Fabric Composition

NIR is an excellent technique for identifying the composition of fabrics.

If you enter the search term "How to find out what a fabric is made from" then you're likely to find references to 'burn tests', such as this one. Fabric burn tests involve taking a small sample of the fabric and holding it over a naked flame, to observe whether it shrinks, melts or burns – and noting the resulting smell. Not surprisingly, you'll also be advised to have a fire extinguisher to hand, and not to let children do these tests.

Now there's a much simpler, safer and more accurate method to determine the composition of fabrics, using miniature NIR spectroscopy. One that will give you an answer within a few seconds, right there in the fabric or garment store.




To demonstrate the versatility of miniature NIR spectroscopy, Sagitto has created a model to measure the composition of fabrics. This can be used by anyone with access to either the Sagitto spectrometer, or the DLP® NIRscan™ Nano EVM evaluation module.

Each fabric has a distinctive NIR absorbance fingerprint, based on its fibre composition
