Abstract

The invention discloses a self-luminous polypropylene wool top and a preparation method thereof. The preparation method comprises the following steps: S1, grinding a strontium aluminate raw material by a grinder to obtain self-luminous powder, stirring and mixing the self-luminous powder, powdery polypropylene, a thermal dispersant, a calcium-zinc composite thermal stabilizer and polyethylene waxin a stirrer, and performing granulating by a granulator to obtain self-luminous master batches, S2, mixing the self-luminous master batches with polypropylene, melting and spinning the mixed materials, and performing cooling, oiling, drawing, curling and drying to obtain a finished product. The self-luminous polypropylene wool top prepared with the preparation method can emit light for a long time in a dark environment after receiving light for a short time, so that the polypropylene wool top has a self-luminous function, and the application range of the polypropylene wool top is greatly widened.

Description

technical field [0001] The invention relates to the technical field of fiber production, in particular to a self-luminous polypropylene top and a preparation method thereof. Background technique [0002] With the improvement of living standards, functional textiles have rapidly developed into an important part of the textile industry. In addition to conventional performance, special functionality is often required. The existing polypropylene tops do not have luminous function. If polypropylene The ability of wool tops to emit fluorescence will greatly expand the application range of polypropylene wool tops; fluorescent materials can fluoresce in dark environments after being irradiated by ultraviolet or visible light, so fluorescent materials can be incorporated into polypropylene wool tops, due to the addition of fluorescence Materials, the existing preparation method of polypropylene tops cannot meet the requirements for preparing self-luminous polypropylene tops. Conten...
