【発明の名称】アラミド類が示す可燃度を下げる方法
Document Type and Number:
Japanese Patent JPH08507565
Kind Code:
A
Abstract:
Disclosed herein is a process for reducing the flammability of aramids by contacting a solvent swollen or never dried aramid with an aqueous solution of a tungsten compound, removing the solvent from, and then drying the aramid. The resulting aramids have superior Limiting Oxygen Indices, making them particularly useful where lower flammability is desired, as in firefighters' overcoats.
