Zusammenfassung:	The invention relates to a method for preparing high-tenacity low-elongation polyamide 6 fibers. The method for preparing high-tenacity low-elongation polyamide 6 fibers comprises the following steps of: 1) fusion: sliding pre-dried polyamide 6 and performing fusion to obtain spinning solution; 2) spinning: performing spinning by enabling the spinning solution to enter a spinning component, wherein monofilaments are sprayed out from a spinneret plate; 3) bundling and oiling: bundling the monofilaments reaching a bundling and oiling point and oiling the surface of a bundle, wherein spinning oil contains polyamide chain extender and ultraviolet screening agent; 4)hot drawing: enabling oiled bundle to sequentially pass through No.1 combined rollers, No.2 combined rollers and No.3 combined rollers to perform hot drawing; 5) winding: enabling the bundle after hot drawing to pass through a separate interlacer and winding at a winding head to obtain high-tenacity low-elongation polyamide 6 fibers. The polyamide 6 fi
