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...

Abstract

The invention discloses a discharge printing process of deep grounding color cotton crepe, and belongs to the technical field of crepe printing. The process flow sequentially comprises the following steps of carrying out sketch drafting, plate making, stretching, printing, drying, steaming and baking, water washing, wrinkling and post finishing, wherein the printing step is specifically characterized in that the adding frequency of a printing slurry in the printing process is 1 time / (3-8 min), the addition amount of the printing slurry in a single time is 0.5-1.5 kg, and the replacement frequency of the printing slurry on a pattern plate is 1 time / (20-40 min); the steaming and baking step is specifically characterized in that the steaming temperature is 107 DEG C to 115 DEG C, and the steaming time is 500-700s; and after steaming, baking is carried out, wherein the baking temperature is 125-135 DEG C, and the baking time is 250-350 s. According to the process provided by the invention,light colored patterns can be printed on the dark cotton crepe, the white color light after whitening can be effectively improved, the whiteness of pattern-shaped lines is uniform, and the flower-shaped lines are not prone to opposite sticking during water washing.

Description

technical field [0001] The invention discloses a discharge dyeing printing process for cotton crepe cloth with deep background color, which belongs to the technical field of crepe cloth printing. Background technique [0002] Crepe, also known as crepe, is a thin plain cotton fabric with uniform longitudinal wrinkles. Its characteristic is that ordinary cotton yarn is used in the warp direction, and strong twisted yarn is used in the weft direction. The warp density in the fabric is greater than the weft density. After the fabric is woven into a loose dyeing and finishing process, the weft direction shrinks by about 30%, thus forming uniform wrinkles. The raw materials used are pure cotton or polyester cotton. Crepe is light and thin, with natural and long-lasting wrinkles, high elasticity, cool and soft hand feeling, and comfortable to wear, which is deeply loved by consumers. [0003] The applicant found in the research that the existing dark background cotton crepe has ...
