The biconstituent fiber consists of a continuous matrix of one polymer in which a different fiber-forming polymer is dispersed as a second distinct discontinuous phase.
The two polymers in the biconstituent fiber are mixed at normal temperatures before the polymers enter the extruder.
First, a biconstituent fiber is far finer than a bicomponent fiber.
Second, the irregular fineness of microfiber in biconstituent fiber make it more similar than natural leather.

The biconstituent fibers have many islands but no determinate area in cross-section and discontinue distributing in the fiber direction.
