STRUCTURE COMPOSITE DE TYPE DUVET

Abstract

------ DOWN-TYPE COMPOSITE STRUCTURE The invention relates to a down-type composite structure (1), comprising a base layer (10) and a down-type layer (11) disposed thereon; the base layer (10) and the down-type layer (11) individually comprise a core-sheath fiber (20), a microfiber (21) and a 3D looped fiber (22); the base layer (10) being prepared by cross-stacking the above fibers and has a density of 14 g / m² to 40 g / m²; the down-type layer (11) is prepared by random stacking of the above fibers and has a density of 30 g / m² to 400 g / m²; the microfiber (21) has a fineness of 0.1 D to 1.5 D, measured according to the ISO 1973 standard method; The 3D looped fiber (22) has a hollowness rate of 5% to 30%, measured according to the standard method GB / T 38902-2020 and a curl rate of 2% to 25%, measured according to the standard method ASTM D3937.The down-like composite structure (1) has a compression recovery rate of 90% or greater, measured according to the ASTM D6571-01 standard method. The invention also relates to articles and garments prepared with the down-like composite structure (1). Figure to be published with the abstract: Figure 1.
