This invention relates to a method for preparing low-pore-count, high-cohesion, and high-strength nylon 6: Nylon 6 chips with a moisture content of 350-450 ppm are extruded through a screw extruder and quantitatively conveyed to a spinning assembly by a metering pump to form fibers. The radial cross-section of the fibers has several hooks spaced along the circumferential direction. The extruded fibers are sequentially fed into a slow cooler and a monomer suction device, and then uniformly cooled by side blowing to form filament bundles. The filament bundles are fed into a spinning bundle strengthening oiling device with an oil nozzle, guide hooks, and a blower bundle, allowing several filament bundles to be oiled by the oil nozzles and their corresponding guide hooks. Finally, the several filament bundles enter the blower bundle together and are hooked together by compressed air. The oiled and bundled filament bundles are sent to a pre-networker to blow the oil agent evenly onto the filament bundles, and then stretched and heated by a first and second roller, and disturbed by a main networker. After the spinning tension is adjusted by a guide disc, the filament bundles are wound into a filament cake at the winding head. The high-strength nylon 6 filament bundles prepared by this method have strong cohesion and are not easily separated under external force. When woven into fabric, they can play a very good anti-snagging role.
