| Abstract [eng] |
Modern labels based on QR code could be an attractive solution to provide information about garment origin, composition, repair, maintenance and disassembly through the whole product life cycle, reduce waste and promote sustainable resource use. QR code is cost-effective, easy to implement technology, however it also comes with some limitations. The challenges of label quality related to the durability and readability of the integrated QR code in the fabric may appear over time when the label is subjected to mechanical impacts. Earlier research aimed to evaluate the influence of different technologies (embroidery, sublimation, and heat transfer printing) on the quality and readability of QR code. It has proved that embroidery presents the biggest technical difficulties, but this technology has less limitations for fabric composition, heat sensitivity, etc. while compared with other used technologies. Additionally, embroidery conveys a sense of craftmanship, luxury and can also be as part of products design. This study focusses on changes in the geometrical parameters of the embroidered QR code during tensile tests, considering deformations in both the wales and courses directions of the interlock jersey fabric. The geometric distortion of the QR code is estimated based on image analysis. The readability of QR code depends mostly on the finder, timing and alignment patterns that are created within QR code. Previous study revealed that unmatching value percentage is reliable parameter to evaluate the readability of QR code and analyse geometric distortion of QR image elements. The chosen research and assessment approach may have wider applications, potentially extending to other small embroidered features beyond QR codes. |
