Problems solved by technology

[0010] The Chinese patent literature publication number is CN1281012A, which reports a manufacturing method of a retroreflective coating and its coating. The glass microspheres used have a refractive index N of about 1.9, which is a retrocoat produced by the transfer process. product, its retroreflection coefficient is only 100-180cd / LX / m 2 , cannot meet the high brightness requirements of current reflective fabrics
The product reported in this patent is a non-exposed product, and it is a product with a large number of layers. Its preparation process is relatively complicated, which also affects the performance of the product.

Embodiment 1

[0043] The retro-reflective fabric of this embodiment sequentially includes a textile base fabric layer, an opaque specular reflection layer, a polymer adhesive layer, and an optical lens element layer. The amount of glass microbeads contained in the optical lens element layer is the retro-reflection per square meter. The fabric contains 110 grams of glass microbeads. The textile as the base fabric layer is pure cotton cloth. After pretreatment, the coating thickness of the opaque specular reflection layer is 0.2mm, and the glass microbeads in the optical lens element layer have a refractive index of 1.90 and an average diameter of 1.90. 40 micron glass microbeads, 60% of the diameter of the glass microbeads are exposed on the surface of the polymer adhesive layer, and then the retro-reflective fabric treated with a waterproofing agent.

[0044] The preparation method is as follows: the used textile base cloth layer is pure cotton cloth, and the pure cotton cloth used as the ba...

Embodiment 2

[0051] The structure and preparation method of the retro-reflective fabric in this example are basically the same as those in Example 1, except that the amount of glass microbeads used in the optical lens element layer is 90 grams of glass microbeads per square meter of the retro-reflective fabric. . The coating thickness of the opaque specular reflection layer is 0.1 mm, and the glass microbeads in the optical lens element layer are glass microbeads with a refractive index of 1.93 and an average diameter of 30 microns. 50% of the diameter of the glass bead is exposed on the surface of the polymer adhesive layer.

[0052] The used textile base fabric layer is polyester-cotton fabric, which is prepared with water and methyl acrylate into an aqueous emulsion containing 30% by weight of methyl acrylate and impregnated the polyester-cotton fabric as the base fabric layer, and then the excess slurry is rolled out.

[0053] In the aqueous emulsion containing 20% ​​by weight of meth...

Embodiment 3

[0058]The structure and preparation method of the retro-reflective fabric in this example are basically the same as those in Example 1, except that the amount of glass microbeads used in the optical lens element layer is 130 grams of glass microbeads per square meter of the retro-reflective fabric. beads. The coating thickness of the opaque specular reflection layer was 0.25 mm, and the glass beads used in the optical lens element layer were glass beads with a refractive index of 1.91 and an average diameter of 75 microns. 70% of the diameter of the glass bead is exposed on the surface of the polymer adhesive layer.

[0059] The base fabric layer of the textile used is polyester spun fabric, and the water emulsion prepared with water and propyl acrylate containing 55% by weight of propyl acrylate is impregnated as the base fabric layer polyester spun fabric, and then the excess slurry is rolled out.

[0060] A specular reflection layer slurry coating solution was prepared by ...

Abstract

The present invention relates to product with special surface layer and its making process. The product includes successively basic fabric layer, opaque mirror reflecting layer, polymer adhesive layer, and optical lens element layer containing glass bead in the amount of 90-130 g / sq m. The making process includes first forming opaque mirror reflecting layer on the basic fabric layer, and then then forming the optical lens element layer. The present invention may be used in makes suits for night worker to reduce accident.

Description

technical field [0001] The invention relates to a layered product with a special surface and a production process thereof, in particular to a retroreflective layered fabric with a base fabric layer, a reflection layer, an adhesive layer and an optical lens element layer and a preparation process thereof. Background technique [0002] The retro-reflective fabric has the special function of reflecting the incident light back to the light source in the direction of the incident light, which is very eye-catching when there is a light source at night. People who travel at night, such as traffic police, sanitation workers, underground miners, railways and other departments, wear work clothes with retro-reflective fabrics, which have a safety protection effect and avoid accidents. Therefore, retro-reflective fabrics are widely used in the tooling or ordinary civilian clothing of personnel working at night or in the dark. The observer can find the target from a distance and take tim...
