MEHRSCHICHTIGE MIKROFASERN UND DARAUS HERGESTELLTE ELASTISCHE VLIESSTOFFE

摘要

A retroreflective sheet comprising a monolayer of retroreflective elements partially embedded in and partially protruding from the front surface of a binder layer and a backing bonded to the back surface of the binder layer wherein the backing is elastic and comprises a highly conformable and deformable nonwoven web comprising melt-blown microfibers having multiple layers of a relatively low modulus material and a high modulus material.
