Abstract
Characterization of thermal properties of different ages highland bamboo
fiber attributes extracted chemically and mechanically is the focus of
this work. The sample ware subjected to different analyses for each
corresponding age (1year, 2years, and 3 years) and NaOH Concentration
(untreated, 1%, 2%, and 3%) levels using thermogravimetric analysis
(TGA), differential scanning calorimetric (DSC), differential
thermogravimetric analysis (DTG), and differential thermal analysis
(DTA) for thermal properties characterization. Scanning electron
microscopy (SEM) for morphological studies and Fourier transform
infrared spectroscopy (FTIR) for the identification of functional groups
of the fibers. The surface appearance of the cell wall and microfibril
aggregates were changed by alkali treatment. From the SEM results, 3%
NaOH treated fiber resulted in more wrinkles on the surface of bamboo
fibers when compared with the 1% and 2%NaOH Bamboo fiber. Using
thermal analyse measurments, the study investigated weight loss
increased as alkali concentration increased but the scenario functioned
for proper concentration. The first Degradation stage is responsible for
the biggest weight loss since it includes the disintegration of all of
the fiber’s primary components (cellulose, hemicellulose, and lignin).
