The grammage of a fabric refers to the weight per unit area of ​​the fabric, generally expressed in grams per square meter (g/m2) or ounces per square yard (oz/Y2). The actual grammage weight is closely related to the finished product width, printing and dyeing process, yarn blending, and yarn count. The following grammage weights are calculated as simple formulas and are for reference only.
Non-elastic Burke weight calculation
a. Color cloth weight (g/m2):
  
Stretch cloth finished product weight (g/m2)
  
　　
Note: It is on the machine, finished product width.
Refer to the above formula for calculating the weight of the finished product in the same category. If the latitude and longitude direction is the line, due to the collapse, the weight of the finished product is heavier and the weight gain is approximately 1%. Due to the poor cotton blending and short fibers, the air-spinning yarn has a large fiber loss rate through the dyeing and mercerizing process. Therefore, the yarn coefficient is 24 or 24.3*0.95. This coefficient is an empirical formula, and the yarn count is more than 32s. accurate.
