Edited by Tayyaba Rehman — By Urooj Arif — Updated on April 3, 2024
Fiber is a broad term for thread-like materials, used in textiles and biology, while fibrils are fine fibers, often found in cells and tissues.

Key Differences
Fiber refers to elongated thread-like structures that are fundamental in various applications, including textiles, dietary intake, and biological contexts. These structures provide tensile strength and flexibility to materials and biological entities. Whereas fibrils are a subset of fibers, specifically referring to very fine, thread-like structures that are typically found within cells or making up part of the extracellular matrix in biological tissues. Fibrils can be considered as the micro-components of larger fiber systems, playing critical roles at the microscopic level.
In the textile industry, fiber is a key term that denotes the raw material used to make yarn and fabric. These fibers can be natural, such as cotton, wool, and silk, or synthetic, like polyester and nylon. On the other hand, fibrils are not commonly referenced in textile manufacturing as they pertain more to the microscopic structure of certain natural fibers and their internal makeup rather than being a distinct type of raw material.
In dietary contexts, fiber refers to plant-based carbohydrates that cannot be digested in the human small intestine and are important for digestive health. Fibrils, however, do not have a direct role in dietary discussions. Instead, dietary fiber might consist of various molecular and microscopic structures, including fibrils, that contribute to its overall function in the diet.
In biological tissues, fibers are essential components that provide structural support and strength. These can include muscle fibers, nerve fibers, and connective tissue fibers. Fibrils, within this context, often refer to the finer structures that make up these larger fibers or that are components of the extracellular matrix, such as collagen fibrils, which are crucial for the structural integrity and function of tissues.
At the molecular level, fibers can refer to large, complex structures composed of many molecules, such as polymers in synthetic materials or cellulose in plants. Fibrils, in contrast, often denote the smaller, more specific structures within these larger complexes, showcasing the hierarchical organization of matter from the macroscopic to the microscopic scale.

Fiber
Fiber or fibre (from Latin: fibra) is a natural or man-made substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials.
Fibril
Fibrils (from the Latin fibra) are structural biological materials found in nearly all living organisms. Not to be confused with fibers or filaments, fibrils tend to have diameters ranging from 10-100 nanometers (whereas fibers are micro to milli-scale structures and filaments have diameters approximately 10-50 nanometers in size).
