The invention relates to a method for preparing durable flame retardant cotton fabrics, which comprises the following steps: firstly, preparation of a finishing liquid, namely amino-methylphosphonate DAMP, a silane coupling agent gamma-glycidyl oxyl propyl trimethyl silicane and running water are uniformly mixed, and the pH value of the mixture is adjusted to between 3 and 7 by a finishing liquid pH regulator to obtain the finishing liquid; secondly, flame retardant finishing of the cotton fabrics, namely the cotton fabrics are immersed into the finishing liquid for 20 minutes at a temperature of 40 DEG C, padded until the liquid rate is between 75 and 80 percent, dried for 3 minutes at a temperature of between 80 and 100 DEG C, and roasted for 3 minutes at a temperature of between 150 and 180 DEG C; and thirdly, testing of the flame retardant property and the durability of the cotton fabrics after finishing. The method for preparing the flame retardant cotton fabrics has the advantages that raw materials have wide sources; the prepared cotton fabrics have good durability and flame retardant property; and the method has small influence on physical and mechanical properties of the cotton fabrics.
