Embodiment 1

[0045] Example 1: Light color I (dye dosage X≤0.5%) printing

[0046] ⑴The printing process, such as figure 1 Shown:

[0047] ⑵ Formula and process description:

[0048] 1) Pretreatment (cotton fiber graft modification) formula and process:

[0049] Cotton grafting agent HS: 30 g / L, two soaking and two rolling (at room temperature, with 70-80% liquid), and drying at 105-120°C (3-5min).

[0050] Grafting agent HS for cotton was provided by Zhejiang Huasheng Chemical Co., Ltd.

[0051] 2) Color paste formula and instructions:

[0052] Reactive dye 0.05%, urea 1%, 3-4% synthetic thickener slurry 70%, ammonia water 1%, add water to 100%;

[0053] 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 by Hangzhou...

Embodiment 2

[0057] Example 2: Light color II (dye dosage X≤0.5%) printing

[0058] ⑴The printing process, such as figure 1 Shown:

[0059] ⑵ Formula and process description:

[0060] 1) Pretreatment (cotton fiber graft modification) formula and process:

[0061] Cotton grafting agent HS: 40 g / L, two soaking and two rolling (room temperature, 70-80% liquid), drying at 105-120°C (3-5min).

[0062] Grafting agent HS for cotton was provided by Zhejiang Huasheng Chemical Co., Ltd.

[0063] 2) Color paste formula and instructions:

[0064] Reactive dye 0.2%, urea 1.5%, 3-4% synthetic thickener slurry 65%, reinforcing agent 2%, softener 2%; ammonia water 2%, add water to 100%;

[0065] 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 ac...

Embodiment 3

[0070] Example 3: Light color III (dye dosage X≤0.5%) printing

[0071] ⑴The printing process, such as figure 1 Shown:

[0072] ⑵ Formula and process description:

[0073] 1) Pretreatment (cotton fiber graft modification) formula and process:

[0074] Cotton grafting agent HS: 50 g / L, two dipping and two padding (at room temperature, with 70-80% liquid), and drying at 105-120°C (3-5min).

[0075] Grafting agent HS for cotton was provided by Zhejiang Huasheng Chemical Co., Ltd.

[0076] 2) Color paste formula and instructions:

[0077] Reactive dye 0.5%, urea 2%, 3-4% synthetic thickener slurry 60%, reinforcing agent 5%, softener 5%; triethanolamine 2%, add water to 100%;

[0078] The same amount of dye is low, and the floating color is less after printing and steaming, and generally no washing and desizing are required. Paste in color paste

[0079] All-purpose synthetic thickener pulp (low solid content, good hand feeling), synthetic thickener (polyacrylic acid) is pro...

Abstract

The invention discloses a cotton fabric reactive dye printing method with small water volume. A light color printing comprises the steps of: carrying out grafting modification on cotton fiber to introduce cation groups into cotton fiber molecules and increase adsorption rate of anion reactive dye, colouring (anchorage) rate of the reactive dye and color fastness; meanwhile, employing a synthesis thickening agent with low solid content as a printing color paste to reduce solid content in a slurry of the color paste; adding reinforcing agent and softener into the color paste to further enhance color fastness and hand feel of the printing fabric. The printing fabric is washing-free after printing. As for medium and dark color printing, modified sodium alginate is employed as protoplasm of the printing color paste to enhance washability, thereby reducing time and water amount for washing and realizing light washing. Processes of pattern design, printing board preparation, printing, steaming and after-treatment are the same as a traditional technology. The method of the invention can shorten dye printing technology, save water and reduce sewage discharge.

Description

[0001] This application is a divisional application for "Cotton Fabric Reactive Dye Printing Method with Less Water Volume", [0002] The original application date was November 23, 2009, and the application number was 200910154627.1. technical field [0003] The invention relates to a textile printing method, in particular to a cotton fabric reactive dye printing method with less water. Background technique [0004] At present, there are two types of cotton fabric printing: pigment printing and dye printing. [0005] 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, pig...
