What are the chemical properties of flax fiber?

Flax fiber, primarily composed of cellulose, hemicellulose, and lignin, exhibits several notable chemical properties. It is hydrophilic, meaning it can absorb moisture, which affects its durability and strength when wet. Additionally, flax fiber is resistant to UV light and biodegradation due to its lignin content, making it suitable for outdoor applications. However, it is susceptible to alkaline and acidic conditions, which can degrade its structural integrity.
