Non-sewn down bedding and manufacturing method thereof

A non-sewn down bedding item comprising:

• a bedding outer cover having an upper fabric and a lower fabric, the upper fabric and the lower fabric defining an inner space;
• a partition wall member configured to divide the inner space into a plurality of compartment spaces such that each of the compartment spaces is filled with down, the partition wall allowing air to flow between the compartment spaces and restricting movement of the down between the compartment spaces;
• and
• an edge finish portion formed at an edge of the bedding item to inhibit the down from escaping from each of the compartment spaces,
• wherein the partition wall member comprises:
• first and second single-sided adhesive tapes (31a, 31b) respectively sewn to both longitudinal edges of a mesh strip having a width W allowing air to pass therethrough and inhibiting the down from passing therethrough, the first and second single-sided adhesive tapes each having a width of less than half the width W;
• and
• a mesh strip portion folded by a hot press along a longitudinal center line (35) of the mesh strip (29) in a longitudinal direction so as to have a substantial width We less than the width W of the mesh strip and remaining not bonded to the single-sided adhesive tapes (31a, 31b),
• wherein adhesive surfaces (33a, 33b) of the single-sided adhesive tapes (31a, 31b) sewn to the mesh strip (29) folded by the hot press in the longitudinal direction face away from the mesh strip (29) so as to be attached to the upper fabric and the lower fabric, respectively,
• wherein the edge finish portion comprises:
• a thermally melting reinforcing tape (39) interposed between and attached to the upper fabric and the lower fabric by being heated by a press;
• and
• a liner (41) sewn by wrapping outer surfaces of the upper fabric and the lower fabric, with margins (43a, 43b) being formed by folding longitudinal opposite sides of the upper fabric and the lower fabric inward, the margins (43a, 43b) contacting the upper fabric and the lower fabric.
