After the enzymatic stage, antimicrobial tests demonstrated that the handsheets formed from the laccase/phenolic-treated pulp showed ...

Merging materials processing tricks inspired by mussel and mistletoe fiber fabrication, solutions of cationic mussel byssus proteins were mixed with modified anionic nanocrystalline cellulose, producing distinctive core‐shell condensates. Simple processing of condensate suspensions using freeze‐drying produced hierarchically structured porous protein ...

The impact of nanotechnology on textile coloration—A mini‐review
Abstract Coloration is a key feature in the textile industry that adds value to the final apparels. This coloration of textile products is done by conventional methods which involve huge amounts of water pollution and wastages of textile colourants. Several approaches have been taken to eliminate these issues by advanced dyeing methods, however, due to

Filament spinning of unbleached birch kraft pulps: Effect of pulping intensity on the processability and the fiber properties [PDF]
Man-made lignocellulosic fibres were successfully prepared from unbleached birch kraft pulps by using the Ioncell-F technology. Pulps with different lignin content were produced by tailored kraft pulping with varying intensity. The degree of polymerization of the pulps was adjusted by acid-catalyzed hydrolysis and electron beam treatment.

HEXENURONIC ACID REMOVAL FROM UNBLEACHED KRAFT EUCALYPTUS PULP BY PEROXYMONOSULFURIC ACID
The use of peroxymonosulphuric (Ps) acid to remove hexenuronic acid (HexA) present in unbleached eucalyptus kraft pulps was evaluated here. HexA is formed during pulping and is held responsible for reagent consumption during bleaching. Laboratory experiments, using oxygen predelignified eucalyptus kraft pulps (kappa number around 9), treated at 20-110C
