Problems solved by technology

But these two methods have certain disadvantages. The blue light needs to be irradiated continuously for 12-24 hours. During the irradiation period, due to the baby’s restlessness, the baby’s eyes and perineum coverings may fall off, thereby damaging the baby’s vision and physical health; drug treatment In the case of jaundice, due to the incomplete development of the newborn's body resistance and metabolic ability, the baby itself cannot completely metabolize the drug, resulting in drug residues and damaging the baby's health
[0004] To sum up, under the current medical level, there are certain disadvantages and inconveniences in the method for treating infantile jaundice, and there are certain disadvantages and inconvenient places for the treatment of jaundice. The cure is what is missing in the current situation

Abstract

The invention discloses a blue-green double-color self-luminous fiber and a preparation method thereof, the blue-green double-color self-luminous fiber comprises a skin layer and a core layer, the skin layer comprises chinlon and a rare earth magnesium strontium silicate long-afterglow luminescent material, and the core layer comprises polyester and a rare earth strontium aluminate luminescent material. The blue-green double-color self-luminous fiber provided by the invention has good luminous performance and also has the advantages of high efficiency, energy conservation, no pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of fiber filament preparation, and particularly relates to a blue-green two-color self-luminous fiber and a preparation method thereof. Background technique [0002] In today's society, under the influence of the living environment and living habits of pregnant women, about 60% of full-term infants and 80% of premature infants will develop jaundice, which is due to excessive bilirubin production and the low ability of the newborn's liver to metabolize bilirubin. It is caused by the phenomenon of normal development process, and often does not require special treatment. Early opening of milk and promotion of defecation are beneficial to promote bilirubin metabolism. However, in severe cases, jaundice can cause bilirubin encephalopathy, which will bring about damage to the nervous system and audio-visual, reduce the ability to exercise and learn, and reduce the quality of life in the future. Moreover, some jaun...
