Embodiment 1

[0033] This embodiment provides a continuous tie-dyeing device that can be used to implement the silk fabric dyeing method. refer to figure 1 , The continuous tie-dyeing equipment includes a cloth feeding device 1, a dyeing device 2, a color fixing box 3, a rerolling device 4, a washing device 5, and a cloth outlet device 6 arranged in sequence.

[0034] Wherein, the cloth feeding device 1 is used to receive and flatten the silk fabric to be dyed, and send the silk fabric to the dyeing device 2 . The dyeing device 2 can pad the silk fabric. Wherein, the dyeing device 2 can be provided with a uniform padding car for padding the silk fabric. Specifically, the dye liquor used for dyeing the silk fabric can be pre-configured, and the dye liquor can be added into the trough of the padder. Wherein, the content of reactive dye in the dyeing liquor is 0.1g / l-100g / l, and the content of alkali is 0.1g / l-20g / l.

[0035] The cloth feeding device 1 can be provided with a cloth feeding ...

Embodiment 2

[0052] Dyeing object: 100% silk fabric.

[0053] Configure the aqueous solution containing reactive black G with a concentration of 60g / L and sodium carbonate with a concentration of 8g / L as the dye solution.

[0054] The dye liquor is added into the feed tank of the dyeing device 2 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 1, the rotation speed of the cloth guide roller 32, the temperature in the color fixing box 3, the target cloth surface tension, etc. Wherein, the temperature of the color fixing box is set at 95°C. Set the target fabric tension to 1kg. The cloth feeding speed of the cloth feeding device 1 and the rotating speed of the cloth guide roller 32 are set so that the residence time of the 100% silk fabric in the color fixing box 3 is 180s, and the surface tension of the 100% silk fabric is maintained at 1kg.

[0055] Start the continuous...

Embodiment 3

[0062] Dyeing object: fabrics containing 95% silk and 5% wool.

[0063] Configure the aqueous solution containing reactive black G with a concentration of 20g / L and sodium carbonate with a concentration of 5g / L as the dye solution.

[0064] The dye liquor is added into the feed tank of the dyeing device 2 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 1, the rotation speed of the cloth guide roller 32, the temperature in the color fixing box 3, the target cloth surface tension, etc. Wherein, the temperature of the color fixing box is set at 90°C. Set the target fabric tension to 1.2kg. The cloth feeding speed of cloth feeding device 1 and the rotating speed of cloth guide roller 32 are set so that the residence time of the fabric containing 95% silk and 5% wool in the color fixing box 3 is 60s, and the fabric containing 95% silk and 5% wool is The surface...

Abstract

The invention relates to the technical field of textile dyeing and finishing, in particular to a silk fabric dyeing method and equipment. The method comprises the following steps of padding a first dye liquor containing a reactive dye onto a silk fabric; carrying out color fixation on the silk fabric padded with the first dye liquor by using a non-aqueous color fixation medium in a color fixation box; in the color fixation period, the maintaining the cloth surface tension of the silk fabric between 1kg and 100kg; and washing and dewatering the silk fabric subjected to color fixation so as to finish dyeing.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a silk fabric dyeing method and equipment. Background technique [0002] In the current scheme, when dyeing silk with reactive dyes, to achieve high color fastness, it needs to be carried out under alkaline conditions, and a large amount of dyeing accelerator (salt or sodium sulfate) needs to be added to accelerate the dyeing process. Adsorption on fibers. Among them, when silk is dyed, the addition of a large amount of alkali and dyeing accelerator not only accelerates the hydrolysis of the dye, resulting in a decrease in the utilization rate of the dye; Dyeing properties of silk fabrics. Contents of the invention [0003] In view of the above-mentioned shortcomings and existing problems of the prior art, the purpose of the present invention is to provide a silk fabric dyeing method and equipment to improve the utilization rate of dyestuffs and eliminate...
