Production method for nylon 6DTY slub yarn

The invention provides a production method for a nylon 6DTY slub yarn. The production method comprises the steps of successively penetrating a POY yarn through a raw filament frame, a first roller, atwist-stop device, a deformation heat box, a cooling plate, a false twister and a second roller in elasticizing equipment to obtain a strand with a draw ratio of 1.1; the nylon 6DTY slub yarn is obtained after processing by a shaping hot box, a filament sucking device, an oil roller and a winding head; the temperature range of the deformation heat box is 180 DEG C-200 DEG C, the setting temperature range is 190 DEG C-230 DEG C, and the ratio of the surface speed of a friction disc of the false twister to the speed of the strand leaving away from the false twister is controlled within 1.6-1.9.The production method can obtain the high-quality slub yarn through process improvement of original elasticizing equipment. 本发明提供种锦纶6DTY竹节纱的生产方法，包括：采用POY纱线依次经过加弹设备中的原丝架、第罗拉、止捻器、变形热箱、冷却板、假捻器和第二罗拉得到拉伸倍数为1.1的丝条；之后再经过定型热箱、吸丝器、油辊和卷
