Sustainable Denim Yarn: Quality-Cost Analysis and Analytic Hierarchy Process (AHP) Optimization

Abstract

Due to its increasing importance, the circular economy concept has encouraged spinners to produce sustainable products. We investigated the proper use of recycled fiber, from spinning waste, as a low cost and sustainable raw material to spin blended yarn. The increasing ratio of recycled fiber is known to affect the final yarn quality. Compromise between cost and quality of yarn prepared from recycled fibers was approached using the analytic hierarchy process (AHP). Results show that AHP was a suitable approach to convert a subjective assessment (expert opinion) for an objective decision maker. A mixture of 80% recycled fibers and 20% virgin cotton (Malian) was selected as an optimal raw material to spin blended yarn with, obtaining a better compromise between quality and manufacturing cost.

Recycled fibers from pre- and post-consumer textile waste as blend constituents in manufacturing 100% cotton yarns in ring spinning: A sustainable and eco-friendly approach

“…The manufacturing cost of cotton yarn essentially depends on the price of the raw material and the energy cost ( Wanassi et al., 2018 ). The detailed cost analysis is given in Table 7 .…”

A literature review on circular economy adoption in the manufacturing sector

“…Social implications are rarely included in the evaluation; here some examples are reported. Considering the quality implications affecting products due to CE strategies adoption, Wanassi et al, (2018) analysed and optimized the right trade-off between quality and costs. Indeed, customers' perception, customers' personal income, economic cycles and advent of technology impacts on the instability and uncertainty of product demand.…”
