Abstract
Description
- The invention relates to an overflow dyeing system of atomized airflow dyeing machine and method for wet processing thereof.
- In prior art of airflow dyeing machines, greige fabric is transmitted by air flow through guide roller while preprocessing and dyeing. Liquor ratio is quite low, generally 1:3-4 for pure cotton greige fabric and 1:2-4 for polyester fabric, thus saving water consumption and dyestuff and reducing wastewater discharging volume. So far, these dyeing machines are environment-friendly for preprocessing and dyeing greige fabric. However, an airflow dyeing machine uses air from an air blower as major drives to transmit greige fabric; the air blower has big power and consumes large amounts of electricity. Especially, when the dyeing temperature is at 130°C, the actual electricity consumption is over twice of the consumption at normal temperature and pressure below 100°C; in addition, while dyeing polyester fabric or T/C greige fabric at 130°C, the dyed fabric has fish-skin wrinkles which cannot be flattened even through after-finishing, high-temperature tentering and finalizing. Therefore, dyeing with airflow dyeing machines at high temperature and high pressure around 130°C has certain influences on the quality of polyester fabric or T/C greige fabric, and airflow dyeing machines have lots of inadequacies, like big power consumption.
- The object of the invention is to provide in view of the problems in the prior art a technical program of an overflow dyeing system of atomized airflow dyeing machine and method for wet processing thereof.
- The invention effectively saves electricity and provides solutions to the dyeing limitation of airflow dyeing machines. Take a single-tube dyeing machine as an example, this system has added an overflow nozzle at the front end of the original airflow nozzle as well as an auxiliary pump with the same power of the main pump; a filter I has also been added between the main pump, auxiliary pump and the heat exchanger. In this way, the air blower does not have to be turned on; instead two pumps are started at the same time to form an overflow dyeing system for the airflow dyeing machine. Both the airflow dyeing and overflow dyeing systems of the airflow dyeing machine as per technological requirements are controlled via PLC program. During airflow dyeing operation, the greige fabric in the dyeing machine is transmitted by the air from air blower and guide roller and continuously contacts and circulates in the dye liquor in the vessel that is pumped by the main pump, atomized by the heat exchanger and sprayed out by the airflow nozzle and circulate to finish the process of preprocessing, dyeing and washing, etc. During overflow dyeing operation, the air blower stops working; the greige fabric in the dyeing machine is transmitted by the guide roller and sufficient flow rate and flow generated by the main pump and auxiliary pump and continuously contacts and circulates in the dye liquor in the vessel that is pumped by two pumps and flows through the heat exchanger and overflow nozzle, etc. to finish the dyeing and washing process. Generally, the overflow nozzle has a water flow five times bigger than the airflow nozzle. This invention has both the airflow dyeing system and the overflow dyeing system, which have prevented polyester fabric wrinkling while being dyed in high-temperature air flow at 130°C and reduced electricity consumption by air blower during the process of airflow dyeing at high temperature. This invention saves energy and enlarges the application of dyeing machine.

Afilter I 10 is coordinately configured between themain pump 13 and the heat exchanger 8. An overflow nozzle 4 is connected on the output tube of the heat exchanger 8 through an overflow nozzleconnection tube valve 6 and placed above the airflow nozzle 5. Anauxiliary pump 12 is added on the tube of themain pump 13; a connection valve I 11 and a connection valve II 14 are respectively configured on the tubes of both ends of theauxiliary pump 12. A connection valve III 19 is configured between thewater inlet valve 18 and thedrain valve 20. Theauxiliary pump 12 and themain pump 13 are of the same model. - A method for wet processing of overflow dyeing system of atomized dyeing machine to process a jacquard greige fabric cross-woven with polyester and modified polyester, comprising the processing steps of:
- 1) Degreasing preprocessing: adding water and dyes and circulating the greige fabric at the temperature of 60°C; directly rising the temperature to 90°C and holding for 30~40min; directly dropping the temperature to 70°C; finishing preprocessing and draining water; and then continuously adding 60°C hot water and washing for 15min.
- 2) Alkali deweighting: adding water and dyes and circulating the greige fabric at the temperature of 60°C; directly rising the temperature to 90°C and holding for 40~60min; directly dropping the temperature to 60°C; finishing alkali deweighting and draining water; and then continuously adding 60°C hot water and washing for 15min; washing with neutralization water for 5min and fresh water for 5min.
- 3) Dyeing polyester with disperse dyes: adding water and dyes and circulating the greige fabric at the temperature of 60°C; rising the temperature to 130°C at a rate of 1~2°C/min and holding for 40~60min; directly dropping the temperature to below 80°C; finishing polyester dyeing and draining water; and then adding 60°C hot water, circulating the greige fabric, and draining water after 10min washing.
- 4) Dyeing modified polyester with cationic dyes: adding water and dyes and circulating the greige fabric at the temperature of 70°C; rising the temperature to 85°C at a rate of 1°C/min, then to 98°C at a rate of 2°C/min and holding for 40~60min; dropping the temperature to 80°C; finishing dyeing and draining water; and then adding 60°C hot water and washing for 10min.

- When the dyeing machine circulates normally, the air blower 9 starts blowing; the dyeing machine transmits one end of the
greige fabric 2 through theguide roller 3, the overflow nozzle 4 and the airflow nozzle 5 into thevessel 1; as thegreige fabric 2 is totally transmitted into the vessel, the head end and the tail end of thegreige fabric 2 are connected to be like a rope, which keeps circulating and transmitting under the effect of theguide roller 3 and the force of air flow generated by the air blower 9; at the same time, thedrain valve 20,auxiliary pump 12, connection valve I 11, connection valve II 14 and overflow nozzleconnection tube valve 6 close while the connection valve III 19,water inlet valve 18 andmain pump 13 open. Water runs through the heat exchanger 8 and airflow nozzle 5, continuously contacts the transmittinggreige fabric 2, flows inside the vessel and downwards to the bottom of the vessel, goes through the filter II 21 and connection valve III 19, and at last returns back to themain pump 13 for water circulation. When the vessel has a certain water level, thewater inlet valve 18 closes. Water keeps flowing and circulation inside the system. - When temperature rising or dropping is needed during the processing steps, steam or cooling water goes into the heat exchanger 8 and indirectly contacts the water inside the
vessel 1, thus rising or dropping the temperature of the water inside thevessel 1. Through the process, themain pump 13 supplies power for water circulation inside the vessel. - When feeding is needed during the processing steps, additives or dyes are diluted in the
feeding vat 15 in advance. Thecharge pump 16 starts while feeding. Thefeeding valve 17 opens. Dyes are fed evenly. - When continuous washing is needed during the processing steps, the
drain valve 20 andwater inlet valve 18 open; at the same time the connection valve III 19,auxiliary pump 12, connection valve I 11, connection valve II 14 and overflow nozzleconnection tube valve 6 close. Fresh water is sucked in by themain pump 13, goes through the filter I 10 to the heat exchanger 8, and continuously washes the transmittinggreige fabric 2 via the airflow nozzle 5. - While dyeing at 130°C as described in step 3), the
main pump 13,auxiliary pump 12, connection valve I 11, connection valve II 14, connection valve III 19,water inlet valve 18 and overflow nozzleconnection tube valve 6 open; the air blower 9, airflow nozzle connection tube valve 7 anddrain valve 20 close. The greige fabric circulates inside thevessel 1 under the effect of the overflow nozzle 4. - The invention effectively saves electricity and provides solutions to the dyeing limitation of airflow dyeing machines. Take a single-tube dyeing machine as an example, this system has added an overflow nozzle 4 at the front end of the original airflow nozzle as well as an
auxiliary pump 12 with the same power of themain pump 13; afilter I 10 has also been added between themain pump 13,auxiliary pump 12 and the heat exchanger 8. In this way, the air blower 9 does not have to be turned on; instead two pumps are started at the same time to form an overflow dyeing system for the airflow dyeing machine. Both the airflow dyeing and overflow dyeing systems of the airflow dyeing machine as per technological requirements are controlled via PLC program. During airflow dyeing operation, thegreige fabric 2 in the dyeing machine is transmitted by the air from air blower 9 andguide roller 3 and continuously contacts and circulates in the dye liquor in thevessel 1 that is pumped by themain pump 13, atomized by the heat exchanger 8 and sprayed out by the airflow nozzle 5 and circulate to finish the process of preprocessing, dyeing and washing, etc. During overflow dyeing operation, the air blower 9 stops working; thegreige fabric 2 in the dyeing machine is transmitted by theguide roller 3 and sufficient flow rate and flow generated by themain pump 13 andauxiliary pump 12 and continuously contacts and circulates in the dye liquor in thevessel 1 that is pumped by two pumps and flows through the heat exchanger 8 and overflow nozzle 4, etc. to finish the dyeing and washing process.
