The brown pulp was subjected to a bleaching process using an elemental chlorine-free (ECF) sequence. The results showed that prolonged impregnation provided greater delignification and lower reagent consumption than conventional impregnation. The pulp produced from prolonged impregnation with 14% effective alkali (EA) presented the best properties for dissolution, with intrinsic viscosity of 437 dm3\/kg, brightness of 88% ISO, xylan content of 3.48% and glycan content of 94.5%. TAC consumption was low for both impregnations. The study concluded that Bambusa vulgaris can be used in the production of dissolving pulp, mainly for viscose grade<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5084],"tags":[5093,5091,5092,5090],"release_year":[],"ppma_author":[4574,5085,5086,5087,5088,5089,4571],"class_list":["post-5269","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-70-number-1-2025","tag-bambusa-vulgaris","tag-ecf","tag-production-costs","tag-prolonged-impregnation"],"featured_image_src":null,"author_info":{"display_name":"Maro\u0161 Kov\u00e1\u010d","author_link":"https:\/\/www.woodresearch.sk\/cms\/author\/kovacvupc-sk\/"},"authors":[{"term_id":4574,"user_id":0,"is_guest":1,"slug":"ricardo-de-carvalho-bittencourt","display_name":"RICARDO DE CARVALHO BITTENCOURT","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5085,"user_id":0,"is_guest":1,"slug":"mathias-teixeira-marcal","display_name":"MATHIAS TEIXEIRA MAR\u00c7AL","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5086,"user_id":0,"is_guest":1,"slug":"stephani-caroline-de-lana-aredes","display_name":"ST\u00c9PHANI CAROLINE DE LANA AR\u00caDES","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5087,"user_id":0,"is_guest":1,"slug":"gabriel-martins-david","display_name":"GABRIEL MARTINS DAVID","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5088,"user_id":0,"is_guest":1,"slug":"tiago-guimaraes","display_name":"TIAGO GUIMAR\u00c3ES","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5089,"user_id":0,"is_guest":1,"slug":"gabriel-de-castro-baiao-brumano","display_name":"GABRIEL DE CASTRO BAIAO BRUMANO","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":4571,"user_id":0,"is_guest":1,"slug":"marcelo-moreira-da-costa","display_name":"MARCELO MOREIRA DA COSTA","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""}],"_links":{"self":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5269","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/comments?post=5269"}],"version-history":[{"count":4,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5269\/revisions"}],"predecessor-version":[{"id":5587,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5269\/revisions\/5587"}],"wp:attachment":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/media?parent=5269"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/categories?post=5269"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/tags?post=5269"},{"taxonomy":"release_year","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/release_year?post=5269"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/ppma_author?post=5269"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
