Spinning preparation parameters selection for rotor spun knitted fabric using VIKOR method of multicriteria decision-making

Selection of spinning preparation parameters which affects properties of the final yarn and subsequent process is a multicriteria decision-making problem. Different statistical methods and multicriteria approaches have been used to solve such kind of problems. This paper presents a new multicriteria decision-making technique to select the suitable drawing frame parameters for 30Ne rotor spun yarn intended to be used for weft knitting process. Three important variables in drawing frame including distance between back and middle rolls, delivery speed, and break draft were considered. Their performances were evaluated on the basis of seven quality parameters of the 48 rotor spun yarns using VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method. The final ranking of the parameters was elicited in accordance with this procedure. Consequently, the stability of the proposed final ranking was verified after sensitivity analysis.
