How do you calculate weaving?
To calculate the amount of weft, you need to know warp width, the number of picks per inch, and the length of the weaving. I usually add ten percent to that number for weft take-up. (So for an 8″ wide warp woven at 20 picks per inch for 65″: 8″ x 20 x 65″ = 10,400″ divided by 36″/yd = 288 yd plus 10% = 317 yd.
How do you calculate yarn consumption in weaving?
Calculate the yarn consumption per yard of a woven fabric of specification (20 X 16)/(128 X 60) X 58”, 100% cotton 3/1 twill fabric. Solution: The requirement of yarn for the fabric is to be calculated for both warp yarn and weft yarn separately because the warp and weft yarns are of the 20s and 16s respectively.
How is GSM calculated?
How to Calculate Fabric GSM by GSM Cutter:
- Cut the fabric with the GSM cutter (gram per square inch).
- Weight the fabric with the electric balance.
- The cut sample is 100 sq. cm. The weight of the cut sample is multiplied by 100.
- The result is the GSM of that particular fabric.
How do you calculate yarn cost?
By taking actual count-wise production rates achieved, consumable cost per kilogram of yarn is obtained. Standard packing material cost per kilogram of yarn is obtained by cost of items used (packing material) in unit packing and dividing by the package weight.
How is weft count calculated?
- Warp Weight in Kg = (Total Ends * Tape Length in meters)/(1693.6 * Warp Count)
- Weft Weight in Kg = (R.S in centimetres * cloth length in metres * PPI )/(4301.14 * weft Count)
- Cloth weight in GSM = {EPI/Warp Cout)+(PPI/Weft count)}* 25.6.
- oz (ounce ) per sq. yard = GSM(Grams per sq. meter)/34.
How is warp count calculated?
Take Ends/Inch and Multiply by Width in inches and 1.10. Divide this quantity by Warp count multiplied by 840. This will give you weight of Warp in pounds of one yard (a). To find the weight of the warp in one meter of fabric in grams multiply (a) by 1.09 and 1000 and divide by 2.2.
How do I calculate yarn count?
The direct system is calculated with the formula N = (W/l) / (L/w). The indirect system uses the formula: N = (L/w) / (W/l). In these formulas, N is the yarn count, W is the weight of a sample of yarn, l is the unit of length, L is the length of the sample, and w is the unit of weight.
