The present invention relates to a method for producing a fire retardant material using a natural cotton wool. Natural cotton wool is dipped in a solution having 3-6 wt% of a reactive flame retardant agent, and temperature of 100-150°C is maintained in a high pressure part, so the natural cotton wool is reacted for 30-40 minutes and the natural cotton wool made to be fire retardant is taken out to be dehydrated and dried. Accordingly, cotton wool firstly made to be fire retardant is obtained. In 4-8 wt% of a solution of a secondary fire retardant composition including an additive fire retardant agent, a solubilizer, a dispersing agent, a mycostat, a water repelling agent, and a silane coupling agent, the cotton wool firstly made to be fire retardant is dipped and agitated at room temperature for 20-30 minutes. Then, a dipped solution is adjusted to be acid or alkali neutral, and cotton wool secondly made to be fire retardant is taken out and dehydrated. Cotton wool dried to have a moisture content of 7% is modified and beaten to be made into a nonwoven fabric shape. |
