Research progress in development and application of Calotropis gigantea fiber

Calotropis gigantea fiber(CGF)is to a type of seed fiber collected from the fruits of the Calotropis gigantea(CG).From a sustainable biomass resource,CGF is a naturally abundant cellulose fiber with good economic value,excellent biocompatibility and biodegradability.CGF has a high hollow structure and is lightweight,which means CGF has received increasing attention in recent years as the starting material for fabrication of different types of functional materials.In this paper,we have reviewed the morphology and characteristics of CGF,including its biological properties,chemical composition,and physical properties.Additionally,we provide an overview of the recent advancements in the extraction process,toughening treatment process,spinning process,and weaving process of CGF,which have garnered significant attention from researchers in the field.The applications of CGF in the fields of environment processing,antibacterial,and smart materials are also summarized.Finally,the challenges and development prospects of CGF are introduced with the ultimate goal of implementing its potential in real-world applications.
