High-strength chinlon 6 fiber and production method thereof

The invention discloses a high-strength chinlon 6 fiber and a production method thereof.The production method comprises the steps that polyamide 6 dry slices are conveyed into a screw extruder through a pipeline to be subjected to melting, mixing, compression and extrusion treatment, then polyamide 6 melt is obtained, then the polyamide 6 melt is accurately metered through a melt metering pump and filtered through a spinning assembly, and the polyamide 6 fiber is obtained. The preparation method comprises the following steps: preparing a polyamide 6 fiber bundle, extruding through spinneret micropores of a spinneret plate to obtain the polyamide 6 fiber bundle, sequentially carrying out side blowing cooling, bundling and oiling, stretching and sizing and network interlacing on the polyamide 6 fiber bundle, and winding and forming a product to finish production. According to the scheme, when chinlon 6 is produced, the polyamide 6 fiber tows are ingeniously stretched and shaped at a specific temperature, and th
