Polyester filament high-strength thread is a type of sewing thread made from polyester filaments through special processing techniques. It has characteristics such as high strength and plays an important role in many fields. The following is a detailed introduction:
Raw Materials and Manufacturing
- Raw Materials: High-quality polyester filaments are selected. These filaments are composed of continuous polyester fibers, and the fiber length can theoretically be infinitely long. Compared with short fibers, they have better continuity.
- Manufacturing Process: Through a series of processes such as twisting and doubling, multiple polyester filaments are combined together to enhance the overall strength and stability of the thread. During the twisting process, an appropriate twist not only improves the strength of the thread but also affects its hand feel and gloss.
Performance Characteristics
- High Strength: This is its most prominent feature. Polyester itself has relatively high strength, and the filament form makes the fibers closely combined, further enhancing the strength. With the same thickness, the strength of polyester filament high-strength thread is much higher than that of ordinary sewing threads. It can withstand a large tensile force and is suitable for products with extremely high requirements for firmness.
- Excellent Abrasion Resistance: The continuous filament structure makes the surface of the thread relatively smooth. During the friction with the fabric, it is not easy to fuzz and break. It performs well in scenarios with frequent friction, effectively extending the service life of products.
- Low Elongation Rate: When subjected to tensile force, the elongation and deformation are minimal, ensuring the dimensional stability of sewn products. For some products with high requirements for dimensional accuracy, such as aerospace fabrics and high-end industrial products, this characteristic is crucial.
- Good Chemical Resistance: Similar to ordinary polyester threads, it has strong resistance to common chemical substances such as acids and alkalis. It can be used for sewing products that may come into contact with chemical reagents, such as chemical protective clothing and laboratory supplies.
- UV Resistance: It has a certain ability to resist ultraviolet rays. When exposed to sunlight for a long time, the performance of the thread is not likely to decline significantly due to ultraviolet radiation, making it suitable for sewing outdoor products.
Appearance Characteristics
- High Gloss: The filament structure makes the surface of the thread smooth, and the light reflection is uniform, presenting a high gloss. The stitch formed on the fabric surface is more eye-catching, adding a sense of refinement to products with decorative appearance requirements.
- Uniform Thread Body: The manufacturing process ensures that the thickness of the thread body is uniform. During the sewing process, it can smoothly pass through the needle hole and the fabric, reducing problems such as skipped stitches and broken threads, and ensuring the sewing quality.
Application Fields
- Industrial Manufacturing: In automobile manufacturing, it is used for sewing key parts such as seats and seat belts to ensure safety performance. In the aerospace field, it is used for sewing components such as wings and parachutes to meet the requirements of high strength and stability.
- Outdoor Products: It is widely used in the production of outdoor products such as tents, backpacks, climbing ropes, and sails. It can withstand harsh outdoor environments and large tensile forces and friction.
- Military Equipment: It is used for sewing many military equipment items such as military uniforms, military tents, and bulletproof vests. With its high strength, wear resistance, and chemical resistance, it meets the strict performance requirements of military equipment.
