Abstract

The invention relates to an anti-dripping flame-retardant finishing method for high-tenacity polyester, which comprises the following steps: adding a compound flame retardant, an adhesive and an anti-dripping agent into a solvent at 100-160 DEG C, and stirring to obtain a flame-retardant solution; and adding polyester fabrics into the flame-retardant solution for soaking and rolling twice respectively, then pre-baking at 80-120 DEG C for 3-6min, baking at 140-180 DEG C for 2-4min, taking out, and cooling to obtain the high-tenacity polyester. The polyester fabrics finished by the finishing process provided by the invention have the characteristics of flame resistance, smoke suppression, high tenacity and anti-dripping capability so as to meet the high-tenacity requirement for polyester and have broad market prospects. The polyester fabrics obtained by the finishing method provided by the invention have the tenacity of 6.6-8.0cN / dtex, the limited oxygen index of 28-40% and the breaking elongation of 13-16%.

Description

technical field [0001] The invention belongs to the field of polyester finishing methods, and in particular relates to a high-strength polyester finishing method with anti-melt drop and flame retardancy. Background technique [0002] Polyester textiles have been widely used in clothing, curtains, curtains, bedding, interior decoration and various special materials, while the limiting oxygen index (LOL) of polyester fiber is only about 22%, which is a combustible fiber and will cause serious damage when burning. The phenomenon of molten dripping. These high-temperature droplets can easily ignite other polymer materials, accelerate the spread of flames, and expand the scale of the fire. If the molten material sticks to the skin, it will cause skin burns; in addition, the latent heat released when the molten polymer re-solidifies will also cause skin damage, and removing the solidified polymer that sticks to the skin will increase the damage to the skin degree. Therefore, ho...
