:表示經烘乾後的織物品 質；G:表示完全乾燥的織物品質；由於織物材料的不同，吸水性不同也會導致其含水率/含水量不同。以此為切入點，我們便可以開始分析影響水洗效果的具體要素。 At present, there are many cleaning and cleaning methods for washing equipment on the market, apart from the method that does not use water. As a washing unit equipped with a drum rotor mechanism and a guide roller at the same time, the primary condition for its washing must be "water". Effective water laundering is not achieved when the fabric has insufficient moisture/moisture content without being adequately soaked. The moisture content referred to is based on the calculation method of moisture content given by QB/T2330-2017 "Industrial Dryer":

=

;

: Indicates the quality of the fabric after drying; G: Indicates the quality of the completely dried fabric; Due to different fabric materials, different water absorption will also lead to different moisture content/water content. With this as a starting point, we can start to analyze the specific elements that affect the effect of washing.

Five elements that affect the washing effect:

1). The washing effect of the fabric is achieved through the exchange of water/water; such as adding water/rehydration, the mutual flow/exchange of clean water and dirty water; impurities are discharged from the fabric through water exchange; the clean water refers to soft water, that is, The magnesium carbonate/calcium content per liter of water is less than 6 hardness, and 1 hardness is equivalent to 10 mg of magnesium carbonate/calcium per liter of water, usually expressed in ppm as mg magnesium carbonate/liter of water.

2). Through the relative movement between the water and the fabric to achieve the washing effect of fabric decontamination; specifically including:

2.1. Use high-pressure spray to scour the surface of the fabric;

2.2. The strong penetration of the fabric by the eddy current formed by the forced convection generated by the relative motion of the rotor/drum;

2.3. The water flows from top to bottom on the fabric surface when the upper/lower guide rollers are washed.

3). Squeeze; that is, to achieve decontamination washing effect through mechanical force. For example, the squeezing of the fabric by the rollers of the rolling car, the squeezing effect between the fabric and the guide rollers due to tension when the upper/lower guide rollers are washed, the dirty water in the fibers and between the fibers is forced out of the fiber surface, and The water exchange of the washing element 1) is carried out with clean water, and the impurities are discharged from the fabric through the water exchange.

The washing element 3) of the traditionally designed upper/lower guide roller washing unit is to achieve the decontamination washing effect through mechanical force. The fabrics are squeezed after being washed in each washing unit before being transferred to the next washing unit. Generally, the extrusion method of the traditional upper/lower guide roller water washing unit is mainly realized in two ways: one is through the rolling car (but sometimes other methods such as vacuum pressing are also used according to the needs of the process); the second is through the traditional When the upper/lower guide roller in the washing unit of the lower guide roller is washed, the pressure point between the fabric and the guide roller is squeezed.

4). Chemical auxiliaries; use chemical reactions to improve washing efficiency; another purpose is to provide chemical reactions required for fabrics such as: mercerizing, bleaching, etc.

5). Temperature; temperature helps to increase the thermal energy during washing. With the increase of temperature, it can accelerate the dissolution of auxiliaries or detergents, and its active molecules move faster and can penetrate the fabric quickly, and the decontamination ability is stronger. Improve water washing efficiency; another purpose is to provide the reaction temperature required for chemical additives; such as: steaming.

In addition, the washing program will also affect its washing effect. For example, "desizing, scouring, reductive soaping" and other processes can choose different washing programs for different fabric types, stain characteristics, and soiling levels to achieve the ideal washing effect.

The washing element 2) in the traditionally designed upper/lower guide roller washing unit is mainly the flow of water from top to bottom on the fabric surface when the fabric is shuttled between the upper/lower guide rollers; take Figure 1 as an example; The warp length of the fabric in the washing unit of the lower guide roller and conforming to this washing factor 2) is 4.09 meters.

Taking Figure 1 as an example, although the fabric capacity in the traditionally designed upper/lower guide roller washing unit is 16 meters, in the actual production scenario, the fabric is washed in the first upper/lower guide roller in the front section of the long car. The front of the unit is generally from the previous process, such as: singeing, desizing treatment process, and the moisture content/moisture content of the circulating dry cloth is generally about 8%. When the upper/lower guide rollers in the front section of the car do not wash the unit, the fabric must first enter the liquid level L and contact the lower guide roller r1 under the liquid to start to absorb liquid, and when the fabric leaves the lower guide roller r1 and leaves the water surface, Its moisture content/water content cannot satisfy the implementation of the water washing factor 2) at all, and it also cannot satisfy the implementation of the water washing factor 3) when the upper guide roller s1 is applied, so the fabric must enter the liquid level L again and contact the liquid under the liquid. The lower guide roller r2 absorbs the liquid again. When the fabric leaves the lower guide roller r2 and leaves the water surface, its moisture content/water content can meet the requirements of item 2.3 in the washing factor 2) "When the upper/lower guide roller is washed with water. The conditions for the implementation of "effective washing" with the flow of water on the surface of the fabric from top to bottom, is the first time to start washing in this washing unit. After that, when the fabric runs to the upper row of rollers s5, the surface of the fabric covering the roller is subjected to the radial tension of the roller, which promotes the implementation of the washing element 3). , and exchange with clean water for the water washing element 1), the impurities are discharged from the fabric through water exchange, and the above situation continues from the lower row of guide rollers r5 to the lower row of guide rollers r6. Next, enter the first rolling car in the front section of the long car, and its moisture content/water content is generally about 70%.

The above statement explains why the "effective washing length" in the first upper/lower guide roller washing unit in Figure 1 is equal to v5+v6=1.34 meters. Before the fabric leaves the first upper/lower guide roller washing unit in the front section of the long car, the fabric will pass through the first paddle, after which the fabric moisture/water content reaches 70%, in preparation for the next washing process.

The water washing element 2) in the traditionally designed upper/lower guide roller washing unit is mainly the flow of water on the fabric surface from top to bottom when the fabric is shuttled between the upper and lower guide rollers; also take Figure 1 as an example; the fabric shuttles on a long car The warp length of the fabric in the second upper/lower guide roller washing unit shown in Figure 1 in the preceding paragraph and conforming to this washing factor 2) is 4.09 meters.

When the fabric with moisture content/water content of 70% enters the second upper/lower guide roller unit shown in Figure 1 in the front section of the long car, the fabric must first enter the liquid level L and contact the lower row guide roller r7 under the liquid And start to absorb liquid, and when the fabric leaves the lower guide roller r7 and leaves the water surface, its moisture content/water content is not satisfied with the implementation of the water washing factor 2), and the upper guide roller s6 is not satisfied with the water washing. The implementation of element 3), so the fabric must enter the liquid level L again and contact the lower guide roller r8 under the liquid to absorb the liquid again. When the fabric leaves r8 and leaves the water surface, its moisture content/water content can meet the washing factor. 2) The conditions for the implementation of item 2.3 "Effective washing with water flowing from top to bottom on the surface of the fabric when washing the upper/lower guide rollers", this is the second washing unit in Figure 1 in the front section of the long car Started washing for the first time. After that, when the fabric runs to the upper row of rollers s7, the surface of the fabric covering the roller is subjected to the radial tension of the roller, which promotes the implementation of the water washing element 3); the fibers in the fabric and the moisture between the fibers are expelled from the surface of the fibers , and carry out water exchange of washing element 1) with clean water, impurities are discharged from the fabric through water exchange, and the above situation continues from the lower guide roller r7 to r12. Next, enter the second rolling car in Figure 1 in the front section of the long car, and its moisture content/water content generally reaches 70%.

The above statement explains why the "effective washing length" in the second upper/lower guide roller washing unit shown in Figure 1 is equal to v8+v9+v10+v11+v12=4.09 meters. Before the fabric leaves the upper/lower guide roller washing unit, the fabric will pass through the second paddle shown in Figure 1, after which the fabric moisture/moisture content will return to about 70% in preparation for the next washing process. In this way, when two identical washing units are connected together, their "effective washing length" totals v5+v6+v8+v9+v10+v11+v12=5.43 meters.

To sum up, the overall water washing efficiency of the existing water washing unit is low, the number of water washing units of the entire open-width wet treatment equipment is long, and the entire open-width wet treatment equipment occupies a large area.

The first roller 3 is set in the upper working liquid tank, and is placed below the upper liquid level L1 of the upper working liquid tank; compared with the traditionally designed upper/lower guide roller washing unit, it is also 16 meters long. The fabric 1 with cloth capacity, moisture content/water content of 8%, under the action of the first roller 3, enters the upper liquid level L1 of the upper working liquid tank and starts to absorb liquid. When the fabric leaves the upper liquid level L1, it reaches the upper liquid level L1. The suction length of x=1.99 meters has been reached when the first drum driving mechanism 4 is arranged at about 1/3 of the circumference.

Rinse spray pipe. Under the spraying action of the second group of spray pipes 10, the reverse side of the fabric 1 is also washed at the same time, and then driven by the first drum driving mechanism 5 in the lower row, the fabric 1 leaves the lower liquid surface of the lower working liquid tank. L2, perform item 2.3 of water washing element 2).

The upper row of the second drum driving mechanism 6 is located above the lower liquid level L2 of the lower working liquid tank, and its side is provided with a third group of spray pipes 11 for spraying and washing the front of the fabric 1; For the effect of spraying and washing, the third group of spraying pipes 11 includes two or more spraying pipes for spraying and washing the front side of the fabric covered by the front side and the rear side of the second drum driving mechanism 6 in the upper row at the same time. In the drawings of this embodiment, a spray pipe is arranged in front of the second drum driving mechanism 6 in the upper row, and two spray pipes are arranged behind the second drum driving mechanism 6 in the upper row. The effect of spray washing again on the front.

The lower row of guide rollers of the upper/lower guide roller washing roller group 7 is placed below the lower liquid level L2 of the lower working liquid tank, and the upper row of the upper/lower guide rollers washing roller group 7 The roller washing roller is placed above the lower liquid level L2 of the lower working liquid tank, and is provided with a fourth group of spray pipes 12 for spraying and washing the front surface of the fabric. The fabric enters the washing part of the upper/lower guide roller washing roller group 7, and the water flows from top to bottom on the surface of the fabric. In FIG. 2, the upper/lower guide roller washing roller group 7 includes a first upper guide roller S1, a first lower guide roller R1, a second upper guide roller S2, a second lower guide roller R2, and a third upper guide roller S3, the third lower guide roller R3 and the fourth upper guide roller S4; the fourth group of spray pipes 12 includes two spray pipes for spraying and washing the front surface of the fabric on the second upper guide roller S2 and the third upper guide roller S3 respectively. root spray pipe.

When the fabric runs to the first upper guide roller S1, the surface of the fabric wrapped on the first upper guide roller S1 is subjected to the radial tension of the first upper guide roller S1, which promotes the implementation of the washing element 3); the fibers and fibers inside the fabric The moisture between the fibers is expelled from the surface of the fiber, and is exchanged with clean water for the water washing element 1), and the impurities are discharged from the fabric through the water exchange. When the fabric runs to the second upper guide roller S2 and the third upper guide roller S3, in addition to the conditions for continuing to perform the water washing element 3) and the water washing element 1), under the action of the fourth group of spray pipes 12, the fabric is treated again. The front of the spray wash. Compared with the traditional upper/lower guide roller washing unit, the new model further improves the washing effect. Following the fourth upper guide roll S4, the fabric 1 enters the rolling mechanism 8 as shown in FIG. 2 from the fifth upper guide roll S5, and its moisture content reaches 70%.

The new type of upper/lower guide roller washing roller set 7 also optimizes the downward walking path of the fabric from the upper guide roller to the lower guide roller to achieve the conditions for the water washing element 2); let the water be sprayed downward from the spray pipe For the fabric surface in the middle, the original paths that are not "effective washing length", such as W2, W3, W4, are also optimized to "effective washing length". W2 refers to leaving the first upper guide roller S1 to the lower liquid surface of the lower working liquid tank. The fabric length between L2, W3 refers to the fabric length from the second upper guide roller S2 to the lower liquid level L2 of the lower working liquid tank, W4 refers to the distance from the third upper guide roller S3 to the lower surface of the lower working liquid tank Fabric length between liquid level L2. Thus, the new "effective washing length" Z=(U1+U2+U3+U4+W1+W2+V1+W3+V2+W4+V3)=11.75 meters; wherein, U1 is the first drum drive in the upper row The length of the fabric between the mechanism 4 and the first drum driving mechanism 5 in the lower row; U2 is the length of the fabric covering the front side of the first drum driving mechanism 5 in the lower row before entering the lower liquid level L2 of the lower working liquid tank; U3 In order to leave the lower liquid level L2 of the lower working liquid tank to the upper row of the second drum drive mechanism 6, the length of the fabric; U4 is the length of the fabric wrapped on the upper row of the second drum drive mechanism 6; W1 is the upper row The length of the fabric from the second drum drive mechanism 6 to the first upper guide roller S1; V1 is the length of the fabric from the lower liquid level L2 of the lower working liquid tank to the second upper guide roller S2; V2 is the length of the fabric from the lower working liquid tank The fabric length from the lower liquid level L2 of the liquid tank to the third upper guide roller S3; V3 is the fabric length from the lower liquid level L2 of the lower working liquid tank to the fourth upper guide roller S4. Therefore, in this 16-meter spray/water washing unit equipped with both drum and guide roller, the "effectiveness" of the two traditional upper/lower guide roller washing units with the same 16-meter cloth capacity has been greatly exceeded. Washed Length".

Compared with the traditional design of the upper/lower guide roller washing unit, the new model achieves the washing effect of fabric decontamination through the relative movement between the water and the fabric. The fabric has a large coverage area, and the front and back sides of the fabric are strongly washed by configuring a single or multiple spray pipes for the driving drum; The surface flows from top to bottom; the same cloth capacity is 16 meters, and the "effective washing length" reaches 11.75 meters.

This new type compares the traditional design of the upper/lower guide roller washing unit washing elements 3) Squeeze: the application of mechanical force to achieve the effect of fabric decontamination in the traditional design, according to the above "Comparing the traditional design of the upper/lower guide roller The conclusion drawn from the washing element 2) of the washing unit, assuming that the "effective washing length" of the washing unit is the same, the design of the washing element 3) of the new model is one less rolling car. However, in the present invention, on the one hand, a first group of spray pipes 9 are arranged behind the first drum driving mechanism 4 in the upper row, and a second group of spray pipes 10 are respectively arranged in front of the first drum driving mechanism 5 in the lower row. The drum drive mechanism 6 is equipped with a third group of spray pipes 11, and the upper/lower guide roller washing roller group 7 is equipped with a fourth group of spray pipes 12. The design of a total of 8 spray pipes ensures that the front and back sides of the fabric can be sprayed. The double-sided rinsing effect greatly improves the implementation effect of item 2.3) of the water-washing element. On the other hand, its optimized "effective washing length" is also equal to 2.16 times the sum of the two upper/lower guide roller washing units of the traditional design. These two additional configurations improve the water exchange efficiency of the fibers inside the fabric and the dirt between the fibers being discharged to the surface of the fabric and with clean water as a water washing element 1), and the combined effect replaces the missing set of paddles.

Referring to Figure 3, when the traditional upper/lower guide roller washing unit is placed in the first box after the steaming box in the long car, the moisture content/water content of the fabric before entering the upper/lower guide roller washing unit at this time About 100%, after the fabric enters the water, it starts to absorb liquid through the lower guide roller r1, and when the fabric leaves the lower guide roller r1 and leaves the water surface, its moisture content/water content can already meet the requirements of 2.3 in the water washing factor 2). The conditions for the implementation of the item "effective washing with water flowing from top to bottom on the surface of the fabric during the washing of the upper/lower guide rollers", at this time, the fabric starts to be washed for the first time in this washing unit. After that, when the fabric runs to the upper row of rollers s1, the surface of the fabric wrapped around the roller is acted by the radial tension of the roller, which promotes the implementation of the washing element 3); the fibers in the fabric and the moisture between the fibers are expelled from the surface of the fibers , and exchange with clean water for the water washing element 1), and the impurities are discharged from the fabric through water exchange. The above situation continues from the lower guide roller r1 to the lower guide roller r6. After entering the steam box of the long car, the first rolling car shown in Figure 3, the moisture content/water content after rolling is generally about 70%.

The above statement explains why its "effective washing length" in the first upper/lower guide roller washing unit shown in Figure 3 is equal to v1+v2+v3+v4+v5+v6=5.02 meters; where v1, v2, v3 , v4, v5 and v6 respectively refer to the length of the fabric when the fabric leaves the liquid level L and reaches the length of the 6 row rollers. When the fabric leaves the steaming of the long car, the first upper/lower guide roller washing unit shown in Figure 3 Before, the fabric will go through the first paddle shown in Figure 3, after which the fabric moisture content/water content reaches 70%, in preparation for the next washing process.

The water washing element 2) in the traditionally designed upper/lower guide roller washing unit is mainly the flow of water on the fabric surface from top to bottom when the fabric is shuttled between the upper and lower guide rollers; also take Figure 3 as an example; the fabric shuttles on a long car After the steam box, the warp length of the fabric in the second upper/lower guide roller washing unit and conforming to this washing factor 2) is 4.09 meters.

When the fabric with an initial moisture content/water content of 70% enters the second upper/lower guide roller washing unit after the steaming box of the long car, the fabric must first enter the liquid level L and contact the lower guide roller r7 under the liquid And start to absorb liquid, and when the fabric leaves the lower guide roller r7 and leaves the water surface, its moisture content/water content is not satisfied with the implementation of the water washing factor 2) at all, and it is also not satisfied when the upper guide roller s6 is discharged. The implementation of the water washing factor 3), the fabric must enter the liquid level L again and contact the lower guide roller r8 under the liquid to absorb the liquid again. When the fabric leaves the lower guide roller r8 and leaves the water surface, its moisture content/water content can be To meet the conditions for the implementation of item 2.3 "effective washing with water flowing on the fabric surface from top to bottom during washing with the upper/lower guide rollers" in the washing elements 2), this is the time for the steam box of the long car Afterwards, as shown in Figure 3, the first water washing is started in the second upper/lower guide roller washing unit. After that, when the fabric runs to the upper row of rollers s7, the surface of the fabric covering the roller is subjected to the radial tension of the roller, which promotes the implementation of the water washing element 3); the fibers in the fabric and the moisture between the fibers are expelled from the surface of the fibers , and carry out water exchange with clean water for washing element 1), impurities are discharged from the fabric through water exchange, the above scenario continues from the lower row guide roller r7 to the lower row guide roller r12, and then enters the steam box of the long car After the second rolling car, its moisture content/water content generally reaches 70%.

The above statement explains why the "effective washing length" in the second upper/lower guide roller washing unit shown in Figure 3 is equal to v8+v9+v10+v11+v12=4.09 meters, where v8, v9, v10 and v11 refers to the length of the fabric from the liquid level L to the upper row of rollers s7, upper row of rollers s8, upper row of rollers s9 and upper row of rollers s10 respectively, v12 refers to the fabric from the liquid level L to the second rolling workshop. fabric length. Before the fabric leaves the second upper/lower guide roller washing unit after the long car steam box, the fabric will pass through the second paddle, after which the fabric moisture/moisture content will return to about 70% for the next step. Prepare for the washing process. In this way, when two identical washing units are connected together, their "effective washing length" amounts to v1+v2+v3+v4+v5+v6+v8+v9+v10+v11+v12=9.11 meters.

The washing elements of the traditionally designed upper/lower guide roller washing unit 3) Squeeze; through mechanical force to achieve decontamination washing effect. The fabrics are squeezed after being washed in each washing unit before being transferred to the next washing unit. Generally, the extrusion method of the traditional upper/lower guide roller water washing unit is mainly realized in two ways: one is through the rolling car, but sometimes other methods such as vacuum squeezing are also used according to the needs of the process; the other is through the traditional / When the upper/lower guide rollers in the lower guide roller washing unit are washed, the pressure point between the fabric and the guide rollers is squeezed.

Referring to Figure 4, when the new spray/water washing unit equipped with both drum and guide roller is placed in the steaming box in the long car, when the initial moisture content/water content of the fabric is about 100%, its " "Effective washing length" has reached 13.09 meters. The difference from Fig. 2 is that the fabric with the same cloth capacity of 16 meters and the initial moisture content/water content of 100% enters the upper liquid level L1 of the upper working liquid tank and starts to absorb liquid. When the fabric leaves the upper working liquid tank When the upper liquid level L1 is reached, the required suction length of x=0.44 meters has been achieved. That is, the "effective washing length" Z=(V1'+U1+U2+U3+U4+W1+W2+V2'+W3+V3'+W4+V4')=13.09 meters in Figure 4, compared to Figure 2, The difference is that V1' refers to the length of the fabric between the upper liquid level L1 leaving the upper working liquid tank and leaving the upper row of the first drum driving mechanism 4, and V2' refers to the lower liquid level L2 leaving the working liquid tank. The fabric length between the two upper guide rollers S2, V3' refers to the fabric length between the lower liquid level L2 leaving the working liquid tank and the third upper guide roller S3, V4' refers to the lower liquid level L2 leaving the working liquid tank The fabric length between the fourth upper guide roller S4 and V5' refers to the fabric length between the fourth upper guide roller S4 and the fifth upper guide roller S5. Therefore, the "effective washing length" of the two traditional upper/lower guide roller washing units with the same capacity of 16 meters has been greatly exceeded in the 16-meter spray washing/water washing unit equipped with both drum and guide roller. .

In order to reduce the volume of the present invention and reduce the length of the equipment, the first drum driving mechanism 5 in the lower row is partially placed under the first drum driving mechanism 4 in the upper row, and the second drum driving mechanism 6 in the upper row is partially placed in the lower row. Above the row of the first drum drive mechanism 5, part of the guide roller washing rollers of the upper/lower guide roller washing roller group 7 are placed below the second drum drive mechanism 6 in the upper row.
