Computational fluid dynamics modeling in yarn engineering

Author: Patanaik, A ; Anandjiwala, R Date: Jul 2011 This chapter deals with the application of computational fluid dynamics (CFD) modeling in reducing yarn hairiness during the ring spinning process and thereby “engineering” yarn with desired properties. Hairiness significantly affects the ... Read more
CSIR facilities geared to support the Biocomposites Centre of Competence

Author: Anandjiwala, R Date: Oct 2012 Over the past few years, the CSIR has made a significant investment into fibres and biocomposite research and infrastructure at its Port Elizabeth campus. The Department of Science and Technology (DST) has invested approximately R10.8 million ... Read more
Development of thermoresponsive poly(propylene-g-N-isopropylacrylamide) non-woven 3D scaffold for smart cell culture using oxyfluorination-assisted graft polymerisation

Author: Chetty, AS ; Vargha, V ; Maity, Arjun ; Moolman, FS ; Rossouw, C ; Anandjiwala, R ; Boguslavsky, L ; Mancama, Dalubuhle T ; Focke, WW Date: Feb 2013 Growing cells on 3D scaffolds is far superior to the conventional 2D monolayer culture method. In this study, a novel 3D thermoresponsive poly(propylene-g-N-isopropylacrylamide) (PP-g-PNIPAAm) nonwoven fabric (gNWF) was developed for cell ... Read more
Enhancement of mechanical properties and interfacial adhesion by chemical odification of natural fibre reinforced polypropylene composites

Author: Erasmus, E ; Anandjiwala, R Date: Nov 2008 Natural fibres are often used for reinforcing thermoplastics, like polypropylene, to manufacture composite materials exhibiting numerous advantages such as high mechanical properties, low density and biodegradability. The mechanical properties ... Read more
Environmental friendly method for the extraction of coir fibre and isolation of nanofibre

Author: Abraham, E ; Deepa, B ; Pothen, LA ; Cintil, J ; Thomas, S ; John, Maya J ; Anandjiwala, R ; Narine, SS Date: Feb 2013 The objective of this work was to develop an environmental friendly method for the effective utilization of coir fibre by adopting steam pre-treatment. The retting of the coconut bunch makes strong environmental problems which can be avoided ... Read more
Extraction of nanocellulose fibrils from lignocellulosic fibres: a novel approach

Author: Abraham, E ; Deepa, B ; Pothan, LA ; Jacob, M ; Thomas, S ; Cvelbar, U ; Anandjiwala, R Date: Jun 2011 The objective of this work was to develop a simple process to obtain an aqueous stable colloid suspension of cellulose nano fibrils from various lignocellulosic fibres. For the preliminary analysis we have studied three different fibres: ... Read more
Flax fiber reinforced PLA composites: studies on types of PLA and different methods of fabrication

Author: Kumar, R ; Anandjiwala, R Date: May 2011 Natural fibers are used as reinforcement material for number of thermoplastic/thermoset polymers. The interest in using polylactic acid (PLA) as thermoplastic matrix to produce composites completely from 100% renewable resources has increased ... Read more
Flax reinforced thermoset composites from polyfurfuryl alcohol

Author: Kumar, R ; Anandjiwala, R Date: Sep 2009 Water insoluble poly(furfuryl alcohol) (PFA) is an unexplored thermosetting resin which is synthesized from water-soluble furfuryl alcohol (FA). Commercially available FA has very low viscosity (6.9-7.0 cts at 25°C) and it is obtained from ... Read more
Functionalisation of polypropylene non-woven fabrics (NWFs): Functionalisation by oxyfluorination as a first step for graft polymerisation

Author: Vargha, V ; Chetty, A ; Sulyok, Z ; Mihaly, J ; Keresztes, Z ; Toth, A ; Sajo, I ; Korecz, L ; Anandjiwala, R ; Boguslavsky, L Date: Oct 2011 Surface oxyfluorination had been carried out on polypropylene non-woven fabric (PP NWF) samples of different morphologies and pore sizes. The modified surfaces were characterised by Attenuated Total Reflectance Fourier Transform InfraRed ... Read more
Melt-spun polylactic acid fibers: effect of cellulose nanowhiskers on processing and properties

Author: John, Maya J ; Anandjiwala, R ; Oksman, K ; Mathew, AP Date: Apr 2012 Bio-based continuous fibers were processed from polylactic acid (PLA) and cellulose nanowhiskers (CNWs) by melt spinning. Melt compounding of master batches of PLA with 10 wt % CNWs and pure PLA was carried out using a twin-screw extruder in ... Read more
Physicomechanical properties of nanocomposites based on cellulose nanofibre and natural rubber latex

Author: Abraham, E ; Deepa, B ; Pothan, LA ; John, Maya J ; Narine, SS ; Thomas, S ; Anandjiwala, R Date: Nov 2012 Cellulose nanofibres (CNF) with diameter 10–60 nm were isolated from raw banana fibres by steam explosion process. These CNF were used as reinforcing elements in natural rubber (NR) latex along with cross linking agents to prepare nanocomposite ... Read more
Potential of biocomposites for economic development in Southern Africa

Author: Anandjiwala, R Date: Oct 2012 In this presentation the author presents the rationale and potential of research and product development in biocomposites in context to economic development in South Africa. Read more
Smart 3D cell culture using a thermoresponsive PP nonwoven scaffold

Author: Chetty, A ; Rossouw, C ; Ntsangani, L ; Moolman, S ; Van Wyk, K ; Mancama, Dalubuhle T ; Anandjiwala, R ; Boguslavsky, L ; Vargha, V Date: May 2011 In this paper the grafting method will be described and characterisation of the smart PP-g-PNIPAAm scaffolds by fourier-transform infrared, scanning electron microscopy, x-ray photoelectron spectroscopy, differential scanning calorimetry, ...
