Embodiment 1

[0028] This embodiment provides a continuous tie-dyeing device suitable for knitted fabrics. refer to figure 1 , The continuous tie-dyeing equipment includes a cloth feeding device 100, a dyeing device 200, a color fixing device 300, a rerolling device 400, a washing device 500, a rerolling device 600, and a cloth outlet device 700 arranged in sequence.

[0029] Wherein, the cloth feeding device 100 is used to receive and flatten the knitted fabric to be dyed, and send the knitted fabric to the dyeing device 200 . Such as figure 2 As shown, the cloth feeding device 100 includes a cloth feeding frame 1 , a tensioner 2 , and a photoelectric plummet 3 . The cloth feeding frame 1 can realize the cloth feeding of the knitted fabric, and the knitted fabric passes through the tensioner 2 and the photoelectric centering device 3 in sequence to realize spreading and centering, so that the knitted fabric is fed into the dyeing device 2 flatly and without wrinkles.

[0030] The dyein...

Embodiment 2

[0048] Dyeing object: pure cotton knitted terry cloth.

[0049] The dye formula is as follows:

[0050] Reactive black L-D: 60g / l;

[0051] Active Red L-S: 6g / l;

[0052] Active yellow brown: 12g / l;

[0053] Caustic soda: 12g / l;

[0054] Penetrant: 4g / l;

[0055] Wherein, the solvent is water.

[0056] The dyeing process is as follows:

[0057] Weighing and chemicals.

[0058] The dye liquor is added into the feed tank of the dyeing device 200 through an automatic feeding system. Set the operating parameters of the continuous tie-dyeing equipment, including the cloth feeding speed of the cloth feeding device 100, the temperature in the color fixing box 8, the target cloth surface tension, and the like. Wherein, the temperature of setting color fixing box is 100 °. Set the residence time of the knitted fabric in the color-fixing box 8 to be 60s. The target cloth surface tension set is 1.2kg.

[0059] Start the continuous tie-dyeing equipment, so that the knitted fabr...

[0070] Soda ash: 20g / l;

[0071] Penetrant: 4g / l;

[0072] Wherein, the solvent is water.

[0073] The dyeing process is as follows:

[0074] Weighing and chemicals.

[0075] The dye liquor is added into the feed tank of the dyeing device 200 through an automatic feeding system. Set the operating parameters of the continuous tie-dyeing equipment, including the cloth feeding speed of the cloth feeding device 100, the temperature in the color fixing box 8, the target cloth surface tension, and the like. Wherein, the temperature of setting color fixing box is 100 °. Set the residence time of the knitted fabric in the color-fixing box 8 to be 60s. The target cloth surface tension set is 1.2kg.

[0076] Start the continuous tie-dyeing equipment, so that the knitted fabric is sequentially subjected to the pad...

Abstract

The invention relates to the technical field of textile dyeing and finishing, in particular to dyeing equipment suitable for knitted fabric. The equipment comprises a cloth feeding device, a dyeing device, a color fixing device, a first re-rolling device, a washing device, a second re-rolling device and a cloth discharging device, wherein the cloth feeding device is used for receiving and flattening a knitted fabric to be dyed; the dyeing device is used for receiving the knitted fabric conveyed by the fabric feeding device and padding the knitted fabric with first dye liquor; the color fixing device comprises at least one color fixing box and is used for fixing the color of the knitted fabric padded with the first dye liquor by using a non-aqueous color fixing medium; each color fixing box is provided with multiple large-diameter cloth guide rollers; the large-diameter cloth guide rollers are used for pulling the knitted fabric to move in the color fixing box for color fixing; the first re-rolling device is used for re-rolling the color-fixed knitted fabric; the washing device is used for washing the knitted fabric re-rolled by the first re-rolling device; the second re-rolling device is used for re-rolling the washed knitted fabric to finish dyeing; and the cloth discharging device is used for guiding the dyed knitted fabric out of the dyeing equipment.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a dyeing device suitable for knitted fabrics. Background technique [0002] At present, the dyeing process of knitted fabrics is mainly the vat dyeing process; among them, the vat dyeing process includes warp beam dyeing machine, rope dyeing machine, overflow dyeing machine, jet dyeing machine and so on. The working methods of these dyeing machines are all intermittent, resulting in low dyeing production efficiency, low degree of automation, more manpower and low energy efficiency ratio. [0003] In addition, the cold pad batch process is gradually applied to the dyeing of cotton knitted fabrics. However, the production cycle of the cold pad batch process is long, the site demand is large, and proofing is difficult. Contents of the invention [0004] In view of the above-mentioned shortcomings and existing problems of the prior art, the purpose of the pre...
