Abstract: The fancy effects formation using one process and hollow spindles has been studied. A composite design has been formulated and three variables, namely delivery speed of fancy yarn, rotational speed of hollow spindle and supply speed of effect component, considered to understand how technological parameters influence the formation of fancy effects, like closed loop, opened loop, loop-knot, plain knot and knot made from various loops, and their combinations. Procedure of counting the effects per unit length using twist tester and stereomicroscope for precise establishment of fancy effect is also accomplished. It is observed that the technological parameters contribute significantly to structural effects formation. On the basis of graphical pictures of the mathematical model that express the relationship between the number of effects of plain knot-knot made of various loops per unit length of fancy yarn and all the parameters of technological process of production, the particular interrelations have been investigated and the received model could be used to predict the number of fancy effects of certain nature, to control the effect formation process, and to enlarge the base of information needful for yarn design.
