Preparation method of long-afterglow red luminescence dacron fabric

Abstract

The invention provides a preparation method of a long-afterglow red luminescence dacron fabric, and relates to the technical field of finishing of textiles. The method comprises the following steps: (1) dissolving phenol in ethyl alcohol; (2) dispersing long-afterglow red luminescence fluorescent powder La2O2S:Eu<3+> into the ethyl alcohol / phenol mixed solution, and ultrasonically treating to obtain the dispersing solution of the fluorescent powder; (3) feeding the dacron fabric into the abovementioned dyeing liquid; oscillating and heating to reach the temperature of 40-60 DEG C, and maintaining the temperature for 5 to 30 minutes; (4) washing with the ethyl alcohol at a plurality of times; then moving out and drying at the temperature of 80 DEG C to obtain the long-afterglow red luminescence dacron fabric. The preparation method is simple in technical processes, and high temperature conditions and complex reaction equipment are eliminated; the prepared long-afterglow red luminescence dacron fabric has the advantages of being nontoxic, high in luminescence brightness, long in afterglow time, and hard to separate; the long-afterglow red luminescence dacron fabric can be widely applied to the fields of clothes, decoration and industry.

Description

technical field [0001] The invention relates to the technical field of textile finishing, in particular to a preparation method of long-lasting red luminescent polyester fabric. Background technique [0002] Polyester is a synthetic fiber with a wide range of uses. With the continuous development of science and technology, more requirements have been put forward for the functional modification of polyester. Among them, long afterglow red luminescent polyester fabric is one of the research contents that many researchers pay attention to. . Long afterglow luminescent fibers can be used in warning clothing, dresses, decorative strips, safety signs and other fields. At present, the luminescent function of long-lasting luminescent fibers comes from inorganic fluorescent materials. The preparation of inorganic luminescent fibers can be mainly divided into two methods: (1) blend spinning method, (2) coating method. The blend spinning method has higher requirements on the particle...

AI Technical Summary

Problems solved by technology

The blend spinning method has higher requirements on the particle size and surface affinity of the phosphor powder, and the processing is more difficult, and the fiber strength is low; the coating method is relatively simple, and is composed of a binder and a phosphor powder. The coating agent is coated on the surface of fibers or fabrics. The disadvantage is that it is easy to peel off, and the adhesive is prone to irritating gas volatilization during use.
