naturfibra

naturfibra is a term used to describe natural fiber materials derived from renewable plant sources that are used in textiles and industrial applications. It denotes fibers processed with traditional or modern methods, with a focus on sustainability. It is not a single standardized material; definitions vary by manufacturer.

Sources include flax, hemp, jute, cotton, ramie, sisal, pineapple leaf fiber, and other bast or leaf fibers. Processing involves extraction of fiber through retting, decortication, cleaning, and sometimes chemical or enzymatic treatments, followed by carding, spinning, and weaving or knitting, or the production of nonwoven mats and composite reinforcements.

Uses include apparel, home textiles, upholstery, geotextiles, packaging, and reinforcement in polymer composites. Material properties vary by fiber type and finish, including strength, stiffness, moisture absorption, and thermal insulation; durability and colorfastness depend on processing and finishing.

Environmentally, naturfibra fibers are generally renewable and biodegradable, with potential lower energy use and carbon footprint than synthetic fibers, though effects depend on cultivation practices and processing, especially retting chemicals. Economic considerations include price volatility and scalability; certifications such as GOTS, OEKO-TEX, and regional standards may apply.
