| dc.description.abstract | This 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. | |
