Extraction and processing of Indian Okra fibre for Industrial bio-packaging

Abstract

An effortless fibre extraction process (7 days water retting with urea) and industrial usage of the crop has been explored. The characterization study carried out on okra fibres confirms them as potent as higher grade jute on account of their similar composition, morphology and properties, which makes them one of the best fibres for heavy duty bio-packaging and industrial textile uses. Spinning trial proves its fitness for bulk processing in commercial scale machines of jute, both in elementarily (pure) and blends. Commercial scale trial of okra:jute blend (25:75) spun threads shows its good spinning performance and endurance (strain 2.9%; tenacity 12.4 cN/tex; modulus 592.3 cN/tex). The strength of the jute: okra cloth and the seam strength are found well within the standard specifications for manufacturing standard bio-packing of 50 kg for food grains. Thus, the use of okra agro residues not only results in cleaner post-harvest practices, but also adds to sustainability of the modern technologies and progressive farmers.
