An embodiment of the invention discloses a complete-extinction thin and light meshy polyamide fiber 6 draw textured yarn (DTY) manufacture method. The method comprises the following steps of (a) fusion and high-speed spinning, (b) lateral blowing and cooling, (c) oil coating and beam concentration, (d) winding, (e) fiber guiding and heating, (f) cooling and false twisting, (g) drafting, and finally complete-extinction thin and light meshy polyamide fiber 6 DTY is obtained. By adjusting selection of a spinneret plate, the spinning temperature, cooling conditions, spinning speed, oil coating rate, winding speed and the like, the problems including much floating fiber, multiple broken ends and low full barrel rate in the complete extinction thin and light meshy polyamide fiber 6 DTY production process, uneven filling power, poor mesh evenness, much rigor-point broken filament and low in strength of post-processed yarns are solved, the product production quality is stable, and the rate of finished products is high.
