Polyester Sewing Thread
Filament Polyester Sewing Thread is made of slender polyester fibers twisted.
- Advantages: Excellent elongation (fibers can be stretched and recovered), smooth and fuzz-free, can be made into thick or thin threads.
- Disadvantages: Not as strong as core yarn (when comparing yarns of the same size), finer filament yarn may require tension adjustment.

Nylon Sewing Thread
Nylon sewing thread is one of many types of thread that are available for use with home sewing machines, as well as in industrial applications.
- The CF nylon sewing thread product is a kind of industrial filament sewing thread with elasticity and high elongation. CF nylon thread is made of continuous filament nylon fibers twisted together.
- Nylon sewing thread is smooth and soft. High wear resistance, good optical rotation resistance, mildew resistance. Coloring degree of about 100 degrees, low-temperature dyeing.
Nylon sewing thread is widely used because of its high seam strength, durability, flat seam, and can meet the needs of a wide range of different sewing industrial products.
