We know that fabric consumption is the most important task for apparel merchandiser. Maximum time profit or loss depends on the total consumption of fabric in an order. So accurate consumption will reduce fabric wastage which will be beneficial to make cost effective apparels. So apparel merchandiser should have proper knowledge about consumption. T-shirt and polo shirt are very common apparels. These two type apparels are ordered in bulk amount by foreign garment buyers. In this article I will discuss how apparel merchandisers do consumption of t-shirt and polo shirt. I think this article will be very helpful for trainee merchandisers.
Consumption Calculation of a T-Shirt:
A measurement chart of a t-shirt is given below table:
| Points of measurement | Unit (cm) |
| Body length | 60 |
| ½ Chest | 45 |
| Sleeve length | 20 |
| Armhole circumference | 40 |
| Neck height | 2 |
| Neck circumference | 36 |
| Body fabric weight (gsm) | 140 |
| Rib fabric weight (gsm) | 175 |
Front and back:
Length x Width x 2
= (Body length + Sewing Allowance, SA) x (1/2 Chest + SA) x 2
= (60+3) x (45+2) x 2
= 5922 cm2
Sleeve:
Length x Width x 2
= (Sleeve length + SA) x (Armhole circumference + SA) x 2
= (20+3) x (40+2) x 2
= 1932 cm2
Total Fabric (in cm2)
= Front and back + Sleeve
= 5922 + 1932
=7854 cm2
Fabric consumption per Dozen,
784 x 12 x 140
= —————————– + 10%
10000000
= 1.45 kg/dzn
Neck binding (Rib fabric),
Length x 2 x Width
= (Neck height + SA) x 2 x (Neck circumference + SA)
= (2+1) x 2 x (36+2)
= 228 cm2
Fabric consumption per Dozen,
228 x 12 x 175
= ———————————————– + 10%
10000000
= 0.06 kg/dzn
Answer:
Body fabric = 1.45 kg/dzn
Rib fabric = 0.06 kg/dzn
Polo Shirt Consumption:
A measurement chart of a polo shirt is given below:
| Points of measurement | Unit (cm) |
| Body length | 62 |
| ½ Chest | 48 |
| Sleeve length | 22 |
| Armhole circumference | 40 |
| Collar height | 5 |
| Collar width | 24 |
| Cuff height | 2.5 |
| Body fabric weight (gsm) | 180 |
| Rib fabric weight (gsm) | 230 |
Front and Back:
Length x Width x 2
= (Body length + SA) x (½ Chest + SA) x 2
= (62 + 3) x (48+2) x 2
= 6500 cm2
Sleeve:
Length x Width x 2
= (Sleeve length – Sleeve Rib height + SA) x (Armhole circumference + SA) x 2
= (22 – 2.5 + 2) x (40+2) x 2
= 1806 cm2
Total Fabric (in cm2) = Front and Back + Sleeve
= 6500 + 1806
= 8306 cm2
Fabric consumption per Dozen,
8306 x 12 x 180
= —————————————- + 10%
10000000
= 1.97 kg/dzn
In addition, polo shirt requires two flat knitted cuffs and one flat knitted collar.
Collar:
Length x Width
= (Collar height + SA) x Collar width (no allowance, as it is open)
= (5+1) x 24
= 144 cm2
Cuff:
Length x Width x 2
= (Cuff height + SA) x (Sleeve opening + SA) x 2
= (2.5+1) x (17.5+2) x 2
= 136.5 cm2
Total Rib fabric (in cm2) = Collar + Cuff
= 144 + 136.5
= 280.5 cm2
Rib Fabric consumption per Dozen,
…..280.5 x 12 x 230
= ——————————— + 10%
………10000000
= 0.09 kg/dzn
Answer:
Body fabric = 1.97 kg/dzn
Rib fabric = 0.09 kg/dzn
