Abstract

La présente invention concerne un procédé de coloration profonde et à haute concentration pour nanocellulose. Ledit procédé comprend les étapes consistant à: ajouter un sel d'électrolyte fort à une solution aqueuse de nanocellulose, effectuer une centrifugation, puis ajouter de l'éthanol et de l'eau pour formuler une solution mélangée de nanocellulose; ajouter un colorant actif, un alcali ou un sel d'acide faible fortement alcalin dans la solution mélangée, puis chauffer, condenser et refluer la solution; et après l'achèvement de la réaction, réaliser une centrifugation, et collecter le précipité, de façon à obtenir une nanocellulose colorée profonde. La concentration de la nanocellulose dans la présente invention peut être augmentée à 5% - 10% de 0,5% - 2% de nanocellulose commune dans une réaction de coloration, ce qui permet d'augmenter le taux de greffage. L'absorption de colorant d'un colorant peut être augmentée à 50% - 70% de 20% - 40% de nanocellulose commune, ce qui permet d'augmenter le taux d'utilisation du colorant. La présente invention est avantageuse pour le traitement des eaux usées de réaction. En outre, la nanocellulose colorée préparée par la présente invention présente une très bonne stabilité, ne se décolore pas facilement, est de petite taille et présente une aptitude à la coloration élevée, étant souhaitable pour être appliquée dans des domaines tels que l'impression à jet d'encre de nanocellulose et l'anti-contrefaçon de papier, ayant une grande valeur pratique.
