Satees® continuous filament polyester thread
CF Nylon Thread
High-strength nylon sewing thread
Hongfeng Satess® filament nylon thread has higher strength and elongation properties than polyester thread. With soft and low friction characteristics, Hongfeng Satees can reduce the effects of needle heat and offer excellent abrasion resistance.

What is filament nylon thread?
The filament nylon thread product is a kind of industrial filament sewing thread with elasticity and high elongation. It is made of continuous filament nylon fibers twisted together. It is smooth and soft. , burning white smoke. High wear resistance, good optical rotation resistance, mildew resistance, coloring degree of about 100 degrees, low-temperature dyeing. It is widely used because of its high seam strength, durability, and flat seam, and can meet the needs of a wide range of different sewing industrial products.
Nylon Bonded Thread – Bonded Nylon Sewing Thread has a protective coating on the thread to prevent fraying, needle friction, and heat when sewing at high speeds. Bonding also helps prevent unraveling.
TIP: The Bonded Sewing Thread on the spool is normally slightly darker in color.
Chemical resistance of high-strength filament nylon sewing thread
- Bleaching Agents and Solvents: Nylon filament yarn can be bleached in most solutions, but is generally insoluble in most organic solvents. It is soluble in certain phenolic compounds.
- Hydrocarbons: Nylon threads have excellent resistance to hydrocarbons such as gasoline, diesel, and kerosene.
- Acids and Bases: Nylon threads are immune to most inorganic acids, except hot inorganic acids. It dissolves and partially decomposes in concentrated solutions of hydrochloric acid, sulfuric acid, and nitric acid. Soluble in formic acid. Inert in alkali.


Features of high-strength nylon sewing thread?
- Elongation – Nylon filament thread stretches about 26% over time.
- Anti-mildew, anti-aging, and sun-resistant – Nylon filament yarn has excellent anti-mildew and anti-aging properties, but prolonged exposure to sunlight can cause some deterioration. Polyester filament sewing thread or specially treated UVR nylon is better for prolonged exposure to sunlight. Nylon is usually fine if the seams are not exposed.
- Abrasion Resistant – Nylon filament thread has excellent abrasion resistance.
- Heat – The nylon filament thread will start to yellow around 300F. Prolonged exposure to temperatures above 285F will cause deterioration. Nylon filament thread starts to stick around 445F and melts around 485 to 500F.
Filament Nylon Thread Restrictions
Bonded nylon thread is popular for its versatility, durability, and dimensional strength.
Outdoor applications with prolonged exposure to sunlight. High-strength filament nylon sewing thread can withstand moderate sun exposure, provided it is not exposed to the sun for extended periods or has some kind of ultraviolet (UV) protection (such as windshields or unexposed seams). That’s why it is popular in automotive interiors, upholstery, and many other applications. It should not be used on outdoor furniture and sewing sails, awnings, or tarpaulins. In these cases, polyester high-strength thread or UVR nylon thread is a better choice. Polyester looks and feels similar to nylon and has a very similar size strength.
Flame Retardant Apparel and Gear – Nylon High Strength Sewing Thread will yellow at 300F, stick at 445F and melt at 500F. First responder clothing and equipment and some high-temperature conveyor belts require higher flame resistance. Use aramid or flame-retardant sewing thread in these cases. They are heat resistant to 600F or higher and will not melt. However, they do not treat UV light as well. Their price is much higher than nylon.
Critical Strength Requirements
Nylon is strong, but Kevlar (aramid) is about twice as strong. For example, 92-gauge nylon has a tensile strength of 15 pounds; Kevlar (aramid) in the same size has a tensile strength of 30 pounds. The downside to Kevlar (aramid) is that it costs about five times as much as nylon and is only yellow. Consider using heavier-weight nylon or double stitching for strength requirements.
COTTON APPEARANCE
Our nylon high-strength sewing thread has a smooth, shiny, shiny finish and is not suitable for garments that require a soft, fuzzy, cotton look. In these cases, cotton-spun polyester, and wool nylon is better and less expensive options.
Transparent or invisible suture Related categories: Monofilament thread. Monofilament is also made of nylon. It is constructed similarly to a fishing line and is classified separately.
Chemical Resistance
Nylon handles some chemicals well but not others.
