Abstract
A study has been made of the behaviour of singles worsted yarns of different fibre configurations when tested for strength at a constant rate of loading on an Uster automatic strength tester. The main characteristics observed could be described consistently in terms of the ‘effective linear density’ and ‘effective twist factor’ for the yarns. For normal values of this twist factor, the standard deviation of the strength of the yarn appears to be proportional to the square root of the effective linear density, expressed in tex units. Data are also given that permit the mean percentage elongation to rupture to be estimated.
