The so-called split flower is to determine the color of a warp color cycle The starting and ending positions of the arrangement. Its main purpose is to facilitate parquet use and processing, so that the color of the gray fabric surface is symmetrical and will not be biased to one side.
If the flowers are split improperly, the integrity of the pattern will be affected during the mosaic process, and it is not in line with the principles of economy, practicality and beauty. For example: a product has 20 side yarns x 2, and the inner warp color loop is 50 red yarns, 10 yellow yarns, and 10 white yarns, a total of 30 flowers. The following method is used to arrange: 20 border yarns, 50 red yarns, 10 yellow yarns, 10 white strands… 10 white strands and 20 edge strands. The result of arranging them in the above way is: the red is darker on the left and the white is lighter on the right.
When sewing strip fabrics or plaid fabrics, these strips or plaids will deviate to one side, which will damage the appearance of the fabric. If the red half is used as the starting point, the arrangement method is changed to: 20 edges, 24 red edges, and yellow ones. 10 strands, 10 white strands… 10 white strands, 26 red strands, 20 side strands. When the red hour is half-minute, there are 25 reeds on each side, which is inconvenient for threading the reed, so it is changed to 24 reeds on one side and 26 on the other side. Arranging the patterns in this way can make both sides of the fabric appear symmetrical or nearly symmetrical, which can increase the appearance of the fabric.
The position of textile splitting should be selected where there are many colored yarns, light color and tight texture. Specific notes are as follows:
(1) Regardless of whether the number of flowers in the whole frame is an integer or there are additions and subtractions, the split flowers are generally white or light-colored Where the grid pattern is relatively large, the colors on both sides should be arranged symmetrically or nearly symmetrically to keep the fabric appearance neat and facilitate parquet.
(2) For varieties that require higher pattern integrity, such as quilts, etc., the relationship between product width and pattern size should be considered when designing. For example, quilt fabric, in order to facilitate the use of double width, the number of flowers in the whole width should be an integer. It is better for women’s yarns sold in China to be scattered throughout the whole width. If there are any additions or subtractions, they should be minimized to reduce waste during sewing.
(3) The characteristics of the tissue should be considered when splitting. For jacquard fabrics with loose texture, satin strips and seersucker bubble parts, wick strips and flowered warp yarns, etc., they should not be close to the edge of the fabric. That is to say, it cannot be used as the starting point for splitting. There should be a plain or grained pattern about 1.1.5cm away from the edge of the cloth. Because the floating lines of these tissues are long or the structure is loose, it is easy to cause curling during weaving, or the edge yarns are pulled and broken, resulting in unclear openings or side brace defects, and they are easily torn by the cloth during finishing and tenting. . When the above requirements cannot be met, the number of edge yarns can be appropriately increased (for example, if the original edge yarn is 48, it can be increased to 56).
(4) Try to chop flowers in light-colored parts or parts with larger patterns. Because there are more counter-dyes when dyeing dark-colored yarn, it is easy to break when it is placed on the edge of the cloth during weaving.
(5) When splitting flowers, pay attention to the color of the cloth body that is close to the edge of the cloth. It should be the same or similar to the edge of the cloth. This will make the appearance of the fabric uniform.
(6) When splitting flowers, you should pay attention to the number of people wearing the reed teeth when getting on the machine. If the number of people wearing it is 2. The number of warp threads on each side after splitting must be an even number. For example, if the light blue has 70 strands, then after splitting, it will have 35 strands on each side. If it is inconvenient to reed, it should be changed to 34 strands on one side and 36 strands on the other side.
If the number of people wearing it is 3, a total of 13 reed teeth are needed for 39 red reeds. When splitting flowers, you should It is divided into 6 reed and 7 reed, that is, each side has 18 and 21 yarns.
(7)�Appearance, the flowers should be split from the lightest color with the largest number of roots, that is, starting with the white half. The adjusted color arrangement is:
white, yellow, black, red, black, red, yellow, red, black, yellow, and white
30 4 plus 8 9 4 9 8 40 4 30
After adjustment, the patterns on both sides of the fabric will be symmetrical to each other.
2. Special split flowers
(1) Approximate symmetry: For example, the total number of warp roots of a fabric is 752, The colors of the color cycle are as follows: 50 red strands, 10 black IU olive strands, and 10 yellow strands, a total of 70 strands. The full frame is 10 flowers plus 52 strands. The color meridian is arranged as follows: 50 red roots, 10 black roots, 10 yellow roots… 52 red roots/752 艉. Since there is only two warp threads difference between the left and right sides, it basically does not affect the pattern and it still looks symmetrical.
(2) Adjust the number of colored warp loops in each pattern: While keeping the total number of warp threads and the reed width unchanged, you can appropriately reduce or add a small amount of warp threads in the parts with more colored warp threads to reduce the number of warp threads in each pattern. The effect is changed so that the full-width flowers are scattered into integers. For example: The number of internal warp threads of a certain woman’s thread is 2610, and each flower is 180. The arrangement of the color meridian cycle is:
white red yellow black yellow basket red yellow black yellow red white
30 10 15 10 15 1010 15 10 15 10 30/180 roots
Therefore, the number of flowers in the whole frame is 2610/180=14 flowers plus 90 flowers. In order to make the whole flower into an integer, 6 are removed from the white part with the most yarn, then each flower is 174, and the whole flower is 15, which is an integer. The color warp is arranged as:
white red yellow black yellow blue red yellow black yellow red white
24 10 1510 15 10 10 15 10 15 10 30/174 roots.

Therefore, the number of full-width flowers is 2610/180=14 flowers plus 90. In order to make the full-width flowers is an integer, so if 6 are removed from the white part with the most yarn, each flower will be 174, and the entire width will be 15 flowers, which is an integer. The color warp arrangement is:
white, red, yellow, black, yellow, blue, red, yellow, black, yellow, red and white
24 10 1510 15 10 10 15 10 15 10 30/174 roots.
