Abstract
A thread-like continuous retroreflective fiber and method of making same, comprising the steps of laminating a thin film of retroreflective material to a supporting polyester film, and then slitting the laminate to form narrow strips of retroreflective material having sufficient strength to be combined with other fibers to form a composite yarn having retroreflective characteristics, which composite yarn may then be woven, knitted, or spun to provide a fabric having retroreflective characteristics.
Claims5
A method of making a thread-like continuous fiber having retroreflective characteristics and having sufficient structural strength to permit it to be effectively used during knitting, weaving or spinning of a composite yarn or fabric consisting of the following steps:
- (A) Providing a thin film of retroreflective material consisting of a plurality of exposed minute glass beads bonded in a flexible elastomeric material;
- (B) Laminating thereto a thin flexible supporting film so as to provide a laminate defined by said retroreflective material on one surface and said supporting film on the opposite surface;
- and
- (C) Slitting said laminate into elongated thread-like fibers.
