Strength: Polyester fiber is nearly twice as strong as cotton and three times stronger than wool, making polyester fabrics strong and durable.
Heat Resistance: It can be used from -70℃ to 170℃, boasting the best heat resistance and thermal stability among synthetic fibers.
Elasticity: Polyester's elasticity is close to that of wool, and its wrinkle resistance surpasses other fibers, resulting in wrinkle-free fabrics with good shape retention.
Abrasion Resistance: Polyester's abrasion resistance is second only to nylon, ranking second among synthetic fibers.
Water Absorption: Polyester has low moisture regain and good insulation properties, but due to its low water absorption, it generates significant static electricity from friction, leading to poor dyeing performance.
As a clothing fiber, polyester fabrics achieve wrinkle-free and iron-free results after washing. Polyester is often blended or interwoven with various fibers, such as cotton-polyester and wool-polyester, and is widely used in various clothing and decorative materials. Industrially, polyester is used in conveyor belts, tents, canvas, ropes, fishing nets, etc., and its performance in tire cord is close to that of nylon. Polyester can also be used in electrical insulation materials, acid-resistant filter cloths, and pharmaceutical textiles. Synthetic fibers, due to their high strength, wear resistance, acid and alkali resistance, high temperature resistance, light weight, warmth retention, good electrical insulation, and resistance to mildew and insects, have been widely used in various sectors of the national economy.
