In order to suppliment the previous report the blended yarns of cotton and rayon s. f. with each different length have been produced. The results obtained are as follows:
(1) As regards interaction, the difference of fibre denier in any different fibre length and the difference of fibre length in similar fibre denier have greater influence independent of the kind of fibres.
(2) Both the yarn evenness and the blend irregularity are greater for two different lengths of component fibres than for same lengths, but the causes of both irregularities do not necessarily coincide.
