This method describes a procedure for the quantitative analysis
of binary mixtures of nylon 6 or nylon 6,6 with cotton, wool and
regenerated cellulose fibres (regular viscose, high-tenacity
viscose and high-wet-modulus rayon (modal)) by removal of the
nylon 6 or nylon 6,6 component. The method is intended only for
mixtures of fibres that have not suffered marked chemical
degradation.
