Sustainable development of three distinct starch based bio-composites reinforced with the cotton spinning waste collected from fiber preparation stage.

Composites are new materials that combine two or more distinct components with diverse properties to create a new material with improved properties. The goal of this endeavor was to use fiber preparation wastes, or waste from cotton spinning mill blow room and carding, to produce bio composites based on starch. The matrix was prepared using the starches of potatoes, maize, and arrowroot, and any remaining reinforcing material was used.

Evaluation of physical and mechanical characteristics of three-thread fleece knit fabric for their structural changes.

The aim of this research is to explore the variations that can arise when three-thread fleece (3- TFL) fabric is manufactured with the same yarn type, count, stitch length, knitting machine gauge, and diameter but in different structural configurations. The physical and mechanical properties of 3-TFL fabrics vary depending on their structural construction, which has a significant impact on their intended usage. For this study, four distinct types of three-thread fleece fabric structures were developed titled straight, three-butt diagonal, four-butt diagonal, and double tuck 3-TFL.

An approach to improve the existing ribbon retting of jute fibre using concrete tank and natural catalyst.

The ribbon retting method has been developed as a remedy for the issues associated with the conventional water retting method. But this method has not yet gained popularity among jute growers due to the unavailability of catalyst, inadequate training and lack of interest of farmers. The study deals with the improvement of the existing ribbon retting process by using a concrete tank with or without fermented soybean as a natural catalyst in different proportions.

Due to their numerous applications and eco-friendly behavior, natural cellulosic fibers are in greater demand every day. In this article a new natural fiber extracted from the creepers of with the help of 5% NaOH retting process.

Comparison of different New Radio (NR) waveforms for wireless communications.

New Radio (NR) waveforms of existing wireless communication systems need further improvement in order to support future wireless communications. NR is the radio interface technology proposed by the 3rd Generation Partnership Project (3GPP) for 5G. Prototype Filter (PF) of NR plays a vital role in performance improvement of wireless systems.

Damping under Varying Frequencies, Mechanical Properties, and Failure Modes of Flax/Polypropylene Composites.

This work investigates the effects of fibre content, fibre orientation, and frequency on the dynamic behaviour of flax fibre-reinforced polypropylene composites (FFPCs) to improve understanding of the parameters affecting vibration damping in FFPCs. The effects of fibre content and fibre orientation on the mechanical performances of FFPCs, along with fracture characteristics, are also investigated in this study. Laminates of various fibre contents and orientations were manufactured by a vacuum bagging process, and their dynamic and static properties were then obtained using dynamic (dynamic mechanical analysis (DMA) to frequencies of 100 Hz) and various mechanical (tensile and flexural) analyses, respectively.
