Applications of microfibres and micro-filaments [6]
Microfibres are characterised by advantageous properties such as pleasant softness of handle, good
draping qualities, lustre, bulk and outstanding surface properties. At the start of development, the
researchers searched for suitable fields of application for their microfibres, since they had properties
which had not yet existed in previous clothing and technical textile concepts.
Synthetic game leather and imitation leather [6]
When it was proved that natural game leather collagen fibres have diameters within the range of 4
micrometers, imitation game leather and artificial leather could be developed with great success, since
the new microfibres equated with this level in dimensional terms.
Synthetic game leather and leather products are today produced industrially in Japan by impregnating
nonwovens produced from PET, PA or PAN microfibres with polyurethane (UP). These products offer
outstanding advantages compared to natural leather and game leather in terms of uniformity,
dimensional stability, ease of care, colour fastness, and low mass.
