The invention discloses a nylon flame-retardant infrared-resistant camouflage braid production process which comprises the following steps: spinning, braid weaving, braid washing, ground color dyeing, printing, high-temperature color development, post-treatment and flame-retardant treatment. The invention has the beneficial effects that: 1, the cross section of the monofilament ejected from the spinneret orifice is Y-shaped by transforming the spinneret orifice, so that the surface brightness of the monofilament is increased, and the reflective refraction of the surface of a nylon braid woven by nylon yarns consisting of the monofilament is improved, and the color and luster of the nylon braid are saturated; 2, the spinning temperature of a spinning melt is increased, the content of cooling master batches is increased, the stretching ratio is increased, the softness of monofilaments is improved, the monofilaments can be tightly cohered together without being dispersed after being fully stretched, and therefore the nylon yarn is not prone to fuzzing; and 3, the air pressure during padding is improved, and the stability of the pressure is ensured, so that the nylon braid is fully padded, the moisture content of the nylon braid during secondary dip dyeing is consistent, and the dyeing uniformity of the nylon braid is improved.
