Embodiment 1
[0029] In this example, see figure 1 and figure 2, a continuous dyeing device for cotton fabrics with reactive dyes using spray wet steaming, mainly including a steaming box and a fabric conveying device, the fabric conveying device is mainly composed of a series of rubber rollers, the steaming box mainly includes a box body 7 and several synchronous The cloth guide roller 1 that rotates, the fabric after the wet coloring enters the cloth inlet 10 of the steam box, and after steaming and fixing the color in the steam box, it comes out from the cloth outlet 11 of the steam box to complete the dyeing process of the fabric.
[0030] In this example, see figure 1 and figure 2 , the continuous dyeing device of reactive dyes on cotton fabrics using spray wet steaming also includes atomization device, atomization box 5 and suction device; the fabric is first fed into the cloth by the cloth guide roller 1, and then the fabric surface wrinkles are eliminated by the spreader roller ...
Embodiment 2
[0058] This embodiment is basically the same as Embodiment 1, especially in that:
[0059] In this embodiment, the slope of the edge of the atomization box 5 is at an angle of 65° to the surface of the fabric. The liquid droplets condensed on the side slope of the atomization box 5 will not drop on the cloth surface, but flow into the liquid guide groove 6 along the side slope, so as to leave the area above the fabric and collect them. The width of the cloth surface covered by the atomization box 5 is the same as the width of the fabric, and when dyeing, the required standard for the area of the cloth surface that is not covered by the fog droplets is reached; the atomization box 5 forms a right-angled triangle box-shaped structure with only one opening, The opening front of the atomizing box is a spraying device, and the atomizing box 5 should have sufficient height to ensure that the colored mist drops can not escape the atomizing box 5 after spraying. The size of atomizi...
Embodiment 3
[0062] This embodiment is basically the same as the previous embodiment, and the special features are:
[0063] In this embodiment, by adjusting the spray volume of the spray gun 3, the size of the droplets, the suction wind strength of the suction device, and the formula of the dye liquor mixture, it is possible to carry out single-side coloring, positive and negative coloring of the front and back, and coloring of the same color on the front and back. Any one of three different dyeing processes. Cotton fabrics with different coloring effects can be dyed by using this device for dyeing processing, and at the same time have high soaping fastness and rubbing fastness, which can meet the needs of wearing performance. Adopt the dyeing device of this embodiment to spray and steam the reactive dyes for dyeing, the liquid carrying rate of the fabric before steaming is as low as 15% to 35%, which is suitable for dyeing cotton fabrics with reactive dyes, and avoids the high liquid car...
