NONWOVEN STRETCH FABRIC AND PROCESS FOR PRODUCING THE SAME

摘要

A nonwoven stretch fabric (10) which comprises an elastic fibrous layer (1) and, disposed on at least one side thereof, a non-elastic fibrous layer (2,3) which is substantially non-elastic. These fibrous layers (1,2,3) have been wholly bonded by fusion bonding at fiber intersections so that the constituent fibers of the elastic fibrous layer (1) retain a fiber shape. Part of the constituent fibers of the non-elastic fibrous layer (2,3) have come into the elastic fibrous layer (1) and/or part of the constituent fibers of the elastic fibrous layer (1) have come into the non-elastic fibrous layer (2,3). The nonwoven stretch fabric is preferably produced by superposing a web comprising elastic fibers on a web comprising non-elastic fibers, subjecting these webs in an ununited state to a hot air treatment so that the air passes through the webs to thereby fusion-bond the fibers to one another and obtain a fibrous sheet composed of these webs united with each other, stretching the fibrous sheet in at least one direction, and then releasing the sheet from the stretched state.
