Nylon Thread Buying Guide
The Nylon Thread Buying Guide helps customers get the right thread for their needs. Our approach is to decide if nylon is the right thread for the job, identify which sizes (thicknesses) should be used, and finally pick the color and spool size that works. We have nylon thread in eleven sizes, over 100 colors, and putups ranging from small spools priced around $10 to discounted cases.

 

Selecting Nylon Thread

With nylon thread selection, understanding terminology, uses, limitations, and sizes are some of the most important considerations in order to ensure the best choice possible.

Nylon Thread Glossary

Bonded - A protective coating on the thread to resist against fraying, needle friction and heat when it is sewn at higher speeds. Other types of bonded thread we carry are Polyester, 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 nylon thread that is not sensitive to machine twist direction. It is about 10 to 14% stronger. But, it is thinner than regular nylon for reduced stitch appearance. Monocord usually requires a tensioning adjustment. Once it is made, it runs very smooth. UV rated nylon 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 nylon thread by the pound; hobbyists and casual sewers can save with our two and four ounce spools.

 

Other Terms

Soft - A nylon 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, it is easier to find in Polyester.

Nylon Thread Uses

Nylon thread is a great choice for sewing fabric, leather, canvas, and vinyl. We sell nylon thread in eleven sizes that range from hair-thin to cord-like. Our Use by Size Guide shows more details about selcting the best sizes or possibly better suited types of thread to use. This chart shows a list of some of the most popular uses for nylon thread.

Nylon Thread Limitations

Nylon thread is popular because of its 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.

Outdoor applications with prolonged sunlight exposure. Nylon thread can withstand moderate exposure to sunlight, provided that it is not exposed long term, or there is some sort of ultraviolet (UV) protection (e.g. windshields, or unexposed seams). This is why it is popular for automotive interiors, upholstery, and many other applications. It should not be used for outdoor furniture and sewing sails, awnings, tarpaulins. In these cases Polyester Thread or UVR Nylon thread are better choices. Polyester looks and feels like nylon, and has very close size-for-size strength. Its pricing is comparable to nylon.

 

Fire retardant garments and gear - Nylon thread yellows at 300F, sticks at 445F and melts at 500F. First responder garments and gear and some high temperature conveyer belts require much more fire retardance. Use Kevlar or Fire Retardant Sewing Thread in these situations. They are heat resistant to 700F or more and do not melt. However, they do not do well with UV. Their pricing is much higher than nylon.

 

Critical strength requirements - Nylon is strong but Kevlar Thread is about twice as strong. For example, size 92 nylon has a 15 pound tensile strength; the same size Kevlar has a 30 pound tensile strength. Kevlar's downside is that it costs about five times more than nylon and only available in yellow. Consider using heavier weight nylon or double-stitching to meet strength requirements.

 

Cotton-like look - Our nylon 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 also made from nylon. Its construction is similar to fishing line, and is categorized separately.

 

Chemical Resistance - Nylon does well with some chemicals and not as well with others. For more details, please see related topic: Nylon Thread Properties

 

Nylon Thread Information - All Topics

Nylon Thread Properties
Normal Wear and Tear

Elongation - Nylon 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 activewear and lighter materials, Woolly Nylon thread has a greater stretch. It is categorized separate from the nylon on this page as a serger thread. Kevlar Thread has about a 2% stretch.

 

Mildew, Aging, and Sunlight - Nylon thread has excellent resistance to mildew and aging, but prolonged exposure to sunlight causes some deterioration. Polyester or specially treated UVR Nylon are better for long-term exposure to sunlight. If seams are not exposed, nylon is usually okay.

 

Abrasion - Nylon Thread has excellent abrasion resistance.

 

Heat - Nylon thread will begin to yellow at around 300F. Prolonged exposure to temperatures over 285F will cause deterioration. Nylon thread begins to stick at approximately 445F, and melt at around 485 to 500F.


Chemical Resistance

Bleaches and Solvents - Nylon thread can be bleached in most solutions, but it is generally insoluble in most organic solvents. It is soluble in some phenolic compounds.

 

Hydrocarbons - Nylon thread has excellent resistance to hydrocarbons such as gasoline, Diesel, and kerosene.

 

Acids and Alkalis - Nylon thread is unaffected by most mineral acids, except hot mineral acids. It dissolves with partial decomposition in concentrated solutions of hydrochloric, sulphuric, and nitric acids. Soluble in formic acids. Substantially inert in alkalis.

Nylon Thread Information - All Topics

Nylon 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 nylon 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.

Thread Size to Material Ounces

The material that you are sewing costs far more than the thread. In most cases (with the exception of parachutes) 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: Nylon Thread Sizes 15 to 33
6 to 8 Ounce Fabric: Nylon Thread Sizes 33 to 46

8 to 10 Ounce Fabric: Nylon Thread Sizes 69 to 92
12 to 14 Ounce Fabric: Nylon Thread Sizes 92 to 207

Comments
There other things to consider. You may 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: Nylon Thread Sizes 33 to 207
8 to 12 Ounce Leather: Nylon Thread Sizes 138 to 277

12 to 16 Ounce Leather: Nylon Thread Sizes 207 to 346
Multiple Layers of Leather: Nylon Thread Sizes 207 to 346

Comments
There other things to consider. You may 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.

Nylon Thread Spool Sizes

We sell most of our nylon thread in 4 and 16 Ounce (1 Pound) spool sizes or 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.Nylon 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 nylon 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.

Nominal 6 Oz Spool
Minimum: 6.0 Oz.
Maximum: 7.9 Oz.

Nominal 8 Oz Spool
Minimum: 8.0 Oz.
Maximum: 10.5 Oz.

Nominal 12 Oz Spool
Minimum: 10.6 Oz.
Maximum: 15.5 Oz.

Nominal 16 Oz Spool
Minimum: 15.6 Oz.
Maximum: 19.9 Oz.

 

Nominal Yards by Size

Although 4 and 16 ounce spools are by far our most common spool sizes, other spool sizes are occasionally available. Even if a particular spool size is unavailable, this chart can help to estimate the amount of thread needed, or what is left on an already used spool.

Spool Dimensions

All of our nylon 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"
8 Oz - Base: 3.0", Height: 5.25"

Average Spool Dimensions
12 and 16 Oz By Brand
A&E - Base: 4.5", Height: 7.5"
Eddington - Base: 4.5", Height: 6.5"
Fil-Tec - Base: 4.5", Height: 7.5"
Service Thread - Base: 4.5", Height: 6.5"

Inside Diameter
The inside shaft diameter of all spools
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.

Leather - Lightweight (Notes)
Favorite lightweight leather projects include bags, bookmarks, book covers, coasters, jewlery, pillows and slippers. Listed sizes are the most popular. Thicker sizes can be used depending on desired stitch appearance. For hand stitching, we also sell Beeswax. Waxing makes the thread stronger, stiffer, and more moisture resistant. It also helps thread to feed easier through puncture holes. We also carry waxed thread, but sizes start at just over size 138 (Tex 165).
