On the other hand, nanofibres help stimulate living tissues to repair themselves in various parts of the
human body, such as cartilage, blood vessels, bones and so forth, due to diseases or wear and tear.
Nanofibres are about 10,000 times smaller in diameter than the width of a human hair, but of greater
dimentions than a typical cell, which is of the order of one micrometer depending of the type of cell.
Nanofibres have a large surface area in comparison to their size. Smaller than usual fibres, they allow
cells to adhere to them better, speeding up the healing process.
Another advantage of using nanofibres to grow tissues stems from the fact that natural scaffolds
themselves are of fibres in the nanometre-size range. In another words, nanofibres are closer replicas
of the natural environment of the cells than micron-range fibres.
Construction applications [23]
Composites are multilayer materials consisting of different layers with distinct properties in each layer.
The composite is constructed in order better to utilise a combination of properties from different layers.
Polypropylene and bi-component microfibres can be very important components of fibre-reinforced
composites, as they function not only as a reinforcing element, but also as a binder fibre between the
individual layers. Polypropylene and bi-component microfibres are used in many different composite
