High strength: Polyester thread is a synthetic fiber with very high tensile strength. This enables polyester spools to provide reliable strength and durability in various applications. Therefore, polyester spools are often used in situations that require high tensile strength, such as fishing, sewing, rope making, etc.

    Low elongation: The elongation of polyester thread is relatively low, and it can maintain a small elongation even under tension. This makes polyester spools outstanding in areas that require precise operation, such as fishing and navigation.

    Wear resistance: Polyester thread has excellent wear resistance and is not easily worn or damaged. This makes polyester spools perform well in environments that require long-term use and friction, such as for making ropes, fishing lines, etc.

    Chemical corrosion resistance: Polyester thread has strong resistance to some chemicals and is not easily corroded. This enables the polyester spool to maintain stable performance in some special environments, such as sea water.

    Lightweight: Polyester thread is a lightweight material that makes the polyester spool relatively lightweight and suitable for applications that require lightweight and good flexibility, such as fishing lines.

    Non absorbent: Polyester thread hardly absorbs water, which helps to maintain its original strength and weight, and can maintain relatively stable performance even when used in humid environments.

    Easy to process: Polyester thread is easy to process and manufacture, and can be made into various forms of wire through different textile and weaving processes, suitable for various purposes.

    Overall, polyester spools are widely used in various fields such as fishing, textiles, rope manufacturing, and industrial applications due to their high strength, low elongation, wear resistance, chemical corrosion resistance, lightweight, non absorbent, and easy processing characteristics.
