Flame retardants lack chemical bonding with fiber-forming polymer macromolecules, resulting in poor durability, and the feel and strength are also affected, greatly reducing its wear performance. The reason is that flame retardants have poor dispersibility in the product, making it difficult to mix evenly with the melt, and are easily released during spinning, causing spinning difficulties, affecting the flame retardant effect of the product and the physical properties of spinning. To this end, researchers have conducted various experimental studies on the dispersion of flame retardant materials and fiber finishing.

APG can replace the surfactant components in traditional detergents (AES, LAS, AEO, 6501), and can also be used in combination with them for processing, with an ideal synergistic composite effect.

After APG is compounded in washing powder, the mildness, hard water resistance and comprehensive decontamination ability of washing powder can be significantly improved.

APG is added to the solution before viscose fiber spinning as a dispersant for flame retardant materials, and the macromolecular groups in the viscose fiber mother liquor are used to copolymerize and crosslink with the flame retardant material molecules and APG active groups. They are nested in the spinning process to form a cross-linked network, thereby increasing the bonding between molecular chains, changing the internal structure of viscose fiber, and increasing the crystallization area of viscose fiber, thereby improving its mechanical strength and flexibility.

1) Add the flame retardant material directly to the spinning mother liquor at a mass fraction of 2%~5% glue solution, stir it to make it uniform, put it into a container, and vacuum it for defoaming treatment for 50min~60min; use an acidic coagulation bath for spinning, plasticization and stretching; wash the filaments with 40℃~45℃ water twice, and use NaOH for desulfurization treatment, the amount is 3%~10% of the sample weight, the temperature is 40℃~45℃; wash the desulfurized filaments with 40℃~45℃ water twice, dry them, and cut them into 51mm lengths as conventional flame retardant viscose fibers for standby use.

2) Prepare a dispersion of flame retardant material with APG as dispersant and stir it homogeneously. Add 2% to 5% of the glue mass fraction into the spinning mother solution, stir it to make it uniform, put it into a container and evacuate it for defoaming treatment. The treatment method and process are the same as above.
