Abstract

Disclosed is a dyeing process control method of a conveyor driving rope-shaped fabric dyeing device using a number of fabric circular cycles as a control unit for controlling a dyeing process. The method is controlled by a number of fabric circular cycles as the control unit for a computer or a programmable logic controller (PLC) in order that a total dyeing process controls the dyeing process comprising the dyeing process such as a chemical adding rate, a heating/cooling rate, time intervals of holding temperature and time intervals of washing.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of controlling a dyeing process of a fabric dyeing machine on a conveyor driven rope,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to conveyor-driven fabric dyeing machines used to dye rope-based fabrics, and more particularly to the control of dyeing processes.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic diagram showing the dyeing cycle of a fabric in a conventional dyeing machine. The working principle is that the saline solution F is pressurized by the pump D2 and passes through the heat exchanger C to raise or lower the temperature to the nozzle A4 to be ejected or flowed in liquid flow ), And then return to the fabric storage tank A1 of the stainer (A). The fabric B is driven by the nozzle A4 by the fabric roller A3 (or instead of using the fabric rollers), so that the fabric B is ejected from the nozzle A4, It is driven by the induced force and circulates. The saline solution and chemicals are supplied from a service tank (E), pressurized by a pump (D1) and supplied to the dyeing circulation loop of dyeing machine (A). During circulation, the saline (F) and fabric (B) contain dyes absorbed by the fabric via heating, temperature maintenance, and cooling treatment with a heat exchanger (C) Water washing). The uniformity of dyeing (uniformity) is determined by the number of circulation cycles of the fabric during the dyeing process, that is, the number of interactions between the dye (A) and the dye (B) in the dyeing tube (A2). A large number of circulation cycles indicates that there are a large number of interactions, thus indicating that dyeing is more uniform, and that the degree of washing and dye fastness are excellent.

2, which shows a typical dyeing process used in a conventional dyeing machine, theoretically or experimentally, a conventional dyeing machine can use "time" as a control unit to perform chemical addition, heating, temperature maintenance, heating , Followed by a dyeing process including temperature holding, cooling, water washing, chemical addition, heating, temperature holding, cooling and hot water renishing in sequence. In general, control is achieved by using a computer or a programmable logic controller (PLC).

Since a conventional dyeing machine uses "time" as a control unit, it takes the same amount of time to complete the dyeing process, without regard to the actual length or weight of the fabric to be dyed. However, in an actual dyeing process, different parts of the fabric to be dyed may be different in weight, or the thickness of the fabric may be different, so that in each batch and in each tube The length of the fabric may be different. Fabrics may be of the same type, but it is generally a waste of time to adopt a dyeing process that has the same amount of dyeing time. In addition, the number of circulating cycles is different because the actual amount (length) of the fabric to be dyed in each tube or each tube of the dyeing machine during the entire dyeing process of the fabric is different. Consequently, even if the dyeing times are the same, the degree of dyeing thus obtained is different, causing problems with tube dislocation or dislocation, inconsistent dye fastness and poor reproducibility. Itself may require re-dyeing, and production quality and efficiency are poor. Significant amounts of energy and labor are consumed and can cause additional environmental pollution. This regeneration problem is a long-standing problem of dyeing factories and has not yet been overcome.

The object of the present invention is to use "time" as a control unit so that the same amount of time is taken to perform the dyeing process on the same type of fabric without regard to the actual length of the dyeing, The results of the work are different and overcome problems arising in conventional dyeing processes that result in dislocations or tube breaks, inconsistent fastness, poor reproducibility and waste of time.

In order to overcome these problems, the present invention has been made to change the control method of a conventional dyeing machine by using the number of circulation cycles of the fabric as a control unit (reference). In other words, the horizontal axis of the plot shown in Fig. 2 is changed from "time" to "number of cycle cycles of the fabric ". Thereby, regardless of the actual length of the fabric being introduced, the dyeing process is controlled based on the number of cycles of the fabric. For rope-like fabrics of very long length, the time required for the entire dyeing process is long, and for rope-like fabrics of short length, the time required for the entire dyeing process is short. Thus, in the case of the same type of fabric, the degree of dyeing and degree of washing are all the same because the number of circulation cycles employed for each dyeing tube or each batch of dyeing operation of the fabric is all small.

As a result, the tube detachment or dislocation becomes zero, the fastness is constant, reproduction 100%, production quality and efficiency increase, remarkable decrease in dyeing cost, and environmental protection through energy saving and carbon reduction.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic diagram illustrating the cycle cycle of dyeing fabrics in a conventional dyeing machine.

3 is a plot showing the dyeing process of a conveyor driven rope-on fabric dyeing machine according to the present invention.
Figure 4 is a schematic diagram showing a conveyor driven rope-based fabric dyeing machine according to the present invention.

As shown in FIG. 4, the present invention provides a conveyor driven rope-based fabric dyeing machine comprising a fabric seam disposed at a suitable location in a dyeing machine body of a conveyor driven rope-on fabric dyeing machine, a circulation time and a circulation cycle counter to provide. Since the movement of the fabric from the rear end to the front end is driven by the conveyor, the circulation speed of the fabric is synchronous with the conveyor. Thus, the circulation time of the fabric in the circulation of each cycle is adjustable, but is once selected and set by adopting a fixed speed and a fixed time. The present invention relates to a computer or a controllable logic controller (PLC) Use this fixed speed characteristic through use and use the number of cycle cycles of the fabric as the control unit for the dyeing process. As a result, as mentioned above, it is possible to reduce the dyeing time, the tube releasing agent, the disposition agent, the constant fastness, the 100% regeneration acidity, the improvement of the production quality, the increase in the production efficiency, the remarkable decrease in the manufacturing cost, Environmental protection is improved.

Figure 3 is a plot showing the dyeing process of a conveyor driven rope-on-dye dyeing machine according to the present invention, wherein the "number of circulating cycles" is the number of "circulating cycles" used as the horizontal axis of the dyeing curve shown in Figure 2 of a typical rope- Time ", and controls the dyeing process using a computer or a controllable logic controller (PLC). In other words, the processing of textile dyeing, which in turn includes chemical addition, heating, temperature maintenance, heating, temperature maintenance, cooling, washing, chemical addition, heating, temperature maintenance, cooling and hot water washing, Quot; number of circulation cycles ". This means that the amount of chemical added at each time, the temperature change achieved in each heating or cooling operation, the temperature interval of temperature maintenance, flushing, etc., are all controlled to the "number of circulation cycles" as a control unit. In this way, the total time for the dyeing process may be different for different lengths of the piece of fabric being treated by the dyeing process. For example, for a fabric of the same type, in a practical operation, a 500 kg capacity dyer consumes about half of the time used for processing 500 kg of fabric in a 250 kg fabric process, but with the same degree of dyeing and the same resultant dyeing Thereby achieving a constant regeneration acidity. This is a breakthrough innovation.
