FABRIC CONSUMPTION | FORMULA OF FABRIC CALCULATON

 Fabric consumption refers to the amount of fabric that is required to create a particular garment or textile product. Fabric consumption is typically calculated based on the size of the garment or product, the design details such as seams, darts, pleats, and other factors such as the width of the fabric, the type of fabric, and any pattern matching that may be required.

Fabric consumption is an important factor in the manufacturing process, as it directly affects the cost of producing the garment or product. Accurately calculating fabric consumption can help to minimize waste and ensure that the fabric is used efficiently, which can help to reduce costs and increase profits.

There are various methods for calculating fabric consumption, including manual methods and computer-aided methods. Manual methods typically involve taking measurements of the garment or product and calculating the amount of fabric required based on these measurements. Computer-aided methods use software to calculate fabric consumption based on digital patterns and other design details.

There are several formulas used to calculate fabric consumption, and the specific formula used will depend on various factors, such as the type of garment, the design details, and the type of fabric used. Here are a few examples of commonly used fabric consumption formulas:

 

Basic formula:

Fabric consumption (in meters) = (Garment length + Garment width + Allowance) x (Garment height + Allowance) x Total number of garments / Fabric width

Formula for circular skirts:

Fabric consumption (in meters) = 2 x 3.14 x (Radius + Length of the skirt) x Total number of skirts / Fabric width

Formula for pants/trousers:

Fabric consumption (in meters) = (Garment length + Garment width + Allowance) x (Garment height + Allowance) x Total number of pants / Fabric width

In these formulas, "allowance" refers to the additional fabric required for seams, hems, and other design details, and "fabric width" refers to the width of the fabric being used. It's important to note that these are just examples of common fabric consumption formulas, and there may be other formulas used for specific garments or products.

Let's take an example of calculating fabric consumption for a basic A-line dress. Here are the measurements we will use:

 

Garment length: 100 cm

Garment width: 70 cm

Garment height: 170 cm

Allowance: 5 cm

Total number of dresses: 10

Fabric width: 150 cm

Using the basic formula I provided earlier, we can calculate the fabric consumption as follows:

 

Fabric consumption (in meters) = (Garment length + Garment width + Allowance) x (Garment height + Allowance) x Total number of garments / Fabric width

Fabric consumption = (100 + 70 + 5) x (170 + 5) x 10 / 150

Fabric consumption = 243.33 meters (rounded up to 244 meters)

 

So, to create 10 A-line dresses with the given measurements and allowances, we would need approximately 244 meters of fabric with a width of 150 cm. It's important to note that this calculation is just an estimate, and actual fabric consumption may vary depending on factors such as fabric shrinkage, pattern matching, and the skill of the person cutting and sewing the fabric.

Let's take another example of calculating fabric consumption for a basic men's shirt. Here are the measurements we will use:

 

Chest width: 100 cm

Shirt length: 75 cm

Sleeve length: 65 cm

Allowance: 5 cm

Total number of shirts: 20

Fabric width: 150 cm

Using the formula for shirts that I provided earlier, we can calculate the fabric consumption as follows:

 

Fabric consumption (in meters) = (Chest width + Allowance) x (Shirt length + Sleeve length + Allowance) x Total number of shirts / Fabric width

Fabric consumption = (100 + 5) x (75 + 65 + 5) x 20 / 150

Fabric consumption = 98.33 meters (rounded up to 99 meters)

So, to create 20 men's shirts with the given measurements and allowances, we would need approximately 99 meters of fabric with a width of 150 cm.

Again, this is just an estimate, and actual fabric consumption may vary depending on factors such as fabric shrinkage, pattern matching, and the skill of the person cutting and sewing the fabric.

In summary, fabric consumption is an important factor in the manufacturing process of garments and textile products. It refers to the amount of fabric required to create a particular garment or product, and it is typically calculated based on factors such as the size of the garment, the design details, the type of fabric used, and the width of the fabric.

 

Accurately calculating fabric consumption can help to minimize waste, ensure that fabric is used efficiently, and ultimately reduce costs and increase profits for manufacturers. There are several formulas used to calculate fabric consumption, and the specific formula used will depend on the type of garment, the design details, and the type of fabric used.

It's important to note that fabric consumption calculations are just estimates, and actual fabric consumption may vary depending on factors such as fabric shrinkage, pattern matching, and the skill of the person cutting and sewing the fabric. Nonetheless, accurately calculating fabric consumption is an essential part of the garment manufacturing process, and it helps to ensure that products are made efficiently and cost-effectively.
