We were asked about the suitability of “wool mohair” for upholstery.
There’s probably a little confusion here as wool and mohair both refer to animal hair. Technically mohair is wool; as wool encompasses animal hair from the Caprinae family (ie sheep, goats, llamas and rabbits). Assuming that the question means sheep wool then both could be woven together of course. But then the suitability of those fibres for upholstery really depends on how they are woven.
So neither wool nor mohair in themselves are always suitable for upholstery. It depends on how they are woven. To properly assess any fabrics suitability for upholstery you need to look at the fabrics rub test and its ability to be fire treated.
Pure natural fibres (sheep wool and mohair) are normally exempt from the match test for upholstery but still need to pass the cigarette test (please look elsewhere on this blog for information – or for definitive information look at www.textilesfr.co.uk).the fabric may or may no require treating, you will have to check.
Mohair can have a Martindale/rub test of over 100,000 (e.g. our Mohair Velvet) and so can be suitable for contract upholstery. Whereas one of our 100% sheep wool fabrics has a martindale of 23,000 again making it suitable for upholstery.
So really its probably best to find the Mohair/Wool fabric you like and then find out if that particular one is suitable for upholstery.
