Where A: 162 B: 64 C: 44 D:46 E: 4 320 roots/cycle.

1.2 Difficulties Analysis

The cloth style of this variety is a multi-color variety in yarn-dyed fabrics, and the warp yarns are five colors, which breaks a warp yarn of a conventional billet fabric . The total number of roots is 9 040, and the number of heads is more. After dense, the flower arrangement is complicated and the number of cycles is large.

Difficulties: The comparison of the number of packages of various yarns cannot meet the needs.

Difficulties II: The flower shape is complex and the number of cycles is large. The axes of the pulp and the flowers do not match.

Difficulties 3: batch warping can not be done, sizing gargle flower row efficiency is low.

Difficulties 4: There will be waves in the barricade.

Difficulties 5: The production of sizing hairiness and secondary hairiness.

2, the specific method of operation

2.1 Upper cylinder

Because it is a variety of staple fiber colors, taking into account that it is necessary to arrange the correct shape, but also to facilitate the pulp and non-stick pulp. With five layers of liquid, the yarn is arranged in a flower shape. After the station, the left warp frame, from the top down, on the 2 row, empty 1 row, a total of 6 rows of 2 rows. The right warp beam, from the bottom to the top, 2 rows empty 1 row, a total of 6 rows of 2 rows. Each of the two axes of the flower shape has three cycles, that is, 240 packages.

2.2 warping process

2.2.1 Tension control of each spindle during warping. Using S2 wrapping in a three-column tensioner, measured 12 to 16.

2.2.2 Divide the total number of heads (9040) into 4 axes. The head of each axis is 2260. The number of bobbins per strip is 240, that is, 240 tubs are to be twisted in 10, and the last strand is to be subtracted by 140.

2.2.3 Axial width control. In order to ensure the smoothness of the shaft surface, the shaft width of the machine is 180cm. (Without the screw in the shaft, the shaft is 180cm in diameter.

2.2.4 The choice of fixed size. The width of the weaving shaft has been controlled at 180 cm. The width of each weaving bar must be controlled. The width of the weaving bar must be used. Push down the width of each strand. Calculate the density of the fixed enthalpy and select the fixed enthalpy and penetration number. Then according to the density of the enthalpy, the yarn branch, and the displacement amount.

2.2.5 How to prevent the yarn from being unwound when the weaving shaft is unwinding in the process of pulping:

(1) Soft slopes are included on the taper surface of the warping machine drum to absorb the warp yarn tension. The yarn tension due to the vehicle speed, distance, etc. is uneven. Soft climbing requirements, selection of finer yarns, moderate density of climbing, small displacement of the design, gradual climbing control

(2) Control the strip width of each strand. In accordance with the provisions of the width of the value, enter the computer, the warp yarn between each strand, can not be skeined, can not be off. To ensure the flatness of the shaft surface.

(3) When rewinding the shaft, do not pile or cut edges on both sides of the beam, so that the actual width of the weaving shaft is the same as the width of the reeling machine shaft.

2.2.6 Special operation requirements during warping:

(1) In order to prevent sticking of the pulp during the process, at intervals of 15 meters from each skein, the 5 layers of Arterial Line are evenly distributed at intervals of 20 cm, and the slashed yarns are separated.

(2) At the 35m tail point, evenly divide the 4 layered Artemisia lines, and all five kinds of colored yarns are layered according to the color, so that it can be easily connected by cloth.

2.3 Shaft

According to the total number of warps, the thickness of the yarn, to set the tension of the shaft, to ensure that the warp beam is not loose. The last 3 meters of the shaft was glued with clear glue. The same layer of warp solids was used to facilitate the pulp and the warp yarns were formed into pieces. The tension is consistent and the tension is even during the warp beam process. Arrange evenly and evenly. The unevenness of the shaft surface and the flaws between the skein and the skein and the squeezing are eliminated.

3, the axis of the shelf and sizing process control point

3.1 Upper axis direction: 4 beams are divided into two groups into two slurry tanks, pay attention to the upper axis

The starting point of the flower shape, the starting point must be the same side and the direction is the same to ensure the consistency with the file after the machine.

3.2 Dedicated sleeve: Since the sub-adjustment is directly on the weaving machine, we have used a special sleeve for the warp shaft of the pulp machine to directly control the tension.

3.3 Yarn path: The four warp beam paths are placed in the lower layer of the creel frame to reduce the path of the yarn into the pulp groove and ensure that the yarn enters the slurry groove as soon as possible so that the yarn is less stretched in the yarn pull. Good unwinding tension.

3.4 Drying room temperature: In the process of starting up the dyed yarn, the speed of the dyed yarn is slow, and it is difficult to control the temperature of the drying cylinder and the setting of the squeezing force. If the temperature is too high, the warp yarn will be dry and the yarn will become wet. The rate is low, the recovery ability of the yarn after the stretching force is stretched is poor, the elongation at break thereof is reduced, and brittle fracture easily occurs in the weaving process, which affects the efficiency of the loom. In the idle process, the squeezing force should be appropriately weakened, or the thickness of the sizing film is too small and the effect of hairiness sticking is poor, resulting in unclear opening after the looms, so the pre-bake temperature is set to 80 degrees, and the main baking temperature is to 60 degrees. , ensure that the yarn moisture and moisture, making the opening easy to wear.

3.5 Warp beaming: A movable twisted rod holder is set at the front of the creel frame and is used for slitting the warp beam. When the yarn runs to five twisted wires, the parking will be The wrought bar is inserted into the stranded wire and the wrought bar is fixed on the shelf. Adding the wringing bar here is to make the yarn break down to facilitate the lower stranding and eliminate the size of the slurry.

3.6 Frontal Stranding: Skilled Operation Techniques. Twisting each of the 20 varieties of this species, at the same time, in turn, the two pairs of people at the same time through the twist, wear time to be completed within 5 minutes to ensure that the yarn stay in the drying room is a short time, continuous head. The size twisting method must divide the yarn pieces equally, and the distance between the yarn pieces is 5cm. This prevents the yarn pieces from being uneven in tension due to the number of the yarn pieces and causing the yarn to break at the divided skein bars.

4 , the process of control

4.1 Sizing: "Five Sets": "Five Sets" is the guarantee of quality during the sizing process. In the course of the tour, the value-changer should pay attention to the opening of the dry area, the sizing of the hand, the change of the slurry, etc. to control and adjust various types of data. For the problems to be solved in the colored yarn, whether the hairiness is obedient and the secondary hairiness is produced.

4.2 Application of Wet Separation: When the yarn emerges from the grout, the wet grinded wands are to be worn in the gauze. At this time, the gauze is divided into two layers in the wet zone. In the forest, Mao Yu was affixed to the movement of the wand.

4.3 Speed ​​Control: When the vehicle is parked and parked, the yarn will squirm, the elongation will increase, and the yarns will appear to be mutually twisted. Therefore, the vehicle speed is balanced, and reducing the speed of starting the slow car is the basis for guaranteeing a balanced tension and smooth sizing of the warp yarn.

4.4 Zone tension and elongation control:

(1) The tension of the warp beam unwinding: The data of preliminary setting and the deceleration stop yarn do not loosen, and it is necessary to ensure that the yarn does not entanglement elongation < 0 when the yarn arrangement is especially small.

(2) Feeding tank tension: According to the total number of yarns, the groove tension is obtained. The tension at this time should be less than the unwinding tension. Because the yarn passes through a plurality of inverted yarn rolls, the yarn tension is uniform, the tension cannot be too low, and the tension is < 0.5.

(3) Tension of the wet zone: It is the coordination of the tension between the slurry tank and the dry zone. When the car is running normally, the tension is too small to be grasped.

(4) Tension in the dry area: In order to ensure a smooth split and avoid loosening and breakage, attention should be paid to the coordination of the total tension in the front zone and the wet zone tension.

(5) Winding tension and pressure of stick pressure: Due to the tow stick's pressure tension stick and three sticks combined type transmission, the tension of the winding tension is matched with the pressure of the pressure stick to ensure the smooth and tight winding of the spool.

4.5 Falling-up axis: Pay attention to the coordination when adjusting the axis, and adjust the direction and width of the axis to the correct axis. In the shortest time, glue, drop shaft and upper shaft are adjusted. Adjust the edge yarn and the snail cannot be too long. Control tension.

in conclusion:

Through the control of the above difficulties, the efficiency of this type of loom is 88%. The variety of color fabrics is seen in "multiple varieties and small batches". Therefore, the determination of the whole slurry operation method should be adjusted according to the degree of difficulty of the varieties and the raw material conditions. Different varieties should adopt different sizing routes and process control points. Only continuous practice and exploration in the production process can continuously solve the production process. The problems that have occurred ensure that the quality of the spool provides excellent spools for weaving and produces increasingly finer fabrics.
