Application of flame retardant microcapsules to polyester and cotton fabrics

A microcapsulated fire retardant was used with the intention to produce fire retardant textiles. Melamine-formaldehyde polymer-wall microcapsules with triphenyl phosphate core were applied both a cotton woven and a polyester nonwoven fabric using impregnation and screen printing. The samples were observed with a scanning electron microscope (SEM). The combustion performance of the textile samples was examined with the limiting oxygen index (LOI) and the vertical burning test. The thermal properties of the microcapsules and fabrics were examined using TGA and DSC analyses.The mass per unit area, rigidity and air permeability of the treated fabrics were tested. The results show that the microcapsules with triphenyl phosphate can be sucessfully applied to cotton and polyester fabrics using screen printing and impregnation methods, but the fire retardantion was sucessful only at the highest concentration of the microcapsules. Atthis concentration, the mechanical properties of the starting material appear to deteriorate.
