Abstract

The invention discloses metamaterial spunbond cloth and a preparation method thereof. The metamaterial spunbond cloth comprises at least one single-layer fiber spunbond layer; the single-layer fiber spunbond layer comprises metamaterial fibers; the metamaterial fibers are interwoven and overlapped to form pores; in the pores, the pores with the diameter being 100-3000 nm are reflection pores, and the total volume of the reflection pores accounts for 10%-90% of the volume of the spunbond cloth; the metamaterial fibers are formed by a composite material comprising a polymer substrate material and micro-nano particles; and the average particle size of the micro-nano particles is 100-3000 nm. The metamaterial fibers are arranged in an interwoven mode and the micro-nano particles in the fibers are arranged randomly, the spunbond cloth with the metamaterial characteristics is formed, ultra-wideband optical responses of 0.3-2.5 micrometers and 8-13 micrometers are generated based on the photonic design, then solar radiation and human infrared heat radiation are guided and controlled, and photo-thermal regulation and control are carried out on the microenvironment temperature of the cloth and the human skin to realize efficient thermal management.

Description

technical field

[0001] The present application relates to the technical field of material manufacturing, in particular to a supermaterial spunbonded fabric and a preparation method thereof. Background technique

[0002] With the development of science and technology and the improvement of living standards, people's requirements for textiles tend to be diversified, so various functional materials are applied. Among them, functional materials have attracted more and more people's attention and love because they can improve the comfort of the human body.

[0003] Due to outdoor activities and operations, people are often exposed to harmful sunlight, which can cause skin burns, high temperature heatstroke and other health diseases. Therefore, more and more protective products are used for outdoor protection. Many current protective products are usually multi-layer film structures, including reflective layers made of materials with high reflectivity in the solar spectrum range ...
