Suppose, you receive a yarn dyed t-shirt order from buyer. Details as below
|
Style: |
100% cotton, Single jersey, 160 gsm yarn dyed round neck t-shirt. |
|
|
Color: |
Beige/Navy (only one combo) |
|
|
Quantity: |
10,000 pcs (in four sizes, S, M, L & XL) |
|
|
Stripe: |
Beige 7 cm & Navy 1.5 cm (Total LR = 8.5 cm) |
|
|
Considering L Size Body |
||
|
Body length: |
73 cm |
|
|
Sleeve length: |
19.5 cm |
|
|
½ Chest: |
52 cm |
|
Calculation of Fabric Consumption For Y/D
Cutting Body Length Calculation:
Total no of repletion to complete a body= BDY Length/ Total Length of Repetition
= (73/8.5)
= 8.58
But here we will count 9 repetitions for cutting & sewing wastage.
So, Body Length will be = Total Length of Repetition x No of repletion
= 8.5 x 9 = 76.5 cm
Considering the body length = 76.5 cm we can easily calculate the consumption of a Yarn dyed t-shirt by Normal Consumption Formula.
But be careful, during the bulk yarn booking you should booked the yarn based on the consumption you got by using pattern & marker. Some time I saw buyer asked for match the body stripe with sleeve then the cutting wastage become more than 5%.
Calculation of Yarn Consumption of Bulk Dyeing for Y/D
Fabric Consumption: 2.78 Kgs/dozen (considering total wastage 18%) you may use this for pricing.
Normally the wastage of yarn dyed garments depends on styling.
Normal wastage for yarn dyed:
Dyeing (yarn) wastage: 6%
Knitting wastage: 3%
Wash wastage: 5%
So, you should need 114 kgs yarn to produce 100 kgs fabric
Here,
Beige color stripe length= 7 cm
And Navy color stripe length= 1.5 cm
Total length of one repetition= 8.5 cm
Now we just calculate the percentage of each color in a body
Beige color stripe length
Beige color stripe Ratio= -------------------------------------- x 100
Total length of one repetition
= (7 / 8.5) x 100
= 82.35 %
Navy color stripe length
Navy color stripe Ratio= -------------------------------------- x 100
Total length of one repetition
= (1.5 / 8.5) x 100
= 17.65 %
So, Now if the consumption is 2.78 kg
Then
Beige color will be = 2.28933 kg (2.78 kg X 82.35%)
Navy color will be = 0.49067 kg (2.78 kg X 17.65%)
In this above way we can book the yarn for bulk production……….
