Basic Concept for Consumption in Apparel Industry

What is consumption?
In the apparel business, consumption means the quality of raw materials with a view to determining the price of a garment. In order to calculate the quantity of how much fabric, sewing thread, zipper, button, and other accessories are required to produce a garment up to the exporting is called consumption. In this article, we will discuss the basic concept for consumption in apparel industry.

Fabric Consumption Calculation System:
We can calculate and determine the consumption of fabric by the following two systems:

  1. Marker planning system
  2. Mathematical system

Basic information relevant to consumption:

  1. Measurement with technical specification
  2. Style description
  3. Fabric description
  4. Fabrics width / weight
  5. Washing shrinkage

Fabrics width:
Width of different fabrics is available thus: 35”, 45”, 50” and 60”.

Some measures and weights are as:

  1. 1 yds = 1260 sq inch if fabric width is 35 inch
  2. 1 yds = 1620 sq inch if fabric width is 45 inch
  3. 1 yds = 1800 sq inch if fabric width is 50 inch
  4. 1 yds = 1980 sq inch if fabric width is 55 inch
  5. 1 yds = 2160 sq inch if fabric width is 60 inch

Consumption can be made in two systems. The first and the second system are given below:

A detailed consumption of different parts of some garments is given below with illustrations.

Say, Fabric width = 45” – 1” (Shrinkage allowance) = 44”

…………………………………………………….Length X Width
Consumption Formula = …………………………………………………..
……………………………………………Fabric width X Fabric unit (36”)

Most of the apparel factories’ fabric consumption is made by pattern masters. The rest of the workers does not bother how it is done. If you have a product technical sheet then only you could calculate the exact fabric consumption of a garment. Average fabric consumption also depends on the nature of the fabric, like tubular or open width fabric.

Basic consumption formula:

 Consumption in grams= {(L*C) + (B*SL)}*2*GSM/10000 grams 

Where,
L= length of the body measure + allowance
C= Chest +allowance
SL= Sleeve length +Allowance
B=Biceps +allowance
GSM = fabric weight in grams per square meter

N.B: All length units are in centimeter
