Evaluation of Air Textured Warp Yarn Samples with TOPSIS method According to Quality Standards

Umutgül Kaplan, Eren Özceylan



The air textured warp yarn; produced from polyester fiber, is used as warp yarn in carpet weaving industry and is one of the yarns that form the floor of the carpet. Air textured warp yarn; that does not reflect the quality values, will cause elongation, shortening, stretching, shrinkage, irregularity problems in the carpet, during or after weaving process. Since these defects occur on the warp yarn, that forms the length of the carpet, directly affect the quality of carpet to be produced, therefore the purpose of the production in the companies producing this yarn, is based on the philosophy of producing quality products, before making a profit. For these reasons; certain criteria, determining the quality yarn, were identified during the production of air textured warp yarn, and standard production values were assigned, depending on those values. In this paper 649 samples of 800 Denier air-jet textured yarn subjected to a series of strength tests with the physical properties of the yarn. Tested yarn properties are count, elongation, shrinkage, tenacity, RKM (reisskilometer), force in kilograms. All tested properties of the yarns are ranked by TOPSIS method, which is a multi-criteria decision-making method, based on certain weights. As a result all samples, from best to worst, shown to the decision-maker, to try to help which sample will be used in the next step of if a classification will be defined for quality.
