Abstract: There is provided a process for preparing a partially-dissolvable and splittable conjugated microfiber with a cross-section having a matrix comprising orange-wedge shaped islands slightly connected with each other at the tips of the islands at a common matrix center. The conjugated fibers can be made into filaments and staple fibers. Filaments are spun, taken-up and then textured by means of a belt nip twister. The resulting texture yarns may then be partially dissolved, following weaving, to split. Staple fiber is processed into a non-woven fabric or, by spinning, to spun yarn and then by weaving thereof. The staple fibers can be made into fabrics such as suede fabrics, water-resistant and humidity-permeable high density fabrics, and peachskin fabrics.
