Spun poly or spun polyester fabric is generally not known for its stretchiness. Spun polyester fabrics are often made from continuous filaments of polyester fibers that are twisted together or spun to create yarns. The resulting fabric tends to have limited stretch compared to fabrics made from elastane (spandex) or other stretch fibers.
Polyester itself is not inherently stretchy, and the stretch properties of spun poly fabrics primarily depend on the specific construction of the fabric and whether any stretch fibers are added during the manufacturing process. If a fabric is labeled as "spun poly stretch," it may indicate that some degree of stretch has been engineered into the fabric, potentially by incorporating stretch fibers or employing specific fabric construction techniques.
If you specifically need a stretchy fabric, it's advisable to check the product specifications, labels, or descriptions provided by the manufacturer to understand the stretch characteristics of the spun polyester fabric in question. Additionally, blended fabrics that combine polyester with elastane or other stretch fibers can offer improved flexibility and stretchiness.
