Embodiment 1

[0024] Embodiment 1: the fabric is 02 crepe de chine, the door width is 114cm, the moving mode of the coloring device is adopted, the color is a two-color progressive color of light red and blue in the middle of both sides, and a plurality of liquid spray colorers 16 installed on the coloring device 14 are divided into two groups, The deepest concentration is dyeing mother liquor: diluent = 1:0 (that is, the concentration of dyeing mother liquor), and the shallowest concentration is dyeing mother liquor: diluent = 1:19 (that is, 1 / 20 of the concentration of dyeing mother liquor), the process is as follows:

[0025] Stretched silk—coloring (the moving speed of the coloring device is 10 m / min)—heating and drying or natural drying—steaming in a garden barrel steamer (steam pressure 0.8kg / cm 2 , 30 minutes) - rope washing, color fixation - stenter drying - finished product.

[0026] Stretch the fabric 11 on the stretcher frame 13 with track 12, the coloring device 14 moves along t...

Embodiment 2

[0027] Embodiment 2: the fabric is 16 electric power spinning, the door width is 114cm, the fabric is moved, the equipment is a hot air stenter, the color is green monochromatic progressive color, and a plurality of liquid spray colorers 16 installed on the coloring device 14 are one Group, the deepest concentration is the dyeing mother liquor: diluent = 1:0 (that is, the concentration of the dyeing mother liquor), the lightest concentration is the dyeing mother liquor: diluent = 1:24 (that is, 1 / 25 of the concentration of the dyeing mother liquor), the process as follows:

[0028] Fabric rolling - coloring, drying (vehicle speed 15 m / min, oven temperature 120°C) - steaming (continuous steamer, temperature 102°C, time 30 minutes) - open width washing (open width washing machine or Jig dyeing machine washing), color fixation - woolen blanket machine drying - finished product.

[0029] The coloring device 14 is fixed, and the coloring device 14 colors the fabric when the fabric...

Abstract

The invention discloses a fabric gradual color dyeing technique and an employed coloration device thereof. The present gradual color dyeing method can only dye the gradual color of one color at a time and can only dye two colors at utmost, therefore, the yield and the quantity of colors are limited to a certain extent. The invention colors the fabrics by the coloration device, the employed coloration device comprises a plurality of spray coloration apparatuses capable of regulating the concentration of a dyeing liquid, the plurality of spray coloration apparatuses are arrayed in one group or more than two groups, each spray coloration apparatus operates individually to independently regulate the concentration of the dyeing liquid sprayed by each spray coloration apparatus so that the concentration of the dyeing liquid sprayed by each group of the spray coloration apparatuses is regulated to be incremented or decremented in sequence, thus generating, on the fabric, the gradual colors of one or more than two colors at a time.

Description

technical field [0001] The invention relates to the field of fabric dyeing, in particular to a fabric progressive color dyeing process. Background technique [0002] At present, progressive color dyeing of thin fabrics such as silk is mainly carried out on star frame or square frame hanging dyeing equipment. The mature process widely used is the dye addition method. The specific method is as follows: first dye the light color, and align the shade Finally, take out 1 / 3 of the dye solution, add a certain amount of dye to dye the mid-range color, then take out 1 / 3 of the dye solution, add dye and then dye the dark color. Due to the adoption of the hanging dyeing process, the bath ratio is large (generally 1:30-50), and the discharged dyeing sewage is large and high in concentration, which not only causes an increase in energy and raw material consumption, but also increases the burden on the environment. This process has high requirements for operation, especially for thin pl...
