摘要： 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.
