| 摘要 |
A method is disclosed for producing a printed retroreflective textile material, comprising the following steps : partially embedding, in a self-adhesive or thermo-adhesive supported by a carrier sheet (9) made of paper or polymer foil, a monolayer of transparent glass microspheres (1) at a depth averaging between 20% and 50% percent of the diameters of the microspheres (1); (b) laying an aluminum film (2) onto the microspheres (11) by vacuum deposition; (c) coating a two-component transparent polyurethane adhesive layer (11) onto the microspheres (11) and drying the adhesive layer (11); (d) while the polyurethane adhesive layer (11) is partially cured, applying a base textile material (8) with a design (5) printed thereon; and (e) stripping away the support foil (9) of the microspheres (1) pulling off the aluminum surface between the micro-glass beads (1) and curing the textile material (8) covered with the printed microspheres (1). <IMAGE>
