How do you calculate warp and weft count?

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 weft calculated?

If it’s plain weave, twill, or lace weaves, this is usually the same number as warp threads per inch. Then you multiply that number (picks per inch) times the number of inches you’ll be weaving the piece times the width of the weaving plus about 10% (for example, by 11 inches for something 10 inches wide).

How do you calculate warp for 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 warp ends?

This is done by multiplying the number of ends by the total length, since each end needs to be the full length of the warp. So, in our example, the total amount of thread I would need is: 144 ends x 114 inches= 16,416 inches.

How is warp and weft cover factor calculated?

In cotton system cloth cover in particular direction (warp cover factor or weft cover factor) is calculated by taking the ration of threads per inch and square root of the yarn count (cotton count/English count).

How is weft insertion rate calculated?

Weft insertion rate is defined according to the following formula which is: WIR = PR (m/min) Where WIR = weft insertion rate P = loom speed in picks/min R = reed width in metre. Therefore it can be said that weft insertion rate is loom speed in picks/min multiply by reed width.

What is GSM formula?

Now, by applying all the data in the required formula, we can easily find out the above-woven fabric GSM. GSM (Gram per square meter), = (3.12 + 1.5) × 23.5.

How is warp shrinkage calculated?

To determine the take-up and shrinkage in width, divide the finished width by the width in the reed and you will get . 912, which is the total amount of width you would get from a 23” wide warp in the project’s yarn type. Resulting in about about 9% take-up.

How much yarn is needed to warp a loom?

I’d calculate 15% for take-up and shrinkage (that might be a little high, but it’s better to figure too much than too little). So you’d need to weave 65″ divided by . 85 or about 76″ measured on the loom. I’d therefore put on a 3-yd warp (108″), which would leave 32″ for loom waste; the loom waste would include fringe.

How will you determine warp cover factor?

What is warp yarn count?

How is GSM cutter and 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 the amount of weft?

Inches of weft for 1” of weaving = inches Total length of warp* X inches Total inches of weft = inches. / 36 = Total yards for weft yards.

How do you calculate the length of a warp?

WARP AND WEFT CALCULATIONS Warp Length Total length of warp* = inches cm A /36yards/100meters Warp Width(because the reeds are usually imperial, we will use the inches for the warp width) Total width of warp = inches C

How many yards of weft do I need for the weft?

Yards needed for the weft Inches of weft for 1” of weaving = inchesTotal length of warp* X inches Total inches of weft = inches / 36 = Total yards for weft yards

How much weft do I need to weave my project?

Inches of weft needed to weave one inch * Total inches to be woven = (This is your Project Length + Fringe + Take Up + Shrinkage in your warp) = Total inches of weft needed (The total amount of weft needed to finish your project right!) Total inches of weft needed / 36 = Totals yards of weft needed
