Polyester Thread Buying Guide
Polyester thread looks, feels, and sews like nylon. You cannot tell the difference just by looking, and technical specifications like strength and stretch are very similar. This means that polyester works just as well as nylon in most applications including: upholstery, leatherwork, automobiles, banners and flags, sports gear, dog collars, horse saddles and tack, knife sheaths, gun holsters, fishing lures, and brief cases.

This guide specifically talks about industrial polyester thread, also known as filament polyester, or bonded polyester thread. There are other types of thread that are made of polyester including:
 
Embroidery Thread - We have many polyester embroidery threads on our Embroidering, Quilting, and Sewing Thread page featuring the Robison-Anton Super Brite Polyester in about 400 colors.
 
Spun Polyester - Much of the thread used for sewing garments is spun polyester sold under the names Maxi Lock and Excell. They look, feel, and sew like cotton. They are widely known as general purpose threads.

Selecting Polyester Thread
With polyester thread selection, understanding terminology, uses, limitations, and sizes are some of the most important considerations in order to ensure the best choice possible.
Polyester Thread Glossary
Bonded- Bonded polyester thread has a protective coating to resist against fraying, needle friction, and heat when it is sewn at higher speeds. Bonding also helps to prevent unraveling. It is important to note that colors of bonded threads appear slightly darker on the spool. Colors will become lighter when sewn. Other types of bonded thread we carry are Nylon, Nomex, and Kevlar.

Left Twist - The standard ply twist direction for almost every single-needle machine on the market. It is widely known as a Z-Twist, or Standard Twist. All of our thread is left twist unless otherwise noted.

Monocord - A single ply of polyester thread that is not sensitive to machine twist direction. It is about 10 to 14% stronger. But, it is thinner than regular polyester for reduced stitch appearance. Monocord usually requires a tensioning adjustment. Once it is made, it runs very smooth. Enhanced UV rated Polyester is more often available in monocord.

Size - A number designation given to a threads thickness, based on weight. We carry eleven different sizes from the ultra-thin Size 15, to the ultra-thick Size 554. The most popular size is Size 69. There are 3 main size standards: Commercial, Tex, and Government. Our product listings use commercial sizing. Our Specifications chart shows equivalent sizing.

Putup - Putup refers to the amount of thread on a spool. Commercial sewers generally by Polyester thread by the pound; hobbyists and casual sewers can save with our two and four ounce spools.

Non Wicking - Non wicking thread is treated to prevent water absorption. This is helpful when you are sewing things that are left outdoors. But, it only helps if the fabric is also water repellant. Non-wicking polyester thread may shred at faster speeds, and may also require a tensioning adjustment.

Other Terms
Soft - A polyester thread that is not bonded. It is suitable for sewing at slower speeds. It is better suited for gluing applications, because bonded coatings repel glues and adhesives.

Right Twist - This is widely known an S-Twist, and sometimes a Reverse Twist. It is more commonly used in double needle machines for banners.
Polyester Thread Uses
Polyester does better than nylon when you are sewing things that have prolonged exposure to sunlight (UV rays) and moisture. This means it is a better choice for sewing anything that is going to be used outdoors most of the time. It is important to distinguish between prolonged and occasional use. For example, a tent used for annual camping trips can be sewn with either nylon or polyester; a tent used to house a field operation for a season should be sewn with polyester.

Polyester thread has excellent UV resistance, but it does not provide the ultimate UV resistance. Pricey, plastic-looking brands like Sunbrella and Tenara that come with replacement guarantees will outperform regular polyester. Also, there are enhanced UV treated polyester and nylon threads that do better. None of this matters if the material sewn is not equally bleach and sunlight resistant. After all, the material makes up at least 90% of the content and cost of the item that is being sewn.

Polyester Thread Limitations
Polyester thread is popular because of its weather resistance, versatility, durability, and strength to size. There are applications where other types of thread may be better suited, depending on the conditions the end use will be under. This chart shows the most notable circumstances.
Fire retardant garments and gear - Polyester thread sticks at 440F and melts at 483F. This is too low for any application where thread and material must withstand high temperatures. Use Kevlar, Nomex, and PTFE Fiberglass threads in these situations. Kevlar and Nomex are heat resistant to at least 600F and do not melt; PTFE fiberglass protects to 1,000F.

Critical need for strength - Polyester thread is strong enough for the kinds of applications described so far. But, it is a bad choice for high stress applications such as conveyer belts because it can stretch up to 26% before it breaks. Size-for-size, Kevlar Thread is about twice as strong and much more expensive than nylon or polyester. For example, Size 92 polyester has a 14.5 pound tensile strength; Kevlar in that size has a 30 pound tensile strength. Also, Kevlar only stretches 2% before it breaks.

Cotton-like look - Our polyester thread has a smooth, glossy, shiny finish that does not go well with garments that need a soft, fuzzy, cotton-like look. In these cases, Cotton, Spun Polyester, and Wooly Nylon are better and less expensive choices.

Clear, or Invisible Stitching - Related Category: Monofilament Thread. Monofilament is made from nylon, and its construction is similar to fishing line.

Chemical Resistance - Polyester does well with some chemicals and not as well with others. For more details, please see related topic: Chemical Resistance
Polyester Thread Information - All Topics
Polyester Thread Properties
Normal Wear and Tear
Elongation - Polyester thread stretches about 26% over time. This is beneficial for its end use, because it allows for the seams to stretch with the fabric, allowing for 'breaking in'. For active wear and lighter materials, Woolly Nylon thread has a greater stretch. Kevlar Thread has about a 2% stretch.

Mildew, Aging, and Abrasion - Polyester thread has excellent resistance to mildew, aging, and abrasion.

Heat - Polyester thread begins to stick at approximately 440F, and melt at around 483F.
Chemical Resistance
Bleaches - In general, polyester thread has excellent resistance to bleaches and other oxidizing agents.

Acids and Alkalis - Polyester thread has excellent resistance to most acids, but it will dissolve with partial decomposition in concentrated solutions of sulfuric acids. It has a fair resistance to alkalis.

Hydrocarbons - Polyester thread has excellent resistance to hydrocarbons such as gasoline, Diesel, and kerosene.
Polyester Thread Sizing
Overview
Thread size is important because there are many considerations. The main ones are:
Machine Capability - Home, commercial and heavy duty sewing machines have different thread and needle size limitations.
Needle Size - Needles have sizes that are best suited for specific thread sizes and machine types.
Stitch Appearance - Are you looking for stitching to be inconspicuous, noticeable, very noticeable, or to be a focal point?
Strength - Is the thread a suitable strength for what is being sewn?
 
When polyester thread's size increases...
Commercial and Tex Equivalent numbers increase.
Machine capability requirements increase.
Thread diameter increases.
Thread strength increases.
Needle size increases.
Needle heat and friction increase.
Stitch visibility increases.
Fabric ounce per yard increases.
Leather ounce per yard increases.
Yards per pound decreases.

Polyester Thread Information - All Topics
Thread Size to Material Ounces
The material that you are sewing costs far more than the thread. In most cases, it is better for the thread to break than to have the stitches pull through the fabric. This means that the weight of the fabric, in ounces per square yard, is the best way to determine thread size. Here are size recommendations for fabric and leather.
Fabric Ounce to Yard and Thread Size Range
2 to 6 Ounce Fabric: Polyester Thread Sizes 15 to 33
6 to 8 Ounce Fabric: Polyester Thread Sizes 33 to 46
8 to 10 Ounce Fabric: Polyester Thread Sizes 69 to 92
12 to 14 Ounce Fabric: Polyester Thread Sizes 92 to 207
Comments
There other things to consider. You can use a thinner thread because your machine cannot handle a heavier thread, if it does not compromise safety. Or, you may choose a thicker thread because you want stitches to stand out. Selecting specific needle points designed for specific materials is recommended if a universal, round point needle won't suffice.
 
Leather Ounce to Yard and Thread Size Range
1 to 8 Ounce Leather: Polyester Thread Sizes 33 to 207
8 to 12 Ounce Leather: Polyester Thread Sizes 138 to 277
12 to 16 Ounce Leather: Polyester Thread Sizes 207 to 346
Multiple Layers of Leather: Polyester Thread Sizes 207 to 346

Polyester Thread Spool Sizes
We sell most of our Polyester thread in 4 and 16 Ounce (1 Pound) spool sizes, also known as putups. The smaller putups cost more per ounce than the larger ones. But, they are a better choice for one-time jobs, casual sewing, people who need a stash of many colors, and experimenters. Polyester thread is sold by weight (ounces, pounds) - not yards. This is because the number of yards-per-pound decreases as thread thickness increases. Selling by weight means prices for a given size spool are about the same across most thread sizes.

Nominal Spool Weights
Industry norms allow Polyester thread spool weights to vary by plus/minus 10% from the stated nominal weight. This means that customers get slightly less or slightly more thread than the nominal weight shown on our site. This chart shows our nominal weights and the thread-weight range (including the spool's weight) for various sizes. When spools fall within these ranges, we do not charge for when they go over or refund for when they go under. It is important to note that we usually do not charge when a spool goes over the maximum tolerance, but we will always refund when they go below the tolerance.
Nominal 2 Oz Spool
Minimum: 2.6 Oz.
Maximum: 4.5 Oz.

Nominal 4 Oz Spool
Minimum: 4.6 Oz.
Maximum: 5.9 Oz.

Spool Dimensions
All of our Polyester thread is wound on king spools unless otherwise noted. Most of our 2 and 4 ounce spools are wound in-house, and the spool sizes are consistent for those. Normally, manufacturer spool dimensions are consistent. There are some times one-off occasions where manufacturers will wind 12 and 16 ounce spools with different heights, but the base dimensions remain constant.
Average Spool Dimensions
2 Oz - Base: 2.5", Height: 4.5"
4 Oz - Base: 2.5", Height: 4.5"
6 Oz - Base: 3.0", Height: 5.25"

described, regardless of base and height,
is 1 inch.
Comments
For sewing machines not geared to handle these size spools, a Thread Cone Holder may be needed. It is designed to help machines bypass these limitations. There are also DIY thread cone holders that are can be made from PVC pipe, wire coat hangers, or coffee cups most notably. The advantage of a thread cone holder is that it is specifically designed for sewing.
We also carry 100 yard and 50 yard Hand Stitching Tubes. They are not particularly designed for machine sewing, but customers have created Do-It-Yourself adaptors.
It is important to note that DIY projects can cause machine damage or create tensioning issues if not made properly.

Marine (Notes)
Polyester thread works well for boat upholstery, sails, canapes, and covers because of its UV, moisture, and mildew resistance. There are threads designed for marine use that we do not sell. They outperform polyester over time. But, they are pricey.
Seam stress for sails, canopies and covers can vary widely.
For inside cabin upholstery, as in the case of yachts, nylon thread is suitable.
We have a limited selection of non-wicking polyester thread. It is treated to prevent water absorption. It is available in sizes 92, and 138 monocord. The easiest way to check for stock is to use our Search feature. The word wick will display all available items.
