Problems solved by technology

[0004] With the development of the national economy and the improvement of people's living standards, the safety of traffic workers and ordinary people walking at night is imminent. Because 3M and most domestic reflective material manufacturers prepare reflective cloth with high cost and slow production speed, raw materials Under the limitation of various factors such as the narrow range of sources, it is necessary to develop a low-cost, fast-production, and new process for making reflective fabrics.

Abstract

The invention relates to the field of manufacturing of reflective fabrics and in particular relates to a method for preparing a high-brightness reflective fabric. The method comprises the following process flows: (1) coating a bead embedding adhesive layer on a PET film, and drying through a drying box, thereby obtaining a bead embedding adhesive layer; (2) placing the bead embedding adhesive layer prepared in the step (1) in a glass bead groove for embedding beads, embedding the glass beads into the bead embedding adhesives for realizing bead embedding through the actions of a composite roller and a compression roller; (3) transferring a semi-finished product subjected to bead embedding in the step (2) into coating equipment, turning metals from a solid state into a gaseous state through a resistance heating mode, and desublimating the metals into a metal coating when meeting a bead embedding film; (4) coating a composite adhesive layer on the surface of a base fabric, drying the solvent, compounding a reflective layer, and compounding through blanching; and (5) stripping to remove the PET film and the bead embedding adhesive layer, thereby obtaining the finished product. The key control of the high-brightness reflective fabric refers to raw material selection and blending of the composite adhesive, namely the composite adhesive layer has the effect of adhering the reflective layer and the base fabric, the washing resistance of the composite reflective layer determines the quality of the washed product, the higher the viscosity of the composite adhesive is, the higher the washing resistance is, and the brightness of the washed high-brightness reflective fabric is higher.

Description

technical field [0001] The invention relates to the field of reflective fabric manufacturing, in particular to a preparation method of high-brightness reflective fabric. Background technique [0002] Reflective fabric is a high-tech product that is widely used in traffic safety equipment, film, protective clothing, work clothes, and uniforms, which are closely related to the safety of human life and property. This kind of reflective fabric is made of high refractive index glass beads retro-reflective principle, through the advanced technology of focusing and post-processing, it can reflect the distant direct light back to the luminous place, no matter it is night or day, it has good retroreflection optical properties. Especially at night, it can exert the same high visibility as during the day. Its appearance has successfully solved the night driving problem of "being seen" and "seeing". Or scattered light interference, or in the case of remote places, can be easily spotte...
