[0017] The filter for extracting and extraction bag consisting of homo-polyester fibers, is poor fusion due to the bag-making at the time of ultrasonic sealing method, or a heat-sealing method. One of the causes that have not been used so far in this field is that sufficient delamination strength of the fused surface cannot be obtained. However, if the sheath component is a polyester-based fibers of core-sheath double structure is a low-melting component have either soft, heat-sealing method and ultrasonic sealing method is applicable delamination strength is significantly improved . In particular, it has been found that the delamination strength by the ultrasonic sealing method is remarkably improved, and that the delamination strength is almost the same as that of conventional nylon. Meanwhile, when the extraction buffer <br/> grayed in polyester fiber having a core-sheath double structure in the present invention method, string that suspends the bus Tsu grayed, a sealing property of the tag is good, even extracts It has excellent adhesiveness with supporting members (laminated paper, plastics, etc.) that attach the bag for beverage to the beverage container.
