ABSTRACT: High-moisture regains nature of cellulosic fibers considered one of the
critical drawbacks for jute-based applications. To minimize this by developing
better interfacial adhesion, a hydrophobic nonwoven wet-laid glass fiber sheet
used the woven jute fabric in this experiment. For this purpose, woven jute
fabric was categorized into untreated,
silane, alkali, and alkali-silane combined treatment then compounded with the
solution of polycaprolactone (PCL). Fabrication of composites performed the following sandwich method based on different hot-pressing time with temperature for detecting a
prominent fabrication parameter. Surface treated jute fibers characterized
using FTIR spectroscopy. Hence, the
mechanical and thermal properties of composites were investigated to
find the consequence of chemical treatments into woven jute fabric.
Alkali-silane combined chemical treatments resulting in improved 48.38% of
tensile strength over untreated optimized composites. Scanning electron
microscope (SEM) used for displaying interfacial adhesion between fiber and
polymer matrix. Besides, further investigation demonstrated due to the combined
chemical treatment of alkali-silane optimized composites significantly enhanced
the thermogravimetric (TGA) stability in contrast to other composites.
