This research aims to study the spinnability of pristine PALF and PALF blended cotton using the existing spinning machines. Apron draft ring spinning frame and flyer jute spinning frame were used to produce 100% PALF yarn and the yarns count were found 121 tex and 138 tex separately. Besides, 90:10 and 80:20 cotton-PALF blended 30 tex yarn spun in a cotton spinning system with different twist factors. With both yarns, two samples; 1/1 plain and 3/1 twill fabrics, were fabricated through equal density. For plain and twill fabric, PALF yarn of 121 tex and 138 tex were used in the warp way, respectively and PALF blended cotton yarn of 60 tex was used in the weft way. Through the study, physio-mechanical properties of the samples were explored and FTIR & XRD patterns were analyzed to perform the task for diversified use as an ultimate fiber in industrial and domestic purposes.

MXenes, a group of two‐dimensional (2D) metal carbides and nitrides, have emerged as promising electrode materials for supercapacitors. This is primarily attributed to their inherent metal‐like electrical conductivity, layered structure, surface redox reactivity, and superior pseudocapacitance through surface functional groups. Owing to its promising features, this material suffers from low mechanical strength, restacking, and unprecedented oxidation. As a result, balancing the electrochemical performance becomes challenging, eventually impeding its potential applications in lightweight, flexible supercapacitor applications. Recent strategies are centered on lighter and more stable filler materials to tackle these issues. Among these, cellulose is considered one of the most effective renewable materials because of its biocompatibility, thermal stability, high surface area, and mechanical reinforcement. Moreover, nanocellulose is capable of hosting other functional materials on its reactive surfaces, ensuring better ion accessibility, and can be used as an electrolyte separator membrane. This review paper aims to provide a comprehensive overview of recent advances in the fabrication strategy, deterministic parameters for capacitive energy‐storage devices, electrochemical behavior, and the performance of MXene/cellulose‐based electrodes in its three‐dimensional aspect (1D, 2D and 3D) for supercapacitor application. Lastly, this review will outline the challenges and prospects of MXene/cellulose‐based composite electrodes in real‐life supercapacitor applications.

The by-products of pineapple fruits such as stems and leaves are generally considered as agro-wastes, but these wastes can be used as raw materials for reinforced fibre, yarn and eventually in fabric formation. Unlike PALF, Jute is a bast fibre and one of the main cash crops of Bangladesh, which has already proven as a versatile fibre. In this study, the spinning performance of PALF such as fineness, bundle strength, breaking tenacity and breaking elongation properties have been studied and compared with jute. It showed that the physical and structural characteristics of PALF were similar to jute fibre, even in some cases PALF is better. Another study was done in which it was found that surface characteristics like color strength (K/S value), whiteness, yellowness, and brightness signifies that the PALF yarn is almost similar in comparison with jute yarn. Besides, Pineapple Leaf Fibres contained relatively greater diameter compared with that for jute fibre and consequently, the quality ratio value of yarn for PALF was much smaller than that of jute yarn. Finally, a comparative decision is made; that the use of PALF can be a sustainable replacement toward an economy based agricultural solution for Bangladesh.
