    Abstract: The present invention relates to a medical nonwoven fabric comprising gelable cellulose derivative short-cut fibers as prepared by the paper making process, a preparation method thereof, and an adhesion prevention barrier using the same. The present invention provides a single phase of medical nonwoven fabric comprising gelable cellulose derivative short-cut fibers, to induce capillary action of micropores formed between the fibers and thereby control the gelation time, and provides a composite nonwoven fabric formed by laminating a nonwoven fabric layer comprising a different kind of biodegradable polymer material not susceptible to gelation on the single-phase of medical nonwoven fabric comprising gelable cellulose derivative short-cut fibers, thereby improving dimensional stability and convenience of surgical procedure. The present invention further provides a dyed medical nonwoven fabric to improve visibility, allowing easiness of recognizing the placement or location of the medical nonwoven fabric. Further, the single-phase nonwoven fabric or the composite nonwoven fabric, which makes it possible to efficiently control the gelation time by way of capillary action of the micropores formed between the fiber in the nonwoven fabric, can also be used as an adhesion prevention barrier with improved convenience of surgical procedure and post-surgical adhesion, in contrast to the conventional knit or film type adhesion prevention barrier.

    Abstract translation: 本发明涉及一种医用无纺布，其包括通过造纸工艺制备的可胶化纤维素衍生物短切纤维，其制备方法和使用其的防粘连屏障。 本发明提供一种包含可胶化纤维素衍生物短切纤维的医用非织造布的单相，以诱导在纤维之间形成的微孔的毛细作用，从而控制凝胶化时间，并提供通过层压非织造织物层 包括在包含可胶化纤维素衍生物短切纤维的医用无纺织物的单相上不易凝胶化的不同类型的可生物降解聚合物材料，从而提高尺寸稳定性和手术方法的便利性。 本发明还提供一种染色医用无纺布，以提高可视性，容易识别医用无纺布的放置位置。 此外，通过无纺布中的纤维之间形成的微孔的毛细作用有效地控制凝胶化时间的单相无纺布或复合无纺布也可以用作粘合防止屏障 与传统的针织或膜型粘附防止屏障相比，具有改善的外科手术和手术后粘连的便利性。
