**Abstract**

Natural fiber has a more long history and these are very important in a wide range of applications in the textile sector. Basically, natural fibers have biopolymers and natural fibers are basically made from either plant or animal-sourced. The plantbased natural fibers are major constituent of cellulose content and animal-based natural fibers are comprised of proteins. Nowadays, more used around the world for the plant-based natural fibers to bioplastics, biocomposites materials in automotive industries. These make product are low cost, low density, low manufacturing energy consumption, and more biodegradable. The ever-growing environmental, ecological, and economical concerns lead to increased acceptance of natural fibers in every area of conventional synthetic material application. This is due to biodegradability, nontoxicity, combustibility, easy availability, nonabrasiveness, and good specific strength. The present study focuses on the functional application aspect of natural fibers, basically an identification of fiber, classification and application of fibers process parameters.

**Keywords:** natural fibers, classification and application of fibers process parameters
