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.
If the types of fibres present in the mixtures are not known, they must be identified before quantitative analysis can be undertaken (par 10.1).
The accuracy of the results obtained with this method will be decreased by the presence of nonfibrous finishes that cannot be removed.
This method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any existing applicable regulatory requirements prior to its use.
