A super-black high-brightness reflective fabric and its manufacturing method

Abstract

The present invention discloses a super-black high-brightness reflective fabric and a manufacturing method thereof. A super-black high-brightness reflective fabric includes a fabric layer, a composite adhesive layer, a reflective layer, a black bead-planting adhesive layer, glass beads, and a black surface layer. A black dye with high solubility is added to the black bead-planting adhesive layer, and a highly transparent black surface layer containing a black ink with high solubility is added on the surface and between the gaps of the glass beads. On the premise of ensuring that the product has a high-brightness reflective effect, the black saturation on the surface of the product is greatly increased. The composite adhesive layer uses polyurethane resin or polyacrylic resin, which has high temperature resistance and water-wash resistance, and has extremely high bonding strength with the glass beads and the reflective layer, greatly ensuring that the brightness attenuation of a super-black high-brightness reflective fabric is reduced during the water-washing process. The reflective layer is an aluminum metal dielectric layer or a silver metal dielectric layer, greatly ensuring the reflection performance of the product.

Description

Technical Field

[0001] The present invention relates to the technical field of reflective fabrics, and particularly to an ultra-black and high-brightness reflective fabric and a manufacturing method thereof. Background Art

[0002] Due to special properties such as retro-reflection and no need to provide its own energy, reflective materials are widely used in fields such as highways, aerospace, navigation, night operations, and clothing decoration. The manufacture of reflective fabrics involves the manufacture and compounding processes of various materials. These materials include optical reflection elements, a bottom layer, a surface layer, an adhesive layer, and other auxiliary layers. With social progress, people's demand for new clothing is increasing day by day, and special requirements are put forward for new clothing material processing technologies. With the continuous improvement of safety and aesthetic awareness, the reflective materials used in clothing have changed from the previous gray or silver-gray to colors.

[0003] For the existing colored reflective fabrics on the market, due to the low reflective brightness or the lack of fullness of the surface color, especially for black reflective fabrics, the product has a low reflective brightness or the surface color turns gray after the reflective brightness is increased and fails to achieve the black effect, resulting in limitations in the special applications of some special clothing industries and no longer meeting the requirements of some high-end customers and the development of the corresponding clothing industries. Therefore, it is necessary to improve this situation. Summary of the Invention
