Why does Recycled polyester spandex fleece maintain its appearance and performance after multiple washes?

Recycled polyester spandex fleece maintains its excellent appearance and performance after multiple washes due to its unique combination of materials and manufacturing process. Recycled polyester fiber is made from recycled PET plastic and has a high molecular structure stability, which makes it excellent in stretch and abrasion resistance. This fiber is not easily deformed or relaxed due to mechanical friction or stretching during washing, so it can maintain the original shape of the clothing for a long time. In addition, polyester fiber has strong tolerance to water, detergents and agitation of conventional washing machines, and is not prone to chemical degradation or softening, so it can maintain its physical properties for a long time.

The addition of spandex provides excellent elasticity and resilience to the fabric. Even after multiple stretching or washing, spandex fibers can quickly return to their original shape to avoid the problem of loosening or wrinkling of clothing. In addition, spandex has a shape memory function, which can help the fabric maintain the original cutting contour, ensure the fit and comfort of long-term wear, and reduce permanent deformation caused by washing.

During the production process, Recycled polyester spandex fleece fleece is usually treated with high-temperature heat setting to make the fiber structure more stable, thereby reducing the possibility of shrinkage or wrinkling after washing. At the same time, the reasonable blending ratio optimizes the performance of the fabric, retaining the durability of polyester, and giving full play to the elastic advantages of spandex, avoiding the defects of a single fiber.

Fleece treatment forms a short and dense fleece layer on the surface of the fabric through brushing or raising technology, which enhances the bonding force between fibers and reduces the problem of pilling or fiber shedding caused by friction. In addition, the fleece layer can disperse the mechanical friction during washing and reduce the damage to the internal fibers, thereby maintaining the smooth appearance and soft touch of the fabric.

Recycled polyester spandex fleece fleece has the characteristics of fast drying, because polyester fiber has low water absorption, and the water evaporates quickly after washing, reducing the risk of fiber weakening or mildew caused by long-term moisture. At the same time, the fabric usually supports low-temperature machine washing or hand washing to avoid damage to the fiber caused by high-temperature washing, further extending its service life.

Recycled polyester not only meets the environmental protection requirements of sustainable development, but also has performance close to that of virgin polyester, and can even improve durability through special processes. This material not only ensures environmental protection, but also meets the needs of long-term use, making it an ideal choice for both eco-friendliness and high performance.
