    • 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.
    • 一种非织造弹力织物(10),其包括弹性纤维层(1),并且在其至少一侧上设置有基本上无弹性的非弹性纤维层(2,3)。 这些纤维层(1,2,3)已经通过纤维交叉处的熔融粘合完全粘合,使得弹性纤维层(1)的构成纤维保持纤维形状。 非弹性纤维层(2,3)的构成纤维的一部分已经进入弹性纤维层(1)和/或弹性纤维层(1)的构成纤维的一部分已经进入非弹性纤维层 纤维层(2,3)。 非织造弹力织物优选通过将包含弹性纤维的纤维网叠加在包含非弹性纤维的网上来制造,将这些纤维网处于不连续状态进行热空气处理,使得空气通过纤维网,从而熔融粘合纤维 并且获得由这些纤维网组成的纤维片材,其彼此结合,在至少一个方向上拉伸纤维片材,然后将片材从拉伸状态下剥离。
