To determine the shell fabric of the polo shirt we have to exclude only collar part & cuff hem part. After getting all the measurements if we apply them into the following equation we will get fabric consumption of that particular part per dozen.

The equation is CPD= (L*W*GSM*12)/10⁷ 

Where, L= Length of the part, 

W= Width of the part ,GSM= 220

Objective:

To know the procedure to calculate the consumption of shell fabric of a polo shirt.

To find out the consumption of fabric used in a polo shirt practically in lab.

Fabric Consumption for different parts:

• Fabric consumption for body part.
•  Fabric consumption for Sleeves.
•  Fabric consumption for pocket.
• Fabric consumption for half-moon 

Fabric consumption for body part:

The length of the body part should be measure from the backside along the HPSL to body hem.

The width should be measure at the chest where it more wide than the other area.

The seam allowance & sewing allowance should be added to the main measurement as per types of seam & types of stitch.

Measurement obtained along body part:

Length= (75+2+1+2) cm

= 80 cm      

Here, Bottom hem sewing allowance= 2 cm; 

Neck sewing allowance= 2 cm; 

sewing allowance= 1 cm

Width= {55+ (1.5+1.5)2+5} cm

= 66 cm; 

where both side seam allowance for two part 6; seam for placket in lower part = 5 cm

Consumption/ dozen = (L*W*GSM*12)/10⁷

= (80*66*220*12)/10⁷

= 1.39392 kg/dozen

Fabric consumption for sleeves:

Sleeve length should be measure excluding sleeve hem

Sleeve width should be measure at armhole attaching area.

Measurement obtained in sleeve:

Length, L= (23 + 2+ 1+ 2) cm

= 28 cm;   where seam allowance = 4 cm & sewing allowance = 1 cm.

Width, W= = (28*2 + 3) cm

= 59 cm. Where seam allowance 2 cm & sewing allowance 1 cm.

Consumption/ dozen = (L*W*GSM*12)/10⁷

= (28*59*220*12)/10⁷

= 0.8722 kg/ dozen

Fabric consumption for pocket:

The length of pocket should measure at highest length of pocket.

The width of pocket should measure at wider part of the pocket.

Measurement obtained at pocket:

Length L = 11.5+ 3; where upper hem folded seam allowance= 2 cm & both end sewing allowance =1 cm.

= 14.5 cm

Width W= 11.5+ 1; where sewing allowance = 1cm.

= 12.5 cm.

Consumption/dozen = (L*W*GSM*12)/10⁷

CPD = (14.5*12.5*220*12)/10⁷

= 0.04785 kg/dozen

Fabric consumption for half-moon:

The length of half-moon should measure at highest length.

The width of half-moon should measure at most wider point.

Measurement obtained at half-moon:

Length L= 17+ 1 = 18 cm; where sewing allowance = 1 cm

Width W= 8.5 + 1.5 = 10 cm; where 0.5 cm seam allowance & 1 cm sewing allowance.

Consumption/dozen = (L*W*GSM*12)/10⁷

CPD = (18*10*220*12)/10⁷

= 0.04752 kg/ dozen

Fabric consumption:

0.04752 kg/ dozen (half-moon) + 0.8722 kg/ dozen (sleeve) + 0.04785 kg/dozen (pocket) + 1.39392 kg/dozen (body part) = 2.36149 kg/dozen

Total fabric consumption:

Total fabric + 7% wastage

= 2.5267943 kg/dozen.

Comments:

Fabric consumption is very essential to find out the quantity of fabrics required to produce a garments. The main reason of this consumption is to bring an assumption over costing of the garments. When a merchandiser asked to offer cost/ price for a new style of garments then he has to calculate the fabric quantity. So it is very important to know the process & procedure about fabric consumption therefore this experiment was very enjoyable to me.
