Polyester fusible interlining has elasticity similar to wool

The elastic mechanism of polyester fusible interlining  is mainly reflected in the deformation and recovery ability of its fibers. When fibers are stretched by external forces, the interaction forces between molecular chains cause deformation of the fibers; And when the external force is removed, the mutual attraction between molecular chains promotes the fiber to quickly return to its original form. This process is similar to the elastic recovery mechanism of wool, but the elastic recovery of polyester is more rapid and stable, thanks to the rigidity and regularity of its molecular chain structure.
Factors affecting the elasticity of polyester adhesive lining fabric
Fiber fineness: Finer polyester fibers are more prone to deformation when subjected to external forces, but at the same time, they are also easier to recover, giving better elasticity to the adhesive lining fabric.
Fiber orientation degree: Polyester fibers with high orientation degree have more regular molecular chain arrangement, higher elastic modulus, and stronger elastic recovery ability.
Production process: Stretching, heat setting and other production processes have a significant impact on the elasticity of polyester adhesive lining fabric. Reasonable process parameters can optimize the orientation and crystallinity of fibers, thereby improving their elastic properties.
The selection of adhesive: The type and amount of adhesive also have a certain impact on the elasticity of the bonding lining fabric. High quality adhesives can reduce damage to the elasticity of polyester fibers while ensuring adhesive strength.
Application scenarios and advantages
Polyester adhesive lining fabric has a wide range of application prospects in clothing production due to its elastic properties similar to wool. In clothing such as suits and coats that require stiffness and shape stability, polyester adhesive lining can effectively support the fabric, preventing deformation and wrinkling. At the same time, its good elasticity also makes the clothing more comfortable and comfortable to wear, reducing the sense of restraint. In addition, polyester adhesive lining fabric also has good wear resistance, wash resistance, and wrinkle resistance, further improving the durability and aesthetics of clothing.
