Each step in the manufacturing proc-ess, such as twisting, spinning, weaving, knitting etc., causes tension in fiber and yarns. Yarns tend to snarl in order to re- lax themselves and get rid of this tension. Tension and snarling are likely to lead to problems in the following manufactur-ing processes [2]. The purposes of con-ditioning and heat-setting (twist-setting) are to relax yarns, to
