Not Sure if it should go here or in the kit section...

A little tale of a flame and a warning.

I've used Ventile smocks going back to my ex RAF days, and others I've known have used Ventile garments of one kind or another, one feature that we all like is that unlike synthetics around a fire and embers Ventile smoulders and can be put out quickly with only a minor ember mark or hole rather than melting or igniting like synthetics are prone too.

With this in mind and other considerations I had a double layer classic smock made by Snowsled at a cost of £300, last weekend was my 2nd outing with out, standing near the fire an ember landed on my smock it and unlike Ventile garments I've had before it actually ignited just as a synthetic material would burning a 5p hole in the double layer of material in the space of a few seconds.

A friend was with me at the time and we both quite surprised at how quickly it went up.

I phoned Snowlsed who seemed a little defensive and stumped - I asked if the jacket had been treated with a proofing compound as the smock tended to bead with water rather than soak and swell as previous Ventile garments I've owned have. I didn't get an answer regarding the smock being proofed. But was told that if I would send it in they would look at it for me.

It went back to Snowsled, having spoken to them they made the point several times that Ventile is a cotton material and isn't fire proof and seemed to miss the point that I had made in the covering letter that in my experience of Ventile it doesn't rapidly ignite with flame but smoulders - this experience is echoed by Les who I work with and help run bushcraft courses with and students who have bought Ventile smocks on our recommendation.

It did come up that the material was treated with a fluorocarbon compound by Ventile Fabrics and that it was not their problem. I was quoted £20 for repair as it is (being close to the zip) apparently a 'difficult' repair. Needless to say not impressed but I've asked for it to be repaired anyway.

I did contact Mark at Ventile Fabrics to discuss the 'coating' that Snowsled tells me that Ventile Fabrics apply. He was keen to stress that it isn't a coating and that the material is impregnated with this compound. He was quite concerned at what I described and said that if I could give him a week he would contact the dye manufacturer, the fluorocarbon compound manufacturer to ask if they had any changes in process and would also track down a sample of the batch he supplied to Snowsled for testing and come back to me.

So in terms of customer service a big thumbs down to Snowsled, they certainly will not be getting my business again, nor will I be recommending them to any of our students. By contrast Ventile Fabrics deserve a thumbs up mention for at least listening and trying to find out what might have caused this.

Something that did come out of the various conversations was that the impregnation does wear down with a 3-4 good soakings and some wearing of the garment.

If I might suggest that if you have recently bought a Ventile garment make sure it gets some very good soakings before getting close to a fire with it.

As an aside Mark did mention that Ventile is available in a FR (Fire Retardant) version, made for the MoD.

Sorry your smock's damaged, but that's useful information on the ventile.
Thanks for taking the trouble to write it out and let us know.

I'm sure I'm not the only one who'd like to hear what the Ventile Fabrics company feedback is too.

As a sort of aside; anyone know why waxed jackets don't burn with sparks ? Well, mine hasn't so far and it's been used near fires for years. The wax is surely paraffin wax that's heated and melted into the cotton.

cheers,
Toddy

And I thought ventile was supposed to be a "pure" fabric. It makes you wonder, but then what does waxed cotton do with a spark, I've never found out and I am not at all sure I would want to as you would think they would burst into flames wouldn't you.

My current jacket is pretend waterproof (that is what I call any so called breathable waterproof fabric, goretex or lookalikes) When exposed to a fire it stinks like a smoked kipper but I have not known it to suffer from any ignition problems. It's a cheap and nasty Gelert and cost me no more than 50 quid which is as much as I ever want to pay for a jacket. I bought it because it had half decent pockets which none of the hi tech and expensive Berghaus, North face and what have you has. If it falls apart, for 50 quid it hardly matters.

I know I may come across as thicker than a TV weather-girl with this, but I really don't know what ventile is.
Well, I know it's a cotton-based fabric, but I don't know what makes it 'ventile' as opposed to 'cotton'. When I hear the word 'ventile' it makes me think 'man-made'. But it's not? So what is the difference between cotton and ventile?

My guess for the spark resistance of waxed cotton would be its thermal mass effect - that is it feels cold to the touch, presenting a layer of wax to the surface rather than a mass of individual fine fibres which we normally aim for when creating fire.

In speaking to Andy Woodward of Cambrian Adventure (Mid Wales based Ventile wizard), much of what we know as "ventile" is known in the trade as "Etaproof" and made under licence to be sold as ventile - I have little doubt that even this prestigious material is going through a development to make it cheaper to produce by way of increasing profits for its makers, and therby being blended with other fibres while retaining its name.

"Ventile® is not coated or laminated yet the combination of the dense weave and the swelling properties of the fibres when wet provide excellent weatherproofing.
It is an entirely natural product that offers a unique level of comfort, look and feel as well as being windproof, highly breathable, very durable and quiet."

From their home page?

The stuff used by SASS is US sourced, I believe, but is also long staple Egyptian cotton with 30 per cent more material than conventional cotton. Its not Ventile because Ventile is a trade name but it performs in a more or less identical way.

My Sass smock was supplied proofed but luckily it has escaped sparks so far. The proofing does wear off after a little while.

The rule of thumb is: if water beads, then there is some kind of proofing involved. One question, is the Nikwax cotton proofer, being water based, flammable?

No - you are thinking CARBON fluorocarbon.... commonly known as CFCs
Different beastie....

Agreed, PFOS/PFOA is a somewhat different beastie, but even the more sedate fluorocarbons are a bit iffy (and I would not put it pas marketing to call PFOS "fluorocarbon" in the hope to miss some of the bad rep). CFCs is yet a third class of compound.

And my concern was based on e.g. the Swedish Chemicals Agency report (http://www.kemi.se/upload/Trycksaker/Pdf/Rapporter/Report7_06.pdf, yes, it is in English), so I'm in fairly good company in being concerned.

After reading this i got me an offcut of Ventile and put a lighter to it. Not long after i put the flame to it, the ventile did not burn through as such but went like char cloth.

Really shoddy service from Snowsled there. I was thinking very seriously about going for a double layer top from them... not now.

I stand corrected - I was basing my comments on fabric trade reports.....:(

A direct flame is more intense than a spark though. If you have some spare, could you shower sparks from a firesteel onto a piece?
