Ethnobotany of natural fibres: bactris stosa (tucum) in a traditional rural community


This work aimed to study the characteristics of the fibres of the species Bactris setosa (‘tucum’) used by close-knit social groups, located in Sorocaba – Săo Paulo – Brazil, in basketmaking techniques, for possible applications in textile activity. Optical microscopy (NBR 13 538:1995) and Tensile Properties (ASTM D 3 822-2001) were used to assess properties such as the fibre structre, linear density, breaking force, elongation at break and breaking tenacity of each species. Bactris setosa showed a longitudinal view similar to that of sisal; an average linear density of 41.2 tex, a tenacity average of 11.96 cN/tex, closer to fiberglass, and an elongation ranging between 1.35 and 3.87%.It is important to clarify the delicacy and detail of the tests, and from this we highlight the importance of carrying out these studies, based on which science and technology must be linked with socio-environmental aspects.
