Bleached kraft pulp production from Pinus tecunumanii (Eguiluz e Perry) Produção de polpa kraft branqueada de Pinus tecunumanii (Eguiluz e Perry)

open access: yesRevista Árvore, 2005
The use of 12-year-old Pinus tecunumanii (Eguiluz e Perry) grown in Colombia was evaluated for bleached kraft pulp production. Kraft pulps of kappa number 30 ± 1 were produced, and oxygen delignified and bleached to 90% ISO with ECF processes.

Successive twin-wire roll forming of two-ply paper with softwood kraft pulp and recycled pulp û€“ effect of kraft-ply formation on Z-strength - OPEN ACCESS

open access: yes, 2017
Kraftliner and kraft-top liner typically consists of two or more plies that are formed separately and combined by couching. The Z-strength tends to be limited by the ply adhesion, and the softwood kraft pulp used is commonly refined beyond the optimum ...

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

The impact of nanotechnology on textile coloration—A mini‐review

open access: yesColoration Technology, Volume 142, Issue 1, Page 26-51, February 2026.
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
