Continuous and/or discontinuous three-component fibers of the "sheath-core" type, provided with an external structure of the annular sheath type, made from polyolefin or co-polyester polymer material and an inner core or nucleus constituted of two different polymer materials such as, for instance, polyolefin resins and polyester resins, in suitable amounts. Process for the preparation of said three-component fibers and utilization thereof in the sector of civil and industrial engineering for making also short-cut multi-use fibers or "fiber-fill" for cotton-wool, and for use in paper-making or for realization of non-woven fabric to be used, for instance, in the health sector. |
