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.

The present invention relates to a composite material for a transport, including a polypropylene resin and a carbon long fiber, and more particularly, to a fiber reinforced composite material composition for a transport including 40-90 wt % of a polypropylene resin, 5-60 wt % of a carbon long fiber having a fiber diameter of 1-50 &#x3bc;m and a weight average fiber length of 20-150 mm, and 0.3-10 wt % of a compatibilizer. The compatibilizer includes one selected from the group consisting of an ionomer, a copolymer of propylene-polar monomer, a modification water added polymer and combinations thereof. The composite material has improved interface properties between the polypropylene resin and the carbon long fiber owing to a specific compatibilizer, improved rigidity, impact resistance and heat resistance, and may be applied to various fields requiring the fiber reinforced composite material as well as various transports including an automobile.

The present invention relates to a manufacturing method of a carboxymethyl cellulose nonwoven fabric which includes the carboxymethylation of cellulose fibers and the subsequent paper-making process to prepare a carboxymethyl cellulose nonwoven fabric. Comparing with the conventional method involving carboxymethylation of a nonwoven fabric, the method of the present invention has convenience and easiness of the process and thus enables production on a large scale. Further, the carboxymethyl cellulose nonwoven fabric manufactured by the present invention is susceptible to gelation upon contact with body fluids or water and thus useful as a medical nonwoven fabric or a mask pack.

A multiple fiber spinning apparatus and a method of controlling the same. The apparatus includes an extruding unit, a spin block unit and a spinning nozzle unit. The extruding unit includes extruders that melt, extrude and transfer polymer materials. The spin block unit includes a gear pump unit which has gear pumps connected to each of the extruders. The gear pumps receive the polymer materials from the corresponding extruders and discharge the polymer materials. The spin block unit further includes a flow passage unit which has flow passages connected to the respective gear pumps. The spinning nozzle unit includes spinning nozzles, each of which is connected to one of the gear pumps of each extruder by the corresponding flow passage, so that each spinning nozzle receives the molten polymer materials and spins the polymer materials into a fiber.

Multiple fiber spinning apparatus and method for controlling same
