Sažetak
Halogenide free hydroxy-functional organophosphorus oligomer was tested for its possible utilization in the flame retardant (FR) area. This agent was previously applied for the treatment of polyurethane (PU) foams, but not for the finishing of cellulose materials. The advantage of this particular OF compound is its low formaldehyde content which is the main disadvantage of conventional hydroxy- functional organophosphorus agent, still frequently used in FR finishing of textiles. Applied FR agent does not have a functional group that can react with cotton cellulose, so it was necessary to use a bonding agent with the appropriate catalyst – sodium hypophosphite monohydrate (SHP). Through the mechanism of bonding of FR agent, both with the binder and cotton, the flame retarding system is becoming durable to multiple laundering cycles. In this paper evolved gas analysis (EGA) was studied by the coupled TG-IR technique, used for better understanding of the decomposition process and toxicological characterisation. Further investigation of the dehydration and decomposition behaviour of pure cotton and cotton samples treated with two types of flame retardant agents was performed by thermogravimetric analysis (TGA). FR behaviour was tested by limiting oxygen index (LOI) technique, according to ASTM D 2863-08 method.
