Two cottons differing by 4.2 mm in their 2.5 % span lengths (30.9 and 26.7mm) and by 6.1 cN/tex in their zero gauge bundle tenacities were blended and the resultant yarn and fabric properties measured.
An apparatus is described which simulates the withdrawal action of a rectilinear comb, allowing the measurement of the necessary to withdraw a tuft of fibres from a pin bed at high speed.
