The so-called split flower is to determine the color in a warp color cycle The starting and ending positions of the arrangement are: to facilitate parquet use and processing, so that the color of the gray cloth surface is symmetrical and will not be biased to one side.
If the splitting is improper, the integrity of the pattern will be affected during the patchwork, and it is not in line with the principles of economy, practicality and beauty. For example: the edge yarn of a certain product is 20 x 2, and the inner warp and color warp are looped There are 50 red ones, 10 yellow ones, and white ones. There are 10 stems with 30 flowers in total, arranged in the following way: 20 stems on the side, 50 stems on the red stem, 10 stems on the yellow stem, 10 stems on the white stem… 10 stems on the white stem, 20 stems on the edge. The result of arranging them in the above way is: the left side is dark red and the right side is white.
When sewing strip fabrics or plaid fabrics, these strips or plaids will be biased 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 sides, 24 red strands, 10 yellow strands, 10 white strands… 10 white strands, There are 26 red strands and 20 strands on the side. When the red is half-cut, there are 25 strands on each side, which is inconvenient for reeding, so it is changed to 24 strands on one side and 26 strands on the other side. The pattern can be arranged on both sides of the fabric. Early appearance of symmetrical or nearly symmetrical shapes can increase the appearance of the fabric.
The position of textile splitting should be selected in a place with a large number of colored yarns, light color, and tight organization. Specific precautions are as follows:
(1) No matter whether the number of flowers in the whole frame is an integer or there are addition and subtraction heads, the split flowers are generally split in the place where the white or light-colored grid pattern is relatively large, and the colors on both sides are arranged symmetrically or far apartSymmetrical to keep the fabric looking neat and to facilitate patchwork.
(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. What about domestically sold women’s lines?It is better to scatter the full-width flowers as a whole. If there are additions and 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 textures, satin strips and bubble parts of seersucker, wick strips and flowered warp yarns, etc., they should not be close to the fabric.side. 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 fabric 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 split flowers in light-colored parts or parts with larger patterns. Because when dyeing dark-colored yarn, there are more counter-dyes, and when weaving, It is easy to break when placed on the edge of the cloth.
(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 is 2 Enter. The number of warp threads on each side after splitting must beEven numbers. For example, the light blue has 70 strands and each side has 35 strands after splitting. 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 the 39 red yarns. When splitting the flowers, they should be divided into 6 reeds and 7 reeds, that is, there are 18 yarns and 21 yarns on each side.
(7) When splitting flowers, towel lines and knot lines should be avoided as the starting point, because when the shuttle enters the shed, the opening height is small. When using towel lines and knot lines as the starting point, the friction will increase. Fire break increased.
1. General split flower
Generally, split flowers only require that the color warp arrangement on both sides is symmetrical or approximately symmetrical. For example: the color warp arrangement of the color matching cycle of a certain fabric is:
yellow black red black red yellow red black yellow white
4 40 S 9 4 9 8 40 4 60
Each flower is 186. The whole frame is IO flowers, arranged as above When the left side of the fabric is too dark and the right side is too light, which damages the appearance of the fabric, you should start with the lighter color and more roots, that is, start with the white half. The adjusted color warp is arranged as follows:
white, yellow, black and red Black, red, yellow, red, black, yellow and white
30 4 plus 8 9 4 9 8 40 4 30
After adjustment, make the patterns on both sides of the fabric symmetrical to each other.
2. Special split flower
(1) Approximate symmetry: For example, if the total warp number of a fabric is 752, the color matching The color meridian of circulation is listed as follows: 50 red roots, 10 black IU olive roots, and 10 yellow roots, a total of 70 roots.The pattern is 10 flowers plus 52 roots. 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 color meridian cycles of each flower: Under the premise of 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 warp threads of different colors to change the root effect of each flower so that the whole flower pattern is dispersed into an integer. 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 and white
30 10 15 10 15 1010 15 10 15 10 30/180 root
Therefore, the number of flowers in the whole width is 2610/180 = 14 flowers plus 90. In order to make the flowers in the whole width into an integer, 6 flowers are removed from the white part with more yarn, then each flower is 174, and the whole width is 15 Flowers are integers, and their colors are arranged as follows:
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.
