Polyester flame retardant silk do you really understand?

Polyester flame retardant silk is a modified polyester fiber with flame retardant properties, which has important applications in many fields. The following is a detailed introduction about it:

Production method

Copolymerized flame retardant modification: In the polymerization process, the use of such as tetrabromobisphenol a hydroxyethyl ether or phosphorus compounds as a copolymer, with dimethyl terephthalate and ethylene glycol through transesterification and condensation reaction to prepare the copolymer, and then through melt spinning, stretching and other processes to obtain flame retardant polyester yarn.

Blended flame retardant modification: adding phosphorus-containing compounds or halogen-antimony composite flame retardants to the spinning melt, and then melt spinning and stretching to prepare; Composite spinning components can also be used, adding flame retardants in the core layer, and the cortex is ordinary polyester. This method is relatively simple, and can reduce the impact on fiber properties while improving flame retardancy and flame retardancy durability.

Flame retardant finish: The use of alene monomers containing phosphorus or halogens, surface polymerization, graft copolymerization or the use of nitrile treatment on the fiber or fabric, so that the polyester fiber to obtain flame retardant properties.

Performance characteristics

Good flame retardant: This is the core feature of Polyester flame retardant silk. Its limiting oxygen index is usually between 26-34, which can effectively reduce the burning rate of the material, delay the spread of the flame, and quickly self-extinguish after leaving the fire source, greatly improving the safety during use.

Excellent physical properties: most of the physical and mechanical properties, appearance and post-processing properties of flame retardant polyester are similar to ordinary polyester, such as high strength, good elasticity, wear resistance and corrosion resistance, does not affect the normal textile processing and use.

Good dyeing performance: Because the structure of flame retardant fiber is loose, dye molecules are easy to enter, so the dyeing speed is faster than ordinary polyester, and can be used to disperse dyes or cationic dyes dyeing, to meet the needs of different colors.
