Biodegradable composites were fabricated using chemically treated woven jute fiber, a biodegradable polymer (biopol), and 2–4 wt. % montmorillonite K10 nanoclay by compression molding process. Physical, mechanical, and biodegradability properties of these composites were evaluated in this study. Morphology of modified surfaces of jute fabrics examined using scanning electron microscopy and Fourier transform infrared spectroscopy revealed improved surfaces for better adhesion with matrix. Nanoclay infused samples demonstrated lower moisture and water absorption compared with treated jute fiber biopol composites and untreated jute fiber biopol composites. The effect of moisture absorption on flexural properties and degradability on the dynamic mechanical properties was also studied. Flexural properties were found to degrade with moisture absorption, and the percentage reduction was lower in nanoclay infused samples compared with samples without nanoclay. Storage modulus decreased with biodegradation and rate of decrease was lower in nanoclay infused specimens.

Natural fibers are biodegradable, non toxic, recyclable, energy efficient and eco-friendly, which reduce the issue of waste disposal as seen in the case of synthetic fibers. Jute is the cheapest lignocellulosic long vegetable bast fiber and abundantly available in South Asia, especially in Bangladesh. It offers a number of benefits as reinforcement in synthetic polymers. In the present study, jute fiber was chemically treated in order to make it fire, rot and water retardant. Jute fiber reinforced green composites were manufactured using preheated chopped jute fiber and maleic anhydrate grafted polypropylene in the hot press machine at a temperature of 180°C and a pressure of 40 kN. Both raw and chemically treated jute fibers at three levels of fiber loading (20, 25 and 30 wt%) were utilized during composite manufacturing. Micro-structural analysis and mechanical testing of the manufactured green composites were subsequently carried out. Chemically treated jute fiber composites showed an improvement in mechanical properties as compared to the maleic anhydrate grafted polypropylene. The impact property was not significantly affected by chemical treatment. At room temperature water uptake increased with fiber weight fraction, while water retardant jute fiber composites absorbed more water as compared to the other composites. The rot retardant treated jute fiber composites had the best set of mechanical properties among all manufactured composites. SEM observation of the fracture surface clearly showed that control and rot retardant jute fiber reinforced green composites had more fiber pull out as compared to fire retardant and water retardant jute fiber reinforced green composites. This indicates better adhesion between the matrix and fiber in case of the fire retardant and water retardant green composites. Chemically treated jute fiber reinforced green composites could be popular as a substitute of plastic in house hold sectors as a moderate load bearing component.

In this study, a polymer composite is made using chemically treated jute fiber and waste floor tile powder as an alternative source for roof tile application. The wear qualities were examined at various ages, and the outcomes were optimized. In order to improve the wetting properties of the jute fiber, it was chemically treated. MINITAB software was used to develop Taguchi method parameters such as jute fiber percentage, waste tile powder percentage, and NaOH chemical treatment using the MINITAB software. It was determined that hardness was the most important characteristic in terms of wear properties after the specimens were subjected to ageing and abrasion wear testing and hardness tests were carried out as per normal protocols. As a result of the waste tile powder addition, the surface and core pore formation rates were reduced and the wear index rates were low. Jute fiber with 15%, 9% tile powder, and 5% NaOH treatment were found to have the lowest wear index of the other specimen compositions tested, according to the wear index. Specimen made with 5% jute fiber addition, 9% tile powder inclusion, and 10% NaOH treatment, on the other hand, had more hardness. Degradation of the fibers and delamination are side effects of the ageing process. The wear resistance of the surface was increased by the use of waste tile powder.

Degumming of pre-chlorite treated jute fiber was studied in this paper. The effects of sodium hydroxide concentration, treatment time, temperature, sodium silicate concentration, fiber-to-liquor ratio, penetrating agent TF-107B concentration, and degumming agent TF-125A concentration were the process conditions examined. With respect to gum decomposition, fineness and mechanical properties, sodium hydroxide concentration, sodium silicate concentration, and treatment time were found to be the most important parameters. An orthogonal L9(34) experiment designed to optimize the conditions for degumming resulted in the selection of the following procedure: sodium hydroxide of 12g/L, sodium silicate of 3g/L, TF-107B of 2g/L, TF-125A of 2g/L, treatment time of 105 min, temperature of 100°C and fiber to liquor ratio of 1:20. The effect of the above degumming process on the removal of impurities was also examined and the results showed that degumming was an effective method for removing impurities, especially hemicellulose.
