An alternate design that uses a needleless spinneret to overcome the disadvantages of both needle-based and free-surface electrospinning, whilst controlling the Taylor cone formation is credited to Revolution Fibres Ltd [40], who scaled up this process to achieve continuous production of nanofibres from less than 100 nm to sub-micron range with more than 30 varieties of polymers. Elmarco developed similar techniques with coated wires as spinneret and recently Stellenbosch University has developed a regenerating bubble method [41] as an alternative to needle-based electrospinning. 

Revolution Fibres nanofibre acoustic products Phonix can be tailored and customized to target a range of frequency levels. Its innovative acoustic nanofibre membrane Phonix was able to achieve improved sound absorption by in combination with IQ Commercial s furniture foam. Figure 11.6a shows the sound absorption efficiency of nanofibre at high frequencies. The two companies collaborated successfully and launched the Return Focus Pod for sound absorbing office work stations for improved client privacy and efficient working desk for office users (Fig. 11.6b). 

The cosmetics and skin performance sector is another application where nanofibres are emerging, offering instantaneous delivery nutrient mechanism to the skin. In this mechanism, the nanofibre membrane acts similar to woimd care but instead the nanofibres are usually water soluble or biodegradable and contain healthy nutrients for the skin. Revolution Fibres Ltd (New Zealand) has developed nutrient infused marine collagen nanofibres called ActiVLayr . This unique water soluble collagen nanofibres act as a carrier to deliver natural nutrients to the skin to improve performance of the skin. The active content can be modified and customized in order to target certain skin benefits [40]. 

It is almost paradoxical that in the history of mankind composite materials were earlier used than their "homogeneous" rivals. The earliest "engineering materials" were bone, wood and clay. Wood is a composite of matrix lignin and a cellulosic reinforcement bone is a natural composite where fibres of hydroxyapatite reinforce the collagen matrix and the oldest building material was adobe clay as a matrix, reinforced by vegetable fibres. After the industrial revolution other composites were added reinforced rubber, reinforced concrete, reinforced asphalt, etc. 

Gould and Roberts carried out a test on a ball-bearing with a Duroid PTFE/glass fibre/molybdenum disulphide retainer and with a sputtered molybdenum disulphide film on the tracks. The bearing completed the 2x10 revolution test at 17 K (-256°C), but the sputtered film was then found to have been removed and replaced by PTFE, It is not clear whether this result represents any fundamental problem with sputtered films at low temperatures.

With the industrial revolution, textile manufacturing turned into industry and the requirements for a fibre to be used for textiles became more exactly defined. For use in textiles a fibre should have properties whieh render it spinnable and wearable, enumerated below ... 

During the last century there has been a turn away from natural fibres towards chemically obtained materials, mostly derived from petroehemieals. This change was a result of the technological revolution and the short-term... 

In the filament winding process a mandrel is rotated upon which are wound reinforcing fibres which have been impregnated with resin. The fibre is controlled by an applicator which traverses the length of the mandrel as it rotates, thus building up the laminate thickness. A surface of revolution is produced, the type (cylinder, cone, etc.) depending on the mandrel shape. Variations include extra axes of movement to allow the winding of domed ends, spheres, conical shapes, etc. 

In the case of natural fibre reinforced polymer composites,in 1996 this material was used for making aeroplane seats and fuel tanks. The last decade has been used widely because of biodegradability and high specific properties. Currently, nanobiofibre composites are also provided for material revolution in technical application which is taking place in the automobile and packaging industrial. 

In both versions of the surgery, it is obvious that a deformed circle (or a doubled circle r ) describe a two-dimensional disk with two holes. Moreover, after one revolution along the circles 5, this disk returns to its initial place, but the two holes of this disk exchange places. We have obtained none other than the manifold fibred over the base with fibre JV. Let be a critical circle of index 2 or 0. Consider its tubular neighbourhood U(S ), Since / is a Bott function, it follows that U S ) fibres into tori which contract onto the circle and are level surfaces of the function /. Since these are Liouville tori, the integral trajectories of the system v lie on them. Then the circle 5 is obviously stable. 

We vary the drum revolution (multiple stage) to minimize damage to the fibres as a result of optimum energy feed-in. 

However, it was the Industrial Revolution, commencing about 1760, which resulted in the establishment of a fully fledged chemical industry. The establishment of a large number of textile mills created a demand for a range of chemicals used in the processing of fibre into finished cloth. These included alkalis, acids, bleaching agents, mordants and dyes.
