FIRE-PROOF PROCESSING METHOD FOR SYNTHETIC FIBER

摘要

PURPOSE:To raise the adsorbability of a fire-proof agent and improve the fire retardancy of a synthetic fiber in a small amount of the fire-proof agent by treating the synthetic fiber or a composite material thereof with both hexabromocyclododecane and a specific phosphate compound. CONSTITUTION:A synthetic fiber such as polyester fiber or a composite material thereof with a cellulose fiber is treated with an emulsified fire-proof agent comprising hexabromocyclododecane and a phosphate ester of the formula [a, b and c are 0-3, a+b+c=3; A is C6H5, B is C6H4-CH3 or C6H3-(CH3)2; C is C8H17, CH2CH2Cl or CH-(CH2Cl2)2] in a weight ratio of 10:0.5-30 to improve the fire retardancy of the fiber or composite material in a small amount of the agent. The simultaneous treatment of the fiber with both the processing agent and a dye in a dyeing bath permits the improvement of the adsorption of the processing agent at a low temperature of <=120 deg.C and simultaneously permits the dyeing treatment of the fiber.
