specific Embodiment approach 1

[0023] Specific Embodiment 1: This embodiment provides a color printing and dyeing process of reactive ink dyes on linen fabrics, generally through three stages of adsorption, diffusion and fixation, the first two are the dyeing stage, and the last is the fixation stage, the specific operation Proceed as follows:

[0024] 1. Sizing, drying and baking.

[0025] Use a roller sizing machine or a screen to sizing the linen fabric on one side. The sizing should be uniform. Too thick coating will affect the running of the cloth, and too thin will affect the color density. The drying time depends on the speed of the sizing machine. The drying temperature is controlled at 70-95°C. It is dry when it enters the rolling system, and the baking time is 2-3 minutes. The amount of padding sizing is about 75-80%, and the sizing of the stencil coating is based on just reaching the back of the cloth.

[0026] The sizing agent is one or more polymer substances that can form a film. Its action ...

specific Embodiment approach 2

[0040] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the sizing agent formula (weight ratio) is: 15 parts of paste, 3.5 parts of sodium bicarbonate, 4.0 parts of urea, 3.6 parts of anhydrous sodium sulfate, Anti-staining salt 1.6 parts, water 72.3 parts.

specific Embodiment approach 3

[0041] Specific embodiment three: this embodiment is different from specific embodiment one in that the sizing agent formula (weight ratio) is: 10 parts of paste, 4.5 parts of sodium bicarbonate, 4.5 parts of urea, 4.3 parts of anhydrous sodium sulfate, Anti-staining salt 2.0 parts, water 74.7 parts.

Abstract

A color printing and dyeing technology of an active ink dye on linen fabric relates to a linen active color printing and dyeing technology. The invention aims to solve the technical problem about linen printing and dyeing at home and aboard. The printing and dyeing technology provided by the invention comprises the following steps: 1, sizing, drying and curing; 2, active digital jet-printing and drying; 3, wet steaming for color fixation; and 4, washing, soaping, washing, drying and shaping. According to the invention, active ink is, for the first time, transferred to linen fabric in a non-contact way. Through tests and application, color printing and dyeing is successfully realized, and the technology has put into production. Thus, the natural fiber has a wider development space. The technology provided by the invention is a brand-new printing mode which is different from the tradition.

Description

technical field [0001] The invention relates to a color process for printing and dyeing flax with active ink. Background technique [0002] Flax belongs to the earliest natural fibers used by humans, and is the only bundled plant fiber in natural fibers, with a natural spindle-shaped structure and unique pectin beveled holes. Printing and dyeing is a major technical difficulty. In the past, only single-color dyeing and finishing could be carried out after spinning. Using new technology, it can realize colorization on linen, does not contain formaldehyde, and dry and wet friction can reach above 4.0 level. The high-speed digital printing machine can reach 600-800m hours. It can print directly according to the designer's design without plate making. It is a high combination of digital technology and textile industry, and it can make the colors rich and colorful. [0003] Reactive ink is a water-soluble liquid reactive dye with one or more active groups in the molecule, whic...
