Cheese dyeing method and used sealing tapered end

The invention relates to a cheese dyeing method and a used sealing tapered end, and belongs to the field of weave dyeing and finishing technology. The sealing tapered end comprises a pressing device, a sealing device and a sealing member. The pressing device comprises a pressing board, a support column, an elastic member and a connecting member. The pressing board and the connecting member are respectively provided with a first through hole and a second through hole matching the support column, one end of the support column is fixed in the first through hole, the other end is inserted in the second through hole, and the elastic member is sleeved on the support column. The sealing device comprises a surface disc, a bobbin contact member and a yarn rod contact member which are coaxially fixed. The sealing member comprises a first seal ring arranged between the connecting member and the support column, a second seal ring sleeved on the outer wall of the bobbin contact member, and a third seal ring arranged in the inner wall of the yarn rod contact member. The sealing tapered end is excellent in current sealing effect, the effective flow proportion can be increased, and the ineffective flow proportion can be reduced, the dyeing quality can be improved, and the energy consumption can be saved.
