Advances in the Study of Structures,Extraction Methods and Characterization of Natural Plant Dyes
Dyeing and finishing process is the key part to give high added value to textiles,which is developing towards the direction of green,environment-friendly and sustainable.Due to the advantages of environmental friendliness,biodegradability,and functionalization of some dyed fabrics,the natural plant dyes have set off a new research boom.Starting from the classification and chemical structure of natural plant dyes for textile dyeing,this paper focused on their extraction methods,benefits and characteristics,with the case of research results as the center.In addition,the characterization means of natural plant dyestuffs were briefly introduced in terms of the actual dyeing process,in order to provide reference for the application and development of natural plant dyestuffs.
