Abstract

The invention relates to a superfine polyester fluorescent fiber with a high adsorption function and a preparation method thereof, in particular to a superfine polyester fluorescent fiber with the high adsorption function based on sulfonic acid functionalized polystyrene microspheres and a preparation method of the superfine polyester fluorescent fiber with the high adsorption function. The preparation method comprises the steps of blending with polyester by using polyester master batches of mixed and blended sulfonic acid group modified polystyrene microspheres when the polyester fiber is prepared, and carrying out melt spinning to obtain the polyester fiber in the shape of a Chinese character 'mi' (the part in the shape of the Chinese Character 'mi' is polyester nylon, and the rest partis polyester blended with microspheres) which radially penetrates through the cross section. The specific surface area of the fiber is large, and the sulfonic acid functionalized polystyrene fluorescent microspheres are uniformly dispersed in a polyester matrix, so that the fiber is carried with sulfonic acid groups. The difficulty of low loading rate of sodium sulfonate in polyester in the priorart is overcome, the microspheres with high loading rate are mixed and doped into the polyester, the loading rate of the polyester sodium sulfonate is improved, and the superfine fiber has a large specific surface area, so that the obtained polyester fiber has high adsorption energy.

Description

technical field [0001] The invention belongs to the technical field of fiber preparation, and relates to a superfine polyester fluorescent fiber with high adsorption function based on sulfonic acid functionalized polystyrene microspheres and its preparation method Background technique [0002] Heavy metals are indispensable "micronutrients" for human health. They widely exist in human muscles and bones, and play a very important role in human life activities and metabolism. But when the content of these heavy metals is high, it will have a toxic effect on the human body. In recent years, due to the continuous progress of society and the continuous development of industry, the excessive content of heavy metals in sewage, sludge and soil has caused potential harm to the environment. After these heavy metals invade the human body, they do not have the same effect on various organs, but have direct toxic effects on some organs. [0003] At present, the methods for removing hea...
