[0062] (3) Preparation of stearyl citrate: citric acid and stearyl alcohol are mixed and reacted to obtain stearyl citrate;

[0063] (4) soaking the dyed polyester into the stearyl citrate solution, after the treatment, the dyed polyester is taken out, extruded and kept at a certain liquid retention rate, and dried to obtain the dyed polyester intercalated with the stearyl citrate;

[0064] (5) Soak the dyed polyester intercalated with stearyl citrate in a solution of phosphoric acid and urea to react, and obtain the dyed flame-retardant and anti-dripping polyester.

Embodiment 1

[0069] Example 1 A kind of flame-retardant anti-dripping polyester based on copper chlorophyllin sodium salt dyeing

[0070] The preparation method of the flame-retardant anti-droplet polyester dyed based on sodium copper chlorophyllin comprises the following steps:

[0071] (1) Fiber dyeing: first weigh the quality of the polyester, and then calculate the volume of the dyeing solution based on the bath ratio of 1:10. The concentration of sodium copper chlorophyllin in the dyeing solution is 5g / L, and the fiber is placed in the prepared dyeing solution water bath at 60°C and fully dyed for 0.5h;

[0072] (2) Squeeze the fibers obtained through the treatment in step (1) to remove excess solution to make the liquid retention rate 30%, then dry at 60°C for 0.5h to obtain dyed polyester;

[0073] (3) Preparation of stearyl citrate: mix citric acid and stearyl alcohol in a molar ratio of 1:1, and react at 120°C for 0.5h to obtain stearyl citrate;

Abstract

The invention provides flame-retardant anti-dripping polyester as well as a preparation method and application thereof. The flame-retardant anti-dripping polyester provided by the invention is obtained by dyeing polyester with a porphyrin structure compound, performing ester intercalation and then performing ammonium salt modification. The preparation method of the flame-retardant anti-dripping polyester provided by the invention is simple and convenient and low in cost, the polyester has durable flame-retardant anti-dripping performance on the basis of ensuring the fiber strength and fiber color fastness, and the prepared polyester has excellent flame-retardant anti-dripping and thermal stability, and is suitable for industrial production. The harm to the environment and the physical property of the fiber caused by the addition of the flame retardant can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a flame-retardant and droplet-resistant polyester as well as its preparation method and application. Background technique [0002] Polyethylene terephthalate (PET) fiber, that is, polyester, is the largest synthetic fiber in the world. It has excellent mechanical properties, wear resistance, and good chemical stability. It occupies an important position in the textile industry. important position. However, the limiting oxygen index (LOI) value of polyester is about 20%, which is one of the more flammable fibers. At the same time, the burning process is accompanied by serious droplet phenomenon, and the resulting droplet is very easy to ignite other items. , exacerbated the hazards caused by the fire. Therefore, it is of great significance to improve the flame retardant and anti-droplet properties of polyester. At present, commercialized flame-retardant polyester mainly adopts...
