The patent application describes an innovative article of apparel featuring a dynamic vent structure. The vent is created by overlapping edges of two panels, with a unique mechanism that allows it to open or close in response to external stimuli, such as moisture. This is achieved through the integration of discrete overlay film structures on one of the panels, which expand in size when exposed to such stimuli, thereby causing the vent to transition from a closed to an open state.
The apparel utilizes advanced material technology, specifically responsive overlay film structures, to facilitate the dynamic opening and closing of vents. This approach contrasts with traditional methods that rely on mechanical components like zippers or passive air flow mechanisms. The innovation offers a more adaptable and potentially more comfortable solution for temperature and moisture regulation in clothing.
The apparel consists of two main panels, with discrete overlay film structures applied to the second panel near the vent opening. These films are designed to expand in the z-direction when exposed to moisture. This expansion causes a reduction in the panel's dimension along the vent's longitudinal axis, effectively opening the vent. The design ensures that these film structures are oriented perpendicularly to the vent's axis for optimal functionality.
The overlay film structures are made from thermoplastic polyester elastomer and have a thickness ranging from about 30 microns to 50 microns. They can be affixed either on the inner or outer surface of the second panel but are not attached to the first panel. This strategic placement allows the second panel alone to react dynamically, ensuring efficient operation without affecting the first panel's integrity.
This technology can be applied to both upper-body and lower-body garments, offering versatile applications across various types of apparel. Additionally, the method of manufacturing emphasizes discontinuous affixing of panels and precise placement of film structures to achieve desired vent dynamics. The system can also be integrated into textiles with slits or apertures for enhanced breathability and comfort.
