Scope

This document specifies a qualitative and quantitative method for determining the
components of animal hair fibre mixtures in textiles using matrix-assisted laser
desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).
Non-animal hair fibre components can be tested according to GB/T 2910 (all parts),
and the results can be combined to determine the overall fibre content.
This method, following FZ/T 01057.3, uses an optical microscope to observe the
morphology of mixed fibres for preliminary identification. This method is not
applicable to situations where animal fibres of the same species coexist (e.g., a mixture
of cashmere and mohair). Such samples can be analyzed and quantified using
microscopic methods (e.g., the analytical methods described in GB/T 40905.1 and
GB/T 40905.2).
