Embodiment 1

[0039] Embodiment 1: light color I (dye consumption X≤0.5%) printing

[0040] (1) Printing process, such as figure 1 Shown:

[0041] (2) Formula and process description:

[0042] 1) Pretreatment (cotton fiber graft modification) formula and process:

[0043] Cotton grafting agent HS: 30g / L, double soaking and double rolling (at room temperature, 70-80% liquid), and drying at 105-120°C (3-5min).

[0044] Grafting agent HS for cotton was provided by Zhejiang Huasheng Chemical Co., Ltd.

[0045] 2) Color paste formula and instructions:

[0046] Reactive dye 0.05%, urea 1%, 3-4% synthetic thickener slurry 70%, ammonia water 1%, add water to 100%;

[0047] Due to the low amount of dye used, there is less floating color after printing and steaming, and generally no washing and desizing are required. Therefore, the paste in the color paste is all made of synthetic thickener paste (low solid content, good hand feeling), and the synthetic thickener (polyacrylic acid) is provided ...

Abstract

The invention discloses a textile printing method with a little amount of water of cotton fabric by utilizing reactive dye. Light-colored textile printing comprises the following steps: graft modification is firstly carried out on the cotton fibre to ensure that cationic group is introduced in the cotton fibre molecules, so as to increase the adsorption rate of the anionic reactive dye to increase the dye uptake (fixing) of the reactive dye and improve color fastness; and simultaneously, synthetic thickening agent with low content of solid is adopted to be served as the rawstock of the printing paste to reduce the content of solid in the sizing agent of the color paste; fixation accelerator and softening agent are added into the color paste to further improve the color fastness of the printed fabric and improve hand feeling; and washing can be avoided after textile printing. With regard to the middle and deep-coloured textile printing: the rawstock of the print paste adopts modified sodium alginate to increase the washability, thus reducing washing time and water consumption and achieving the purpose of light washing. In the textile printing, the pattern designing, flower version manufacturing, textile printing, decatizing and after finishing processes are identical to traditional process. The invention can shorten the process of dye textile printing, save water and reduce the discharge of sewage simultaneously.

Description

technical field [0001] The invention relates to a textile printing method, in particular to a cotton fabric reactive dye printing method with less water. Background technique [0002] At present, there are two types of cotton fabric printing: pigment printing and dye printing. [0003] Pigment printing is widely used, accounting for about 50-60% of the entire printing production; pigment printing is a printing process that uses adhesives to form a film on the fabric, thereby fixing the paint on the surface of the fabric to obtain the desired pattern. It has the advantages of simple operation, simplified process, generally no washing, soaping, desizing and other processes after printing, energy saving, and no waste water problem. However, pigment printing relies on an adhesive to form a film to adhere it to the fabric. Due to the existence of the adhesive, the printed (especially large-area printed) fabric has a poor feel, and the film formed by the adhesive on the pattern p...
