[0039] Embodiment 1
[0040] The warp yarn of the anti-viral tweed is 76 / 2, W44 zinc wire 56, and the warp yarn accounts for 55% of the fabric. The weft yarn is 6 / 2, W44 zinc wire 56, and the weft yarn accounts for 45% of the fabric. The piece dyeing process of this anti-viral tweed includes the following steps:
[0041] A. Warp and weft dyeing: Warp and weft yarns made of W44 zinc wire 56 are prepared, and a set amount of dye, auxiliary agent and clean water are mixed to obtain a primary dye solution. The warp and weft yarns are dyed with the primary dye solution to obtain dyed yarns;
[0042] The dyes in the primary dye solution in step A are 0.714% of Jagersul Deep Red GE, 0.91% of Jagersul Deep Yellow GE, and 0.0214% of Jagersul Dark Blue GE.
[0043] The auxiliary agents in step A are 1 g / P of soda ash, 40 g / P of sodium sulfate, and a bath ratio of 1:20.
[0044] In the step A, the dye solution is added multiple times at set time intervals according to the percentage of the total amount of sodium sulfate when the temperature of the dye solution is 30°C.
[0045] In the step A, sodium sulfate is added three times with intervals of 10 minutes.
[0046] In the step A, 1 / 6 of the total weight of sodium sulphate is added for the first time, 2 / 6 of the total weight of sodium sulphate is added for the second time, and 3 / 6 of the total weight of sodium sulphate is added for the third time.
[0047] After the sodium sulfate is added multiple times in step A, 3 / 10 of the total amount of soda ash is added, and after the temperature of the primary dye solution is raised to 50° C., the primary dye solution is kept warm for 11 minutes before heating the remaining soda ash.
[0048] The dyed yarn prepared in step A is washed with water and then soaped.
[0049] B. Dyeing all wool: The warp yarn is dyed according to the set yarn specifications, and the weft yarn is dyed according to the set weft yarn specifications. After weaving, a piece of cloth is obtained. The piece of cloth is mixed with a set amount of dye, auxiliary agent and clean water to obtain a secondary dye solution. The above piece of cloth is dyed with the secondary dye solution to obtain a finished antiviral tweed fabric.
[0050] The dyes in the secondary dyeing solution in step B are HD: 0.359%, Methylene Blue Yellow 2NW: 0.209%, and HDG: 0.0386%.
[0051] The auxiliary agents of the secondary dyeing solution in step B are FFA 1 g / l, sodium sulfate 6%, SET 1%, HAC 1%, and (NH 4 ) 2 SO 4 4%.
[0052] The temperature of the secondary dye solution in step B is 35°C.
[0053] In this embodiment, the warp density is 458 yarns / 10 cm, and the weft density is 362 yarns / 10 cm. The antiviral active chlorine of the finished fabric is 99.99%.
[0054] like Figure 1 and Figure 2 and Figure 3As shown, the auxiliary agent feeding device for the piece dyeing process of antiviral tweed includes a hopper 1 with a cavity inside and an opening at the upper end, and also includes a base 2, a driving member 3, a conveying screw 4, a discharge barrel 5 and an anti-blocking component. The base 2 is hollow inside and open at the upper end, the upper end of the base 2 is fixedly connected to the lower end of the hopper 1 and the two are communicated, the side of the base 2 has a through discharge port 2a, the discharge barrel 5 is fixedly connected to the outside of the base 2 and the discharge barrel 5 is communicated with the discharge port 2a, the conveying screw 4 is horizontally arranged at the base 2 and the middle part of the conveying screw 4 is located at the bottom of the base 2, the driving member 3 is fixedly connected to the outside of the base 2 and the driving member 3 is fixedly connected to one end of the conveying screw 4, the other end of the conveying screw 4 is penetrated in the discharge barrel 5, and the anti-blocking component is located in the base 2.
[0055] The anti-blocking component includes a motor 6 and a paddle 7. The motor 6 is fixedly connected to the outside of the base 2. The paddle 7 is fixedly connected to the rotating shaft of the motor 6. A sensor 1 7a is provided on one side of the paddle 7, and a sensor 2 7b is provided on the other side of the paddle 7. In the initial state, the sensor 1 7a is opposite to the lower end of the hopper 1, and the sensor 2 7b is opposite to the conveying screw 4.
[0056] The powdered additive is put into the hopper 1, and the additive enters the base 2 along the hopper 1. The driving member 3 is a servo motor, so the driving member 3 can control the conveying screw 4 to rotate accurately for a set number of turns.
[0057] During the rotation of the conveying screw 4 , the additive in the base 2 is brought into the discharging barrel 5 through the discharging port 2 a , and finally the additive is discharged from the discharging barrel 5 .
[0058] Each time the driving member 3 drives the conveying screw 4 to rotate once, the device completes one feeding.
[0059] During the feeding process, the sensor 1 7a and the sensor 2 7b on the paddle 7 are used to detect the flow rate A of the additive at the upper part of the base 2 and the flow rate B of the additive at the lower part of the base 2, respectively. When the value of A is less than the value of B, it means that the device is discharging normally. Once the value of A is equal to the value of B, it means that the additive inside the base 2 is blocked. At this time, the motor 6 drives the paddle 7 to rotate continuously for a set time, and the additive in the base 2 is stirred and fluffy, and then the normal discharging state is restored.
[0060] Of course, the sensor 1 7a and the sensor 2 7b stop sending detection signals during the rotation of the paddle 7. When the material is discharged normally, the paddle 7 returns to the initial position, that is, the sensor 1 7a faces upwards and the sensor 2 7b faces downwards.
