This 85% polyester and 15% spandex swim fabric is a high‑performance material designed specifically for modern swimwear. It combines the strength and durability of polyester with the exceptional stretch and recovery of spandex, creating a fabric that is both comfortable and functional in and out of the water.Polyester is well known for its resistance to fading, shrinking, and wrinkling. In a swim context, its most important advantages are colorfastness and durability. The fabric maintains bright, vivid colors even after repeated exposure to chlorine, saltwater, and sunlight. This makes it an excellent choice for swimsuits that need to look new for a long time, including fashion swimwear, competitive swimwear, and resort wear.The 15% spandex content adds a high level of elasticity and body‑hugging fit. Spandex allows the fabric to stretch in multiple directions and then return to its original shape without sagging. This four‑way stretch capability ensures a snug, supportive fit that moves with the body during swimming, diving, surfing, or any other water activity. It provides good shape retention and helps garments hold their structure over time, even with frequent use.The surface of this swim material is typically smooth, soft, and slightly glossy, giving finished garments a sleek, professional appearance. It feels comfortable against the skin and reduces friction in the water, which can be especially beneficial for athletic or training swimwear. The smooth hand feel also helps prevent chafing during extended wear.Another key feature of this 85/15 blend is its quick‑drying property. Polyester does not absorb much water, so the fabric dries faster than many natural fibers. This improves comfort when moving from water to land and makes the material practical for swimwear, rash guards, active bikinis, and beachwear that may be worn for long periods.The fabric also offers good resistance to stretching out of shape, pilling, and general wear and tear. With proper care—such as rinsing after use, avoiding harsh chemicals, and drying in the shade—garments made from this material can maintain their fit, elasticity, and color over many seasons. The material can be produced in different weights and finishes, making it suitable for a wide range of swimwear styles, from sporty one‑pieces to fashion bikinis and men’s swim trunks with a close fit.In summary, 85% polyester and 15% spandex swim fabric delivers an ideal balance of durability, stretch, comfort, and fast drying. It is a versatile, reliable choice for high‑quality swimwear that needs to perform well in water while maintaining a flattering, supportive fit and a stylish appearance.
