Abstract

The invention discloses a printing process of raffia braided fabric, and belongs to the technical field of printing processes. The preparation method comprises the following steps of 1) preparing andsynthesizing glue paste (hydroxyethyl saponin gum); adding urea into the synthetic gum paste, scattering a weakly acidic dye according to a mass ratio of the synthetic gum paste to the urea to the weakly acidic dye of 100: (3-5.5): (1.5-3), and uniformly stirring to obtain a printing paste; printing the raffia braided fabric on a machine by using the printing paste to obtain a printed braided fabric; (2) drying the braided fabric printed in the step (1), (3) steaming the braided fabric obtained in the step (2), and (4) washing the steamed and color-fixed braided fabric obtained in the step (3)with water. The printing obtained by the process is clear in printing outline, simple and feasible, and the mechanical performance of raffia is not affected.

Description

technical field [0001] The invention relates to a printing process of raffia braided fabric, belonging to the technical field of printing process. Background technique [0002] Raffia, also known as wishing rope or love grass, is called raffia in English. It is produced in Madagascar, Africa. Raffia is imported forage and is expensive. Raffia has strong toughness and is considered to have the best physical and mechanical properties among known natural plant fibers. The grass is smooth on the outside and refreshing on the inside, not afraid of water and extremely strong. It is widely used in knitted products, such as hats, straw mats, pendants, ropes, shoes, etc., and is deeply loved by people. Observed under an electron microscope, the microstructure of the raffia fiber is layered, the outer layer is a uniformly arranged sheet structure, and the bottom layer is a honeycomb structure. The surface of the fiber is smooth, the elongation is between 2% and 4%, it has high break...
