Sewing thread material comparison: Performance differences between aramid, cotton and polyester

Aramid sewing thread: the leader in wear and corrosion resistance
Aramid is a high-performance synthetic fiber known for its excellent mechanical strength, thermal stability and chemical stability. Aramid sewing thread has become the first choice for many industrial products by taking advantage of these characteristics. Its wear resistance is particularly outstanding, and it can resist long-term friction and wear, and maintain good shape and function even under high load or high-speed operation. This means that clothing, equipment or industrial products made with aramid sewing thread can significantly extend their service life and reduce the frequency of replacement due to wear, thereby reducing costs.

In addition to wear resistance, aramid thread also shows good corrosion resistance to many chemicals. It can resist the erosion of a variety of chemicals such as acids, alkalis, and organic solvents, ensuring that in industrial environments that come into contact with these substances, such as chemicals, petroleum, and medical fields, the sewing parts will not fail due to chemical corrosion. This feature makes aramid sewing thread an ideal choice for manufacturing high-end products such as protective clothing, filter materials, and high-pressure vessels.

Cotton thread: a synonym for tradition and comfort, but limited wear resistance
In contrast, cotton thread, as a traditional natural fiber sewing thread, is favored for its good moisture absorption, breathability and biodegradability. Clothes sewn with cotton thread are comfortable to wear and suitable for daily wear and household items. However, in terms of wear resistance, cotton thread is not up to the task. It is easy to break due to friction and wear, especially in scenes with frequent activities or high-intensity use, such as outdoor equipment, sportswear, etc., the durability of cotton thread is obviously insufficient. In addition, cotton thread is also sensitive to certain chemicals, such as strong acids and strong alkalis, and long-term contact may cause fiber damage.

Polyester thread: strong wear resistance, but limited corrosion resistance
Polyester is a widely used synthetic fiber known for its high strength, wear resistance and good elasticity. Polyester sewing thread has therefore become a common material for many durable clothing and industrial products. In terms of wear resistance, polyester thread is competent for most daily and industrial applications, better than cotton thread. However, although polyester thread performs well in terms of corrosion resistance, its corrosion resistance may be affected when facing certain specific chemicals, such as certain strong oxidants or organic solvents, resulting in decreased fiber strength or deformation.
