- ItemRESEARCH ON INFLUENCE OF SEALING PARAMETERS ON STRENGTH AND WATER RESISTANCE OF STITCH-SEALING AND WELD-SEALING SEAM(2025) NGUYEN, QUOC TOAN; DAO, THI TINH; TRAN, THI NGAT; PHAN, DUY-NAMThis study presents a comparative investigation of the performance of two-seam sealing techniques stitchsealing and ultrasonic weld-sealing applied to three-layer waterproof fabric composites used in highperformance apparel. A Box-Wilson Central Composite Design was adopted to systematically evaluate the effects of three critical sealing parameters temperature, sealing speed, and air pressure on seam thickness, tensile strength, and hydrostatic water resistance. Experimental trials were conducted both before and after 10 standardized domestic laundering cycles, following ISO 811 (hydrostatic head test) and ISO 13935-2 (grab tensile strength) protocols. Results revealed that weld-sealed joints consistently exhibited lower seam thickness and superior water resistance under all tested conditions, contributing to enhanced wearer comfort. Conversely, stitch-sealed seams demonstrated significantly higher tensile strength, particularly under high-temperature and high-pressure settings. Quadratic regression modeling indicated that temperature was the most influential parameter, with notable two-factor interaction effects observed especially between temperature and air pressure. These findings underscore the importance of optimizing sealing conditions based on end-use requirements, offering a scientific basis for the rational selection of seam sealing technologies in the manufacturing of functional waterproof garments.
- ItemTRENDS AND GAPS IN SUSTAINABLE FASHION RESEARCH: A BIBLIOMETRIC ANALYSIS(Technická univerzita v Liberci, ) DIVRIK, ASLI SEDEFThis research consists of a bibliometric analysis on sustainable and fast fashion that were published between 2007 and March 2025. With 764 articles taken from the Web of Science the analysis contains co-citation, co-occurrence, and clustering techniques to map thematic trends. There is an intense growth in research after 2015 and even further intensification post-2020 in alignment with the rising consumer awareness and policy initiatives. The results demonstrate that sustainability is an interdisciplinary field spanning environmental sciences, business, consumer studies, and textile engineering. Fiber recycling, bio-based fabrics, and low-impact dyeing are emerging themes, while gaps remain in communication, ethics, and cultural dimensions.
- ItemADAPTIVE CLOTHING DESIGN: FROM FOCUS GROUP EVALUATION TO FUNCTIONAL PROTOTYPES(Technická univerzita v Liberci, 2025) BUKHANTSOVA, LIUDMYLA; LUSCHEVSKA, OLENA; KOVALCHUK, DMYTRO; ZAKHARKEVICH, OKSANA; KRASNIUK, LARYSA; DITKOVSKA, OLESYA; YANTSALOVSKYI, OLEKSANDR; KULESHOVA, SVITLANA; SHVETS, GALINAThe importance of adaptive clothing has grown considerably in response to the needs of individuals with physical disabilities, whether congenital or acquired. This study explores the principles of user-centred design in developing adaptive clothing, using a framework informed by focus group discussions. The aim was to gather detailed insights to guide the design process, ensuring that users' needs and preferences are effectively addressed. To achieve this, three separate focus groups were created, comprising 7 medical staff, 5 patients from the surgical department, and 12 patients undergoing rehabilitation. This diverse representation sought to address the different needs associated with varying mobility levels, treatment durations, and care requirements. The approach aims to understand the experiences and needs of adaptive clothing users thoroughly. As a result, an effective adaptive design was developed, focusing on clothing that is not only functional and visually appealing but also genuinely meets the users' needs.
