## How do you calculate the production of a loom?

Fabric Production Calculation

- Loom Speed = Motor RPM * (Motor Pully Diametre)/(Loom Pully Diametre)
- Loom Effeciency Percentage = (Actual Production/Calculated Production )* 100.
- Moisture Regain Percentage = {(Yarn Weight – Dried Yarn Weight)/Dried Yarn weight} * 100.

**How do you calculate PPI and EPI?**

In most fabrics, EPI is higher than the PPI.

- Step 1: Collect fabric swatch. Collect fabric swatch for which you are going to find EPI and PPI.
- Step 2: Make a square of one sq. inch on the sample.
- Step 3: Count number of ends and Picks inside those squares.

**What is RPM in weaving?**

The figure “2,105 rpm” means that 2,105 weft threads are inserted per one minute.

### How is knitting production calculated?

Needle Calculation Formula: Rib/Inter lock /Double jersey circular knitting machine needle = ∏DG×2 (two needle bed is here) Single bed flat knitting m/c’s needle = width× gauge. GSM = {WPI× CPI × (39.37)2×stitch length (mm) ×Tex /1000× 1000} g/m2. Stitch density = (WPI × CPI) inch-2 = (WPC ×CPC) cm-2.

**How is PPI weaving calculated?**

With the yarn that I am using, this weaves up weft-faced. After weaving 2 inches for my sample I counted the amount of picks that I had in the 2 inches and divided it by 2 in order to get my PPI.

**How do you calculate hourly production in knitting?**

To calculate knitting machine production by weighing the total production of one hour or one shift or one day….For a single jersey,

- Fabric width = 53 “, GSM = 150 , Yarn count(Ne) = 26S.
- Stitch length = 2.85 mm, Cylinder Dia(D) = 25″, Cylinder Gauge(G) = 24.
- No. of feeder = 75, R.P.M.of cyl. = 25, Time =8 hrs, Effi. = 80%

## How do you calculate GSM in knitting?

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 textile production?**

Calculations

- Grams per meter = 0.5905 / Ne.
- Grams per yard = 0.54 / Ne.
- Tex = den x .11 = 1000/Nm = Mic/25.4.
- Ne = Nm/1.693.
- DRAFT = (feed weight in g/m) / (delivery weight in g/m)
- DRAFT = Tex (feed) / Tex(delivery)
- DRAFT = delivery roll surface speed / feed roll surface speed.

**How do you calculate production rate?**

Calculate Productivity By dividing the number of products produced by the man-hours involved, you calculate the average production rate. As an example, if your employees produced 800 units in the 200 total man-hours during the week, divide 800 by 200 to calculate 4 units per man-hour.

### How do you convert grams to GSM?

GSM Formula

- Where Wg is the weight of the sample (grams)
- L is the length of the sample (cm)
- W is the width of the sasmple (cm)
- GSM is the grams per square meter (g/m^2)

**What is production formula?**

The production function is expressed in the formula: Q = f(K, L, P, H), where the quantity produced is a function of the combined input amounts of each factor. Of course, not all businesses require the same factors of production or number of inputs.
