Introduction
Thread
price and thread cost are terms that are sometimes used synonymously
but may actually have very different meanings. Thread price usually
refers to the price you pay to get the thread to your plant and may or
may not include shipping and transportation charges. The cost refers to
all the costs related to thread performance including the purchase
price. Thread, whenever it is given any consideration at all, is often
treated as the primary item where a manufacturer or contractor can cut
costs. Many think, "All threads are equal in performance and the same -
so what colors do you have and what is your price?" However, consider
that, "Thread generally makes up only a small percent of the total cost
of a sewn product, but shares fully 50% of the responsibility of the
seam."
For example, a manufacturer in the Far East was making
cargo pants and then subjecting them to a stone-wash finishing process.
They were averaging 48 percent repairs after laundering. After
evaluating their situation, we recommended that they switch from a
locally produced low-priced spun polyester thread to a poly-wrapped core
thread.
Initially, they were very resistant to even consider this
change due to the higher selling price, but they agreed to a large
garment trial. When this sewing trial was completed the analysis showed
that they were now averaging less than 2% repairs after laundering using
the
higher performance thread. They also had fewer thread breaks on the
sewing floor so they had fewer re-stitched seams and produced a better
quality garment … not to mention that their sewing operators were able
to achieve production output and therefore lower their overall sewing
costs!
The plant manager still hesitated in purchasing this
higher performance thread and stated that labor costs in his country was
very inexpensive and he could afford to repair the garments. During our
discussion, we acknowledged that the core thread was more
expensive
and his labor rates were low, however, we pointed out that there were
other costs related to the thread performance. They included:
More
equipment & operators required: Additional sewing machines are
costly anywhere in the world. Higher overhead costs: Floor space,
utilities and power, training costs, and higher maintenance costs.
Longer In-process times. Penalties due to shipment delays.
Charge-backs
from Retailer when poor quality is found. Seconds due to poor quality
that could not be repaired: Material and other trim costs are very
expensive. Being recognized as a low quality producer. The realization
of these 'hidden' costs convinced this customer to make the right choice
by switching to the higher performing thread to minimize their overall
thread cost. Furthermore, there are additional ways to reduce thread
costs without compromising sewability and seaming performance.
How to Reduce Overall Thread Cost
The following list includes practical ways to reduce thread cost other than just using a cheaper thread
- Use natural or white wherever possible.
- Change to a less expensive thread type on loopers and on inside overedge seams.
-
Change to smaller thread sizes wherever possible: Looper threads on
chainstitch, overedge and coverstitch operations and generally on
component parts like cuffs, and pocket flaps.
- Reduce thread consumption.
Changing to Smaller Thread Sizes
Smaller
thread sizes are generally less expensive than larger thread sizes and,
therefore, smaller thread sizes should be used whenever possible. The
table to the right shows the difference in thread cost by going to a
smaller thread size in the Topstitching only.
On chainstitch and overedge seams, smaller looper threads can be used without sacrificing seam strength.
In many cases, this can reduce the thread cost for a sewn product by 10 to 15%.
Using White or Natural Instead of Dyed Thread
White
or natural threads are generally less expensive than dyed threads
because they don't have to be wet processed. The least expensive cotton
or cotton wrapped core thread is natural or an "off-white" color. Since
the natural color of polyester thread is white,
then the least
expensive polyester thread is white and not "natural" color. If a
"natural" or "off-white" thread is specified, the white polyester thread
will have to be dyed increasing its cost.
Change to a Less Expensive Thread Type
Changing
to a less expensive thread type is always an alternative, however, as
stated above, this can detract from the finished quality of the sewn
product unless considerable testing is performed. Generally, inside
threads can be changed with less of an impact on
the seam quality or
sewability. For example, a spun polyester, air entangled, or textured
polyester looper thread can replace a more expensive core spun thread on
loopers and overedge seams to reduce the total thread cost.
Reducing Thread Consumption to Minimize Thread Cost
Another
alternative to reducing thread cost is to minimize thread consumption.
This can be done by changing stitch types, using automatic start/stop
devices on the sewing machines, and monitoring thread waste. A two
thread overedge stitch consumes approximately 21% less thread than a
three thread overedge. If this stitch is only
being used to cover the
edge to prevent it from unraveling, this might be a good alternative
particularly considering that overedge stitches make up a large
percentage of the total thread consumed in a sewn product.
^^Summary^^
As
you can see from the information presented above, there are many ways
to reduce thread cost other than just using the cheapest thread.
There
is a difference between thread price and thread cost. Any thread
company worthy of your business should have training professionals who
can help you make the right choice to optimize your quality and cost.
