PET knitted fabric was melted and cooled by hot pressing at 250 °C to obtain a compacted sheet. Only white (WF_PET) used study the recycling process compression grinding powder then melt spinning different take-up speeds compared bottle grade (BO_PET). had good fiber formability better suited for of recycled (r-PET) fibers than grade. Thermal mechanical properties r-PET improved in terms crystallinity tensile strength with increasing speed (500 1500 m/min). Fading color changes from original...
Empty fruit bunch oil palm (EFBOP) fibres were surface modified by four different methods, propionylation, vinyltrimethoxy silanization, PPgMA dissolution modification, and blending, integrated into a polypropylene (PP) matrix.The designed biocomposites subjected to an absorption process at temperatures.Their water uptake behaviour was compared with the unmodified fibre biocomposites.An increased content temperature resulted in for all of biocomposites.The containing showed reduction uptake,...
An epoxidized natural rubber (ENR) blend with chlorhexidine gluconate (CHG) was prepared using a two-roll mill at 130 °C. CHG added concentrations of 0.2, 0.5, 1, 2, 5, and 10% (w/w) as an antimicrobial additive. The ENR showed the best tensile strength, elastic recovery, Shore A hardness. ENR/CHG exhibited smooth fracture surface. appearance new peak in Fourier transform infrared spectrum confirmed that amino groups reacted epoxy ENR. inhibition zone against Staphylococcus aureus. proposed...
This work was done to improve the interfacial adhesion and engineering performance of polyvinyl alcohol/polylactic acid laminate film by altering alcohol phase surface properties via incorporating microfibrillated cellulose modified propionylation. Incorporating into improved between layers during laminating process. Improved peel strength tensile confirmed that can produce better bonding polylactic mechanical interlocking cohesive forces at interface. Modified (3 wt%) increased 40%...
A novel poly (lactic acid) (PLA) composite with excellent mechanical properties, toughness, thermal stability, and water resistance was developed using a reactive melt-blending technique. PLA melt mixed epoxy resin (EPOXY) bamboo pulp (PULP) to improve its reaction properties. FTIR analysis confirmed the successful of PLA/EPOXY/PULP composites; groups EPOXY reacted -COOH -OH PULP. The PLA/EPOXY/PULP5 showed high tensile strength (67 MPa) toughness 762 folding cycles, whereas highest 77 MPa...
This research investigated and developed a laminate packaging film of poly(lactic acid) (PLA) poly(vinyl alcohol) (PVA) containing modified chitosan nanoparticles (MCSNPs) treated with 3-(trimethoxysilyl)propyl methacrylate silane (TMSPM) which functioned both as reinforcement an antimicrobial filler. Electron beam irradiation caused crosslink between the PVA MCSNP molecules via free radical carbonyl in group TMSPM-grafted hydroxyl alcohol). improved hydrophobicity. In addition, PVA-g-MCSNPs...
The decomposition behaviours of composites made poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and sisal were assessed in terms thermal stability kinetics, under inert oxidative conditions, by means multi-rate linear non-isothermal thermogravimetric experiments. A statistical design experiments was applied to study the influence addition (0–10–20–30%wt), presence coupling agent (Yes/No) conditions work (inert or oxidative). An improvement thermo-oxidative PHBV with observed for all...
Lignocellulosic biocomposite is a promising biodegradable materials, though improvement of the interfacial adhesion between cellulose fibre and polymer matrix still challenged. Therefore, this w ...
The aim of this work was to study the effect chemical surface modifications on empty fruit bunch oil palm fibre/polypropylene composite properties. By FTIR spectra, propionylated fibre and PPgMA-modified showed presence a carbonyl group esters while vinyltrimethoxysilane-treated peak silicate, confirming that were successful. PPgMAmodified PP at content 20% demonstrated highest modulus 0.71 GPa unmodified 0.56 GPa. DSC analysis, same 5% crystallinity 46% 44% respectively whereas lower 38%....
Polyester/cotton fabrics with different proportions of Tetron Cotton, TC (35% Cotton/65% PET), and Chief Value CVC (60% Cotton/40% were investigated by removing the cotton component under various phosphoric acidic conditions including use cellulase enzymes. The remaining polyethylene terephthalate (PET) was spun using melt spinning method. Only 85% H3PO4-Enz_TC could be into consistent filament fibers. effects Acid-Enz (obtained from a powder preparation H3PO4-Enz_TC) at weight amounts (1,...
Alkaline pretreated hemp fibers were modified by steam explosion and/or silanization before being compounded with polylactic acid (PLA). The fungal biodegradation of the PLA/hemp composite was investigated using Aspergillus niger TISTR 3153 in an aqueous medium for 28 days, following ISO 846: 1997 standard method. influence different physicochemical modifications on evaluated terms molecular weight, chemical structure, mechanical properties, thermal and hygroscopic properties. results showed...
