The pattern is transferred to the printed textiles, and the large samples can be officially printed after confirmation by the customer. This results in time-consuming and energy-intensive production, and environmental and economic costs are high.

Abstract

L'invention concerne un liquide de prétraitement pour impression à jet d'encre numérique par transfert à froid et son procédé d'application. Le liquide de prétraitement pour impression à jet d'encre numérique par transfert à froid comprend de l'amidon pseudo-plastique éthérifié ayant un comportement rhéologique, un agent alcalin, de l'urée et de l'eau. Lors du processus de calibrage pour rotative, un tissu à imprimer est traité par le liquide de prétraitement puis mélangé avec un milieu d'impression par transfert jet d'encre numérique, et des motifs d'impression par jets sont transférés du milieu vers le tissu à l'aide d'une machine d'impression par transfert. Le liquide de prétraitement peut efficacement empêcher le transfert de colorants vers l'intérieur du tissu afin d'augmenter le taux d'absorption superficielle des colorants du tissu. En cas de quantité d'encre identique, la couleur du produit est plus profonde que celle de l'impression par transfert à froid classique.
