Hello, the price accounting formula of cotton grey cloth is: 100 meter yarn quantity * yarn price+weft density * processing fee per weft.

For example: 63 "21* 21108 * 58.

The yarn consumption for 100 m is 32.65 kg/100 m.

The price of C2 1 yarn is 19500 yuan/ton.

32.62 * 0.195+58 * 0.035 = 8.39 yuan/meter.

I hope I can help you.
