THREE-DIMENSIONAL BAG OF NON-WOVEN FABRIC AND PROCESSING METHOD

Disclosed are a three-dimensional bag of a non-woven fabric and a processing method. The three-dimensional bag of a non-woven fabric comprises a bag body (1) and handles (2). The bag body (1) is is formed by a front wall (3), a rear wall (4), side walls (5) and a bottom wall (6) by folding a non-woven fabric. The front wall (3) is provided with a front edge (31) by folding. The rear wall (4) is provided with a rear edge (41) by folding. The bottom wall (6) is provided with a bottom edge (61) by folding. The bottom of the front edge (31) and the bottom of the rear edge (41) are fixed to the bottom edge (61) by welding. Weld marks formed by welding the front edge (31), the rear edge (41) and the bottom edge (61) are in an inverted "T" shape. The processing steps are as follows: (1) cutting a non-woven fabric; (2) stamping a notch (12); (3) pressing a "U" shape on the non-woven fabric using the length of the notch (12) as the width of the bottom wall (6); (4) bending the front wall (3) and the rear wall (4) to f
