Effect of sonication treatment on fibrilating snake fruit (Sallaca) frond fiber

Abstract

Abstract. Aim of this research is to investigate influence of chemical and sonication treatment on fibrillating and mechanical properties of snake fruit frond fiber. The presence of surface impurities and the large amount of hydroxyl groups in natural fibers make less attractive for polymeric materials reinforcement. Effort to remove the impurities can be done by few treatments that consist of physical, chemical and mechanical treatment. Snake fruit frond bundle fiber were firstly subjected to chemical treatments with alkali solution, steaming at 2 bar and steam explosion at 6 bar by 40 times releasing of steam. Advanced treatment is done by flowing ultrasonic wave at 20 kHz by 90 -210 watt. The output of fibrillation can reach fiber in range 10 -25 nm compared with 10.72 µm in diameter for sonication and 6 bar in pressure of steam with 40x of rapidly steam release respectively.

Performance of Citric Acid-Bonded Oriented Board from Modified Fibrovascular Bundle of Salacca (Salacca zalacca (Gaertn.) Voss) Frond

“…This pattern of decline is relatively the same as that in previous studies using modified alkali [ 24 , 25 , 26 , 29 , 30 ]. Furthermore, the NaOH + Na 2 SO 3 treatment was more effective in maintaining α-cellulose, hemicellulose, and lignin content compared to previous studies by Darmanto et al [ 31 ] using S. zalacca as raw material with higher concentration and high-energy steam.…”
