How do you calculate the production of a loom?

How do you calculate the production of a loom?

Fabric Production Calculation

1. Loom Speed = Motor RPM * (Motor Pully Diametre)/(Loom Pully Diametre)
2. Loom Effeciency Percentage = (Actual Production/Calculated Production )* 100.
3. 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.

1. Step 1: Collect fabric swatch. Collect fabric swatch for which you are going to find EPI and PPI.
2. Step 2: Make a square of one sq. inch on the sample.
3. 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,

1. Fabric width = 53 “, GSM = 150 , Yarn count(Ne) = 26S.
2. Stitch length = 2.85 mm, Cylinder Dia(D) = 25″, Cylinder Gauge(G) = 24.
3. 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:

1. Cut the fabric with the GSM cutter (gram per square inch).
2. Weight the fabric with the electric balance.
3. The cut sample is 100 sq. cm. The weight of the cut sample is multiplied by 100.
4. The result is the GSM of that particular fabric.

How do you calculate textile production?

Calculations

1. Grams per meter = 0.5905 / Ne.
2. Grams per yard = 0.54 / Ne.
3. Tex = den x .11 = 1000/Nm = Mic/25.4.
4. Ne = Nm/1.693.
5. DRAFT = (feed weight in g/m) / (delivery weight in g/m)
6. DRAFT = Tex (feed) / Tex(delivery)
7. 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

1. Where Wg is the weight of the sample (grams)
2. L is the length of the sample (cm)
3. W is the width of the sasmple (cm)
4. 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.
