The good performance of polyester- ammonia knitted fabric in shaping effect is mainly due to the good combination of its unique fiber composition and knitted structure. This fabric not only inherits the toughness and stability of polyester fiber, but also incorporates the high elasticity and quick recovery of spandex fiber, thus reaching a new height in shaping ability.
From the fiber level, polyester fiber provides a solid foundation for fabrics with its high strength, high wear resistance and good wrinkle resistance. This stability ensures that the fabric is not easily deformed when subjected to external forces and can maintain its original shape and size for a long time. The addition of spandex fiber gives the fabric good elastic properties. The molecular chain structure of spandex fiber enables it to undergo large deformation under the action of external force and quickly return to its original state after the external force disappears. This characteristic is fully utilized in the knitted structure.
The knitted structure itself also provides strong support for the shaping effect. Knitted fabrics are made of coils that are intertwined and have great elasticity and ductility. When polyester-spandex knitted fabric is subjected to external force, its coils can deform to a certain extent to adapt to the curve changes of the body. At the same time, due to the high elasticity of spandex fiber, the fabric can fit closely to the surface of the body, showing smooth and beautiful lines.
More importantly, polyester-spandex knitted fabric does not simply "bind" the body during the shaping process, but provides the body with just the right support and wrapping feeling through its good elasticity and ductility. This support not only helps to shape and beautify the body shape, but also reduces muscle vibration and friction during exercise, improves exercise efficiency and reduces the risk of injury.
