Abstract

The invention relates to a preparation method of a yellow luminous fiber, which is characterized in that it comprises the following process steps: (1) mixing a coupling agent, anhydrous ethanol, a light conversion agent that emits yellow light and a silicate fluorescent material, and using ultrasonic dispersion Mix it fully with mechanical stirring, stir it at a certain temperature at a high speed to make it react, dry the absolute ethanol after a certain period of time, and pulverize the sample to obtain a yellow fluorescent material; (2) dry the PA6 slices and combine them with yellow fluorescent The material compound is premixed to obtain the luminous masterbatch material; (3) PA6 slices are uniformly mixed with the luminous masterbatch, melt-spun after drying, and the yellow luminous fiber is obtained after oiling, winding and stretching. The invention prepares the yellow luminous fiber with good mechanical properties, high color purity and excellent afterglow brightness.

Description

technical field [0001] The invention relates to a preparation method of a yellow luminous fiber, belonging to the technical field of functional textile materials. Background technique [0002] With the development of science and technology and the improvement of people's living standards, traditional textile products can no longer meet the needs of people's life and production, and a variety of functional textiles have emerged. Rare earth luminous fiber is a kind of functional fiber, which can store light. It can release light energy in the dark, which can not only meet the needs of night work, but also serve as a sign reminder. At present, there are many kinds of luminous fiber products on the market, which are mainly used in the fields of security, decorative clothing, and anti-counterfeiting. Rare earth luminous fiber is also called fluorescent fiber. Rare earth luminous fiber is mainly composed of fiber-forming polymer and rare earth luminescent material. The fiber-formi...
