Suitability of Wool Mohair For Upholstery

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.

UK & European Fire Treatment For Interior Fabrics

Without exception, no fabric company can self-certify the fire retardancy of their fabrics. That can only be undertaken by a UKAS Accredited Test Laboratory. The following is KOTHEA’s summary of Textiles FR’s document “The Flame Retardancy Of Textiles” and, for detailed advice on the exact current legislative requirements, the reader should consult Textiles FR on 01274 651230.

1. Domestic

a. Curtains – No treatment is required.
b. Upholstery – The fabric must be treated to reach the match test (BS5852: Part1: 1979: Source 1).
The designer must first check the fabric passes the cigarette test (BS5852: Part1: 1979: Source 0).

Note:
The cigarette test meets the equivalent European standard BS EN 1021-1.
The match test meets the equivalent European standard BS EN 1021-2.
Fabrics containing 75% mixed-natural or natural fibre content do not usually require treating as they normally pass ‘the cigarette test’. You must use a Schedule 3 interliner (fire retardant to CRiB 5) though.

2. Contract

a. Curtains – The fabric must be treated to BS5867: Part 2: Type B.
Some fabrics meet this standard naturally, most do not. Some fabrics cannot be treated for this standard.
b. Upholstery – The fabric must be treated to BS5852: 1990: Source 5 (CRiB 5).
This involves the fabric being back coated and most fabrics can be treated in this way.

Note:
BS7176 covers BS5852: 1990. And BS5852: 1990 covers BS5852: Part 1: 1979 and BS 5852: Part 2: 1982. So the info above in 2b is correct. This treatment meets European standards.

3. Other Uses
Headboards, bed covers, wall coverings, yachting and aviation may have differing requirements.

There is a broad equivalence of British and European standards. However, the standards for the USA are different from Europe.
