Entangled nonwoven fabric made of two fibers having different lengths in which the shorter fiber is a conjugate fiber in which an exposed component thereof has a lower melting temperature than the longer fiber and method of making same

摘要

There is disclosed a fabric made up of short conjugate fusible fibers and longer, base fibers. The conjugate fibers have an exposed low melting point component having a lower melting point than the remainder of said fibers and said base fibers. In the method of the present invention, a web of short conjugate fibers and longer base fibers is passed through an entangling mechanism where the short fusible fibers are concentrated and intertwined in heavily entangled knot areas. The entangled web is heated to thermobond at least the low melting point component of the conjugate fibers to each other and preferably to the surrounding base fibers to reinforce and strengthen the fabric.
