Submicron/nanofibres possess great potential for application in different areas because of their amazingly high surface area-to-weight ratio. The demand for fabrication of such fibres on a huge scale is increasing with the fast improvement of nanotechnology. Traditionally, nanofibre fabrication methods have intrinsic faults, limiting their application in industry. Solution blow spinning (SBS) is a viable option for producing adaptable and conformable submicron/nanofibre mats on a variety of surfaces. The technique can be employed to produce submicron/ nanofibres with only a simple commercial airbrush, a concentrated polymer solution, and a compressed gas source. It depends on the high velocity of decompressed air that allows the rapid stretching and evaporation of the solvent from a polymeric solution jet at the outlet of the concentric nozzles system. Along with recent advancements, the importance and drawbacks of the solution blow spinning system in comparison to other methods, such as electrospinning and melt blowing, are briefly discussed. Furthermore, the mechanisms of co-axial SBS spinning and micro SBS spinning system for submicron/nanofibre fabrication are also described. Drawbacks and research challenges of SBS are also addressed in this paper.
Ligno-cellulosic natural fiber like Banana can be acclimated to manufacture hybrid or union fabric with mostly used jute fiber which can get colossal popularity as a wearable product because of the health and hygiene issues. Banana fibers, extracted from the sheath, can be utilized for manufacturing fiber, can diminish the pressure on the jute fiber. It will be very frugal, and ineluctably it will be a great opportunity to blend it with the other natural fiber. In this study, a Jute-Banana hybrid fabric (JBHF) was developed by using Jute yarn (12 Ne, in warp) and Banana yarn (18 Ne, in weft). In order to evaluate physico-mechanical properties of naturally dyed Jute-Banana hybrid fabric, different tests like Stiffness, Thickness, Tensile strength, Tear strength, Drape and Crease recovery were conducted which provided satisfactory results. Colorfastness to wash, water, rubbing and perspiration of naturally dyed Jute-Banana hybrid fabrics (JBHF) also provided acceptable outcomes. FTIR test also provided the confirmation of this two fibers and Spectrophotometer was used to illustrate the dyeing quality. It was an endeavor to minimize the dependency on a single quality fiber and find an alternative way to prepare the hybrid fabric by blending two different quality natural fibers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
