The splitting fiber technology was first developed commercially in Japan in the mid-to late 1960s. The production of microfibers or even nanofibers involves spinning and processing of the bicomponent fibers in the range from 2 to 4 denier per filament, after which the fibers are split into smaller filaments with denier of 0.1 or even less. Microfiber is defined as a staple fiber or filaments of linear density approximately 1 dtex or less, and above 0.3 dtex. The splittable fibre properties are microdenier, softness, drape and high surface area. The fibre used in the area like filtration, artificial leather, high performance wipes.
