# How to Calculate Fabric Weight in Textile Industry?

Fabric Weight Calculation in Weaving:

Fabric weight calculation is one of the most important factors to know for all textile engineers. A few times you have to ask someone about fabric weight calculation in your job profession. There are so many who still don’t know the manual calculating process of it. We know that fabric weight can be calculated in different ways, where one of them is by using a GSM (Gram per square meter) cutter.
After cutting the fabric by using a GSM cutter, the fabric has to weight in yards per one pound. After that, the weight of the one-yard or meter is recorded in grams or ounces and the fabric is then classified by its weight. This article has presented an easy manual method for calculating fabric weight which will be very useful for your textile job profession.

### Woven Fabric Weight Calculation Method Followed in Textile:

Fabric weight calculation has to solve from fabric specification. In textile weaving sector, fabric specification has mentioned by the following ways:

Fabric specification,
Ends per inch (EPI) × Picks per inch (PPI)
=…………………………………………………….….. × Fabric width
Warp count × Weft count

Or,
Warp count × Weft count
=……………………………………………………….. × Fabric width
Ends per inch (EPI) × Picks per inch (PPI)

Example:
Calculate the fabric weight of 1200m fabric by following the below fabric specifications:
10×10
=……………… × 50
75×60

Solution:
Given that,
In the case of warp,
Ends per inch (EPI) = 75,
Warp count= 10,

So,
Fabric weight= (warp weight+ weft weight) …………………………….. (1)

In the case of warp,

Total number of warp= (75×50) =3750
Length of each end= (1200m+ 1200×2% crimp) = 1224m

The total length of warp,
= (Total number of warp× Length of each end)
= (3750×1224) m
= 4590000m

Now,
Warp count,
Length (m) × unit weight (kg)
=………………………………………….
Unit length (m) × weight (kg)

Or,
Weight (kg),
Length (m) × unit weight (kg)
=………………………………………….

Unit length (m) × warp count

{4590000× (1×0.4536)}
=……………………………….…..

{(840×0.9144) ×10}

N.B: {(1pound=1×453.6gm=0.4536kg) and (840yds=840×0.9144m)}

=  271.06kg

So, the weight of warp is 271.06kg

In the case of weft,

Picks per inch (PPI) = 60,
Weft count= 10,
Fabric length= 1200m,

Now,
Length of each weft= (50+50×5% crimp) = 52.5inch= (52.5/39.37)m= 1.33m
Total number of weft= (60×39.37×1200×1.33) m= 3770071.2m

Again,
Weft count,
Length (m) × unit weight (kg)
=…………………………………………….
Unit length (m) × weight (kg)

Or,
Weight (kg),
Length (m) × unit weight (kg)
=…………………………………………….

Unit length (m) × weft count

{3770071.2× (1×0.4536)}
=………………………………………

{(840×0.9144) ×10}

=  222.64kg

So, weight of weft is 222.64kg

Finally, from equation (1), we get,
Fabric weight= (271.06kg + 222.64kg) = 493.7kg

So, fabric weight for this calculation is 493.7kg
