Fabric Definition:
Cotton-Spandex blend is a highly comfortable, breathable, and exceptionally stretchy fabric that combines the natural softness of cotton with the superior elasticity and shape retention of spandex (elastane/Lycra).
Composition:
90-98% Cotton (Cellulose) + 2-10% Spandex/Elastane (Polyurethane) – typically 5% spandex for knitwear, 2-3% for woven fabrics
Texture:
Soft, smooth, and comfortable, with a noticeable mechanical stretch and excellent recovery; feels like pure cotton but with a subtle, elastic quality and a body-hugging fit
Stretch Level:
Moderate to High (2-3% spandex gives 20-25% stretch; 5-10% gives 40-70% stretch for activewear)
Fabric Construction:
Woven (e.g., Stretch Denim, Stretch Twill, Stretch Poplin) or Knitted (e.g., Cotton-Lycra Jersey, Rib, Interlock, Fleece)
GSM Range:
100-400 GSM (Light for t-shirts, medium for chinos, heavy for denim and sweatpants)
Breathability:
Excellent – Highly breathable; spandex does not hinder cotton’s breathability significantly
Moisture Management:
Moderate – Cotton absorbs moisture, but spandex is hydrophobic; moisture-wicking finishes can improve performance
Durability:
High – Good tensile strength; spandex improves abrasion resistance and shape retention; resists sagging and bagging
Thermal Properties:
Good – Similar to cotton; provides warm-weather comfort, with spandex adding a close fit that can feel warmer in winter
Key Usage Areas:
T-shirts, Leggings, Jeans, Chinos, Dresses, Underwear, Sports Bras, Activewear, Swimwear (blends), Yoga Pants, Loungewear
Medical compression garments, athletic supports, automotive upholstery (seats), industrial stretch covers
