Sewing Thread Consumption Calculation

Sewing may be a method in the apparel industry - but it is also an art that brings life into fashion. Every stitch that is made, builds character in the garments we create. As retail fashion merchandiser we are proud of taking the pride in both precision and specialization in delivering unique apparel products, which are crafted by hand. For example; we transform fabrics into bold fashion statements. During this transformation there is a fashioning process called sewing. And for a professional merchandiser, it is very much necessary to understand the sewing thread consumption in apparel manufacturing.

Today, I am writing this article that will cover how we will be able to calculate the sewing thread consumption with practical calculation.

Firstly, let's take a very deep dive in the above picture that includes how much sewing tread we need to stitch one inch fabric by different sewing machine.

Practical Examples 1

• Let's be, a T-shirt having 113 inches of 3 Thread Over Lock stitches, 56 inches of 3 Thread Flat Lock stitches, 25 inches of 1 Needle Chain stitches, 14 inches of Single Needle Plain Machine stitches. Find out the consumption of sewing thread ?

Solution:

Now, from the above chart;

• For 3 Thread Over Lock, to stitch 1", sewing thread will be required: 15"
• For 3 Thread Flat Lock, to stitch 1", sewing thread will be required: 17"
• For Single Needle Chain, to stitch 1", sewing thread will be required: 11"
• For Single Needle Plain Machine, to stitch 1", sewing thread will be required: 2.75"

Here,

= {(113" of 3 Thread O/L)?+ (56" of 3 Thread F/L)?+ (25" of 1 Needle Chain stitch)?+ (14" of 1 needle P/M)} + 15% Wastage

= {(113" X 15")?+ (56" X 17")?+ (25" X 11")?+ (14" X 2.75")} + 15% Wastage

=(1695 + 952 + 275 + 38.5) + 15% Wastage

= 2960.5 + 15% Wastage

= 3405 Inches

= 3405 / 39.37 Meter (As; 1 meter = 39.37 inches)

= 86.48 Meters

Here, 86.48 Meters sewing thread will be required.

Practical Examples 2

• Let's be, factory need to buy thread cones with 2000 meters, Garments qty 2800 Pcs, Per body sewing thread consumption 86.48 meters. Now, calculate how many cones will be needed to stitch 2800 Pcs of garments ?

Solution:

= (Sewing thread consumption for per body X Total Garments Quantity) / Given thread amount in per cone.

= (86.48 X 2800) / 2000

= 242144 / 2000

= 122 Cones.

Here, 122 Cones will be needed to sew 2800 Pcs of garments.
