Fabrication and characterization of antimicrobial wound dressing nanofibrous materials by PVA-betel leaf extract.

This present study involves the formation and investigation of the characteristics of a fabricated mat from a PVA-betel leaf mixture. Under ideal processing parameters, nanofibrous mat is synthesized from the PVA-betel leaf blended solution by using the electrospinning technique. Afterwards, the produced nanofibrous mat is assessed for its thermal, antibacterial, morphological, moisture management and chemical interaction behavior using thermogravimetric analysis (TGA), antibacterial assay, scanning electron microscope (SEM), moisture management tester (MMT) and Fourier-transform infrared spectroscopy (FTIR) respectively.

Ecofriendly pretreatment of cotton fabrics by ultrasonication and reusing bath chemicals.

The textile industries of Bangladesh contribute significantly to the country's economy, accounting for more than 40% of total annual export. The quest of new technologies for efficient water and energy use in cotton knit dyeing could result in significant water savings and improve environmental sustainability. Textile wet processing consumes a lot of utilities (water and energy), and the water generates a lot of waste, which enhances chemical consumption and effluent management costs.
