Due to the addition of dimethyl phosphite, formaldehyde and tetraethylenepentamine, the organic phosphorus/nitrogen flame retardant can be obtained through Mannich reaction, and when the organic phosphorus/nitrogen flame retardant is used for the polyester fabric, the organic phosphorus/nitrogen flame retardant has a phosphorus-nitrogen synergistic effect, so that the polyester fabric can obtain better flame retardant performance under the condition of small using amount, and has smaller smoke generation amount.
Meanwhile, during combustion, the organic phosphorus/nitrogen flame retardant can generate phosphoric acid, metaphosphoric acid, polymetaphosphoric acid and the like during combustion, so that the surface of the polymer can be carbonized to form a compact carbonized layer, and the polymetaphosphoric acid is sticky molten glass and covers the surface of an unburned material, so that the functions of preventing free radicals from escaping and isolating oxygen are achieved, and the flame retardant effect is achieved.
The flame retardant FRC-1 is matched with the organic phosphorus and nitrogen flame retardant for use, so that the polyester fabric can obtain flame retardant performance with better durability under the condition of smaller consumption of the flame retardant.
Preferably, the softening agent is prepared from the following raw materials in parts by weight:
by adopting the technical scheme, the linear double-end epoxy carbonyl polysiloxane intermediate with high reactivity is synthesized by utilizing the hydrosilylation reaction of hydrogen-terminated dimethyl polysiloxane and glycidyl methacrylate; and then, the modified polysiloxane is synthesized by utilizing the nucleophilic ring-opening reaction of an epoxy group and an amino group between the linear double-end epoxy group carbonyl polysiloxane and diethylenetriamine, so that the softness and the washability of the polyester fabric are further improved, the hydrophilicity and the whiteness value are improved, and the problems that the emulsion of amino silicone oil is unstable, the fabric is poor in hydrophilicity and easy to yellow after the amino silicone oil is used for finishing are solved.
Meanwhile, the condition that partial dimethyl phosphite and formaldehyde are not completely reacted in the flame retardant is inevitable, and the diethylenetriamine can react with the unreacted dimethyl phosphite and formaldehyde to generate the organic phosphorus/nitrogen flame retardant, so that the flame retardant performance of the flame retardant finishing liquid is further improved.
Preferably, the penetrating agent is JFC, and the softening agent: the penetrant JFC is prepared from the following components in a mass ratio of 2: 1.
by adopting the technical scheme, the addition of the penetrating agent JFC has the effect of reducing the surface tension of the flame-retardant finishing liquid and further promoting the flame-retardant finishing liquid to penetrate into the polyester fabric. Meanwhile, the penetrating agent JFC has a synergistic emulsification effect on the softening agent, so that the softening agent forms emulsion in the flame-retardant finishing liquid, the stability of the softening agent in the flame-retardant finishing liquid is further improved, and the softening effect of the softening agent on the polyester fabric is further improved.
Preferably, the flame-retardant finishing liquid also comprises 5-7 parts by weight of carbohydrazide.

Preferably, the flame-retardant finishing liquid is prepared by the following process steps:
preparing disodium hydrogen phosphate, methylated melamine resin and ammonium chloride into a solution, heating the solution, controlling the temperature of the solution to be 50 ℃, sequentially adding a flame retardant, a softening agent and a penetrating agent into the solution, stirring the mixed solution at the stirring speed of 100-150r/min, adding carbohydrazide and a pH regulator into the mixed solution, and regulating the pH value of the mixed solution to be 5-7 to obtain the flame-retardant finishing liquid.

a, soaking and rolling twice, namely soaking the polyester fabric subjected to S3 into the flame-retardant finishing liquid for soaking and rolling twice;
b, drying, namely drying the terylene fabric passing through the A at the drying temperature of 100 ℃ and 110 ℃ for 2-3 min;
c, baking, namely baking the terylene fabric passing through the B, wherein the baking temperature is controlled to be 180-200 ℃, and the baking time is controlled to be 1-2 min;
