Abstract
A flexible abrasion resistant water shedding omnidirectionally reflective rope has a central low-density polymeric closed cell foam core comprising EPDM, Neoprene, SBR, NBR, EVA, PVC, PVC/NBR foam surrounded by cylindrically braided sleeve of reflective strips composed of narrow width reflective strips that comprise a woven or knitted narrow width strip and a flexible nylon retroreflective sheet sewn thereon and covered with abrasion resistant water shedding coating. The flexible retroreflective sheet is formed by thermally bonding corner cube, microsphere retroreflectors, or wide angle exposed retroreflective lenses to a flexible polymeric sheet. Due to its low-density foam core construction, the reflective rope floats on water and sheds water from the surface preserving omnidirectional reflectivity. The rope reflects light omnidirectionally over a large angle of acceptance and provides accurate illumination of the rope floating in water, location of a rope wound buoy and the like when used during dusk, fog or nighttime hours.
