Fabric Consumption Calculation for Woven Shirt

Introduction:

In garments trade, Consumption and Costing is the primary requisition for a merchandiser. Fabric cost bears approximately 40%-45% of the total cost of any garments. So, calculation of correct fabric consumption is very important to achieve the maximum profit from an order

Fabric consumption calculation method for woven shirt:

A garments merchandiser should identify each parts of a “woven long sleeve shirt” before starting the consumption calculation-

Parts of long sleeve woven shirt

Normally, a “woven long sleeve shirt” consists with the following parts-

1.    Body parts (Body Length + Chest width),

2.    Sleeve,

3.    Collar,

4.    Cuff,

5.    Collar Band,

6.    Pocket,

7.    Yoke.

 Suppose,

The buyer “GAP” forwards a “woven long sleeve shirt” item order (10000pcs) to you with the following specification.

Follow the below measurement chart.

Now, find the required fabric consumption for the order.

Solution:
Consumption method for the above order will be discussed in the below in part by part.

Let,
Fabric width- 55”
Wastage-10%

1. Fabric consumption for the Body Parts (Body + Chest):

Here, we will apply the following formula (Per dozen),

= {(Body Length from HSP + Allowance) × (1/2 Chest + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)

= {(76 × 56 × 2 × 12) / (55 × 36 × 2.54) (In Yds.)

= 20.31yds per dozen……………………………………………………………………….. (1)

So, consumption for the Body Parts (Body + Chest) is 20.31yds per dozen.
(Note: 2.54 used to convert into inch from cm and 36 used to convert into yds from inch).

Clarification of formula:

**Why 36
Ans: To convert inch into yard. 36 inch=1yard

**Why 55
Ans: Fabric width 55 inch. It may vary.

**Why 2.54

Ans: If Measurement is cm.

2. Fabric consumption for the Sleeve:

Here, we will apply the following formula (Per dozen),

= {(Sleeve Length + Allowance) × (Arm hole straight + Allowance) × 2 ×2×12} / (Fabric Width × 36 × 2.54)

= {(66 × 28 × 2 × 2 × 12) / (55 × 36 × 2.54) (In Yds.)

= 17.64yds per dozen………………………………………………………………………… (2)

So, consumption for the sleeve is 17.64yds per dozen.

3. Fabric consumption for the Collar:

Here, we will apply the following formula (Per dozen),

= {(Collar Length + Allowance) × (Collar width + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)

= {(44 × 8 × 2 × 12) / (55 × 36 × 2.54) (In Yds.)

= 1.68yds per dozen………………………………………………………………………………… (3)

So, consumption for the Collar is 1.68yds per dozen.

4. Fabric consumption for the Cuff:

Here, we will apply the following formula (Per dozen),

= {(Cuff Length + Allowance) × (Cuff width + Allowance) × 2 ×2×12} / (Fabric Width × 36 × 2.54)

= {(12 × 3 × 2 × 2 × 12) / (55 × 36 × 2.54) (In Yds.)

= 0.344yds per dozen……………………………………………………………………………. (4)

So, consumption for the Cuff is 0.344yds per dozen.

5. Consumption for the Collar Band:

Here, we will apply the following formula (Per dozen),

= {(Collar Band Length + Allowance) × (Collar Band width + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)

= {(33 × 4 × 2 × 12) / (55 × 36 × 2.54) (In Yds.)

= 0.63yds per dozen…………………………………………………………………………….. (5)

So, consumption for the Collar Band is 0.63yds per dozen.

6. Consumption for the Pocket:

Here, we will apply the following formula (Per dozen),

= {(Pocket Length + Allowance) × (Pocket width + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)

= {(14 × 11 × 2 × 12) / (55 × 36 × 2.54) (In Yds.)

= 0.735yds per dozen………………………………………………………………………. (6)

So, fabric consumption for the Pocket is 0.735yds per dozen.

7. Consumption for the Yoke:

Here, we will apply the following formula (Per dozen),

= {(Yoke Length + Allowance) × (Yoke Height + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)

= {(49 × 13 × 2 × 12) / (55 × 36 × 2.54) (In Yds.)

= 3.04yds per dozen………………………………………………………………………….. (7)

So, consumption for the Yoke is 3.04yds per dozen.

Now,
Total fabric consumption for the woven long sleeve shirt is-

= [{Number (1) + Number (2) + Number (3) + Number (4) + Number (5) + Number (6) + Number (7)} + Wastage%]

= {(20.31 + 17.64 + 1.68 + 0.344 + 0.63 + 0.735 + 3.04) + 10%}
= (44.379 + 10%) per dozen.
= 48.82yds per dozen.

So, total fabric consumption for the woven long sleeve shirt is 48.82yds per dozen.

And,
Total fabric consumption for 10000pcs (833.33 dozen) woven long sleeve shirt is (48.82 × 833.33) = 40680.59yds.
