Composite fiber material as well as preparation method and application thereof

Abstract

The invention provides a composite fiber material. The composite fiber material comprises an organic fiber carrier and a plurality of functional nanoparticles embedded into the organic fiber carrier. The invention further provides a preparation method of the composite fiber material. The preparation method comprises the following steps: (1) heating the plurality of functional nanoparticles; (2) jetting the plurality of heated functional nanoparticles onto the organic fiber carrier through hot air flow, and melting contact parts of the organic fiber carrier and the plurality of functional nanoparticles so as to embed the plurality of functional nanoparticles into the organic fiber carrier. The composite fiber material takes the organic fiber carrier as a carrier so as to effectively load the functional nanoparticles. In the loading compounding way, the high loading capacity of the functional nanoparticles can be achieved. Meanwhile, the functional nanoparticles are expanded to all scenes to which a flexible fiber carrier can be applied. The composite fiber material can be applied to the fields of sewage purifying treatment, air purifying treatment or antibacterial sterilizing treatment or the like.

Description

technical field [0001] The invention belongs to the field of fiber materials, in particular to a composite fiber material and its preparation method and application. Background technique [0002] At present, the traditional water pollution treatment methods used in the domestic and foreign markets are physical methods, chemical methods, and biological methods, each of which has its own disadvantages, high cost, high energy consumption, and even secondary pollution, and the purely purified water is still " Dead body", only the ecological system that restores the balance of the water body can make the water environment truly "resurrected". Traditional treatment methods cannot fundamentally solve water quality problems, so even if a lot of manpower, material resources, and financial resources are invested, the effect is still very small. Therefore, breakthrough technologies that can completely solve river water pollution control are urgently needed. [0003] Photocatalytic mat...

AI Technical Summary

Problems solved by technology

Traditional photocatalysts mainly include nanomaterials, such as nano-titanium dioxide; however, the use of these photocatalyst nanomaterials to treat sewage has been limited to laboratory scientific research for many years, because nanoscale materials with high activity are easy to agglomerate and difficult to recycle, so it is necessary to Load it on the carrier for application

However, its loading technology has encountered a bottleneck that is difficult to break through: the use of inorganic carriers reduces its activity, while organic carriers are easily corroded by light during use.
