Embodiment 1
[0058] Provide: 1. Fabric: cotton crepe fabric, pure cotton, navy blue, width 110±3cm; 2. The width after printing is required to be 110cm; 3. Standard sample: original flower pattern;
[0059] In this embodiment, the discharge printing process of cotton crepe cloth with deep background color adopts the following steps in sequence:
[0060] 1) Sketch:
[0061] 1.1) Width measurement: Keep the width, cut the cotton crepe fabric sample along the weft direction, and record the initial width a of the cotton crepe fabric sample in the wrinkled state as 110cm;
[0062] 1.2) Stretching and setting: Stretching and setting the cotton crepe cloth sample, the setting temperature of the tentering is 150°C, and the recorded stretching width b is 132cm;
[0063] 1.3) Stretch pattern diagram: Stretch the original pattern diagram along the width direction according to the stretch ratio M to obtain the actual pattern diagram for plate making; stretch ratio M=(stretch width b / initial width Wi...
Embodiment 2
[0073] Provided: 1. Cotton crepe fabric, pure cotton, black, width 100±3cm; 2. Original flower pattern;
[0074] In this embodiment, the discharge printing process of cotton crepe cloth with deep background color adopts the following steps:
[0075] 1) Sketch:
[0076] 1.1) Width measurement: Keep the width, cut the cotton crepe fabric sample along the weft direction, and record the initial width a of the cotton crepe fabric sample in the wrinkled state as 100cm;
[0077] 1.2) Stretching: Stretching the cotton crepe cloth sample, the setting temperature is 155°C, and the recorded stretching width b is 116cm;
[0078] 1.3) Stretch pattern diagram: Stretch the original pattern diagram along the width direction according to the stretch ratio M to obtain the actual pattern diagram for plate making; stretch ratio M=(stretch width b / initial width Width a)×100%+c=(116cm / 100cm)×100%+0.02%=118%;
[0079] 2) Plate making: select 100-mesh screen plate, make a plate according to the a...
Embodiment 3
[0088] Provided: 1. Cotton crepe fabric, pure cotton, dark green, width 90±3cm; 2. Original flower pattern;
[0089] In this embodiment, the discharge printing process of cotton crepe cloth with deep background color adopts the following steps:
[0090] 1) Sketch:
[0091] 1.1) Width measurement: Keep the width, cut the cotton crepe fabric sample along the weft direction, and record the initial width a of the cotton crepe fabric sample in the wrinkled state as 90cm;
[0092] 1.2) Stretching and setting: set the cotton crepe cloth sample to set the tenter, the setting temperature of the tenter is 153°C, and the recorded stretching width b is 102cm;
[0093] 1.3) Stretch pattern diagram: Stretch the original pattern diagram along the width direction according to the stretch ratio M to obtain the actual pattern diagram for plate making; stretch ratio M=(stretch width b / initial width Width a)×100%+c=(102cm / 90cm)×100%+0.03%=116%;
[0094] 2) Plate making: select 100-mesh screen...
