Knit Fabric Consumption Formula for a Basic T-Shirt

 




Suppose, one of the buyers has provided you the following measurement chart of a basic T-Shirt by mentioning the order quantity and fabric GSM. (Where Fabric is 100% cotton single jersey and fabric GSM is 160 and order quantity is 10000pcs). Then calculate the fabric consumption for this order.


Note:

  1. The types of fabric and their GSM will be confirmed by the buyer.
  2. For body length and sleeve length, an approximate sewing allowance (12cm) should be needed at the body hem, shoulder joint, sleeve hem, and armhole joint.
  3. For chest width, an approximate sewing allowance (6cm) should be needed at both side seams.
  4. And the approximate fabric wastage in various stages is 10%
  5. 1 dozen = 12 pieces; that's why the formula uses 12.


Solution:

Here, we will follow the measurement chart for XL size.

  • Fabric GSM- 160,
  • Total order quantity of clothing- 10000
  • Body length or shirt length- 79cm
  • Sleeve length- 43cm
  • ½ Chest width- 61cm


 (in kg)

 

 (in Kg)

= 3.45 +10% (in kg)

= 3.54 kg per dozen

Here,

1 Dozen = 12 pcs

So, 10000/12 = 833 dozens

Now, total fabric is needed for 10000 pcs garments = (833 X 3.54) = 2948 KG

Understanding Yarn Count: A Simple Guide

Yarn count is an important concept in the textile industry. It tells us how thick or thin a yarn is, and it relates the length of the yarn to its weight . In simple terms, yarn count shows the ratio of length to weight .  Two Types of Yarn Count Systems There are two main systems used to measure yarn count: Direct Count and Indirect Count . 1. Direct Count System In this system, the weight of a fixed length of yarn is measured. The weight per unit length determines the yarn count. The formula is: N = (I × C) / L Where: N = Yarn count I = Unit of length (like meters or yards) C = Weight of the sample L = Length of the sample In the Direct Count System , the length of yarn is fixed , and its weight varies based on the yarn's thickness. Common Direct Count Systems: Tex : The weight in grams of 1000 meters of yarn. Example : A 40 Tex yarn means 1000 meters of yarn weighs 40 grams. Denier : The weight in grams of 9000 meters of yarn. Example : A 150 Denie...
