A Multicriteria Decision Aid Approach on Navel Selection Problem for Rotor Spinning

Abstract

In studies about optimization of rotor spinning machine parameters, generally classical statistical methods have been used; the priorities and preferences of the yarn producer about yarn properties to get the desired end product characteristics have not been taken into consideration. However, machine part selection from possible alternatives with different properties and performance levels about yarn quality is a difficult task and inherently a multicriteria decision-making problem. In this study, it is proved that application of a multicriteria decision aid method, ELECTRE III, can provide valuable assistance in reaching acceptable solutions in order to select the appropriate navel for Ne 12 rotor yarn spun to weave denim fabric. In experimental part of the study, Ne 12 rotor yarns were spun by using ten navels having different technical properties and their quality parameters were analysed with ELECTRE III.

Multi-objective optimization of the textile manufacturing process using deep-Q-network based multi-agent reinforcement learning

“…But it is very difficult to decide in the scenario of a textile manufacturing process owing to the complicated application of a wide range of dependent and independent parameter variables in a very long chain of the textile processes [1]. Meanwhile, the optimization of a textile manufacturing process in terms of scenario solution always involves the consideration of multiple objectives as the performance of a textile manufacturing process generally is governed by a few conflicting criteria with different significance [2].

Ranking Alternatives in Rotor-Spun Knitting Process Using Extended VIKOR on Interval Data

“…Yarns drawn from the rotor groove make a 90 0 turn inside the nozzle. The rotation of the yarn around the inner walls of the nozzle creates additional false twists on the yarn between the rotor groove and yarn draw-off [2,3]. Furthermore, false twist insertion is a function of the friction between the yarn surface and extractive nozzle.…”

Effect of Some Navels on Properties of Cotton/Nylon66 Blend (1 : 1) Rotor Spun Yarn and Wrapper Formation: A Comparison between Rotor and Ring Spun Yarn

“…Javadiyan et al [8] worked on seven different nylon/cotton blend ratios and reported that by increasing the nylon fiber blend ratio, the yarn elongation, abrasion resistance, tensile work of rupture, and hairiness significantly increase, whereas yarn tensile modulus decrease. Navels differ in their material, forms, number of grooves, existence of fluted inserts, length of ceramic parts, and grooves [9]. Smooth navels often give better yarn characteristics; the yarn is more resistant to rubbing and has good heat conductivity and generally less false twist; grooved navels can operate at lower twist levels; the running performance is better because of the greater false twist effect but hairiness does increase; ceramic navels with 4-6 grooves have proved advantageous in the spinning of blended yarns and fibers that are not strongly sensitive to heat [10].…”
