In order to achieve the above object, the utility model provides a following technical scheme: a non-woven fabric capable of being elastically stretched transversely comprises an upper non-woven layer, connecting filaments and a lower non-woven layer; the bottom of the upper non-woven layer is fixedly connected with a connecting wire; the bottom of the connecting filament is fixedly connected with the top of the lower non-woven layer, and the connecting filament and the lower non-woven layer have the same width; the lower non-woven layer and the upper non-woven layer are fixedly overlapped, and the length and the width of the lower non-woven layer are equal to those of the upper non-woven layer.

Preferably, a row of connecting filaments are longitudinally arranged at equal intervals at the bottom of the upper non-woven layer, and the upper parts of the connecting filaments are fixedly connected with the upper non-woven layer in a melt-blown mode.

Preferably, the connecting filaments are made of elastic spandex fibers, and the width of the connecting filaments is equal to that of the upper non-woven layer.

Preferably, a row of connecting wires are longitudinally arranged at equal intervals at the top of the lower non-woven layer, and the connecting wires and the lower non-woven layer are fixed through ultrasonic welding.

Preferably, the connecting filament is fixed on the surface of the nonwoven fabric receiver in a pre-stretching way, and the upper nonwoven layer nonwoven fabric is directly sprayed on the top surface of the connecting filament.

Compared with the prior art, the beneficial effects of the utility model are that:

1. this practicality is through with the connecting wire is tensile fixed to non-woven fabric receiver surface in advance, makes to go up non-woven fabrics direct injection in connecting wire top surface, and convenient manufacturing need not to change the batching of non-woven fabrics and can produce elastic non-woven fabrics, opens product market, goes up non-woven fabrics and connecting wire melt-blown fixed, goes up non-woven fabrics and is fixed more thoroughly with being connected of connecting wire, and non-woven fabrics fold shrink is gone up in the drive after tensile connecting wire resumes.

2. This practicality is fixed with the connecting wire through ultrasonic bonding in non-woven fabrics layer down, makes the upper and lower two sides of non-woven fabrics be the non-woven fabrics, need not to distinguish the positive and negative when manufacturing the use, saves later stage manufacturing and distinguishes the process of positive and negative.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 5, the present invention provides an embodiment: a non-woven fabric capable of transverse rebound stretching comprises an upper non-woven layer 1, connecting filaments 2 and a lower non-woven layer 3; the bottom of the upper non-woven layer 1 is fixedly connected with a connecting filament 2; the connecting wire 2 is made of elastic spandex fibers, and the width of the connecting wire 2 is equal to that of the upper non-woven layer 1; the bottom of the connecting filament 2 is fixedly connected with the top of the lower non-woven layer 3, and the connecting filament 2 and the lower non-woven layer 3 have the same width; the lower non-woven layer 3 and the upper non-woven layer 1 are fixedly overlapped, and the length and the width of the lower non-woven layer 3 are equal to those of the upper non-woven layer 1.

Further, go up 1 bottom of non-woven fabrics layer and vertically equidistance arrange and have a row of connecting

wire
