SELECTING USED SCHOOL UNIFORM SHIRTS FOR REUSE BY QUANTITATIVE METHOD

Tóm tắt

This study was conducted to evaluate the remaining quality and the reuse potential of used school uniforms. If any sample shirt meets this requirement, the group of shirts represented by this sample will be selected for reuse. The remaining quality of the used shirt is evaluated based on its appearance quality and physical durability. In which, the appearance quality is quantified according to the criteria: pilling and colorfastness of the shirt fabric. The physical durability is quantified according to the criteria: tensile strength, tear strength and seam strength of the shirt fabric. The individual evaluation criteria are determined according to industry standards. The results of the study of 5 used uniform shirts of School A show that the remaining quality of the shirts and the individual quality in each evaluation criterion all meet the requirements of the user of the used shirt. Therefore, all shirts in the group represented by these 5 sample shirts are selected for reuse.
