About Aramid Sewing Thread

Para aramid yarn are made of Para aramid 1414 staple fiber after spinning, twisting and other processes. It is the high temperature sewing thread which is suitable for high speed sewing equipment.

Feature

High strength: strength can be achieved more than 20.0 cN/dtex, as well as is 5 times compared with steel and is 4 time of general chemical fiber material.

Low Density: much lower than steel, the density is only 1/5 of steel.

Excellent heat resistance: basically it does no loss of strength in the environment of 130 degrees; under condition of 240 degrees can be normal used; to about 560 degrees was carbonized decomposition and no melting point.

Chemical resistant: It will be affected that in high concentrations of acid and alkali environment using or exposing for long time.

Application

Para aramid fiber yarn often used for: high temperature resistant sewing thread, abrasion retardant sewing thread, high temperature sewing thread for dust filter bag, fireproof curtain sewing thread, cut resistant sewing thread for gloves, high strength high modulus aramid thread and other special functional sewing thread.

Exceptional Flame and Thermal Resistance

Aramid sewing thread is specifically designed to withstand extreme heat and flames. Its high decomposition point above 400C and flame retardant properties make it ideal for applications where safety is paramount, such as firefighting uniforms and industrial protective gear.

Customizable Specifications for Diverse Applications

Whether you need a particular twist per meter, unique color, or specific spool size, this thread can be tailored to your requirements. It is available in various sizes (20s/2, 30s/3, and more) and diameters, ensuring seamless integration into different sewing processes and end uses.

Reliable Performance in Harsh Conditions

The thread demonstrates exceptional resistance to UV, chemicals, and volatile matter. With a smooth, lubricated surface and strong, multifilament construction, it maintains integrity and tenacity even in demanding environments, supporting continuous operation and long-lasting durability.

FAQ's of Aramid Sewing Thread:

Q: How does aramid sewing thread benefit applications requiring fire protection?

A: Aramid sewing thread is inherently flame retardant with a Limiting Oxygen Index (LOI) above 28, which means it is self-extinguishing and prevents combustion. This makes it critical for sewing fire-protective clothing, firefighting equipment, and industrial textiles where fire safety is necessary.

Q: What is the recommended process for storing aramid sewing thread?

A: Store the thread in a cool, dry environment away from direct sunlight. Proper storage maintains its structural integrity, electrical insulation properties, and prolongs lifespan by preventing exposure to moisture and UV radiation.

Q: Where is aramid sewing thread most commonly used?

A: It is widely used in applications such as high-temperature sewing, protective apparel, firefighting gear, industrial filtration systems, and other environments demanding high tenacity and flame retardancy.

Q: What customization options are available for this thread?

A: The thread can be customized for color (yellow or other colors), twist per meter, spool size (including standard 1000m/cone), diameter (0.3-0.5 mm), and thread size (e.g., 20s/2, 30s/3), to suit various industrial and technical sewing needs.

Q: How does the thread perform under UV exposure and chemicals?

A: It offers excellent UV resistance and is highly chemical resistant, ensuring that it retains strength, tenacity, and color stability in outdoor, chemical, or hazardous working environments.

Q: What makes aramid sewing thread suitable for electrical insulation?

A: Thanks to its low water absorption, high nitrogen content, and stable structure, aramid sewing thread provides very good electrical insulation, making it suitable for use in technical textiles and protective equipment where electrical isolation is important.
