A century ago, ramie clothed Chinese emperors. Today, it could become the backbone of the next generation of sustainable textiles, bridging the gap between performance and planet-friendly production.

What Exactly Is Ramie and How Is It Cultivated and Processed for Textile Use?

Ramie (Boehmeria nivea), sometimes referred to as China grass, is one of the oldest textile fibers known to humanity. Archaeological evidence shows it was used in ancient China as far back as 5,000–6,000 years ago, primarily for clothing, ropes, and ceremonial fabrics. Unlike cotton, which is a seed fiber, or wool, which is an animal fiber, ramie belongs to the bast fiber category, meaning it comes from the inner bark of the plant’s stalks.

What makes ramie especially attractive in 2025 is its combination of performance durability, natural sheen, and eco-friendly cultivation profile. The plant is perennial, capable of producing 3–4 harvests annually, and thrives in warm, humid climates. This makes regions like China’s Hunan, Jiangxi, and Sichuan provinces, as well as parts of India, the Philippines, and Brazil, ideal for ramie cultivation. Ramie comes from the bast fibers of Boehmeria nivea, a perennial plant harvested multiple times per year. After harvesting, fibers are extracted through decortication, purified via degumming, then spun into yarns and woven into fabrics for apparel, home textiles, and industrial applications.
