“…20 The electro spinning of poly-L-lactide, polycarbonate, polyvinylcarbazole 21 and polyvinylpyrolidone 22 were carried out by Bognitzki and co-workers. The electro spinning of nylon6, cellulose acetate, 23 polyacrylonitrile (PAN), 24 polyurethane, 25 polycarbonate, 26 polybutylenes succinate (PBS) 27 and polyvinyl alcohol (PVA) 28 has also carried out. Baumgarten had earlier electrospun acrylic resins dissolved in dimethylformamide.…”

Electro spinning is a simple and versatile technique applicable to a wide range of polymers and solvents for the production of materials in nanometer scale. The nano fibrous materials produced by electro spinning process exhibit novel and significantly improved physical, chemical and biological properties. The small fibre diameter and the porous structure of the electrospun surfaces enable them for a wide range of applications such as wound dressing, tissue engineering scaffolds, vascular grafts, filters, membranes and sensors. In this article the principle, setup, materials used and the factors affecting the electro spinning process have been described. Also the properties & applications of electrospun fibres and the limitations & future scope of electro spinning process have been highlighted.

“…The nanofiber yarn had a maximum twist angle of 19.76° (Yousefzadeh et al). Dabirian et al (Dabirian et al, 2007) reported a method of continuous nanofiber yarn formation through the manipulation of the electric field. A negative bar and a negative surface were placed within the electric field to direct the electrospinning jet.…”

“…In some instances, twisting nanofibre bundles (Fennessey & Farris, 2004;He, Huang, & Han, 2009) or strip cut nanofibre webs (Uddin, Ko, Xiong, Farouk, & Capaldi, 2009;Zhou, Fang, Wang, & Lin, 2012) after electrospinning have been reported. Continuous nanofibre yarns have also been produced by direct electrospinning using liquid bath (Khil, Bhattarai, Kim, Kim, & Lee, 2005;Smit, Bűttner, & Sanderson, 2005;Teo, Gopal, Ramaseshan, Fujihara, & Ramakrishna, 2007;Yousefzadeh, Latifi, Teo, Amani-Tehran, & Ramakrishna, 2011), solid surface (Dabirian & Hosseini, 2009;Dabirian, Hosseini, & Hosseini Ravandi, 2007;Dabirian, Ravandi, Sanatgar, & Hinestroza, 2011;Hajiani, Jeddi, & Gharehaghaji, 2012), and funnel or tube Ali, Zhou, Wang, & Lin, 2012;He, Qi, Zhou, & Cui, 2014) as collector.…”

Nanofibres prepared by electrospinning typically have randomly oriented fibrous structure. They have large surface-tovolume (or weight) ratio and excellent porous characteristic, which have shown enormous potential in diverse applications. However, electrospun nanofibres are often prepared in the form of randomly orientated fibrous web, which are fragile and difficult to be tailored in fibrous structures. Herein, we demonstrate a novel yarn electrospinning method which uses a rotating ring collector to convert newly electrospun nanofibres directly into a continuous yarn. The use of ring collector separates the yarn formation from the electrospinning zone. The deposition of later-spun nanofibres to the inner surface of fibrous cone eliminates hooked or curled nanofibres in the final yarn. The effects of polymer concentration and operating parameters on nanofibre and yarn morphology, diameter and the ring collector on yarn twist feature were examined. The nanofibre yarns had a surface twist angle up to 54.4°, and tensile strength as high as 93.6 MPa (elongation at break 242.6%). Increasing twist levels improves tensile strength and strain values.
