Embodiment 1

[0019] 18.5tex semi-combed pure cotton cloth, weight 130g / m 2 , Fabric weight 107kg.

[0020] (1) Preparation of paste: Take 30% etherified modified corn starch, 10% sodium alginate and appropriate amount of distilled water, heat and stir in a reaction kettle with a heating and stirring device at 40-60°C until the mixture becomes a transparent paste ;

[0021] (2) Preparation of color paste: take 50% of the paste prepared in step (1), 3% L-type reactive dye, 12% mixed color fixing agent, add water to 100%, stir and mix evenly; wherein, the mixed color fixing The agent is a 4:1 mixture of baking soda and urea;

[0022] (3) Printing: Immerse the pre-treated pure cotton gray cloth into the color paste prepared in step (2), and use a magnetic bar printing machine for printing treatment. The conditions are pressure 0.5MPa, speed 20m / min, and temperature gradually rising from room temperature up to 40°C.

[0023] (4) Color fixation: Dry the printed fabric in step (3) at 120°C fo...

Abstract

The invention discloses a reactive dye printing technology of pure cotton cloth. The reactive dye printing technology comprises the following steps: (1) preparing a paste material; (2) preparing a mill base; (3) printing; (4) carrying out fixation; and (5) carrying out post-treatment. The reactive dye printing technology of the pure cotton cloth is novel in thinking, simple, convenient and easily to realize; and the prepared pure cotton printed cloth has the advantages of no assistant residue, soft fabric, high color fastness and low energy consumption, does not contain a cancerogenic substance, and is green, environment-friendly, and wide in market prospect.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a reactive dye printing process for pure cotton cloth. Background technique [0002] With the development of science and technology and the improvement of people's living standards, consumers have transitioned from simply focusing on fabric texture to expecting health, environmental protection and fashion coordination. It is an effective means to realize this trend to change the appearance, feel, fashion and safety and environmental protection performance of fabrics through dyeing, printing process and selection of raw materials for dyeing and printing. However, when the existing pure cotton fabrics are printed, there are the following problems: 1. The color fixation and hydrolysis are not synchronized, and the printing and dyeing effect is poor; 2. The safety of printing and dyeing raw materials is poor, and the consumption is large, which is easy to cause wa...
