In this study, pulps from Bambusa vulgaris and Dendrocalamus asper were compared to industrially produced Eucalyptus spp. pulp in terms of morphology and mechanical properties. The pulping processes of Bambusa vulgaris and Dendrocalamus asper resulted in total yields of 71.3% and 77.0% respectively. Both bamboo species had higher mechanical properties compared to Eucalyptus spp. pulp. Bambusa vulgaris pulp showed superior mechanical properties and required less energy for refining, making it suitable for applications requiring high tensile strength. Dendrocalamus asper pulp demonstrated higher bulk and liquid absorption capacity, making it more suitable for certain applications.
In this study, pulps of the species Bambusa vulgaris and Dendrocalamus asper were produced through the chemi-thermo mechanical pulping process, which had their morphological and mechanical properties compared with industrially produced Eucalyptus spp. pulp. The total yields of the pulping processes were 71.3 and 77.0% for the species Bambusa vulgaris and Dendrocalamus asper, respectively. The higher basic density presented by the biomass of the Dendrocalamus asper species can lead to a high productivity. Both bamboo species led to pulps with higher mechanical properties compared to industrial Eucalyptus spp. pulp. The pulp of Bambusa vulgaris stood out in terms of mechanical properties, reaching a higher level of mechanical properties with less energy spent on refining, being indicated for the production of papers for applications where high tensile index is required. Dendrocalamus asper pulp proved to be more suitable for applications, in which high liquid absorption capacity is required due to its high bulk.
