Abstract

The invention belongs to the field of polymer fibers, and particularly discloses a composite fiber membrane for preventive protection of paper cultural relics and a preparation method of the composite fiber membrane. The composite fiber membrane is characterized in that the composite fiber membrane integrates the functions of ultraviolet shielding, super-hydrophobicity, mechanical supporting and the like, and also has the performances of flexibility, high porosity and high specific surface area of a fiber material. The method is easy and convenient to operate, the paper cultural relics can be effectively prevented from being damaged by ultraviolet rays, dust, pests, bacteria and fungi, and meanwhile it is guaranteed that calligraphies and paintings of paper cannot change.

Description

technical field [0001] The invention relates to the field of polymer fibers, in particular to a preparation method and application of composite fibers that can be used for preventive protection of paper cultural relics. Background technique [0002] As a carrier of history and culture, paper cultural relics are an important part of cultural heritage. They contain a large number of precious cultural historical materials and records, and are also one of the most difficult types of cultural relics to preserve for a long time. Because the main raw materials of paper cultural relics are plant fibers such as cellulose, the oxygen bridges in cellulose that connect glucose into long chains attract H + characteristics and easily oxidized groups in the cellulose structure (-CH 2 OH and -OH) make it prone to a series of chemical reactions, which in turn trigger cellulose chain breaks. Therefore, during the preservation process, paper cultural relics will be easily broken by environme...
