Abstract:

Aiming at the potential safety hazard caused by the flammability of viscose fibers, phosphonitrilic chloride trimer containing a ring structure was selected as a functional monomer to design a star-shaped halogen-free flame retardant that combines phosphorus, nitrogen, silicon ternary flame retardant elements. The flame retardant was added to the viscose, and then the flame retardant modified viscose fibers was prepared through wetting spinning. The structures and properties of the modified viscose fibers were characterized by means of Fourier infrared spectroscopy, X-ray photoelectron spectroscopy, thermogravimetric analyzer, and thermogravimetric-mass spectrometry system. The results show that the flame retardancy of the modified viscose fibers was improved while the fibers maintaining the durability. In nitrogen atmosphere, its char residue rate at 800 ℃ increased from 12.5% to 31.2% compared with the unmodified viscose fibers. During the combustion process of the modified fibers, the release of combustible gas was significantly reduced and abundant expanded carbon layer was produced. The flame retardant operated in condensed phase and gas phase.

Key words: viscose fiber, blending modification, wetting spinning, flame retardant, phosphonitrilic chloride trimer, thermal stability, flame retardant mechanism
