ABSTRACT

Extraction, treatment and characterization of pineapple leaves fibres was achieved. The study revealed that water retting is the best way to extract fibers as it is easily controlable which reduces the chance of reducing the strength of fibres. Also,it was observed that dried pineapple leaves fibres take longer time to ret compare to fresh leaves.The fibers were treated using NaOH for scouring while bleaching was carried out using H₂O₂. The treatment of fibers was conducted to get rid of fat, wax and other impurities as well as undesired colors bonded to fibers that could not be removed through water retting. The best scouring concentration of NaOH was found to be 1.25 % while the best bleaching concentration of H₂O₂ was found to be 10 %. More so, FTIR was carried out for both treated and untreated fibers and it was shown that wax, fat and other impurities can be removed by fibres’ scouring and bleaching. This was further confirmed by the use of Soxhlet to extract ethanol-benzene extract from both treated and untreated fibres, where untreated fibres showed a considerable weight loss while the treated fibers did not show any weight loss. Thereafter, mercerization was carried out and it was found out that the best mercerization concentration for pineapple leaves fibres is NaOH is 10%. Furthermore, the quantitative analysis of pineapple leaves fibers revealed that the fibers have, ethanol-benzene extractives of 2.6 %, pectin content of 1.53%, Lignin content of 12%, cellulose content of 79% and ash content of 2.15 %. The fibers showed a water, oil and vapor absorption of 82%,32 % and 29% respectively. Also, the thermal analysis showed that the degradation temperature is 400 ⁰C while the fibers started to display thermal instability at 350 ⁰C. Moreover, SEM and XRD analysis showed that the treatment of fibres participated in removal of wax and oil as well as other gummy materials, which also is in line with FTIR results obtained.
