Dyed fluorescent fabric based on rare-earth-doped MOF and preparation method thereof

Abstract

The invention relates to a dyed fluorescent fabric based on a rare-earth-doped MOF and a preparation method thereof. The dyed fluorescent fabric is obtained by preparing the rare-earth-doped MOF through in-situ polymerization in a normal-pressure aqueous phase in a layer-by-layer self-assembly manner and then assembling the rare-earth-doped MOF with a fluorescent dye. The obtained functional fabric has excellent fluorescence performance, in particular, rarely achieves the fluorescence emission and long fluorescence service life of inexpensive rare earth lanthanum, and also has various functions of bacterial resistance, deodorization, mildew resistance, moth resistance, ultraviolet resistance, flame retardancy and the like. The raw materials of the dyed fluorescent fabric are low in cost and easy to obtain, the process is easy to operate, the production efficiency is high, the energy consumption is low, special equipment is not needed, and the fabric is suitable for industrialized production. The dyed fluorescent fabric based on the rare-earth-doped MOF and the preparation method thereof have the advantages that the development of multifunctional dyed fluorescent fabrics with low cost can be facilitated, and a very good application prospect is also achieved in the fields of special clothing, anti-counterfeiting materials, detection materials, confidentiality materials and the like.

Description

technical field [0001] The invention belongs to the field of fluorescent fabric materials and preparation thereof, in particular to a dyed fluorescent fabric based on rare earth-doped MOF and a preparation method thereof. Background technique [0002] As an important category of textile products, fluorescent fabrics are of great significance for enriching the types of textile products. At present, the commonly used fluorescent fabric products are basically chemical fiber products, such as commonly used polyester, acrylic, nylon, etc., but there are few reports on cotton fabrics with excellent fluorescent effects. In addition, the fluorescent pigments suitable for fabrics on the market today are mainly fluorescent paints, but there are not many fluorescent dyes with excellent fluorescent effects. Fluorescent fabrics printed with pigments often have problems such as color fastness to rubbing and poor hand feeling. The use of fluorescent dyes to dye fabrics can solve this pro...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a dyed fluorescent fabric based on rare earth-doped MOF and its preparation method, which overcomes the lack of fluorescent dyes suitable for fluorescent fabrics in the prior art, the poor fluorescent effect of conventional fluorescent dyes on fabrics and the problem of fluorescent dyes. The dyed fabrics are susceptible to defects such as background fluorescence interference. At the same time, it also solves the problems of poor mechanical properties and mechanical stability between brittle MOFs and flexible fabrics, as well as low luminous efficiency and single luminous mode of flexible fabrics loaded with LnMOF. Rarely realized the application of rare earth lanthanum in the field of MOF light-emitting fabrics; the preparation of pre-finished fabrics in the present invention; the preparation of multifunctional fluorescent fabrics based on lanthanum-doped MOF, and the preparation of multifunctional dyed fluorescent fabrics based on cheap rare earth-doped MOF
