Abstract

The invention discloses a superfine electroluminescent fiber and a preparation method and application thereof, and belongs to the technical field of textile chemical fibers. A high-conductivity core layer fiber electrode is used as a carrier, a luminescent material is used as an active layer, and a controllable coating process is used for compounding. The electroluminescent fiber with high luminance, long service life and various colors can be finally obtained by regulating and controlling the ratio of the luminescent slurry and dip-coating process parameters. The diameter of the prepared luminescent fiber is 0.15-0.5 mm, the brightness is adjustable in a range of 20-200cd / m < 2 >, and the color is diversified. The preparation method is simple in preparation process, mild in condition, green, environment-friendly, low in cost and suitable for industrial production. The prepared luminescent fiber is controllable in size, high in brightness, diversified in color, good in flexibility, easy to weave and wide in application. The luminous fiber can be subjected to plain weaving, weaving, sewing, embroidery, knitting and the like by using industrial textile equipment, and the fabric and patterning of the luminous fiber have a function indication effect and an attractive effect.

Description

technical field [0001] The invention belongs to the technical field of textile chemical fibers, and relates to an ultrafine electroluminescent fiber, a preparation method and application thereof. Background technique [0002] In recent years, the application of luminescent materials (mainly luminescent fibers and luminescent fabrics) in clothing has received widespread attention. Clothing containing luminescent materials plays an important role in transportation, fire protection, costume design, stage performances and other fields. Luminescent fiber and fluorescent fiber are more in the market at present. It mainly absorbs energy through light, and then converts it into light radiation. Generally, polyester, nylon or polypropylene is used as the base material, and rare earth long-lasting luminescent materials and nano-scale functional additives are added. The light conversion function made by special spinning technology fiber. The fiber has various colors when there is vis...
