“…Peracetic acid (PA) is a strong oxidizing agent with excellent bleaching properties suitable for the extraction of cellulose, as it has low environmental impact when compared to that of the chlorinated reagents employed in conventional processes used for cellulose extraction. PA decomposes during bleaching into nontoxic and antimicrobial decomposition products 23,26,27 …”

“…PA decomposes during bleaching into nontoxic and antimicrobial decomposition products. 23,26,27 Considering that the extraction of cellulose from OB with the employment of ultrasound or PA has not been reported in the literature, the objectives of this work were to extract cellulose from OB using a combination of ultrasound and PA treatment performed in a single-step procedurea less polluting process than the conventional processesand to characterize the obtained material according to its cellulose, hemicellulose and lignin contents, and its crystallinity, thermal stability and water sorption behavior.…”

BACKGROUND Brazil is responsible for 60% of the global production of orange juice, accounting for over three‐quarters of global orange juice exports, resulting in large quantities of orange bagasse (OB). This is an underutilized byproduct of the orange juice industry and corresponds to 50% of the fruit weight. The objectives of this study were to produce cellulose from OB using a combination of ultrasound and peracetic acid (PA) treatment, and to characterize the obtained materials according to their microstructure, crystallinity, thermal stability and water sorption behavior, and their cellulose, hemicellulose and lignin contents. RESULTS Ultrasound pretreatment alone was not effective in altering the composition of OB. Samples subjected to both ultrasound and PA presented higher cellulose contents and lower hemicellulose and lignin contents in comparison to their respective samples undergoing PA treatment alone. The sample subjected to ultrasound for 10 min at a 30% amplitude combined with PA treatment for 24 h (USPA.24) resulted in the highest crystallinity index (54%), with 81.49% cellulose, 0.88% hemicellulose and 2.68% lignin. The increase in cellulose content of samples also resulted in lower water‐holding capacity, solubility and water adsorption capacity of samples. CONCLUSION Ultrasonication associated with PA treatment can be considered a promising approach and effective protocol for the extraction of cellulose from lignocellulosic residues, and it has the advantages of simplicity and environmental friendliness when compared to conventional methods, reducing the toxicity and amount of the resulting effluents. © 2020 Society of Chemical Industry (SCI)

“…They are broadly implanted in thin-walled parenchymatous ground tissue made up of a fibrous sheath, vessels, fibers, phloem, and parenchymatous tissues, albeit Jute fiber is a multicellular fiber made up of many single fibers. The diameter of raw Jute fiber was around 61 µm) [17], whereas the fiber diameter for OPF was 11 -19.7 µm [18]. The maximum SAC for 100% of OPF content is unable to exceed 0.9, as can be observed in Figure 3.…”

Noise is defined as an unpleasant or loud sound, which may cause disturbance to others. It can damage an inner ear and even cause noise-induced hearing loss, threatening health and well-being. Researchers have successfully studied and invented many different types, shapes, and sizes of sound absorbers to absorb/control unwanted noises. A simple method used to control noise is by controlling the noise source using acoustic absorption panels, reducing noise along the transmission path, and protecting the noise at the receiving end before it reaches the receiver. Presently, the market or in most developed countries uses synthetic materials for buildings to absorb sound. The commonly used synthetic materials are glass or mineral fibers as they can be produced chemically in the factory very quickly. However, materials such as foam, rock wool, and glass wool made from minerals are recognized for their poisonous and polluting effects, which are harmful to human health and the environment. This paper reported the effect of substitution of Jute on the acoustic performance of Oil Palm Frond (OPF) natural fibers (150 kg/m3) with a thickness of 19 mm. Jute is suitable for insulating, antistatic, and low thermal conductivity. It also has a promising result of sound absorption coefficient (SAC) at lower frequency range (50 - 1000 Hz), and on the contrary for OPF, the SAC is only promising at higher frequency range (2000 Hz - 6400 Hz). Thus, it will be very remarkable to study these two blending fibers' acoustic performance. The findings show the substitution of Jute to broaden the frequency range of SAC above 0.8. For 20 % of jute substitution, SAC's frequency range above 0.8 is 1600 – 6400 Hz. Whereas for both 40 % and 60 % of jute substitution, the frequency range is marginally widened to 1400 – 6400 Hz. For 80 % of jute substitution, the frequency range of SAC above 0.8 has been increased to 1000 – 6400 Hz. An impressive result has been observed, where 100 % OPF unable to reach the SAC of 0.9 throughout the frequency range of 0 – 6400 Hz. Jute has proved its ability to improve its acoustic performance at a more comprehensive frequency range.

In this research, a new method was developed for extracting fibre directly from the ramie. High-speed water treatment was found to be beneficial for the removal of husks. The proposed fibre extraction process included retting, first high-speed water treatment, oxidative degumming and second high-speed water treatment. The retting time and hydrogen peroxide concentration suitable for the removal of husks were found to be 7 days and 8 g/L, respectively. There was very little residual husk in the extracted sample. Scanning electron microscopy showed that most of the gums were removed. The fineness and tenacity values of the ramie fibre that was extracted using the proposed method were close to the values of the ramie fibre extracted by using the traditional process. As compared with the traditional process, the chemical agent consumption, boil time and labour intensity of the new extraction method were less.
