“…weaving). This article is a contribution to solving this issue and thus adds findings from previously published works in the field of theoretical and experimental analysis of the mechanical properties of nanofibres [see [1][2][3] or the method of their production [see [4][5][6][7][8][9][10], which affects the mechanical properties of nanofibres.…”

“…In this case, this study is a direct follow-up of the publication [11], which describes in detail the structure of this equipment, the procedure employed in the realisation of tests and the method of processing measured data, including the deduction of relations for calculation of dynamic modules and loss angles. Therefore, we indicate here the resultant relations for the calculation of the said parameters only (see relations (1) and (2)):…”

This study deals with a comparison of mechanical properties of a conventional yarn and a textile from nanofibres. The conventional yarn represents the textile objects with high degree of orientation of fibres and the textile from nanofibres represents the textile objects with low degree of orientation of fibres. The theoretical section is concerned with the issue of internal structure of plied yarn and resulting differences in the orientation and straightening of fibres and in utilisation of deformation properties of fibres in comparison to the referred nano textile. The experimental section describes the manner of realisation of both static and dynamic tests of conventional yarn and strips of nanofibres. The results show differences in the mechanical properties of conventional yarn and textile strip from nanofibres under static and dynamic loading conditions. The processing technology of conventional yarn has been verified in the long term. But textiles from nanofibres are a relatively new material and mechanical properties of the detected differences point out possible problems with their behaviour during standard technological processes.

“…They observed highly oriented CNTs within the nanofibres and attributed this to the structural formation during the electrospinning process and the slow relaxation of CNTs [109]. Using a similar setup, Jose et al [137] also fabricated aligned electrospun Nylon-6 nanofibres containing surface modified MWNTs. The MWNTs showed high degree of alignment in the nanofibres.…”

“…Recently, Yoon et al [150] reported enhancement in mechanical strength of CNT reinforced nanofibres caused by better nanotube-polymer adhesion and good dispersion of SWNT because of the plasma treatment of nanotubes. Uniform dispersion of amino functionalised MWNTs and nanotube alignment in nylon 6 led to increased mechanical properties of electrospun MWNT/nylon-6 nanofibre mat [137] [151]. The upper limit of CNT concentration in electrospun nanofibres is also confined by the extent of CNT dispersion.…”

“…The materials used and the preparation conditions influence the shape of the ultrafine fibers formed. To date, several kinds of electrospun fibers have been prepared, including ultrafine fibers with beads on the string [5,6], fibers with ribbon cross-sections [7,8] and in particular, fibers with round cross-sections [9][10][11]. Furthermore, electrospun fibers with nanopores on the fiber surface have been prepared and characterized [12][13][14][15].…”

Electrospinning is a well-known process for producing submicrometer fibers, which have wide applications in many fields, especially in tissue engineering scaffolds and drug-delivery systems. This paper presents the formation of drug-loaded electrospun twin fibers. The correlations between the twin fiber formation and the polymer materials or the loaded drugs were studied by using poly(l-lactide) and poly(l-lactide-co-glycolide) as electrospinning materials, and rifampin and paclitaxel as loaded drugs. Scanning electron microscopy showed that the formation of twin fibers is significantly affected by the loaded drug but not the polymer material. A possible reason for twin fiber formation was analyzed. Electrospinning is a well-known process [1-4] for producing micro-or nanofibers for use as tissue engineering scaffolds, drug controlled-release carriers, filtration, and biosensors. The materials used and the preparation conditions influence the shape of the ultrafine fibers formed. To date, several kinds of electrospun fibers have been prepared, including ultrafine fibers with beads on the string [5,6], fibers with ribbon cross-sections [7,8] and in particular, fibers with round cross-sections [9][10][11]. Furthermore, electrospun fibers with nanopores on the fiber surface have been prepared and characterized [12][13][14][15]. Recently, Varesano et al.[16] fabricated crimped polymer nanofibers by air-driven electrospinning.One of the most important medical applications of electrospun ultrafine fibers is their use as drug controlled release carriers. Although there are limited studies on this application, it has attracted increasing attention [17][18][19][20][21]. For example, Tungprapa et al. [17] examined the release characteristics of four model drugs from drug-loaded electrospun cellulose acetate fiber mats. The results showed that the release rate of the four model drugs from the drugloaded electrospun cellulose acetate fiber mats were greater than that from the corresponding as-cast films. Zeng and co-workers [18,19] explored the preparation of rifampinloaded electrospun PLLA fibers and later studied the influence of the drug compatibility with the polymer solution on the release kinetics of such electrospun fiber formulations. It showed that the burst release of the drug can be avoided by using compatible drugs with polymers and that drug release can follow nearly zero-order kinetics due to degradation of the PLLA fibers in the presence of proteinase K. This paper presents the formation of drug-loaded electrospun twin fibers. The correlations between the twin fiber formation and the polymer materials used for electrospinning or the loaded drugs were studied and a possible mechanism for twin fiber formation analyzed. The results have great significance for designing and preparing new drug controlled-release systems and for further study into the mechanisms of drug controlled release.
