In apparel industry, fabric
consumption is the common term for a garments merchandiser. In this industry,
most of the time profit or loss depends on the total consumption of fabric in
an order. So, bulk fabric consumption must be calculated correctly before start
bulk cutting of an order. For making profit from an order, we have to reduce
fabric wastage in bulk and make an accurate consumption of an order. As we
know, fabric is one of the most important part in garments costing and
represent almost 70% of total product manufacturing cost.

What is consumption?
In the garments trade,
consumption means quality of raw materials with a view to determine the price
of a garment. In order to calculate the above quantity how much fabric, sewing
thread, zipper, button and other accessories are required to produce a garment
up to the exporting is called consumption.
Internationally fabrics having
five types of width as in: 35 inch – 45 inch – 50 inch – 55 inch – 60 inch.
Generally, it is visible that after consumption of fabrics, we have to perform
some washing brushing or finishing treatment to develop fabric quantity.
In the circumstances stated
during fabric consumption we should consume fabric excluding 1-2 inch from the
fabric width. Otherwise in some cases buyer or factory authority may encounter
a great loss or may face difficulties. Consumption formula and other rules are
shown below. Remember that if consumption of a garment of different sizes is
required at a time, we have to figure out a consumption of the one size making
an average of all sizes for shortening the time consumption.
Types of consumption calculation system:
The quantity of fabric which is
required to produce a garment is called consumption. Whatever quantity of
fabric is required to produce a garment. We can know it through marker planning
and mathematical system. We can calculate and determine the consumption of
fabric by the following two systems:
- Marker
planning system
- Mathematical
system
Marker planning system:
In the system mentioned here
studying the range of size, following six pcs of six size can be stored out
from size range. As in XS, S, M, L, XL, XXL. Besides these we can choose three
pcs of three size or twelve pcs of twelve size for our convenience. It depends
on our IQ and the size range, thereafter paper pattern can be made by grading
to the above garments as per measurement sheet. Having made the paper pattern,
it should have to lay each parts of the paper pattern on a marker paper of
similar fabric width. After marking the paper pattern if we measure marker paper
to length wise, we will find an aggregate consumption of six pieces of garment.
If the aggregate is divided by six, we will find a consumption of one-piece
garment. As such we will find a consumption of one dozen garments from the
above system calculations. You can check bellow post for your easy understand:

- Knitted trouser fabric consumption system
Mathematical system:
Whatever is the fabric
consumption of a garment or whatever quantity of fabric is required to produce
a garment is measured by mathematical system. Mathematical system is system of
approximate estimation. Consumption of a sample garment or consumption as per
measurement sheet is calculated mathematically by measuring the area of length
and width of each parts of each pcs of garment.
