Problems solved by technology

However, the fluorescent cloth prepared by this method is easy to drop the fluorescent particles during the washing process, and the fluorescent effect is not obvious at the same time, so it cannot play a good warning effect
[0003] Coating fluorescent dyes on the surface of the fabric is another way of preparing fluorescent fabrics. The fluorescent particles are fixed on the surface of the fabric through an adhesive. However, during the coating process, uneven application of fluorescent particles is prone to occur, which is unsightly. fluorescent effect

Abstract

The inventor provides a fluorescent fabric and a preparation method thereof, including the following steps: making a bottom layer, making a black ink layer, making a bright surface gold oil layer, making a fluorescent inner layer, and making a fluorescent outer layer. The fluorescent fabric prepared by the technical solution has a higher content of fluorescent particles per unit volume in the edge portion of the fluorescent inner layer, and the edge of the fluorescent inner layer has better fluorescent effect. Since the concentration of water-based polyurethane in the fluorescent outer layer is higher than that of the fluorescent inner layer, the entire fluorescent outer layer and the fluorescent inner layer have different refractive indices of light, and the light has more refraction angles, which also makes the fluorescent particles better.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a fluorescent cloth and a preparation method thereof. Background technique [0002] At present, fluorescent dyes are generally added in the dyeing process of the fluorescent fabrics on the market, so that the dyes penetrate into the fabrics. However, the fluorescent fabric prepared by this method is easy to fall off during the washing process, and the fluorescent effect is not obvious, so it cannot play a good warning effect. [0003] Coating fluorescent dyes on the surface of fabrics is another preparation method of fluorescent fabrics. The fluorescent particles are fixed on the surface of the fabrics through adhesives. However, during the coating process, the uneven application of fluorescent particles is prone to occur, which is not aesthetically pleasing. Fluorescent effect. SUMMARY OF THE INVENTION [0004] In order to solve the above problems, the inventor provides a fluorescent...
