摘　　要：Disposable hygiene products have evolved into the important parts for millions of people around the world,enhancing the convenience of daily lives.However,development of the disposable hygiene products is restricted by unsustainable production technology,complicated operation process,and poor liquid absorption performance of the absorbent core.Herein,integrated and three-dimensional(3D)multifunctional superabsorbent nonwovens with liquid-triggered fragrance release was prepared via green,fast and scalable multi efect hot-air anchoring method which physically crosslinking the joint thermobonding fbers and anchoring fragrance microcapsules/super absorbent polymer(SAP)onto adjacent thermo-bonding fbers simultaneously.The resulting composite nonwovens could three-dimensionally absorb water 33.14 times of its own weight without gel blockage between SAP,and correspondingly release increased intensity fragrance along with enhancing amount of water absorption.Absorption rate t1 and t2 is 83.62%and 50.62%higher than the commercial specimen respectively,and the air permeability is increased by 226.88%compared with the commercial specimen.The superabsorbent nonwovens with controllable fragrance release and odorant synergistic has the potential to be practically applied to functional textiles felds because of the excellent liquid absorption and controlled fragrance release performance,and is easy to be produced on a sustainable,pollution-free and large-scale industrial production.
