Hairs and Fibres

RSSL's microscopy department uses a combination of light microscopy and FT-IR techniques to:

• Distinguish between natural and man-made fibres

• Identify the man-made fibre types

• Identify the animal origin of hair

• Suggest a route for the contamination

Hairs and fibres can originate from a number of sources including sacking, ropes, contaminated raw ingredients, factory dust, infestation, personnel and packaging.
