Embodiment 1

[0014] A high-efficiency steaming production process of two-phase printing. The reactive dye is printed on the fiber as a phase first, and then the second phase is rolled. It is not limited by the fixing liquid alkali agent, and the pH value can reach more than 13. The strong alkali can promote the ionization of the fiber and the reaction rate of the dye, activate the dye and fiber to form a covalent bond, and accelerate the completion through a high-efficiency steamer; the process includes the following steps: first, pre-treat the blank.

[0015] Then there is dye single paste printing drying (first phase) without alkali and other fixing agents, in which the printing paste is a mixture of sodium alginate, polyacrylate thickener and modified starch ether; the dye is vinyl sulfone type And dual reactive group mixed dyes. The selected printing paste should have a certain coagulation effect when it encounters strong alkali and other chemicals for padding. The original paste made...

Abstract

The invention discloses a high-efficiency steaming production process by a two-phase printing process. The process comprises the following steps: reactive dye is used as a first phase to be printed on a fiber; a second phase is rolled independent of a color fixing liquid alkaline agent, alkali can promote ionization of the fiber and the reaction velocity of the dye, and lead the dye and the fiber to be activated to form covalent bond, and to speed up the completion through a high efficiency steam box. The process comprises the following steps: pretreating openpore, printing and drying single pulp by the dye without fixing agents, such as alkali and the like, rolling the fixing chemical liquid in high efficiency and short steaming efficiently; and washing and drying. The process has the characteristics of high reaction speed, steam usage conservation, high production efficiency, good dye yield and color fastness and high production quality.

Description

technical field [0001] The invention relates to a high-efficiency steaming production process for two-phase printing. Background technique [0002] The one-phase printing process of traditional cotton fabrics includes the following steps: pre-treatment of blank → printing and drying of dyes and alkali chemicals in the same paste → steaming and color fixing (102°C × 7-8min) → washing and drying. In conventional one-phase printing, since alkali and dye are printed in the same paste, a mild weak alkali agent (such as baking soda or urea) must be used to keep the dye stable and not decompose during the printing drying process. When steaming, baking soda decomposes into soda ash when heated, so the pH value is only 11, and it takes 7-8 minutes to steam and fix the color. The traditional printing process has the characteristics of slow reaction speed, large steam consumption, low production efficiency, poor color yield and color fastness, and unstable product quality.
