The effect of non-defiberized fiber aggregates (knots) on the former properties was evaluated. Processual variations in pulping and bleaching conditions revealed variability within 15% in the absorption capacity of fluff pulps and within 25% in the network strength of the air-laid formulations. These variations were attributed to changes in the chemical composition of BEKPs and fiber morphology. The importance of pulp bleaching sequence on the quality of BEKPs for fluff applications was highlighted. BEKPs, having a high residual xylan content with a greater amount of uronic\/hexenuronic moieties and coarser\/deformed fibers, revealed the best performance in fluff applications. The coarseness was considered a critical morphological parameter of the fibers, strongly affecting the porosity of air-laid formulations, which determined the absorption capacity and the network strength. The absorption capacity of fluffed BEKP was comparable of commercial bleached softwood kraft pulp (BSKP), although the latter showed almost triple the network strength of air-laid formulations produced with BEKP. BSKP proved to be much more vulnerable to dry defiberization conditions than BEKP and suffered a pronounced cut of fibers, producing larger amounts of fines (dust) and stronger undesirable peeling and straightening of fibers. BEKPs can be considered a promising raw material for fluff applications, whose basic properties can be adjusted according to the needs by varying conditions in the pulping and bleaching process steps. <\/jats:p>","DOI":"10.1177\/1558925020980146","type":"journal-article","created":{"date-parts":[[2020,12,17]],"date-time":"2020-12-17T19:41:46Z","timestamp":1608234106000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Potential of bleached eucalyptus kraft pulp for applications in nonwoven fibrous fabrics"],"prefix":"10.1177","volume":"15","author":[{"given":"Sofia M","family":"Rebola","sequence":"first","affiliation":[{"name":"CICECO, Chemistry Department, University of Aveiro, Aveiro, Portugal"}]},{"given":"Joana","family":"Ferreira","sequence":"additional","affiliation":[{"name":"CICECO, Chemistry Department, University of Aveiro, Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6304-5105","authenticated-orcid":false,"given":"Dmitry V","family":"Evtuguin","sequence":"additional","affiliation":[{"name":"CICECO, Chemistry Department, University of Aveiro, Aveiro, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2020,12,17]]},"reference":[{"key":"bibr1-1558925020980146","unstructured":"Printing and writing paper demand worldwide from 2018 to\u20092030,\u2009https:\/\/www.statista.com\/statistics\/1089445\/global-writing-and-printing-paper-demand\/ (accessed 20 July 2020)."},{"key":"bibr2-1558925020980146","first-page":"110","volume":"3","author":"Parham RA","year":"1980","journal-title":"Pulp Paper"},{"key":"bibr3-1558925020980146","first-page":"51","volume":"16","author":"Young D","year":"2007","journal-title":"Nonwovens World"},{"key":"bibr4-1558925020980146","unstructured":"Strandberg A, Hogman S, Tufvesson G.
