It is only noted that the invention is intended to be limited to the specific forms set forth herein, including any reference to the drawings, as well as any other specific forms of embodiments of the invention.

As shown in fig. 1 and 2, a first embodiment of the present invention provides a fabric dyeing system, which comprises a dyeing system and a fabric pre-shrinking system, wherein the dyeing system comprises a cloth storage tank 11, a cloth lifting roller 12, a first nozzle assembly 13 and a cloth arranging pipe 14; the cloth storage tank 11 is provided with dye liquor, the cloth lifting roller 12 is used for dragging and transferring the fabric in the cloth storage tank 11, the first nozzle assembly 13 comprises a first fabric channel 131 used for generating high-speed flowing air at least in the first fabric channel 131, and the cloth swinging pipe 14 is connected with the first nozzle assembly 13 and used for finishing the passing fabric under the synergistic action of the high-speed flowing air; the fabric preshrinking system comprises a steam conveying pipe 21 and a second nozzle assembly 22, a temperature control valve (23a, 23b) and an automatic switch valve 24 are arranged on the steam conveying pipe 21, the second nozzle assembly 22 is arranged between the cloth storage groove 11 and the cloth lifting roller 12, and the steam conveying pipe 21 is connected with the second nozzle assembly 22.

Adopt this system, the fabric preshrinking system can carry out high temperature preshrinking to the fabric, and high temperature steam meets cold fibre simultaneously, and the comdenstion water of rapid condensation can produce the swelling effect to the fabric, can improve and boil and float edulcoration effect, increases the humidity of fabric for the fabric is less through the deformation of fabric when dye liquor dyeing, and the color is more firm, and the colour is more even. The steam of this fabric preshrinking system is through locating the blowout of second nozzle assembly 22 in the combination formula nozzle, can utilize the dyeing machine that does not possess steam preshrinking function now to carry out simple transformation, and the transformation cost is low, is convenient for current printing and dyeing enterprise technical upgrade.

Preferably, the second nozzle assembly 22 includes a first nozzle inlet 221, a second nozzle inlet 222 and a second fabric passage 223, and the steam delivery pipe 21 is connected to the second nozzle inlet 222, so that high-temperature steam can be added during the fabric dyeing process to meet the requirements of a special dyeing process. The dyeing system also comprises a main cylinder body 15 for accommodating the cloth storage tank 11, and the upper part of the main cylinder body 15 is provided with a temperature sensor 151 and a pressure sensor 152; the steam delivery pipe 21 is further provided with a steam control valve 25, and the steam control valve 25 controls the delivery amount of the steam according to feedback signals of the temperature sensor 151 and the pressure sensor 152. The temperature sensor 151 and the pressure sensor 152 are used to monitor the temperature and the gas pressure in the main cylinder 15, and generally, the temperature and the gas pressure in the main cylinder 15 are positively correlated and are mainly influenced by the input amount of the high-temperature steam, but the values of the temperature sensor and the gas pressure are also influenced by the type of fabric, the volume of the dye solution, the dyeing parameters, and the like. Therefore, by simultaneously detecting the temperature and the gas pressure in the main cylinder 15, the control of the steam input amount can be performed more accurately according to the current environment in the main cylinder 15, and the control is more scientific and accurate.

Due to the corrosion of pipelines and other reasons, the introduced high-temperature steam often contains iron-bearing particles, and iron ions released by the iron-bearing particles easily influence the dyeing effect, which is more obvious under the condition of the high-temperature steam. Therefore, the steam delivery pipe 21 is further provided with a steam filter 26, and the steam filter 26 is used for filtering impurities and iron-containing particles of the steam.

Preferably, the temperature control valves (23a, 23b) include a temperature increasing valve 23a and a temperature decreasing valve 23b connected in parallel. The temperature raising valve 23a controls the flow rate of the high-temperature steam, the temperature lowering valve 23b controls the flow rate of the normal-temperature air, when the opening degree of the temperature raising valve 23a is increased, the flow rate of the high-temperature steam is increased, and the temperature of the steam sprayed out of the second nozzle assembly 22 is increased, so that the temperature of the high-temperature steam at the input end is controlled. The steam control valve 25 is arranged behind the temperature control valves (23a, 23b) so as to automatically control the amount of the introduced steam according to the pressure and the temperature in the main cylinder 15 for the high-temperature steam adjusted by the temperature control valves (23a, 23 b).

By adopting the dyeing method, the fabric is preshrunk and integrated into the dyeing machine, the existing parts of the dyeing machine are utilized, and the necessary steam source and steam control mechanism are added, so that the technology upgrading of the existing dyeing enterprises is facilitated. By adopting the dyeing method, the fabric can be preshrinked at high temperature in the dyeing machine, and meanwhile, when high-temperature steam meets cold fibers, condensed water which is condensed quickly can generate a swelling effect on the fabric, so that the boiling, bleaching and impurity removing effects can be improved, the humidity of the fabric is increased, the deformation of the fabric is reduced when the fabric is dyed by dye liquor, the color is firmer, and the color is more uniform.

Specifically, the second nozzle is higher than the first nozzle, and before or during the dyeing of the fabric, the pre-shrinking treatment of the passing fabric by spraying high-temperature steam through the second nozzle means that: before the fabric is dyed, the steam input by the steam conveying pipe 21 is sprayed to the fabric through a second nozzle; in the dyeing process, the steam input by the steam delivery pipe 21 is sprayed to the fabric through the second nozzle, and the dye is sprayed to the fabric through the first nozzle, so that high-temperature steam can be added in the dyeing process of the fabric, and the requirements of special dyeing processes are met. Before dyeing, high-temperature steam is firstly contacted with the fabric to pre-shrink the fabric, and then the fabric is contacted with the dye sprayed out from a nozzle to carry out a dyeing process; when the steam meets cold fibers, the steam can be quickly condensed into condensed water, and the condensed water is attached to the fabric and absorbed by the fabric, so that the fabric is swelled, impurities and natural pigments in the fabric can be effectively removed, the boiling bleaching degree and the impurity removal effect are improved, the subsequent process is facilitated, the adhesion performance of the dye solution is more excellent, and the dyeing is more firm.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
