How To Determine The Width Of The Finished Machine And The Next Machine?
How to determine the width of the finished machine and the next machine?
01
When the finished door width is determined, the total warp number can be determined according to the product of the gate width and the warp density of the finished product. According to different organizational structure, the shrinkage of finished products determines the width of grey cloth. Plain weft shrinkage is small, so the gray fabric door width is also small, the satin weft shrinkage is large, and the gray fabric door size is small. Because its product is the total number of fixed roots, it is fixed. Therefore, plain weave fabric has high density of warp, while Satin weft density is small. The amount of warp yarns is the same because of the total number of roots, but the amount of weft yarn is increased with the enlargement of the door width.
02
After determining the door width of the grey cloth, the upper gate width of the grey cloth can be determined. Generally speaking, the weft yarns of different looms vary with different factors. The same size fabric on different looms, because of the different size of opening, tension and other parameters, causes weft shrinkage.
03
The influence of the width of the structure on the width is greater. The shrinkage rate between the upper gate and the gray door is larger than that of the fabric. The shrinkage rate of the fabric from the width of the fabric to the width of the finished door is the shrinkage (including finishing and pre shrinking). The influence of the structure on the gate width depends on whether the structure is tight.
04
In Sanyuan organization, such as: cotton 40*32 / 150*78 *63 "(1/1) weaving is very difficult, if it is satin, then weaving difficulty is smaller, if it is 2/1 twill, weaving is more difficult.
The order of difficulty coefficient is 1/1 > 2/1 > 2/2 > 3/1 > 5/3 satin.
In the calculation of reeds, the total number of roots and a few reeds should be taken into consideration. Improper selection will lead to unclear opening and broken yarn.
05
The same specifications, different penetration numbers (two reeds and three reeds, especially plain weave style are different).
