Description
Technical Field
The invention belongs to the technical field of immortalized flower production, and particularly relates to a method for dyeing rose immortalized flowers by using natural buddleja officinalis anthocyanidin.
Background
The immortal flower, also called fresh-keeping flower, ecological flower, never withered fresh flower, is produced by adopting modern technological means, the dried flowers prepared from fresh cut flowers such as roses, hydrangea, chrysanthemums, carnations, butterfly orchids and the like through a series of processing technologies such as dehydration, decoloration, drying, dyeing and the like can be preserved for a long time, and better flower forms can be maintained. The permanent flowers overcome the defects of short inserting life and short ornamental period of the fresh cut flower vase, and greatly prolong the ornamental life of the flowers. Compared with other types of dried flowers, the immortal flowers are more natural and lifelike, have high ornamental value, are widely applied to scenes such as room decoration, interior decoration, wedding activities, practical products, festival parties, relatives and friends and lovers for expressing feelings, and are deeply loved by consumers.
