Title:
FULL-SPECTRUM REFLECTIVE FACE MASK
Document Type and Number:
WIPO Patent Application WO/2023/006032
Kind Code:
A1
Abstract:
A full-spectrum reflective face mask, comprising a face mask body. The face mask body comprises: a full-spectrum reflective layer (1), a filter layer (2) and a skin contact layer (3) which are sequentially arranged in a stacked manner from outside to inside. The full-spectrum reflective layer (1) is formed of a metamaterial spunbond fabric. The metamaterial spunbond fabric comprises at least one single-layer fiber spunbond layer. The single-layer fiber spunbond layer comprises metamaterial fibers (10), and the metamaterial fibers (10) are interwoven and overlapped to form pores, wherein among the pores, the pores having a diameter of 100-3000 nm are reflective pores (30), the total volume of the reflective pores (30) accounts for 10%-90% of the volume of the spunbond fabric. The metamaterial fibers (10) are formed of a composite material including a polymer base material (11) and micro-nano particles (12), with the average particle size of the micro-nano particles (12) being 100-3000 nm. The full-spectrum reflective face mask can guide and manipulate solar radiation and human infrared heat radiation, and can perform photo-thermal regulation and control on the microenvironment temperature between the spunbond fabric and human skin, so as to achieve high-efficiency thermal management.
