Abstract

A mesh fabric funnel-shaped bag, and a production method for garment dyeing using the mesh fabric funnel-shaped bag. The mesh fabric funnel-shaped bag is fixed on a mesh fabric, and comprises at least one mesh fabric funnel-shaped bag unit. The mesh fabric funnel-shaped bag unit is funnel-shaped. The mesh fabric funnel-shaped bag unit has one wide opening and one narrow opening in the length direction. The diameter of the mesh fabric funnel-shaped bag progressively decreases from the wide opening to the narrow opening. The mesh fabric funnel-shaped bag can be sewn on the mesh fabric, and part of the mesh fabric funnel-shaped bag at the narrow opening floats out and is separated from the mesh fabric. The beneficial effects are that: since part of the mesh fabric funnel-shaped bag at the narrow opening floats out and is separated from the mesh fabric, a corner is formed after a garment is put in, and thus resistance is produced; moreover, since the diameter of the mesh fabric funnel-shaped bag progressively decreases from the wide opening to the narrow opening, resistance is produced when the garment moves to the wide opening; thus, the garment is prevented from coming out of the mesh fabric funnel-shaped bag during dyeing.
