More advantages at high short fibre ratio
The advantages with the yarn characteristics are clearly
far more distinctive with a raw material that has a high
short fibre ratio, as due to the pin the short fibres are
significantly better guided than previously. Thus the
choice of fibre is simplified. A raw material with a slightly
higher short fibre content can achieve comparable yarn
values. Also yarns of count Ne 30 and finer showed a
