01 When the finished door width is determined, the total number of warp threads can be determined according to the product of the door width and the finished warp density. According to the different organizational structure, the difference in the shrinkage of the finished product determines the door width of the grey cloth. The flat weft shrinkage is small, so the grey cloth door width is correspondingly small, the satin weft shrinkage is large, the grey cloth door width is correspondingly small. Because its product is the total number of warp, is fixed, therefore, plain cloth, warp density, and satin weft density is small. Because the total number of warp is certain, the amount of warp is the same, but the amount of weft is used with the expansion of the door width.

02 After determining the door width of the grey cloth, the door width of the grey cloth can be determined. Generally speaking, the weft shrinkage of different looms is different, and there are many influencing factors. The fabric of the same size is not used on the loom, because the opening size, tension and other parameters are different, resulting in different weft weaving shrinkage.

03 The organization has an impact on the width, the greater impact between the upper door and the grey cloth door is the weaving shrinkage rate, the greater impact from the grey cloth door to the finished door is the dyeing shrinkage rate (including post-finishing and pre-shrinking treatment, etc.), the influence of the organization on the door width depends on whether the structure is tight.

04 In the Sanhara tissue, such as: cotton 40* 32/150 *78 *63 "(1/1) weaving is difficult, if it is satin, it is less difficult to weave, if it is 2/1 twill, it is more difficult to weave.

Order of difficulty coefficients: 1/1 > 2/1 > 2/2 > 3/1 > 5/3 satin

In the reed calculation, to consider the total number of warp and how many into a reed, such as improper selection will lead to unclear opening and yarn broken problems.

05 The same specifications, different penetration numbers (two-in and three-in reeds, especially the plain texture style is not the same).
