    Abstract: A spiral wound-type separation membrane module and a method for manufacturing the same are provided. The spiral wound-type separation membrane module according to an exemplary embodiment of the present invention is implemented by including an outlet pipe; a filter assembly wound in a spiral wound on the outlet pipe; and an adhesion portion in which part or all of a heat-adhesive yarn wound to surround the outer surface of the filter assembly in the longitudinal direction of the outlet pipe is melted and fixed to the filter assembly. According to the above, the spiral wound-type separation membrane module and the method for manufacturing the same can significantly reduce the defect rate and process time and simultaneously exhibit an eco-friendly effect during disposal after use.

    Abstract: The present invention relates to a polyester film for windows, which can block harmful ultraviolet rays from outside or prevent glare from direct sunlight and reduce thermal energy when attached to an exterior wall glass of a building or a vehicle, which can also resolve the phenomenon that an image is blurred or unclear and the image is broken when looking at an external shape through the glass, and in which a clear external shape can be confirmed even through a polyester film because fine roll-drag defects in the longitudinal that could be caused in the manufacturing process of the polyester film are not visible, and the film can be easily shrunk and peeled off even at high temperatures when applying a window film to the glass of a vehicle or a building with the polyester film being laminated with a release film.
