Abstract: A retroreflective piping sheet for vehicle interior decoration includes a fabric layer having a fabric circular-knitted from a ply yarn of polyester and spandex, a retroreflective layer, disposed on a one side of the fabric layer, having a plurality of glass beads therein and a hot melt adhesive layer disposed on the other side side, opposite to the one side, of the fabric layer.

Abstract: A retroreflective sheet and a fabrication method thereof are provided, the retroreflective sheet including a base, a bonding layer formed on the base, a colored layer formed to be thicker in a non-reflective region NRA2 than in a reflective region RA2 to have a concavo-convex surface on the bonding layer, and having a fluorescent function or a phosphorescent function or having the both fluorescent and phosphorescent functions, a reflective layer formed in the concave portion of the reflective region RA2 on the surface of the colored layer, and a light concentrating layer having a plurality of beads aligned therein on the reflective layer. Thus, since a step is not generated between the reflective region and the non-reflective region, the light reflective member can be prevented from being delaminated from the body when used, and also, the light reflective member can be simply formed in the reflective region of the colored layer.
