Abstract

The invention discloses a composite noctilucent fiber with a skin-core structure and a preparation method of the composite noctilucent fiber. The composite noctilucent fiber comprises the following components by mass fraction: 50-75wt% of skin layer and 25-50wt% of core layer, wherein the skin layer comprises luminescent material and carrier resin, and the core layer is made from polyolefin resin. The carrier resin of the skin layer is the same as the resin used by the core layer or is different from the resin used by the core layer. The luminescent material in the skin layer is made of light-storage type rare earth long afterglow luminescent powder; the luminescent powder is dispersed into the carrier resin by a mixing pelletizing method, and noctilucent master batch can be formed; noctilucent polyester pre-oriented yarn (POY) is prepared by melting and carrying out skin-core composite spinning on the noctilucent master batch and polyolefin resin; finally, noctilucent fully drawn yarn (FDY) is obtained by a drafting technology. The noctilucent fiber with the skin-core composite structure is high in strength, good in flexibility and high in fiber comprehensive application performance.

Description

technical field [0001] The invention belongs to the technical field of textile fibers, and in particular relates to a composite luminous fiber with a skin-core structure and a manufacturing method thereof. Background technique [0002] Modern society values ​​human life more and more, and the requirements for safety are getting higher and higher, and it has penetrated into all fields of production and life, especially traffic signs and vehicles, which need to work at night or in dark environments, and theaters and dance halls have relatively low light. In dark places, etc., high-visibility products are required to prevent power outages caused by sudden accidents such as earthquakes and fires, resulting in stampede casualties in the dark. Reflective tape is a great product, however, it won't work in the absence of extraneous light. Therefore, there is a need for a product that can emit light, even if there is no external light, it can also play a role in safety warning or gu...
