In this endeavor hair-length groups desired (≥1, ≥2 and ≥3 mm) and undesired (< 3 mm) S3 hairs are predicted in p/w yarns. The DRF yarns have been produced as per experimental plan developed by using box and behnkens design for three levels selecting wool fiber length, TM and strand spacing as variables. The conventional double yarns produced by all three fiber length at TM 2.25 were compared. The results elicit that variables have influence on hairs of all groups. The hairs (all groups) are lesser in DRF yarns than conventional yarns produced by different fiber length comparatively.

All groups hairs decreases as fiber length increases. The 2 mm and 3 mm hairs are reduce as TM increases. The 1 mm, 2 mm and 3 mm hairs are increases however S3 hairs very minor reduce when spacing increase. The 1 mm hairs numbers are prominent. The combined effect of TM and strand spacing is visible as both variables are increases the hairs of 1 mm, 2 mm and S3 are increases however 3 mm are decreases. The hairs were found lowest 1 mm 639, 2 mm 215, 3 mm 215 and S3 170 and highest 1 mm 840, 2 mm 283, 3 mm 245 and S3 195 respectively.
