摘要： Provided herein is a flame retardant agent that is useful for treating kapok-fiber or kapok-nonwoven fabric. Kapok-fiber or kapok-nonwoven fabric when treated with the flame retardant agent is capable of reducing the impact of fire and providing flame retardancy. The flame retardant treated kapok-fiber or kapok-nonwoven fabric has desired properties including acid resistance, light resistance, absence of stickiness, and absence of a glaucous appearance. Thus, the flame retardant treating agent is suitable for use with materials used in vehicles, clothes, bedclothes, and the like.
