Title:
RADIATIVE COOLING FIBER AND PREPARATION METHOD FOR FABRIC THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/203867
Kind Code:
A1
Abstract:
A radiative cooling fiber and a preparation method for a fabric thereof, the method comprising: mixing inorganic micro-nano particles and a polymer substrate material according to a predetermined weight ratio so as to obtain a composite material masterbatch; and molding by compounding and extruding the composite material masterbatch in a spinning assembly, and obtaining a radiative cooling fiber after winding. In the present invention, high-concentration inorganic micro-nano particles are introduced into a polymer fiber by using a melt composite spinning method, by precisely regulating the size of the micro-nano particles and the internal composite structure of the fiber, the fiber has a high mechanical strength and weaving performance while having an excellent daytime radiative cooling performance, obtaining a radiative cooling fabric suitable for cooling the surface of the human skin; in addition present invention also has the advantages of large-scale mass preparation, low costs, and high production efficiency.
