RESPIRATOR HAVING ELASTIC STRAPS HAVING OPENWORK STRUCTURE
摘要
Various embodiments of a respirator are disclosed. The respirator can include a mask body and one or more elastic straps that are secured to the mask body on opposing sides. The elastic straps can have an openwork construction and can include a netting that has an array of polymeric strands periodically joined together at bond regions throughout the array. In one or more embodiments, the openwork elastic straps are lighter and more breathable than conventional straps. This improvement in breathability can make the respirator more comfortable to wear.
