    配制方法: the liquor is applied to the fabric by padding, and any surplus is expressed by adjustment of the nip to give a desired wet "add-on" which is a direct function of the final dry "add-on". The treated fabric is then dried, and cured at 120-140'c for 2-4 min. Washing and treatment with an appropriate softening agent may then be carried out if necessary in conventional plant used for this purpose.
    In special circumstances the emulsion may be applied by brush or spray.
    For example, the hessian backing of a carpet can be flameproofed after manufacture by spraying or brushing the emulsion on to the reverse side, subsequently drying and curing. However applied, the emulsion is absorbed by the fibres, and thus a continuous surface coating of the fibre is formed.
