Good fiber elasticity of polyester fusible interlining

Polyester fusible interlining is favored for its good fiber elasticity, which has an important impact on the overall performance, comfort and durability of clothing.
Polyester (polyester fiber) has a unique molecular structure, and its chain polymer provides good elasticity. This molecular structure allows polyester to quickly return to its original shape after being stretched or compressed, avoiding wrinkles and deformation caused by daily wear. In addition, the fiber diameter and arrangement of polyester also affect its elastic performance. The design of fine fibers can enhance the softness and resilience of the fabric, so that it can maintain its shape under different environmental conditions.
Good fiber elasticity makes polyester fusible interlining good in wrinkle resistance. During wearing, the fabric will be stretched and squeezed due to activities, but when the external force disappears, the elasticity of polyester makes it quickly return to its original shape, reducing the formation of wrinkles. This feature enables polyester fusible interlining to provide a long-lasting smooth appearance when making suits, skirts and other clothing, meeting the high requirements of modern consumers for the beauty of clothing.
The elasticity of the fiber not only affects the appearance, but also the durability of the clothing. Because polyester has strong resilience, clothing can maintain its shape and structure after long-term wear or repeated washing, extending its service life. In contrast, some natural fibers such as cotton are prone to permanent deformation after being stretched, which affects the wearing experience.
