20.500.12556/RUL-164738 Optimization of knitted fabrics for better thermo-physiological comfort by using Taguchi-based principal component analysis Optimizacija toplotnega udobja pletiv z analizo glavnih komponent, temelječo na Taguchijevi metodi The water, air permeability and thermal resistance of fabrics are important attributes that have a significant impact on the thermal comfort properties of sportswear fabrics in different environmental conditions. In this work, terry and fleece fabrics were developed by varying the fibre content and mass per unit area of fabrics. Moreover, the thermo-physical properties of the developed fabrics, including air permeability, water vapor permeability and thermal resistance, were analysed before and after washing. The multi-response optimization of the thermal comfort properties of knitted fabrics was performed using principal component analysis (PCA) and the Taguchi signal-to-noise ratio (PCA-S/N ratio) to achieve optimal properties. It was determined that the selected parameters (fabric type, finishing, fibre content and fabric mass per unit area) had a significant effect on the thermal comfort properties of knitted fabrics. The PCA analysis showed that 100% cotton terry fabric before washing with an aerial weight of 220 g/m$^2$ had higher air and water vapor permeability value, but a lower thermal resistance value. Prepustnost za vodo, zračna prepustnost in toplotni upor pletiv pomembno vplivajo na toplotno udobje športnih oblačil v različnih okoljskih razmerah. V tej raziskavi so bila izdelana frotirna in flisna pletiva s spreminjanjem razmerja bombaža in poliestrskih vlaken ter spreminjanjem ploščinske mase. Pred pranjem in po njem so bile pletivom analizirane zračna prepustnost, prepustnost vodne pare in toplotni upor. Večodzivna optimizacija lastnosti toplotnega udobja pletiv je bila izvedena s pomočjo analize glavnih komponent (AGK) in Taguchijevega razmerja signal/šum (razmerje AGK-S/N) za optimalne lastnosti. Ugotovljeno je bilo, da so izbrani parametri (vrsta pletiva, plemenitenje, vsebnost vlaken in ploščinska masa pletiva) pomembno vplivali na lastnosti toplotnega udobja pletiv. Analiza glavnih komponent je pokazala, da je neoprano 100-odstotno bombažno frotirno pletivo s ploščinsko maso 220 g/m$^2$ doseglo najvišje vrednosti zračne prepustnosti in prepustnosti vodne pare in najnižji toplotni upor. fibre blends fabric construction heat and transmission properties of fabric statistical analysis mešanice vlaken konstrukcija pletiva toplota prepustnost statistična analiza true false true Angleški jezik Slovenski jezik Članek v reviji 2024-11-08 11:06:51 2024-11-08 11:06:52 2026-01-21 12:12:01 0000-00-00 00:00:00 2023 0 0 V datoteki članka je naveden napačen DOI: 10.14502/tekstilec.66.2022024.
