Abstract
In the flame-retardant treatment of fabrics, there is provided a means for increased 'loading' of phosphorus compounds (up to 25% moisture is retained after impregnation and drying of the fabric). This in turn enables a phosphonium compound 'add-on' of 50% to 73% (relative to the weight of the fabric) and gives a correspondingly higher degree of flame-retardant properties.
