vezels

Vezels is the Dutch term for fibers or filaments. In general usage it denotes elongated, slender structures with a high length-to-diameter ratio that can perform mechanical or functional roles across different domains, including textiles, nutrition, and biology.

In textiles, vezels are the basic raw material that can be natural or man-made. Natural fibers such as cotton, wool, flax, and silk come from plants or animals, while synthetic fibers such as polyester, nylon, and acrylic are manufactured from petrochemicals. Fibers are processed into yarns and then into fabrics by spinning, weaving, knitting, or nonwoven processes. Their properties—strength, elasticity, moisture absorption, and dyeability—determine suitable applications.

In nutrition, dietary fibers refer to plant-based carbohydrates that resist human digestion. They are classified as soluble or insoluble. Soluble fibers (for example pectin, oats, and β-glucans) form gels and can modulate digestion and cholesterol, while insoluble fibers (cellulose, lignin) add bulk and support bowel regularity. A balanced intake supports gut health and metabolic control.

In biology, fibers describe filamentous structures such as muscle fibers, connective tissue fibers (collagen and elastin), and nerve fibers (axons). They provide structure, transmit forces, or carry electrical signals, depending on the tissue type.

From an environmental perspective, natural fibers are renewable and biodegradable, while synthetic fibers often rely on non-renewable resources and can shed microplastics. Efforts focus on sustainable harvesting, recycling, and developing bio-based or recycled alternatives.
