It is described in detail for woven fabric dyeing：
One, it dyes
As shown in figure 3, needed successively after pouring water in cylinder 1 in dyeing course by three steps of heating, heat preservation and cooling,
Wherein B points represent 50~80 DEG C, and CD temperature sections are heat preservation temperature section, and holding temperature is 135 DEG C, soaking time 40min.
In the temperature rise period, it is divided into AB temperature sections and BC temperature sections：
In AB temperature sections, there are three types of heating modes：The first, directly enters hot water（Water at low temperature or high-temperature water）；Second, with height
Warm water heats up, and heating hot water flows back to water at low temperature storage box；The third, is heated up with steam, and the condensed water of generation, which flows back to high-temperature water, to be deposited
Storage tank or boiler.Wherein, first way is optimal on water-saving, energy-saving effect at this stage.
In BC temperature sections：Since required temperature is excessively high, therefore heating mode heats up for steam, and generation condensed water, which flows back to high-temperature water, to be deposited
Storage tank or boiler.
In CD temperature sections：Steam insulation, the condensed water of generation is used to flow back in high-temperature water storage box or boiler in the step.
In temperature-fall period, it is divided into DE temperature sections and EF temperature sections：
DE temperature sections：Cooling method can use normal-temperature water or low temperature water cooling, cooling water to flow back to high-temperature water storage box.In the rank
Cooled down using normal-temperature water if requiring cooling rate fast according to technological requirement selection water in section；If wanted to cooling rate
It asks not high and initial temperature is higher, then cooled down using water at low temperature, using water at low temperature cooling energy saving, water-saving better, by
In full resistance polyester fiber knitting fabric DE sections to normal-temperature water or low temperature water cooling all can, therefore it is preferred that water at low temperature cools down.
EF temperature sections：There are three types of cooling method, the first, direct small flow is intake to cylinder 1 to cool down, and this method can cause water
The wasting of resources；Second, normal-temperature water is cooled down by heat exchanger, and temperature lowering water flows back to water at low temperature storage box；The third, in E（Temperature 90
℃）Locate in line, cylinder 1 selects into high-temperature water, to realize to restore to wash with RC and dock, preferably the third.
Two, RC reduction is washed：
As shown in figure 4, needed successively after pouring water in cylinder 1 during RC reduction is washed by heating up and keeping the temperature two steps,
Wherein holding temperature is 80 DEG C, soaking time 20min.
In the temperature rise period, there are two types of heating modes：The first, is heated up with steam, and condensed water flows back to high-temperature water storage box or pot
Stove；Second, cylinder 1 is selected into high-temperature water, preferably second of heating mode.
Holding stage：With steam insulation, generates condensed water and flow back to high-temperature water storage box or boiler.
Three, hot water wash：
As shown in figure 5, needed successively after pouring water in cylinder 1 during hot water wash by heating up and keeping the temperature two steps,
Middle holding temperature is 80 DEG C, soaking time 20min.
In the temperature rise period, there are two types of heating modes：The first, is heated up with steam, and condensed water flows back to high-temperature water storage box or pot
Stove；Second, cylinder 1 is selected into high-temperature water, preferably second of heating mode.
Holding stage：With steam insulation, generates condensed water and flow back to high-temperature water storage box or boiler.
Four, it neutralizes and washes：
As shown in fig. 6, needed successively after pouring water in cylinder 1 in and during washing by heating up and keeping the temperature two steps,
Middle holding temperature is 50 DEG C, soaking time 20min.
In the temperature rise period, there are four types of heating modes：The first, is heated up with steam, and condensed water flows back to high-temperature water storage box or pot
Stove；It second, is heated up with high-temperature-hot-water, heating hot water return to water at low temperature storage box；The third, cylinder 1 is directly into water at low temperature；
4th kind, in appropriate proportion to cylinder 1 into high-temperature water and normal-temperature water, preferred the third heating mode.
In holding stage, there are two types of heat preserving modes：The first, is kept the temperature with high-temperature water, and heat preservation hot water stream returns water at low temperature storage
Case；Second, high-temperature water storage box or boiler are flowed back to the condensed water of steam insulation, generation, and since steam production needs energy
Consumption and resource consumption, therefore it is preferred that the first heat preserving mode.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
