Abstract

The woven bag DC60 will feature a woven sheet (2), with two front and back woven layers (21,22) facing each other in opposite directions, interconnected at the left and right ends (201,202) and Which respectively have the top end (20) and the lower end (25) adjacent and the seam (23) which extends in the left-right direction and passes through the lower end (25). The suture (30) has front and back hem (31), which are bonded to the front and back surfaces of the lower ends (25) in a hermetically and respectively manner. And which have left and right overhangs (311) extending beyond the left and right ends (201,202) of the lower ends (25), the front and back sutures (31) are bonded together in a sealed manner. Tightly held in the left and right overhang (311), which is the left and right (201,202) seal of the lower end (25), the woven bag has a woven sheet part (2) with a woven layer on the front and back. (21,22), two layers facing each other in opposite directions, connected at the left and right ends (201,202) and, respectively, the top end (20) and the lower end (25), which are adjacent. Together and the seam line (23), which extends in the left-right direction and passes through the lower end (25), the suture assembly (30) has front and back seams (31), which are bonded to The front and back surfaces of the lower ends (25) in a hermetically sealed manner and respectively And which have the left and right overhangs (311) that extend beyond the left and right ends (201,202) of the lower ends (25), the front and back sutures (31) are bonded together in a hermetic manner. In the left and right overhang (311), which is the left and right (201,202) seals of the lower ends (25).
