Black Stretch Lace Trim is a specialized narrow fabric characterized by its openwork, patterned design and inherent elasticity. Its defining technical characteristic is its elongation capacity, typically ranging from 15% to 25%, achieved through the incorporation of elastane (spandex) fibers, usually constituting 3-5% of the total fiber content, woven or knitted alongside the base yarns like nylon, polyester, or cotton. This construction results in a material with a specific weight often between 30 to 100 grams per square meter (GSM), making it exceptionally lightweight and pliable.
