Examples
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...
