Document Type and Number:
WIPO Patent Application WO/2021/104221
Kind Code:
A1
Abstract:
Disclosed are a flame-retardant, heat-insulating, burn-through-resistant and metal-molten-drop-resistant multifunctional composite fabric and a preparation method therefor. The composite fabric comprises a flame-retardant heat-reflecting outer layer (1), a first heat insulation layer (2), a second insulation layer (3) and a comfort layer (4) in sequence from top to bottom. The flame-retardant heat-reflecting outer layer (1) is formed by compositing a base cloth layer (12) and a functional film layer (11), wherein the functional film layer (11) is a high-temperature-resistant polymer film hybridized with heat-reflecting nanoparticles and the base cloth layer (12) is a blended woven fabric of organic high-temperature-resistant fibers and ordinary flame-retardant fibers, or is an ordinary flame-retardant woven fabric. The first heat insulation layer (2) is a blended woven fabric layer of intrinsic flame-retardant fibers and high heat shrinkage fibers. The second heat insulation layer (3) is a phase-change flame-retardant fabric layer. The comfort layer (4) is a viscose-covering polyester moisture-conducting woven fabric layer. The method for preparing the composite fabric involves first preparing the fabric of each layer, and then quilting same to obtain the whole composite fabric. The present invention has the multiple effects of flame retardance, metal molten drop resistance, burn-through resistance and heat insulation, and can be directly used for preparing protective clothing for high-temperature operations.
