The invention discloses a fixed-guiding non-woven fabric production method. The method comprises the following steps: preparing raw material used for non-woven fabric; heating and melting polylactide and polypropylene to obtain melts; adding photosensitizers, ammonium polyphosphates, fillers, antibacterial agents and titanate coupling agents into melts, stirring and mixing uniformly, spraying through spinneret holes and carrying out cooling solidification to form fibers; crossly arraying fibers in horizontal-vertical directions and forming a fiber net through carding; adjusting flatness of the fiber net and conveying the net into a hot milling machine for hot-press formation and finally performing trimming and examination. The fixed-guiding non-woven fabric production method has the following beneficial effects: raw material is safe and eco-friendly; the production method is easy; a production condition is mild; a product is good in formability, low in prediction cost and suitable for industrialized production; non-woven fabric is featured by being small in thickness, low in weight, good in tenacity and anti-moisture, breathable and tear-resistant; by adding ammonium polyphosphate, fillers and antibacterial agents, the non-woven fabric is antibacterial, flame-retardant, dustproof and biodegradable and worthy of promotion.
