example 1
[0037] Preparation of mordant printing paste for red madder printing fabric: raw material weight ratio:
[0038] Mordant 60kg
[0039] Thickener 170kg
[0040] Penetrant 70kg
[0041] Anti-seepage agent 70kg
[0042] Total 370kg
[0043] The mordant is alum, the thickener is CMC, the penetrating agent is a nonionic surfactant JFC, and the anti-seepage agent is a semi-emulsified paste containing kerosene. It will be prepared by mixing and stirring, and the final viscosity of the printing paste will reach 200-400cps.
[0044] Use this printing paste to print the fabric, and the process is that the fabric is printed, baked, washed and dried. Baking temperature: 145-150°C, time: 3min. After drying, it becomes as attached figure 1 Prints shown.
example 2
[0046] Preparation of printing paste for yellow cypress printing fabric: Raw material weight ratio:
[0047] Mordant 90kg
[0048] Thickener 190kg
[0049] Penetrant 70kg
[0050] Anti-seepage agent 80kg
[0051] Total 430kg
[0052] The mordant is loess, the thickener is CMC, the penetrating agent is nonionic surfactant JFC, and the anti-seepage agent is semi-emulsion paste containing kerosene. It will be prepared by mixing and stirring, and the final viscosity of the printing paste will reach 200-400cps.
[0053] Use this printing paste to print the fabric. The process is that the fabric is printed, steamed, washed and dried. Steaming temperature: 130-140°C, time: 3min. After drying, it becomes as attached figure 2 Prints shown.
example 3
[0055] Preparation of printing paste for gray Galla-colored printed fabric: Raw material weight ratio:
[0056] Mordant 90kg
[0057] Thickener 210kg
[0058] Penetrant 80kg
[0059] Anti-seepage agent 70kg
[0060] Total 450kg
[0061]The mordant is alum, the thickener is CMC, the penetrating agent is a nonionic surfactant JFC, and the anti-seepage agent is a semi-emulsified paste containing kerosene. It will be prepared by mixing and stirring, and the final viscosity of the printing paste will reach 200-400cps.
[0062] Use this printing paste to print the fabric, and the process is that the fabric is printed, baked, washed and dried. Baking temperature: 145-150°C, time: 3min. After drying, it becomes as attached image 3 Prints shown.
