Description

Spray washing/water washing unit with drum and guide rollers placed simultaneously {SPRAY WASHING/WATER WASHING UNIT WITH DRUM AND GUIDE ROLLERS ARRANGED AT THE SAME TIME}

The present invention relates to the technical field of open width wet treatment equipment for woven fabrics, and more specifically, to improvements in the water washing tank structure of open width wet treatment equipment.

Until now, all open width wet processing facilities for woven fabrics have used the conventional upper and lower guide roller water washing tank as the main water washing unit, which also has high operating speed, low tension, and strong spraying. Although progress has been made, there has been no significant change in the overall design for decades, so no drastic changes have been achieved.

Currently commercially available cleaning equipment has a wide variety of cleaning and cleaning methods, and methods that do not use water will not be discussed here. The most important condition for water washing in a water washing unit where the drum rotor mechanism and the guide roller are placed simultaneously is to have “water”. In situations where the fabric is not sufficiently wetted and its moisture content/moisture content is insufficient, effective water washing cannot be achieved. The moisture content mentioned is the moisture content calculation formula presented in QB/T2330-2017 《Industrial Dryer》,

Calculated by

indicates the quality of the fabric after drying; G indicates the quality of completely dried fabric;

Since fabric materials are different, their moisture content/moisture content is also different depending on the water absorbency. We can use this as a starting point to analyze specific factors that affect water washing effectiveness.

Five factors affecting water cleaning effectiveness:

1) Water washing effect of fabric realized through water/water exchange; Mutual flow/exchange of clean and dirty water when adding/replenishing water; Impurities are released from the fabric through water exchange;

In the above, clean water refers to soft water, that is, the content of magnesium/calcium carbonate per liter of water is less than 6 hardness, and 1 hardness corresponds to containing 10 milligrams of magnesium/calcium carbonate per liter of water. , usually expressed as ppm, milligrams of magnesium carbonate per liter of water.

2) Water washing effect, which realizes the removal of dirt from the fabric through the relative movement between water and the fabric; In detail,

2.1. Power washing of fabric surfaces using high-pressure water spray;

2.2. Strong penetration into the fabric by vortices formed by forced convection generated by the relative motion of the rotor/drum;

2.3. When water washing is performed using upper/lower guide rollers, water flows from top to bottom on the fabric surface.

3) Water washing effect, realizing dirt removal through squeezing, that is, mechanical action force.

When using the pressure generated by the padder's rolling roller against the fabric and the pressure generated between the fabric and the guide rollers when the upper and lower guide rollers perform water washing, dirty water inside the fiber and between the fibers is deposited on the surface of the fiber. is exported to, and water exchange between clean water and water washing element 1) is carried out, and impurities are discharged from the fabric through water exchange.

The compression of the water washing element 3) of the upper/lower guide roller water washing unit designed by conventional technology realizes the water washing effect of dirt removal through mechanical force. The fabrics are water washed inside each water wash unit and then pressed before being transferred to the next water wash unit. Typically, the pressing method of the upper/lower guide roller water washing unit according to traditional technology is mainly realized through two paths: first, through a padder (but sometimes, based on process demands, using water in a vacuum); using other methods such as weaving); Second, when water washing is performed using the upper and lower guide rollers inside the upper and lower guide roller water washing unit according to the prior art, compression is performed through pressure points between the guide rollers.

4) Chemical auxiliaries;

Improves water washing efficiency by chemical reaction; Another use is to provide chemical reactions needed for fabrics, such as mercerization, bleaching, etc.

5) Temperature;

The temperature helps to improve the thermal energy of water washing. As the temperature increases, the dissolution of the auxiliary agent or cleaning agent can be accelerated, and its active molecules can move faster and penetrate the fabric quickly, Stronger dirt removal ability improves water washing efficiency; Another use is to provide the necessary reaction temperature for chemical auxiliaries, such as steaming.

In addition, the cleaning procedure also affects its water cleaning effectiveness. For example, “soaping, boiling, reducing soaping” and other processes can achieve the ideal water cleaning effect by selecting different cleaning procedures for different fabric types, dirt characteristics and degree of impurity.

The water washing element 2) inside the upper and lower guide roller water washing unit designed by the prior art mainly causes water to flow from top to bottom on the surface of the fabric when the fabric moves in and out of the upper and lower guide rollers; Taking Figure 1 as an example, the fabric flows in and out of one upper/lower guide roller water washing unit, and the length of the fabric in the transverse direction corresponding to this water washing element 2) is 4.09 meters.

Taking Figure 1 as an example, the fabric holding capacity inside the upper/lower guide roller water washing unit designed by this traditional technology is 16 meters, but when placed in an actual production environment, the fabric will only be in the first section of the front section of continuous dyeing. The front of the second upper and lower guide roller water washing unit is usually all previous processes such as singeing and desizing processing, and the dry fabric returned after processing is typically about 8% in moisture content/moisture content. / When a fabric with a moisture content of 8% enters the upper/lower guide roller non-washing unit during the front section of continuous dyeing, the fabric must first enter the liquid level L and contact the lower line guide roller R1 below the liquid level to suck the liquid. If the fabric leaves the lower line guide roller R1 and leaves the water surface, its water content/moisture content cannot fundamentally satisfy the implementation of water washing factor 2), and the upper guide roller S1 is still water washed. Since the implementation of element 3) is not satisfied, the fabric must re-enter the liquid level L and contact the lower line guide roller R2 below the liquid level to suck the liquid again, and the fabric must leave the lower line guide roller R2 and touch the water surface. Only when the water content/moisture content leaves the water washing factor 2), the implementation conditions provided in Paragraph 2.3, “When the upper/lower guide rollers carry out water washing, water flows from top to bottom on the fabric surface to achieve effective water washing,” can be satisfied, and only then will water washing begin for the first time among these water washing units. Then, when the fabric is moved to the upper line roller s5, the radial tension of the roller is applied to the surface of the fabric wrapped around the roller, causing the water washing element 3) to be implemented; The moisture inside the fabric and between the fibers is discharged from the fiber surface, water exchange occurs between clear water and the water washing element 1), and impurities are discharged from the fabric through water exchange. An abnormal situation occurs at the rear of the lower line guide roller r5. It continues all the way to the lower line guide roller r6. Next, it enters the first feather in the front section of continuous dyeing, and its moisture content/moisture content is usually about 70%.

The above statement interpreted the reason why the “effective water washing length” inside the first upper/lower guide roller water washing unit shown in Figure 1 is v5 + v6 = 1.34 meters. Before the fabric leaves the first upper/lower guide roller water washing unit in the front section of continuous dyeing, the fabric passes through the first padder, and then the moisture content/moisture content of the fabric reaches 70%, and the next step is Prepare in advance for the water washing process.

The water washing element 2) inside the upper and lower guide roller water washing unit designed by the prior art mainly causes water to flow from top to bottom on the surface of the fabric when the fabric enters and exits the upper and lower guide rollers; Likewise, if FIG. 1 is used as an example, the fabric enters and exits the second upper/lower guide roller water washing unit shown in FIG. 1 during the front section of continuous dyeing, and the fabric conforming to this water washing element 2) is The horizontal length is 4.09 meters.

When a fabric with a moisture content of 70% enters the second upper/lower guide roller unit shown in Figure 1 in the front section of continuous dyeing, the fabric must first enter the liquid level L and move to the lower line guide roller below the liquid level. It must contact r7 and begin to suck liquid, and if the fabric leaves the lower line guide roller r7 and leaves the water surface, its moisture content/moisture content cannot fundamentally satisfy the implementation of water washing factor 2), and its upper Since the implementation of the water washing element 3) is still not satisfied in the guide roller s6, the fabric must re-enter the liquid level L and contact the lower line guide roller r8 below the liquid level to suck the liquid again, and the fabric must leave r8. And only when it leaves the water surface does the moisture content/moisture content set forth in Paragraph 2.3 of Water Washing Factor 2), “When the upper/lower guide rollers perform water washing, the water flows from top to bottom on the fabric surface to achieve effective water washing.” “The implementation conditions can be satisfied, and only at this time, water washing is started for the first time among the second water washing units shown in Figure 1 in the front section of continuous dyeing. Then, when the fabric is moved to the upper line roller s7, the surface of the fabric wrapped around the roller is subjected to the radial tension of the roller, causing water washing element 3) to be implemented; The moisture inside the fabric and between the fibers is discharged from the fiber surface, and water exchange occurs between the clear water and the water washing element 1), and the impurities are discharged from the fabric through water exchange. An abnormal situation occurs after the lower line guide roller r7 and then R12. It continues all the way to. Then, in the front section of continuous dyeing, it enters the second padder shown in FIG. 1, and its moisture content/moisture content typically reaches 70%.

The above statement interpreted the reason why the “effective water washing length” inside the second upper/lower guide roller water washing unit shown in Figure 1 is v8+v9+v10+v11+v12=4.09 meters. Before the fabric leaves the upper/lower guide roller water washing unit, the fabric passes through the second padder shown in Figure 1, and then the water content/moisture content of the fabric returns to about 70%, allowing water for the next step. Prepare in advance for the cleaning process. When these two identical water wash units are connected together, the total “effective water wash length” is v5 + v6 + v8 + v9 + v10 + v11 + v12 = 5.43 meters.

Overall, the overall water washing efficiency of the conventional water washing unit is low, the number of water washing units in the overall wet treatment equipment is large, and the overall wet treatment equipment is relatively long and requires a large site area.

This design was created to solve the technical shortage of conventional water washing units, such as low overall water washing efficiency and large site area. The purpose is to provide a spray washing/water washing unit in which drums and guide rollers are placed simultaneously. There is something to do.

A cleaning roller set and a padder mechanism are installed; The first roller is installed in the upper hydraulic fluid tank and is placed below the liquid level; The upper line first drum drive mechanism is installed above the liquid level of the upper hydraulic fluid tank, and above the first drum drive mechanism, a first set of sprayers is provided to spray and wash the front of the fabric wrapped around the first drum drive mechanism. Pipes are installed; A portion of the lower line first drum driving mechanism is placed below the liquid level of the lower hydraulic fluid tank, and the front side of the lower line first drum driving mechanism is sprayed and washed on the back side of the fabric wrapped around the lower line first drum driving mechanism. A second set of sprinkler pipes are installed to proceed; The upper line second drum driving mechanism is located above the liquid level of the lower hydraulic fluid tank, and a third set of water spray pipes for spraying and washing the front of the fabric are installed on its side side; The lower line guide roller water washing roller of the upper/lower guide roller water washing roller set is placed below the liquid level of the lower hydraulic fluid tank, and the upper line guide roller water washing roller of the upper/lower guide roller water washing roller set is above. It is placed above the liquid level of the lower hydraulic fluid tank, and a fourth set of water spray pipes for spraying and washing the front surface of the fabric are installed at the upper part thereof.

The technical solutions to which this invention is further limited include the following.

The third set of water spray pipes includes two or more water pipes that simultaneously clean the front of the fabric wrapped on the front and rear sides of the upper line second drum drive mechanism.

This design not only has the water washing element 1) of the upper and lower guide roller water washing unit designed by traditional technology in a way to improve the water washing effect, but also drives a large drum and washes both the front and back sides of the fabric. A powerful sprinkler device that can be used to This design satisfies the implementation conditions of realizing the effect of removing dirt from the fabric by powerfully washing the surface of the fabric using high-pressure water, which is presented in Paragraph 2.1 among the water washing elements, and this is achieved by using water from the upper and lower guide rollers according to the prior art. It is in no way comparable to a washing unit and further improves the water washing ability of the newly designed water washing unit.

Hereinafter, the structure of the present invention will be further explained by combining the drawings and preferred specific embodiments of the present invention.

As shown in Figure 2, in the present invention, the spray washing/water washing unit in which the drum and guide roller are simultaneously arranged includes a case body, and an upper hydraulic fluid tank and a lower hydraulic fluid tank are installed inside the case body. and; The inside of the case body includes a fabric introduction roller (2), a first roller (3), an upper line first drum driving mechanism (4), and a lower line first drum driving mechanism (5) in order along the fabric (1) transmission path. , an upper line second drum driving mechanism (6), an upper/lower guide roller water washing roller set (7), and a padder mechanism (8) are installed.

The first roller (3) is installed in the upper hydraulic fluid tank and placed at a position below the upper fluid level L1 of the upper hydraulic fluid tank; Compared to the upper/lower guide roller water washing unit designed by traditional technology, the fabric (1) with a fabric holding capacity of 16 meters and a moisture content/moisture content of 8% is still moved to the upper part of the upper hydraulic fluid tank under the action of the first roller (3). It enters below the liquid level L1 and begins to suck the liquid, and when the fabric leaves the upper liquid level L1 and reaches about 1/3 of the circumference of the upper line first drum drive mechanism 4, the liquid suction length is x = 1.99. reaches meters.

The upper line first drum driving mechanism (4) is installed above the upper liquid level L1 of the upper hydraulic fluid tank, and the fabric (1) wrapped around the first drum driving mechanism (4) is located above the first drum driving mechanism (4). A first set of water spray pipes (9) are installed to perform water spray cleaning on the front of the . Under the water spray action of the first set of water pipes 9, the fabric 1 is washed on the front side and meets the conditions for implementing the water wash element 2), so that it officially enters the water washing process.

A portion of the lower line first drum driving mechanism 5 is placed below the lower liquid level L2 of the lower hydraulic fluid tank, and a portion of the lower line first drum driving mechanism 5 is wrapped around the lower line first drum driving mechanism on the front side of the lower line first drum driving mechanism 5. A second set of water pipes (10) are installed to perform water cleaning on the back side of the jean fabric; The second set of water spray pipes (10) includes two or more water spray pipes that are installed in parallel and perform water spray cleaning on the back side of the fabric wrapped around the lower line first drum drive mechanism (5). The fabric 1 can be washed simultaneously with the back side of the fabric 1 under the watering action of the second set of water spray pipes 10, and then under the driving of the lower line first drum driving mechanism 5, the fabric ( 1) leaves the lower liquid level L2 of the lower hydraulic fluid tank and performs paragraph 2.3 of water washing element 2).

The upper line second drum driving mechanism (6) is located above the lower liquid level L2 of the lower hydraulic fluid tank, and its side side has a third set of spray pipes (11) for spraying and washing the front of the fabric (1). is installed; In order to achieve a better spray cleaning effect, the third set of spray pipes 11 is equipped with two or more spray pipes that simultaneously perform spray cleaning on the front side of the fabric wrapped by the front and rear sides of the upper line second drum drive mechanism 6. Pipes are included. In the drawing of this embodiment, one water spray pipe is disposed in front of the upper line second drum driving mechanism 6, and two water water pipes are disposed behind the upper line second drum driving mechanism 6 to form a front surface of the fabric. The effect of proceeding with water washing again can be achieved.

The lower line guide roller water washing roller of the upper/lower guide roller water washing roller set (7) is placed below the lower liquid level L2 of the lower hydraulic fluid tank, and the upper/lower guide roller water washing roller set (7) The line guide roller water washing roller is placed above the lower liquid level L2 of the lower hydraulic fluid tank, and a fourth set of water spray pipes 12 are installed on the upper part to perform water spray cleaning on the front of the fabric. The fabric enters the water washing portion of the upper/lower guide roller water washing roller set (7), and water flows from top to bottom on the fabric surface. As shown in FIG. 2, the upper/lower guide roller water washing roller set 7 includes a first upper guide roller (S1), a first lower guide roller (R1), a second upper guide roller (S2), and a second upper guide roller (S1). It includes a lower guide roller (R2), a third upper guide roller (S3), a third lower guide roller (R3) and a fourth upper guide roller (S4); The fourth set of water spray pipes 12 includes two water spray pipes that perform water spray cleaning on the front surfaces of the fabric of the second upper guide roller S2 and the third upper guide roller S3, respectively.

When the fabric is moved to the first upper guide roller (S1), the radial tension of the first upper guide roller (S1) is applied to the surface of the fabric wrapped around the first upper guide roller (S1), causing the water washing element 3) will be implemented; The moisture inside the fabric and between the fibers is released from the fiber surface, and water exchange occurs between clear water and the water washing element 1), and impurities are discharged from the fabric through water exchange. When the fabric has moved to the second upper guide roller S2 and the third upper guide roller S3, in addition to meeting the conditions of water washing element 3) and water washing element 1), the action of the fourth set of water spray pipes 12 Under this, the front side of the fabric is sprayed and washed again. Compared to the upper/lower guide roller water washing unit according to the prior art, the present design further improves the water washing effect. Following the fourth upper guide roller S4, the fabric enters the padding mechanism 8 shown in Fig. 2, and its water content and moisture content reach 70%.

The upper and lower guide roller water washing roller set (7) of the present invention optimizes the water washing element 2) conditions by moving the fabric from the upper guide roller to the downward fabric movement path of the lower guide roller; By spraying water from the water pipe toward the surface of the fabric while moving down, paths that are not originally “effective water washing length” such as W2, W3, and W4 are optimized to “effective water washing length”, and W2 is the first upper guide roller. It refers to the length of the fabric from leaving (S1) to reaching the lower liquid level (L2) of the lower hydraulic fluid tank, and W3 refers to the length of the fabric from leaving the second upper guide roller (S2) to the lower part of the lower hydraulic fluid tank. Indicates the fabric length from reaching the liquid level (L2), and W4 refers to the fabric length from leaving the third upper guide roller (S3) to reaching the lower liquid level (L2) of the lower hydraulic fluid tank. . Therefore, the “effective water washing length” of the present invention reaches Z=(U1+U2+U3+U4+W1+W2+V1+W3+V2+W4+V3)=11.75 meters; Here, U1 refers to the fabric length from the upper line first drum drive mechanism 4 to the lower line first drum drive mechanism 5; U2 is wrapped around the front side of the lower line first drum drive mechanism 5, and indicates the length of the fabric before entering the lower liquid level L2 of the lower hydraulic fluid tank; U3 indicates the fabric length from leaving the lower liquid level (L2) of the lower hydraulic fluid tank to reaching the upper line second drum drive mechanism (6); U4 indicates the length of the fabric when wrapped around the upper line second drum drive mechanism 6; W1 refers to the fabric length from the upper line second drum drive mechanism (6) to the first upper guide roller (S1); V1 indicates the fabric length from leaving the lower liquid level (L2) of the lower hydraulic fluid tank to reaching the second upper guide roller (S2); V2 indicates the fabric length from leaving the lower liquid level (L2) of the lower hydraulic fluid tank to reaching the third upper guide roller (S3); V3 indicates the length of the fabric from leaving the lower liquid level (L2) of the lower hydraulic fluid tank to reaching the fourth upper guide roller (S4). Therefore, inside the spray washing/water washing unit where the drum and guide rollers are arranged simultaneously and the fabric holding capacity is 16 meters, there are two “effective water washing units” of the prior art upper/lower guide roller water washing unit with the same fabric holding capacity of 16 meters. length” was exceeded by a very large measure.

When contrasting the present design with the water washing element 2) of the upper/lower guide roller water washing unit designed by the prior art, the present design can realize the water washing effect of decontamination on the fabric through the relative movement between water and the fabric. There is; First, taking advantage of the large deployment area of the driven large drum and the large area around which the fabric is wrapped, powerful washing is performed on both the front and back sides of the fabric by placing one or multiple watering pipes on the driven large drum. proceeding; Second, when water washing is carried out with the upper and lower guide rollers, water flows from top to bottom on the fabric surface; The fabric holding capacity is the same at 16 meters, and the “effective water washing length” reaches 11.75 meters.

When contrasting this design with the pressing, which is the water washing element 3) of the upper and lower guide roller water washing unit designed by the prior art, a technical solution is realized that allows the fabric contamination removal effect to be applied to the traditional design through mechanical action force, Based on the above conclusion obtained “in comparison with the water washing element 2) of the upper and lower guide roller water washing unit designed by the prior art”, assuming that the “effective water washing length” of the water washing unit is the same, the present invention reduced one set of padders when designing the water wash element 3). However, in one aspect of the present invention, a first set of sprinkler pipes (9) are disposed behind the upper line first drum driving mechanism (4), and a second set of water pipes (9) are disposed in front of the lower line first drum driving mechanism (5). A water spray pipe (10) is disposed, a third set of water spray pipes (11) are disposed in the upper line second drum driving mechanism (6), and a fourth set of water spray pipes are disposed in the upper and lower guide roller water washing roller sets (7). By designing (12) to install a total of 8 water spray pipes, the washing role for both the front and back sides of the fabric is realized, and the implementation effect of water washing element 2.3) is greatly improved. In another aspect, the “effective water washing length” after optimization is also 2.16 times the sum of the two upper and lower guide roller water washing units designed by traditional technology. These two additional arrangements can improve the efficiency of discharging the impurities inside the fabric and between the fibers to the fabric surface and exchanging water with clear water and the water washing element 1), and the overall efficacy is reduced by one set. Replaces the fader of

As shown in Figure 3, when the upper/lower guide roller water washing unit according to traditional technology is located in the first tank behind the steaming tank during continuous dyeing, at this time, the fabric is moved to the upper/lower guide rollers. The water content/moisture content entering the front of the water washing unit is approximately 100%, and after receiving the fabric, it begins to suck liquid through the lower line guide roller (R1), and the fabric leaves the lower line guide roller (R1). When leaving the water surface, the water content/moisture content is already set forth in Article 2.3 of Water Washing Factor 2), “When the upper/lower guide rollers perform water washing, water flows from top to bottom on the fabric surface to achieve effective water washing. The “Iru” implementation condition can be satisfied, and at this time, the fabric starts water washing for the first time in this water washing unit. Then, when the fabric is moved to the upper line roller S1, the radial tension of the roller is applied to the surface of the fabric wrapped around the roller, causing the water washing element 3) to be implemented; The moisture inside the fabric and between the fibers is released from the fiber surface, water exchange occurs between clear water and the water washing element 1), and impurities are discharged from the fabric through water exchange. In an abnormal situation, the lower line guide roller (R1) It continues all the way from the rear to the lower line guide roller (r6). Then, it enters the first padder shown in Fig. 3 at the rear of the continuous dyeing steaming tank, and after being pressed, its moisture content/moisture content is usually about 70%.

The above statement interprets the reason that the “effective water washing length” inside the first upper/lower guide roller water washing unit shown in Figure 3 is v1+v2+v3+v4+v5+v6=5.02 meters; Here, v1, v2, v3, v4, v5 and v6 respectively indicate the length of the fabric from leaving the liquid surface L to reaching the 6-row roller. Before the fabric leaves the first upper/lower guide roller water washing unit shown in Figure 3 at the rear of the steaming tank of continuous dyeing, the fabric passes through the first padder shown in Figure 3, and then the moisture content of the fabric /The water content reaches 70% and prepares in advance for the next step of the water washing process.

The water washing element 2) inside the upper and lower guide roller water washing unit designed by the prior art mainly causes water to flow from top to bottom on the fabric surface when the fabric moves in and out of the upper and lower guide rollers; Likewise, taking Figure 3 as an example, after the fabric enters and exits the steaming tank of continuous dyeing, the water washing element inside the second upper and lower guide roller water washing unit 2) The horizontal yarn direction of the fabric conforms to the key. The length is 4.09 meters.

When a fabric with an initial water content/moisture content of 70% enters the second upper/lower guide roller water washing unit at the rear of the continuous dyeing steaming tank, the fabric must first enter the liquid level L and be washed by the lower line guide roller below the liquid level. (r7) and should begin to suck liquid, and when the fabric leaves the lower line guide roller (r7) and leaves the water surface, its moisture content/moisture content can fundamentally satisfy the implementation of water washing factor 2). There is no, and even if the upper guide roller (s6) is separated, the implementation conditions of water washing element 3) are still not satisfied, so the fabric must re-enter the liquid level L and contact the lower line guide roller (r8) below the liquid level. The liquid must be sucked in again, and only when the fabric leaves the lower line guide roller (r8) and leaves the water surface is the moisture content/moisture content set forth in Article 2.3 of Water Washing Factor 2), “The upper/lower guide rollers are When washing, water flows from top to bottom on the fabric surface to achieve effective water washing” can be satisfied, and only at this time can water be applied to the second upper and lower guide rollers shown in Figure 3 at the rear of the steaming tank of continuous dyeing. Among the washing units, it is the first to start water washing. Then, when the fabric is moved to the upper line roller s7, the radial tension of the roller is applied to the surface of the fabric wrapped around the roller, causing water washing element 3) to be implemented; The moisture inside the fabric and between the fibers is expelled from the fiber surface, water is exchanged between clear water and the water washing element 1), and impurities are discharged from the fabric through water exchange. In an abnormal situation, the lower line guide roller (r7) It continues all the way from the rear to the lower line guide roller r12, and then enters the second padder at the rear of the continuous dyeing steam tank, and its moisture content/moisture content is usually about 70%.

The above statement interpreted the reason why the “effective water washing length” inside the second upper/lower guide roller water washing unit shown in FIG. 3 is v8+v9+v10+v11+v12=4.09 meters. Here, v8, v9, v10 and v11 reach the upper line roller (s7), upper line roller (s8), upper line roller (s9) and upper line roller (s10) from the point where the fabric leaves the liquid surface L, respectively. V12 refers to the length of the fabric from leaving the liquid level L to reaching the second feather. Before the fabric leaves the second upper/lower guide roller water washing unit at the rear of the continuous dyeing steaming tank, the fabric passes through the second padder, and then the water content/moisture content of the fabric is restored to about 70%. , prepare in advance for the next step of the water washing process. When these two identical water wash units are connected together, the total “effective water wash length” is v1+v2+v3+v4+v5+v6+v8+v9+v10+v11+v12=9.11 meters.

The compression of the water washing element 3) of the upper and lower guide roller water washing unit designed using traditional technology realizes the water washing effect of dirt removal through mechanical action force. The fabrics are water washed inside each water wash unit and then pressed before being transferred to the next water wash unit. Typically, the pressing method of the upper/lower guide roller water washing unit according to traditional technology is mainly realized through two paths: first, through a padder, but sometimes, based on process demands, a method such as squeezing water in a vacuum is performed; using other methods; Second, when water washing is performed using the upper and lower guide rollers inside the upper and lower guide roller water washing unit according to the prior art, compression is performed through the pressure point between the fabric and the guide rollers.

As shown in Figure 4, in the present invention, the spray washing/water washing unit disposed when the drum and guide roller are in operation is placed at the rear of the steaming tank during continuous dyeing, and the initial moisture content/moisture content of the fabric is about 100%. case, its “effective water washing length” already reaches 13.09 meters. The difference from Figure 2 is that the fabric holding capacity is still 16 meters, and the fabric with the initial moisture content/moisture content of 100% enters below the upper liquid level (L1) of the upper hydraulic fluid tank and begins to suck liquid, and the fabric enters the upper hydraulic fluid tank. When leaving the upper liquid level (L1), the required liquid suction length x = 0.44 meters is already reached. In other words, as shown in Figure 4, its “effective water washing length” is “Z=(V1'+U1+U2+U3+U4+W1+W2+V2'+W3+V3'+W4+V4' ) = 13.09 meters, and when compared with Figure 2, the difference is that V1' is the fabric from leaving the upper liquid level (L1) of the upper hydraulic fluid tank to leaving the upper line first drum drive mechanism (4). V2' refers to the length of the fabric from leaving the lower liquid level (L2) of the hydraulic fluid tank to reaching the second upper guide roller (S2), and V3' refers to the lower liquid level of the hydraulic fluid tank ( V4' refers to the length of the fabric from leaving the lower liquid level (L2) of the hydraulic fluid tank to reaching the third upper guide roller (S3). ) refers to the length of fabric that reaches . Therefore, inside a spray washing/water washing unit where the drum and guide rollers are arranged simultaneously and the fabric holding capacity is 16 meters, two of them are the “effective water washing length” of a conventional upper/lower guide roller water washing unit with the same fabric holding capacity of 16 meters. ” was greatly exceeded.

In order to reduce the volume of the present invention and shorten the equipment length, the lower line first drum driving mechanism 5 is partially placed below the upper line first drum driving mechanism 4, and the upper line second drum driving mechanism (6) is partially placed above the lower line first drum driving mechanism (5), and the water washing roller of some guide rollers of the upper/lower guide roller water washing roller set (7) is placed above the upper line second drum driving mechanism. It is placed below (6).

“Clear water” as used in this patent refers to soft water, that is, the content of magnesium/calcium carbonate per liter of water is less than 6 hardness, and 1 hardness corresponds to containing 10 milligrams of magnesium/calcium carbonate per liter of water. It is usually expressed as ppm, which is milligram of magnesium carbonate per liter of water. The “rear” written refers to the exit side of the fabric. The “front” written refers to the fabric entry side.
