**Introduction:**

The quantity of fabric is needed to make any definite apparel is called as

**Fabric consumption**. After completing the sample garments, to know about the price of the garments we must need to know the actual fabric consumption. There are two methods for**determining fabric consumption**.They are- Marker method
- Mathematical method

**Our today’s topic is Mathematical method.**How we will be able to detect actual fabric consumption for any garments ?

Lets see how to Detect fabric consumption for a Full shirt & Trouser

**Fabric Consumption Calculation for Full shirt:**

There is a theory for shirt’s fabric consumption, Z = x+y

Here, X = length of shirt X Width of shirt

And Y = sleeve length X Width of Arm hole

Again,

X= (A+3ʹʹ) X (B+3ʹʹ) X 2 inch²

Y= (C+2ʹʹ) X (2D+2ʹʹ) X 2 inch²

**Where,**

B = Width of the shirt

C = Sleeve length

D = Width of Armhole

Fabric consumption (inch²)

**Fabric length**=

**……………………………..…**

Width of fabric

**Mathematical problems:**

From Given Dimensions of full shirt, Find out how much length of fabric will be needed for making the shirt?

- Length of shirt = 30ʹʹ
- Width of shirt = 25ʹʹ
- Sleeve length = 21ʹʹ
- Width of Armhole = 22ʹʹ

**Solution:**Here,

A = Length of the shirt

B = Width of the shirt

C = Sleeve length

D = Width of Armhole

We have to find what square inch of fabric will be needed ?

And how much length of fabric needed ?

From theory we came to know that,

**Fabric consumption (Z)**= X + Y

= (A+3ʹʹ) X (B+3ʹʹ) X 2 + (C+2ʹʹ) X (2D+2ʹʹ) X 2

= (30ʹʹ + 3ʹʹ) X (25ʹʹ + 3ʹʹ) X 2 + (21ʹʹ+2ʹʹ)X (2 X 22ʹʹ + 2ʹʹ) X 2

= 33 X 28 X 2 + 23 X 46 X 2

= 1848+2116

= 3964 inch ²

When fabric width = 44 inch then,

Fabric consumption

**Fabric length**=

**……………………………..**

Fabric width

= 3964/44

= 90 inch

**Fabric Consumption Calculation for Trouser:**

Sketch of pant |

Generally a trouser is looked like figure “A”. But for finding consumption we need to draw another sketch like figure “B”.

Height and weight of the trouser should be measured and denoted as H & J respectively.

**Fabric consumption for trouser (P)**= (H+4ʹʹ) X (J+2ʹʹ) X 4

Here,

H=Weight &

J =Width through cork line(1/2)

**Mathematical problems:**

A trouser having height = 40, Width through cork line(1/2) = 13. Now find out the fabric consumption?

**Solution:**Given,

- Trouser’s height = 40ʹʹ
- Trouser width = 13ʹʹ
- Fabric consumption = ?

**Fabric consumption for trouser (P)**= (H+4ʹʹ) X (J+2ʹʹ) X 4

= (40ʹʹ+4ʹʹ) X (13ʹʹ+2ʹʹ) X 4

= 44 X 15 X 4

= 2640 inch²
